Experiments with a view to establishing the influence of different preceding crops: clover, lucerne, vetch-oats mixture, their green material used for green manure and farmyard manure on clay loam soil fertility and productivity of cereal sequence were conducted at the Lithuanian Institute of Agriculture's Joniskelis Research Station over the period of 1996-1999. Results of the trials showed that the largest amount of root and plant residues was left in the soil after ploughing down lucerne (11.6 t/ha of dry matter) and after clover (9.2 t/ha of dry matter). Different green manure increased the productivity of cereal sequence by 6.2, farmyard manure - By 8.1, compared with the trial without fertilization. More productive was cereal the sequence with winter wheat grown for two years, than the sequence: winter wheat-spring barley
