METHOD OF RESTORATION AND IMPROVEMENT OF FERTILITY OF LOW PRODUCTIVITY OF LIGHT-BROWN AND BROWN SOILS BY GROWING HIGH-PROTEIN CROP OF CHICKPEAS Russian patent published in 2015 - IPC A01B79/02 A01C21/00 

FIELD: agriculture.

SUBSTANCE: method comprises subsurface tillage by heavy disc harrow BDTM-3.8 at a depth of 12-14 cm. In the spring the cover harrowing by heavy harrow ZBT-1.0 is carried out as two tracks across the direction of the main tillage. Before sowing, the pre-sowing cultivation is carried out at a depth of seed embedding. The chickpea seeds are thoroughly cleaned and adjusted to sowing conditions. This is followed by pre-sowing seed treatment with bacterial preparation Rizotorphine in a dose of 250 g/ha and growth stimulators Albit at a dose of 4 g/t, Novosil 3 g/t, Apin-Extra 3 g/t seeds on the background of application of nitrogen-phosphorus fertiliser N₃₀P₄₅. The optimal depth of seed embedding is 6-8 cm, the soil temperature at planting is 12-14°C. For weed control, the post-emergence harrowing is carried out with light or moderate harrows.

EFFECT: method enables to increase productivity, to reduce the density of soil consistency, and to create an agronomically valuable fine lumpy soil structure.
