Abstract
In this article, the results of research on WRI of LUA Juodkiskiai experiment field (1999 - 2003) are discussed. Fertilize other factors influence over potassium fluctuation, its balance and leaching into drainage water during crop rotation are a In order to evaluate the potassium balance and its quantity passed together with rainfall, seeds, fertilizers and take with j (secondary and primary production) was established in plant residues and drainage water. When fertilizing with liquid manure, potassium balance was negative while growing perennial grasses as much potass: needed to mature their yield. The investigations established that potassium concentration in drainage water and its leachi increased by precipitation during the research period, and it was reduced by the amount of this element taking out with y.s geochemical environment had influence on the increase of potassium supply in soil. It was established that long-term fertilization with liquid manure had raised the potassium supply in soil. However, i ecological point of view potassium leaching did not cause any problems. In all treatments the potassium concentration in drains did not exceed permissible concentration.
