Examples of natural organic fertilizers include manure, slurry, earthworms, peat, seaweed and guano. Green manure crops are also grown to add nutrients to the soil. Natural minerals such as mine rock phosphate, potash sulfate, and limestone are also considered organic fertilizers. Blood meal, feather meal, fish meal, bone meal and crab meal are some examples of organic fertilizers of animal origin.
This type of fertilizer is usually high in nitrogen and the rate of nutrient release varies between medium and fast. Blood meal is high in nitrogen, with 13 percent of this important plant nutrient along with 1 percent of phosphorus. However, the smell of blood meal can attract animals to the garden, so dig into the soil to avoid this undesirable side effect. If the plants in your orchard keep dropping leaves, taking on strange colors, and generally not thriving, it may not be your gardening techniques that are to blame.
There could be an imbalance in soil structure that is killing the plants in your garden. In such cases, improving soil fertility could simultaneously improve your chances of having a successful garden. However, it's always a good idea to test the pH levels and soil acidity in your garden before you start applying fertilizer. Too much of a good thing can be just as bad as a hands-off approach.
For example, phosphorous, which is a major component of most fertilizers, will only work in a certain pH range. Adding unnecessary nutrients or organic material can also cause environmental problems, as these compounds are washed away by heavy rains and pollute nearby waterways. Subscribe to the Epic Gardening podcast on iTunes or Spotify Like most organisms, plants need a variety of nutrients to grow properly. These soil microbes are normally present in healthy soils.
When they aren't, plants suffer. Fertilizers were created to compensate for any soil deficiency, so that things can be grown in less than ideal spaces. However, the main nutrients found in fertilizers are nitrogen (N), phosphorus (P) and potassium (K). They also usually appear on labels in that order.
Of course, the difference between synthetic and organic fertilizers doesn't seem significant, but you'll see differences, especially in the long term. Synthetic fertilizers are known to degrade soil quality over time, harming human health in the process. You constantly need more synthetic fertilizers to improve your garden. Not only do these compounds make the soil more acidic, but they also keep beneficial earthworms away.
Not the best choice for organic gardening. Regular plant watering can even push the nutrients in these compounds far enough away from plant roots to adversely affect root growth. In addition, synthetic fertilizers are often made from non-renewable resources rather than organic matter. Organic fertilizer for plant well-being is more effective.
What is compost? Organic fertilizers improve microbes in the garden soil where they are used. Not only do they help retain water, but they also lighten the soil so that more air is available for plant roots. They don't waste nutrients like chemical fertilizers. Nor are they likely to create a buildup of salts that could slow plant growth.
These types of fertilizers even tend to be less likely to burn tender plant roots than synthetic products. The slow nature of organic fertilizers is beneficial if you're looking to improve the soil in your garden over time. However, this aspect can be a drawback if you're looking for instant results. Liquid fertilizers or foliar sprays are a good organic compromise when plants need a sudden increase in energy.
Gardeners should also know that organic fertilizers are biologically active, unlike inactive inorganic fertilizers, which can also come from natural sources. This means that your components may change over time and may vary slightly with each batch. They are not as consistent as chemical fertilizers, but high-quality organic fertilizers are more bioavailable to plants. This is why they are perfect for organic gardening.
You should be careful when it comes to buying fertilizer. Products that claim to be “organic” at first glance may not really be. Be sure to read product labels carefully. A good way to assess the accuracy of the statements is to compare the one you intend to buy with the list from the Organic Materials Review Institute.
However, if you are not a commercial producer, keep in mind that all of the products listed here are also considered organic. Exactly what it says on the tin, dry fertilizers are often mixed with the soil. These organic fertilizers can be used in both in-ground gardens and container-grown plants. Fertilizer types in the dry organic matter category are generally added as a way to encourage the long-term growth of seedlings, transplants and crops.
Usually, their goal is to improve the structure of the soil. Obviously, these are liquid organic fertilizers that are applied as fertilizer for the soil or as feed for the leaves. They can also use a type of binding agent to help the plant or soil structure in question better absorb them. These fertilizers can be poured into the soil surrounding the plant so that they can be absorbed into the roots.
Or they could be sprayed onto the leaves instead. After all, foliar (foliar) sprays are particularly useful for vegetables during their season. Liquid fertilizers are generally considered good organic fertilizers for actively growing plants and should generally be applied monthly. However, leafy crops may need to be sprayed every two weeks.
However, you can still practice organic gardening while regularly applying organic matter fertilizers on a consistent schedule. While they are not fertilizers in and of themselves, these substances help plants to absorb the nutrients they receive from other places. Some of them, such as seaweed, are also a great source of trace elements. However, paying to have these elements included in fertilizer can be a waste of money, as healthy soil should already contain useful organic matter, such as microbes, enzymes and humic acids.
