  • A critical analysis on multifaceted benefits of mixture of cover crops over pure stand
    Zupanič, Marko ; Kramberger, Branko
    Winter cover crops (WCCs) are fast-growing and high biomass producing crops that are included in the of crop rota- tion between two main cash crops. WCCs are used for greening the soil and can ... increase the yield of the main crop by increasing soil organic matter (SOM), soil water infiltrability and reducing water runoff and erosion, decreasing the weeds population and other soil-borne harmful biotic agents, improving soil microbial community, and enhancing agroecosystem services; however, yield can be adversely affected if they fix excessive nitrogen and do not release it in a timely manner. The carbon/nitrogen (C/N) ratio achieved in soil greening is a major factor in the availability of soil nitrogen, regardless of the location of soil residues; therefore, one option is to increase the nitrogen content of WCCs by sowing a mixture of legume and non-legume crops, since non-legumes such as grasses typically have a low nitrogen content and little to no positive effect on soil nitrogen availability on subsequent crops. The combination of legumes and non-legumes as WCCs exhibit multifaceted benefits such as quality biomass production, crop diversification, efficient plant protection, enrich- ment of soil microbes, biological nitrogen fixation, and so on. The integration of WCCs grasses and legumes into the crop rotation increases rational nitrogen management and can also increase SOM content and, consequently, soil fertility. The effective release of mineral nitrogen into the soil along the time should be taken into account in order to minimize leaching and optimize the symbiotic N fixed for the subsequent cash crop. Finally, with WCCs, it is possible to produce high-quality animal feed in pure stands and in mixtures in order to obtain on sustainable farm forage resources.
