<p>U regionu severnog Banata se uglavnom primenjuje<br />konvencionalni način obrade zemljišta, zasnovan na obradi<br />plugom, kao primarna obrada koji je spor, skup i zahteva veliki<br />utrošak rada i goriva. Takva obrada je sa ekološkog stanovišta<br />nepovoljna i neodrživa. U poslednjih trideset godina, naučna<br />saznanja o obradi zemljišta u svetu se menjaju u pravcu<br />pojednostavljenja obrade i smanjenja prohoda. Savremeni sistemi<br />obrade su u Srbiji nedovoljno istraženi, a cilj ovoga rada je da se<br />optimizuje obrada zemljišta za date uslove. Za potrebe istraživanja<br />je postavljen ogled u trajanju od tri godine (2011/2012, 2012/2013<br />i 2013/2014), pri čemu je uzgajan kukuruz, pšenica i kukuruz, tim<br />redosledom. Svaka kultura je uzgajana u tri sistema obrade:<br />konvencionalna obrada bazirana na plugu, direktna setva i<br />konzervacijska obrada bazirana na razrivaču, pri čemu je Ďubrenje<br />bilo uniformno. U radu je analiziran uticaj različitih načina obrade<br />na specifični otpor zemljišta, fizičke i hemijske osobine zemljišta i<br />živi svet u zemljištu (brojnost glista). Uspešnost poljoprivredne<br />proizvodnje se ogleda kroz ostvareni prinos i utrošena sredstva,<br />zbog čega je utvrĎen najprinosniji i ekološki najprihvatljiviji način<br />obrade zemljišta. Pored navedenog, analiziran je uticaj različitih<br />rasprskivača pri tretiranju useva pesticidima na prisustvo ostataka<br />pecticida u zemljištu</p> / <p>Conventional tillage is the most frequently applied tillage method in the<br />area of northern Banat. It is based on ploughing as the primary tillage<br />operation, which is slow, costly, and requires large expenditure of labour<br />and fuel. Such treatment can be ecologically unfavourable, and it is not<br />sustainable. In the last thirty years, global knowledge about soil tillage<br />has been changing towards simplification and reduced soil tillage.<br />Contemporary tillage systems in Serbia are not studied thoroughly<br />enough, but the goal of this work was to optimize soil tillage for the given<br />conditions. The trial was set up during the period of three years<br />(2011/2012, 2012/2013, and 2013/2014), in which corn, wheat, and corn<br />were cultivated, respectively. Each crop was grown using three tillage<br />systems - conventional tillage based on ploughing, direct seeding, and<br />conservation tillage based on tine cultivator, whereas fertilization was<br />uniform in all the systems. This dissertation analyzes the impact of<br />different tillage on soil resistance, physical and chemical properties of<br />soil, as well as biota in the soil (number of earthworms). Success of<br />agricultural production is reflected in yield and expenses, therefore this<br />dissertation determins the highest yielding and most environmentally<br />friendly system of tillage. In addition, it analyzes the impact of using<br />different kinds of nozzles in treating crops on the pesticide residues in the<br />soil.</p>
