BALANCE OF NUTRITION ELEMENTS IN GRAIN-STREAM ROTATION OF LONG-TERM STATIONARY EXPERIENCE
According to the results of the long stationary study on light-gray forest soil of the Baikal area, the indicators of the yield of spring wheat and spring barley with prolonged systematic use of chemical fertilizers are presented for the first time. The estimation of the balance of nutrients in grain-stream rotation depending on the dose of fertilizers and crop yields is given. It is found that the cost of elements of nutrition of kg per 10 centners of grain were higher in the version with the integrated fertilizer of N60Р40К60 kg/ha. The used organic mineral system of the experience provides zero and positive balance of elements of nutrition in the versions with the application of the corresponding types of fertilizers.