However, if you want to combine your own for a specific gardening need you have, you can also do so by combining different sources of organic matter in a single solution. Just be careful not to overdo it so as not to burn plant roots or even kill sensitive plants. When used correctly, they are great for a garden and attract beneficial insects and bugs, unlike chemical fertilizers. Now we have come to the list of organic fertilizers.
There may be some that act as high-nitrogen organic fertilizers, while others are more high-phosphorous fertilizers. All are considered organic because of their origin. Organic gardening fertilizer comes in tons of shapes and sizes. Read this to determine which biofertilizer is best for your garden.
Alfalfa is an organic fertilizer that is commonly used as part of livestock feed. However, alfalfa flour is a natural fertilizer that is simply ground to break down faster. This particular organic fertilizer has low amounts of nitrogen, phosphorus, and potassium. As a result, alfalfa meal improves plant health at a moderate rate compared to other organic fertilizers.
In organic gardening, these are best used as soil conditioners in early spring before planting. It is an excellent organic fertilizer for vegetables, since it acts as an abundant slow-release crop if you grow it and then cut it and drop it between vegetable plantations. Among organic fertilizers for plants, this source is often used in agricultural fields, as nature intended. The organic nutrients in this fertilizer have a lot of nitrogen, but they also contain reasonable amounts of potassium and phosphorus.
The disadvantages of cottonseed meal are that it acts slowly and that it is mainly available in cotton-growing areas. In organic gardening, this fertilizer is particularly useful for conditioning gardens in autumn, before planting cover crops or before applying mulch. This gives cottonseed meal time to fully decompose, so that the nitrogen present is readily available in spring. Corn gluten meal contains traces of nitrogen, phosphorus and potassium.
It's also a good soil stabilizer, but it works slowly, feeding beneficial soil microbes. Therefore, you should add it in the fall so that it has time to decay during the winter. However, if you add it during an active organic gardening season, know that it won't burn plant roots. Rock phosphate is made from rocks that have been crushed.
It contains large amounts of phosphate, as well as other essential nutrients. The main advantage of using this fertilizer is that the elements it contains do not dissolve in water. Instead, they stay in the ground until the plants that grow there use them. This is perfect for someone with an organic gardening practice who strives to be environmentally sensitive.
Animal waste, in general, has a high mass-to-nutrient ratio. However, it contains respectable amounts of nitrogen, phosphorus and potassium. Cow manure (also known as livestock manure) also works in gardens at a moderate speed. All of these elements help make it an excellent compost additive.
However, some weed seeds can survive being digested by the cows in question, and this can cause obvious problems. You should also avoid leftover manure from industrial operations because it contains a lot of salt. Fresh manure that hasn't been composted enough provides too much nutrition to plants and can burn the roots. Even regular manure can end up burning plants if used too much or if used too often.
In organic gardening, use manure sparingly. Having a lot of poultry litter or chicken manure on hand doesn't mean you're getting comparatively high levels of nutrients. Even so, poultry or chicken manure contains slightly higher amounts of the three main plant nutrients than cow manure. It is often considered to be the organic fertilizer with the highest nitrogen content.
It also works in a somewhat faster way. The best time to use poultry or chicken manure is right after harvesting crops or just before starting another gardening cycle. As with cow manure, you should be careful with chicken, turkey or poultry manure, as it can burn plants if applied too much. This starter fertilizer is one of those soil modifiers that supports soil organisms that increase nitrogen uptake in the roots of plants in your garden.
Green sand comes from ancient seabeds. This high-calcium fertilizer also contains iron, potassium and other trace elements. However, the nutrient levels in glauconite (green sand) products may vary depending on their source. The nutrient profile of compost varies depending on what is placed, but is often close to that of manure.
It's a popular garden fertilizer and perhaps the best organic fertilizer out there. This is never in doubt because it can be done for free and works at a moderate pace. There are also a variety of ways in which compost can be used in your garden. Can be used as mulch or mixed with soil in your garden.
It can also be prepared as compost tea for use as foliar food. Gardeners who don't have room for a large compost system can even get similar benefits from using worm compost bins under their sinks. However, compost can be alkaline in nature. This feature negatively affects the ability of plants that live in the soil to absorb nutrients.
Compost also has a high weight/nutrient ratio available. Poorly maintained compost piles can also emit bad smells, which can cause city residents to quickly get into trouble with their neighbors. This is especially true when sewage sludge is composted for a short period of time and used in gardens. Human manure must be composted for at least a few years before using it in a garden.
