The article shows the ninth year of research on the
remineralization of leached chernozem. In the
plants of winter wheat, the content of macro and
micronutrients of nutrition under remineralization
of leached chernozem was investigated. It is
established that when introducing rocks, the
content of food elements in plants rises
Remineralization of leached chernozem was carried
out by applying such rocks as loess-like loam, shell
limestone, apatite phosphogypsum. We have
revealed that the introduction of species didn’t
change substantially the content of boron during the
growing season. We have also displayed the seasonal
dynamics of macro variants of the experiment and
the increase in the content of food items in the phase
of active growth of winter wheat. Seasonal dynamics
of trace elements is expressed, but can not be
expressed with certain regularity
Remineralization of leached black soil was carried out by making such rocks as loess-like loam, shell limestone, apatite phosphogypsum. It was revealed, that the introduction of species did not change substantially the content of boron during the growing season. The manganese content in relation to the control increased by 13-15%, 25-30% for copper, zinc, 35-45%, 25-30% cobalt, and molybdenum in 2-3 times, and especially when combined application of rock. Seasonal dynamics was expressed, but does not give definite pattern
The effects of tillage, minimum and combined treatment on the structure of the southern black soil and crop yield of such winter wheat as Tanais, and Petrovchanka Ayvina have been studied. It is revealed, that the most stalwart and giving more than the number of productive stalks is a sort of Petrovchanka. The highest yield of winter wheat was obtained with plowing, and the lowest - with combined processing unit. The most productive variety was Petrovchanka.s
