With the increase of the use of heavy machinery in heavy marsh soil tillage,
the degradation of soil physical conditions like the formation of a hardpan is becoming a
problem. To improve such conditions, the effects of different tillage systems were
investigated.
The soil tillage is one of the greatest energy consumers in agriculture, and that is the
reason why an experiment with different tillage systems and their influence on fuel
consumption was carried. The compared tillage systems were the conventional tillage
and the conservation or reduced tillage. Conservation tillage systems can be an important
part of a sustainable agricultural system providing benefits for the farmers in terms of
labor and fuel consumption; however, yield variability may discourage and slow
adoption.
Effects of ploughing and subsoiling treatment on growth and yield of crops
depended on the weather and soil condition.
Using the right tillage system may contribute to raised the energy demand for
cultivation, increase profit, crop yields, soil improvement and protection of water
resources. Sa povećanjem korišćenja teških mašina u obradi teških zemljišta, degradacija
fizičkih osobina zemljišta, kao što je "taban brazde", postaje sve veći problem. Da bi se
ti uslovi poboljšali ispitani su efekti različitih sistema obrade.
Obrada zemljišta je jedan od najvećih potrošača energije u poljoprivredi, što je
razlog istraživanja različitih sistema obrade i njihovog uticaja na potrošnju goriva.
Upoređeni sistemi obrade zemljišta su: konvencionalna obrada i konzervacijska ili
redukovana obrada. Konzervacijski sistemi obrade mogu biti značajan deo sistema
održive poljoprivrede, donoseći pogodnosti proizvođačima kroz potrošnju rada i goriva,
iako varijabilnost prinosa može obeshrabriti i usporiti njihovo korišćenje.
Efekti oranja i razrivanja na rast i prinos useva zavise od klimatskih i zemljišnih
uslova.
Korišćenje pravog sistema obrade zemljišta može doprineti smanjenju potrošnje
energije za obradu, povećanju profita, prinosa i poboljšanju zemljišnih uslova i zaštiti
vodenih resursa.
