Description
The article examines the results of studies on the study of changes in the structure of leached chernozem in the low-west agro landscape, depending on the technology of cultivation of field crops. The research task was to determine the effect of basic tillage (dumping plowing, non-loosening loosening and surface treatment) and fertilizer systems (mineral and organic in crop rotation) on the structure (aggregate composition of the soil) of the old irrigated leached chernozem. It was established that the aggregate composition of the arable layer when cultivating tilled crops (sugar beet, soybean and corn) was noticeably inferior to the structure of the treated layer under crops of solid crops (winter wheat, alfalfa). The content of agronomically valuable soil aggregates for roaches varied from 39.8% in corn to 53.4% in soybean. At the same time, the structural coefficient was 0.7-1.1. Cultures of continuous sowing increased the content of agronomically valuable soil aggregates of the arable layer by an average of 12.2%, and the structural coefficient by 0.6. The replacement of plowing with non-loosening loosening and surface treatment in crop rotation showed that in the arable layer of the aggregated soil particles under the tilled crops practically did not change. This figure was 47.3 and 48.5%, while in plowing it occupied an intermediate position - 48.3%. Under the crops of continuous sowing a tendency to increase agronomically valuable aggregates was noted. The mineral fertilizer system fully worked to preserve the structure of the soil when it was used for plowing. The remaining methods of basic processing against the background of the mineral fertilizer system are less effective. According to the arable crops there was a tendency to increase aggregates of 10-0.25 mm in size. Winter wheat (according to its predecessor - corn and alfalfa), alfalfa of different years of life increased the austerity of the arable layer by 9.0%. Organic fertilizers, introduced twice in the rotation, significantly improve the soil structure in the plow layer. The organic system used for tilled crops in comparison with unmanned crops for plowing, non-rooting and surface loosening increased the number of aggregates measuring 10-0.25 mm on average by a rotation of 10.4. Organic fertilizers in the link of the crops of continuous sowing improved the aggregate composition by an average of 4.3%. Optimal organic fertilizers worked against the backdrop of non-loosening loosening

Description
The article considers data obtained in long-term stationary experiment in Kuban state agrarian University, which was started in 1991 for old irrigated leached black soil of the central zone of the Krasnodar region. Studies were conducted in two rotations of seven-field grassy-grain-row crop rotation. The duration of irrigation - more than 30 years. It is established that long-term irrigation by sprinkling led to the soil over-compaction in both arable and subsurface layers. In the arable layer of 0-30 cm density of 0.14-0.17 g/cm3 exceeds the maximum allowable. We have noticed a sharp decrease in humus in the arable layer to 2.46-2.67 per cent. The weak acidification of the active root layer was noted, salt PH 5.0-5.3. In the soil-absorbing complex, the content of calcium decreases. It was found that the productivity of crops cultivated in the rotation of two rotations was greatly influenced by the system of basic soil treatment. In the first rotation, the decrease in productivity of cultivated crops against the background of the surface treatment system amounted to an average of 4.2% compared with deep: subsurface tillage and moldboard. In the second rotation after 14 years against the background of shallow surface treatment crop rotation productivity decreased by 11.2 %. The dependence of the fertilizer system and crop yield on the background of different main soil tillage is established. When using the mineral fertilizer system, the decrease in crop productivity, while minimizing the main tillage in the second rotation was 15.2%, and against the background of the organic fertilizer system by 12.7%. The deep sub-soil treatment provided an increase in the productivity of old irrigated leached black soil in the second rotation against organic fertilizers by 3.6%. Thus, the organic system of fertilizers on the background of deep main soil tillage allows to obtain crop yields in the framework of grassy-grain-row crop rotation on wetlands degraded old-irrigated lands is not lower than using high doses of mineral fertilizers
