Abstract: The investigations were carried out in the Lithuanian Agricultural University Water Research Institute land plots in the Endocalcari dDhypogleyic Cambisols (CMg-n-w-can). The basis of the investigation is 3 variants field experiment. Each variant consists of 3 in B ha drainage. The traditional arable farming is applied in variant I. In the variant II the land is not being cultivated, but in spring the perennial grass ('Lolium perenne L') is being seeded into the spring barley and kept till spring. In the variant III the land is not being cultivated sr the harvest and left for the rest till spring. The variant II is distinguished by the minimal mineral nitrogen content. Applied to cultivated and uncultivated land, the min N eves are increased 51-83 and 33 - 40 and 11 - 101 and (38 - 134%) (to 9.5 - 14.3 mg kg'1 and 152 - 68 and 154 - 61 kg ha"1). The average investigation of N concentration in the drainage water shows, that the minimum concentration of this element was in second variant. Applied to the traditional farming and uncultivated land, the N concentration is increased by (30 - 42% to 34 and ng l"1). By average data the min N, leaching by drainage water in the variant II was minimal and about 27 kg ha'1. Applied to the pie farming and uncultivated land, the min N leching is increased (30 - 55%) (to 35 - 42 kg ha"1)