If you are still planning to use it, you should add compost before or after planting. It's also a good soil refresher between growing seasons for gardens that are constantly being used. You'll need to use half an inch to a full inch each time a new crop is planted. If you have constant problems with your plants after applying the compost, do a soil test to see if you can identify if the problem is the compost.
Soybean meal is a high-nitrogen fertilizer that also contains low amounts of phosphorus and calcium. Local growing conditions tend to affect how quickly this product is absorbed into the soil, but this process normally occurs at moderate rates. However, soy meal is quite useful as a long-term soil conditioner. This fertilizer is created from the powdered blood of slaughtered cattle.
While high in nitrogen, blood meal is low in other elements. It's also very acidic and is likely to burn plants if used too much at once. You should definitely proceed with caution. It's best to apply blood meal to the soil a little before planting anything in it.
Even so, the fast-acting nature of blood meal makes it a good tonic for sick plants. You'll need to pour this fertilizer over the plant roots according to the instructions on the package and then, possibly, cover everything with mulch. It's no wonder that bone meal is made from ground cow bones. This high-phosphorous fertilizer also contains plenty of nitrogen.
It works at moderate speeds to stimulate flower production and root growth. As a result, it is an excellent plant food for flowering plants, bulbs and fruit trees. However, it is mainly used as a soil amendment for places with high levels of nitrogen where plants are constantly being burned. However, it is sometimes a better plant food than those made with synthetic chemicals when applied correctly.
Feather meal is very rich in nitrogen. However, it does not contain calcium or phosphorous and only works at moderate speeds. If you plan to use this fertilizer in your garden, use it before planting to give the soil a boost of nutrients. If you're wondering if it's the right time to apply this fertilizer, do a soil test first.
Seabird guano is collected on islands with low rainfall and arid climates, both factors that help retain high levels of nutrients. Seabird guano contains high levels of trace elements along with decent amounts of nitrogen, phosphorus, and calcium. In fact, it is considered to be one of the best organic fertilizers in the world, especially beneficial for remedying a nutrient deficiency in a garden. Bat guano is a fast-acting fertilizer that contains a wide variety of nutrients such as nitrogen, phosphorus, calcium and several other minerals.
Bat guano is not as rich in these components as seabird guano, but beneficial organisms find it more easily available in garden beds, as they promote healthy growth. Since some of the nutrients in bat worm are soluble in water, this fertilizer is probably most effective when used in liquid form such as foliar spray or compost tea, as opposed to chicken litter. You can also apply it between crop plantings and as soil refreshment in late spring. This product is made from partially decomposed fish.
As a result, it often has a fishy smell (although the AgroThrive brand smells a bit like soy sauce and isn't unpleasant). Fish emulsion fertilizer is high in nitrogen but contains little or no calcium or potassium. It is also very acidic and should be used lightly to prevent plants from being burned. However, it works immediately once applied, which makes it a good treatment to increase organic matter in leafy species with low nitrogen levels.
However, some plants may not tolerate it very well. This fertilizer is made from shredded seafood byproducts. It contains plenty of calcium and some phosphorus, as well as a large amount of trace elements. Shell meal also contains an element called chitin, which helps ward off annoying nematodes.
This is a liquid fertilizer for seaweed created through cold processing. Kelp contains small amounts of the three main components of the fertilizer, but is high in trace elements. It's also a good source of growth hormones that can help plants reach their full potential by supporting root development. This liquid fertilizer is usually mixed with water and used as a foliar spray or poured onto the soil around plants.
Seaweed is a fast-acting fertilizer that is often freely available on most coasts. It contains all three major nutrients in small amounts, but it also contains a lot of zinc and iron. Seaweed is considered to be very beneficial for cereal crops, as well as for those that need high levels of potassium. It's hard to beat grass clippings as a low-cost fertilizer, since they're usually free.
This substance can be used to prevent weeds and conserve soil moisture. However, the nitrogen content in each batch varies. A 1- to 2-inch layer should be sufficient for a full growing season. Just don't use grass cuttings that have been grown with herbicides.
Cuttings can act as a slow-release substance for plant roots as they decay. If you want a nitrogen fertilizer that is organic and contained in your garden system, this is the place. Azomite, among other crushed rocks, are technically inorganic fertilizers, since they come from mineral sources. You can find this ground rock powder in granular form that is released slowly or in faster-acting forms.
Azomite is the by-product of inorganic fertilizers from mining in certain old volcanic areas of Utah. It provides trace elements to the soil, instead of acting on the macronutrient content of the soil. Most often, it is introduced into the soil as a conditioner or added to compost. Interestingly, this is the byproduct of human urine that is produced after the human body breaks down proteins into amino acids.
The use of urine as fertilizer is not uncommon, and plants often benefit from a dilute solution of urea in water. However, there are many times when it is not the best idea to use it in gardens. Try to check out our article on this same topic before opting for urea. When you buy through links on our site, we may earn an affiliate commission.

