Halysh F. Agroecological features of primary cultivation in the short-term rotation on podzolized chernozem of western Forest-Steppe.

The object is the process of podzolized chernozem agroecosistem' change under influence of the basic processing of a ground. Methods of researches - field and laboratory. The complex action of the basic processing of podzolized chernozem in a combination to fertilizers in the short-term rotation on productivity of oats, soybean and maize yield, quality of a grain, the change of the microbiological, fermentative activity, soil fertility and weed infestation is stated. The ecological and energy estimation of different primary cultivation practices under oats, soybean and maize yield grain is considered. It is established, that the superficial processing of ground raised productivity of oats grain by 3,5 hkg/ha, and chiseling - by 3,2 hkg/ha as compared to ploughing (29,4 hkg/ha). The similar dependence was observed for soybean - accordingly 2,5 and 1,6 hkg/ha as compared with ploughing (20,4 hkg/ha). At superficial processing of ground in all the treatment in experiment the maize productivitydecreased versus the treatment in experiment with chiseling and ploughing approximately up to 4 %.
