Abstract

The paper presents the results of a five-year study of the impact of various agricultural technologies (No-till, minimum and traditional using moldboard ploughing) on the content of mineral nitrogen in Haplic Chernozem in southern zone of Rostov Region. It has been revealed that the content of ammonium and nitrate nitrogen in the winter wheat areas cultivated by various agricultural technologies does not significantly change in samples collected both in spring and in summer. However, the content of nitrate nitrogen under resource-saving technologies (both minimum and Notill) has been higher than under ploughing throughout the whole period of study. The trend identified has not been mathematically confirmed. Nevertheless, the impact of No-till technology on the intensity of ammonification and nitrification should not be unequivocally denied, since a significant amount of mineral nitrogen is extracted by crops, and their crop yields under minimum and zero tillage was higher, than when ploughing was applied.

Highlights

Soil is one of the most important natural resources
The results obtained indicate that the intensity of ammonification when using various cultivation methods is almost the same (Figure 2)
The supply of plants with nitrogen depends on the rate of decomposition of the soil organic matter to compounds assimilated by plants

Summary

Introduction

Soil is one of the most important natural resources. High soil fertility is the basis for the existence of the civilization on our planet. Agriculture uses the soil as a substrate to produce crops through the application of mineral fertilizers and significantly limits its ecological function in the biosphere, disrupting the vegetation cover, reducing the humus content, and significantly polluting with pesticides, heavy metals, oil and other substances. The most important element of the technology that affects soil fertility and crop yields is the primary soil cultivation, which has a wide range of methods from traditional ploughing to No-till technique with many options for boardless cultivation and various minimization conditions.
