How does organic farming help in soil conservation?

They contribute positively to soil water retention, support a variety of organisms vital to the decomposition and cycling of nutrients, provide crops with essential nutrients and can maintain carbon reserves, contributing to the mitigation of global climate change. Conservation tillage, which is another method of organic agriculture, also reduces soil erosion. It prevents soil degradation, such as erosion and impact.

Organic farmers

are encouraged to adopt this method because it has the power to conserve the top layer of soil, which is a fundamental component of organic farm products.

Organic treatments reduced the average sediment supply by 30%, or 0.54 t ha−1 h−1, compared to conventional treatments. This study investigated soil erosion rates under simulated events of heavy in-situ rainfall in the Swiss agricultural and tillage systems experiment (FAST, Prechsl et al. In this state, physical influences apparently overlapped with biological effects due to the greater supply of energy to microbes, which could lead to changes in the spatial distribution of microorganisms and organic substrates within a given soil structure.

reduced soil loss for radishes by 18% as a result of high biomass density and weed cover at the end of the growing season.

From a soil conservation perspective, reducing tillage operations will further improve the ecological impact of organic agriculture systems. We measured multiple vegetation parameters of crops and weeds from conventional and organic farms grown with beans, potatoes, radishes and cabbage in a mountainous hydrographic basin in South Korea. Organic agriculture reduces soil erosion compared to conventional agricultural systems, as a result of greater soil surface cover and SOM content in organic agriculture. Therefore, research on this topic is important for evaluating and potentially improving soil erosion control in different agricultural systems (Hösl and Strauss, 201.We used mixed linear models to create a model that would map the measurable fractions of soil organic carbon in the hydrographic basin).

Hartman K, van der Heijden MGA, Wittwer R, Banerjee S, Walser J-C, Schlaeppi K (201) Cultivation practices manipulate the abundance patterns of members of the root and soil microbiome, paving the way to intelligent agriculture. Therefore, we used long-term weather station data to account for the variability of monsoon storms and we simulated different scenarios to include variable planting dates and harvest operations for different row crops and agricultural systems. In this experiment, livestock manure was applied as fertilizer to organically managed plots, while in conventionally managed plots, mineral fertilizer was used. This finding could be explained by the 2-year herbaceous clover law, which was cultivated between winter wheat and corn within the FAST rotation and is known to increase SOM in agricultural soils (Loaiza Puerta et al.

Barré K, Le Viol I, Julliard R, Chiron F, Kerbiriou C (201) Reducing tillage and herbicides mitigates the gap between the effects of conventional and organic agriculture on the foraging activity of insectivorous bats. During a single heavy rain event in this experiment, sediment delivery between streams in organic plots was reduced, on average, by 0.54 t ha−1 h−1 compared to conventionally managed homologous ones. Producers of certified organic crops and livestock manage their farms in accordance with USDA organic regulations. .
