WebWhat is the optimal amount of organic matter in agricultural soil ? The organic matter content in the soil is very important when it comes to soil bacteria viability. some studies... The concentration of SOM in soils generally ranges from 1% to 6% of the total mass of topsoil for most upland soils. Soils whose upper horizons consist of less than 1% of organic matter are mostly limited to deserts, while the SOM content of soils in low lying, wet areas can be as great as 90%. Meer weergeven Soil organic matter (SOM) is the organic matter component of soil, consisting of plant and animal detritus at various stages of decomposition, cells and tissues of soil microbes, and substances that soil microbes … Meer weergeven Vegetal detritus in general is not soluble in water and therefore is inaccessible to plants.
