Effect of cultivation technologies of spring wheat, barley, and broad beans on the agrochemical properties of soil
The effect of different cultivation technologies of field crops on the accumulation of mineral macro- and microelements in the soil during the period from 1983 to 2003 was exmined. The content of available phosphorus increased by more than 2.5 times. The content of exchangeable potassium increased, although to a lesser extent; the variation between the different technologies was insignificant. It was found that the content of humus in the soil tended to increase at the use of high-input, biological, and moderate technologies during the period considered.
