Biologization of reproduction of Sakhalin soil fertility.

Abstract

The effect of mono- and polycomponent crops of different-species sideral crops as a means of preserving soil fertility has been studied experimentally. A short-term and partial increase in the content of carbon and nitrate nitrogen in the soil was noted. The siderates are positively evaluated as a means of increasing the content of phosphorus and potassium. The effect of sources of organic matter of annual cabbage, cereals, legumes and their mixtures is sufficiently leveled. The C : N ratio indicated a weak efficiency of the siderates as a green fertilizer. Sederal crops are considered as a means of biologizing agriculture by acting on soil properties as one of the sources of organic matter.
