Influence of green manure crops on biogenicity and physical and chemical properties of soil

Zelena gnojidba jedna je od mjera za popravak fizikalno kemijskih i bioloških svojstava tla. Primjena ovoga načina popravka tla poznato je od davnina, a danas zbog promjene klimatskih uvjeta ovaj način popravka tla postaje sve važniji. Zelena gnojidba omogućuje obogaćivanje tla organskom tvari, vezanje hraniva u tlu, sprečavanje njihovog ispiranja, zaštitu tla od erozije, povećanje biogenosti tla, očuvanje vlage u tlu i popravak strukture tla. Poljoprivredni proizvođači za zelenu gnojidbu odabiru usjeve koji se mogu uklopiti u svaki plodored, a mogu se sijati cijele godine i biti: predusjev, međuusjev, podusjev, pokrovni usjev. Odabir usjeva u navedene svrhe ovisi o tipu tla, o biljnoj proizvodnji, količini oborina, karakteristikama i ulozi usjeva za zelenu gnojidbu.Green manure is one of the measures to repair the physicochemical and biological properties of soil. The application of this method of soil repair has been known since ancient times, and today, due to changing climatic conditions, this method of soil repair is becoming increasingly important. Green manure enables soil enrichment with organic matter, binding of soil nutrients, preventing their leaching, protecting soil from erosion, increasing soil biogenicity, preserving soil moisture and repairing soil structure. Farmers for green fertilization choose crops that can fit in any crop rotation, can be sown troughout the year and be: foreskin, intermediate crop, sub-crop, cover crop. The selection of crops for the stated purposes depends on the type of soil, on the crop production, the amount of rainfall, the characteristics and the role of the crop for green manure
