Effect of small stones removal at tillage potato soil

Abstract

While analysing the methods of removing small 3-30 cm diameter stones from soil and investigating them, the following objects of the experimental research were identified the effects of stone removal from the soil, crushing stones smaller than 6-8 cm in diameter and spreading them on the soil on the potato productivity, tubers quality, reduction of arable layer. Mentioned method of removing small stones was constructed by authors and used science 1970. Crushed stones in the soil have a diffenet effect on various crops yield, however, the did not have any negative effect on potato yield wireduction the range of the tested amount of stones at least. Comparing with other known methods, separation of loamy compacted soils by crushing stones small than 6-8 cm in diameter and removing of larger stones have a lot of important advantages. Stones are eliminated from the whole ploughlayer, less soil is being removed from the field and compactedVytauto Didžiojo universitetasŽemės ūkio akademij
