Establishment of Grass Strips for Maintaining Biodiversity in Agroecosystems

Main principle of the common agricultural policy of European Union is achievement of high results with the least possible negative impact on the environment, land protection and efficient use of natural resources. For that purpose, a number of studies are carried out, related to the improvement of biodiversity and protection of the pollinators in the areas of production. Two type of grass mixes were observed: “Laitamag” (Hungary) composed of White mustard (Sinapis alba L.), White clover (Trifolium repens L.), Phacelia (Phacelia tanacetifolia Bentham), Crimson clover (Trifolium incarnatum L.), Egyptian clover (Trifolium alexandrinum L.), Red clover (Trifolium pretense L.), Wild oats (Avena sativa L.), Alfalfa (Medicago sativa L.), Buckwheat (Fagopyrum esculentum Moench) and Sainfoin (Onobrychis viciifolia Scop.) and a mix, proposed by the Agrarian University: White mustard (Sinapis alba L.), White clover (Trifolium repens L.), Phacelia (Phacelia tanacetifolia Bentham), Buckwheat (Fagopyrum esculentum Moench), Coriander (Coriandrum sativum L.). The vegetation of the autumn crops began in March, as the blossoming lasts for 60-63 days, from the beginning of April until 24 June. For the spring sowing (18 March), the flowering of the mixes occurred later, in the second 10-day period of May and ended at the end of June. As a result of the low temperatures during winter, the white mustard, buckwheat and sainfoin plants perished. White clover proves to be the most resilient species.
