Diversitatea biologică a agroecosistemelor în dependenţă de tehnologia de cultivare a plantelor de cimp

Abstract

Short rotation and monoculture diminish biological diversity of agroecosystems and decrease their productivity and stability. There are three groups of harmful objects (pests, pathogens and weeds) and the most powerful one are the weeds, which endanger the complete production in case of minimization of the base, work of the soil and under unfavorable meteorological conditions
