Assessment of soil fertility - basis of balanced power of nutrition plants |
|
|
The analysis of spatial variability of indicators in the agro-podzolic heavy-loamy soil of the land plots of the Perm GATU, located in the Perm region of the Perm krai, is carried out. It was found that within one field the coefficient of variation of agrochemical indicators ranged from 10 to 67 %. The ratio between the elements of nutrition in the studied soil is sharply violated, so for a balanced plant nutrition it is necessary to make nitrogen, potassium, zinc and copper fertilizers.
