Abstract

Postoje tri načina gospodarenja tlom u svrhu poljoprivredne proizvodnje: konvencionalni, integrirani i ekološki. Način gospodarenja ima utjecaj, kako na kemijske parametre tla, tako i na fizikalne i biološke, a i ukupno na plodnost i kvalitetu tla. Konvencionalni način gospodarenja kao glavni cilj ima visoke i stalne prinose, a kako bi se to postiglo koriste se mineralna gnojiva, sredstva za zaštitu bilja i intenzivnu obradu tla. Ekološka poljoprivreda, za razliku od konvencionalne, ne koristi mineralna gnojiva i pesticide te je obrada tla reducirana. Kod trećeg načina gospodarenja, integriranog, koriste se sredstva za zaštitu bilja i mineralna gnojiva tek onda kada je to neizbježno. Prema načinu gospodarenja postoji pretpostavka da konvencionalna i integrirana poljoprivreda degradiraju kemijske parametre tla dugoročno gledano, dok ekološka poljoprivreda dugoročno poboljšava kvalitetu tla odnosno njegove kemijske parametre. Ovaj rad bazira se na detaljnom usporedbenom prikazu ta tri načina te je dan pregled provedenih istraživanja u kojima su se mjerila različita kemijska svojstva tla (pH, EC, organska tvar, mikroelementi, makroelementi…) s obzirom na korišteni način gospodarenja. Može se zaključiti da način gospodarenja zasigurno ima utjecaj na kemijske parametre tla gdje najmanji negativan utjecaj ima ekološka poljoprivreda. Također, konvencionalna poljoprivreda može degradirati kemijska svojstva tla, ali degradacija kemijskih parametara je manja ako se pri gospodarenju tla pridržava određenih normi i ako iza proizvodnje stoji znanje.

Abstract (english)

There are three systems of soil management for the purpose of agricultural production: conventional, integrated and ecological. Choice of system has an influence on chemical, physical and biological, and also on overall fertility and quality of the soil. Conventional method as the main objective has high and constant income and to achieve that it uses mineral fertilizers, plant protection products and intensive soil treatments. Ecological agriculture, unlike conventional, does not use mineral fertilizers and pesticides, and soil treatment is reduced. In the integrated method plant protection products and mineral fertilizers are used only when it is inevitable. According to the soil management, there is a presumption that conventional and integrated agriculture degrades chemical parameters in the long term, while ecological agriculture improves the soil quality in the long run. This paper is based on a detailed comparison of these three methods. So far, a number of studies have been published in which the effects of used agricultural system based on different chemical parameters (pH, EC, organic matter, microelements, macroelements ...) have been investigated and their overview is also provided in this paper. It can be concluded that the choice of agricultural system certainly influences on the chemical parameters of the soil where the least negative impact has ecological agriculture. Also, conventional agriculture can degrade chemical properties of the soil, but the degradation of chemical parameters is lower if soil management complies with certain norms and if knowledge is behind production.