For example, guano, dried and powdered blood, ground bones, crushed shells, finely ground fish, phosphoric rock, and wood. When you start working in the garden, there are a few basic elements that most people already know: your plant will need soil, water, and sunlight. Sunlight only requires the proper placement of your plant. But isn't the floor a one-time thing? Do you fill a container or a raised bed with good soil and end the day? Unfortunately, no.
That's where fertilizers come into play. Find out why fertilizers are important, the difference between organic and synthetic fertilizers, and 12 organic fertilizers for your garden. The three main nutrients (known as macronutrients) that plants need are nitrogen (N), phosphorus (P) and potassium (K). Fertilizers add these nutrients back to the soil and usually appear on the fertilizer package as N-P-K.
For example, a fertilizer that has the 10-5-5 list would mean that the fertilizer contains 10% nitrogen, 5% phosphorus and 5% potassium. There are two types of fertilizers: organic and non-organic (also known as chemical or synthetic). Organics, in this context, include fertilizers approved for organic gardening, which are both organic (such as compost) and inorganic (such as rock dust). These fertilizers are considered safe for organic gardening.
Not all natural materials are considered safe for organic gardening, so they are excluded. Compost is a decomposed organic material that can be re-added to the soil to help plants grow. You can even make your own compost while minimizing your waste. You can compost fruit and vegetable scraps, coffee grounds, crushed eggshells, and more.
If you don't want to have your own composter, you can also buy compost bags at a local nursery or at places like Lowes and Home Depot. Compost requires a moderate amount of time to break down and add nutrients to the soil. Blood meal is an excellent source of nitrogen. It also provides nutrients to plants fairly quickly.
Personally, I like to use Down to Earth's Blood Meal, but there are other options available. It comes in granular form and helps plants to stay green and lush. It also increases the soil's acid level, which lowers the soil's pH level. This is one of the organic fertilizers where you can overdo it and burn your plants, so it's important to follow the instructions.
Bone meal is a great source of phosphorus and calcium. I use Down to Earth's Bone Meal. Bone meal can help prevent apical flower decay and it also helps if you find that the flowers fall off before they bear fruit. Bone meal takes longer than blood meal to break down and add nutrients to the soil.
Comfrey is high in nitrogen, phosphorus, potassium and calcium. If you grow comfrey, you can take cuttings and soak them in water for a few weeks. Then you can thin it out and add a little bit to your plants. A little goes a long way, and it tends to smell bad as you let it soak in water.
However, I've heard good things about comfrey tea and other compost teas that allow nutrients to be absorbed quickly. Comfrey clippings can also be composted or simply tilled into the ground. Fish emulsion is a good source of all three macronutrients, with a higher concentration of nitrogen. It provides immediate nutrients to plants, unlike some fertilizers that take a long time to decompose.
It has a slight smell, but I personally can't smell it the next day. It also includes more trace elements. Bat guano is a source of all three macronutrients. It is moderate to immediate in terms of how quickly it provides nutrients to plants.
Bat worm also helps to adjust soil pH and improves soil texture. Alfalfa flour helps add all three macronutrients, along with many trace elements. They take a few months to decay and be absorbed by plants. Alfalfa flour are fermented alfalfa plant seeds.
You can usually find alfalfa flour in feed and animal stores. It can also be used to speed up compost piles. OK, you understand me, technically they are 2 different organic fertilizers. But it's worth noting the differences so as not to confuse the two.
I originally thought they were the same thing: ground rock. There are several rock powders available and all of them help add nutrients to the soil. Rock phosphate is a good source of phosphorus and calcium. Azomite rock dust is naturally extracted volcanic rock dust and is composed of more than 70 minerals and trace elements.
Organic fertilizers are different types of fertilizers derived from plant matter, mineral matter, animal matter, etc. Unlike some organic fertilizers that take a while to break down, liquid algae add nutrients that are immediately available for plant use. In addition, organic fertilizers increase microbial activity, helping to release other nutrients in addition to those provided by the fertilizer. Organic fertilizer raw materials are natural ingredients and are often by-products of another industry.
Because organisms need an adequate temperature and sufficient water to perform their work, the effectiveness of organic fertilizers is limited by these factors. When you adopt the concept of organic fertilizer, your plants and crops will experience a balanced, nutrient-rich ecosystem that can function according to natural expectations. Organic fertilizers usually provide many micronutrients, as well as the main nutrients for plants, nitrogen, phosphorus and potassium. Before nutrients can be released into the soil, microorganisms need to break down the organic components.
However, fish emulsions and some other organic fertilizers release their nutrients quickly and are exceptions to general guidance on the time of application. .
