Effect of intensification techniques on the structural state of chernozem during the cultivation of spring wheat |
|
|
The article presents the results of studies on the influence of intensification methods on the structural state of leached chernozem of the Krasnoyarsk forest-steppe during the cultivation of spring wheat. It is shown that blocky > 10 mm (26-38%) and lumpy-granular units 2-1 mm in size (15-21 %) predominated in the structural composition of chernozem. The use of the biological stimulant Lignohumate AM in the complex protection of spring wheat against the background of the pre-sowing introduction of ammophos in doses of N5P20 and N12P50 contributed to an increase in the number of 2-1 mm aggregates by 4-5 % compared with the control and the formation of an excellent structural state of chernozem containing aggregates of a valuable size 72- 74% during the growing season.
