Crop siderat as a method of biological function in the southwestern part of the central black-earth region

The article presents the results of long-term experience in study crop crops and their impact on growth conditions yield following crops. reaped siderates were sown after winter spring wheat a 4-field rotation. research work showed that it is less likely to get good shoots than wheat, total plant mass siderate introduced into soil over all years was 54-66 t / ha, which about 1.7 times lower culture. incorporation organic material most its cultivation provided positive balance humus. infestation next increased only when using mineral fertilizer by 1.4-1.7 compared without it, while number perennial dicotyledonous weeds an average 2.5-3 times, both applying azofoska it. rotation with predecessor peas for grain, not significantly higher siderates, predecessor, sideral pair slightly lower.
