The organically - farmed soil not only had deeper topsoil but also significantly
higher organic matter content and suffered less soil erosion than the conventionally farmed soil.
High organic matter content also helps to avoid soil acidification.
As mineralization processes proceed much faster on ferralitic soils in the tropics and subtropics than on soils typical to temperate and continental zones,
a high organic matter content and high biological activity are the pre-requisite for sustainable soil fertility.

The results of chemical analysis of soils samples collected before planting and harvest of the strawberries indicates that the
organic matter content in the soil of the
organic system was
higher than that of the non-
organic system (see table below).
The review of relevant research conducted by Stolze et al. (2000) concludes that under European conditions
organic agriculture has beneficial effects on the characteristics of soil
organic matter because the soil
organic carbon
content is
higher on organically farmed soils than on conventional ones.
Organic matter content is usually
higher in organically - managed soils, indicating
higher fertility and stability of
organic soils as well as moisture retention capacity, which reduce the risk of erosion and desertification.
The findings contradict the widely held view that soils with
high water
content necessarily accumulate
organic matter better than dry soils, which could have implications for agricultural and wetlands conservation practices, Hall said.
A
high content of
organic matter from certain composts, manures, or fertilizers will provide the necessary nutrients for fruitful plants.
