Abstract [eng] Field experiments were carried out at the Vėžaičiai Branch of the Lithuanian Institute of Agriculture on an Albi-Endohypogleyic Luvisol (LVg-n-w-ab). The study was aimed to explore the residual effect of phytomass of differently-managed perennial grasses, as green manure, on the improvement of soil properties and on the productivity and phytopathological condition of spring barley grown in a crop rotation in the second year of effect. The greatest amounts of plant residues were found to be left in the soil after differently-managed lucerne (19.48 and 17.29 t ha-1) and red clover of the 2nd year of use (13.06 t ha-1). With phytomass, the soil received 294.6, 262.6 and 228.2 kg ha-1 of nitrogen, 31.0, 26.5 and 24.8 kg ha-1 of phosphorus, and 154.2, 133.6 and 129.3 kg ha-1 of potassium, respectively. The C:N ratio of the aboveground mass of perennial grasses was the lowest and more favourable for a more rapid decomposition (10.0–14.0) than in the residues (roots and stubble) (20.0–36.0). Nutrients, released during mineralization of phytomass of perennial grasses of the second year of use, had a positive effect on spring barley grown in the second year of effect after green manure incorporation.
