THE EFFECT OF LONG-TERM CROP ROTATIONS ON SOIL PROPERTIES IN SPRING BARLEY CROPS

Intensive farming and short crop rotations have encountered problems of soil degradation. Finding solutions to these as well new challenges requires returning old practices, adapting them current issues. In 1965, a field experiment (crop rotation collection) was set up at the Experimental Station Vytautas Magnus University, significance which not only did decrease, but became increasingly more relevant. The object research is spring barley crops in cereal, Norfolk, with row crops, intensive for green manure continuous bare fallow. aim investigate effect long-term combinations on properties crops. Crop perennial grasses or fertilization demonstrated positive properties. Improving agrophysical also improves biological chemical This tendency becomes apparent carried out than fifty years same place.
