Applying of machinery and mechanisms in soil cultivation by subsoiling and trashing: Effects and consequences

Abstract

This paper deals with specific and important effects of machinery and mechanisms in deep soil cultivation by subsoiling and trashing. Soil cultivation by trashing working bodies improves water conservation in soils, their fertility and yields and significantly affects total energy consumption. Energy consumpation, effects and consequences which occured in soils are significant parameters in adoption of machinery and tractors for trashing, especialy dry soils. Nowdays, reduced tillage, because of economic reasons, signifficantly influence plant production effects, first of all crop yield. Rational solutions of machinery and technologies in this field require serious research.

U radu su opisani značajni i specifični faktori uticaja primene mašina i agregata u postupcima duboke obrade zemljišta podrivanjem i rastresanjem. Duboka obrada zemljišta razrivačkim (podrivačkim) radnim telima sa zadatkom poboljšanja procesa konzervacije vlage u zemljištu i plodnosti zemljišta i prinosa, značajno utiče na ukupnu potrošnju energije. Potrošnja energije ostvareni efekti i posledice koje nastaju u zemljištu su značajni parametri kod izbora mašina i traktora kojima se obavlja podrivanje i rastresanje posebno u nedostatku vlage u zemljištu. Poslednjih godina redukovana obrada zemljišta iz poznatih razloga (ekonomska kriza) značajno utiče na efekte biljne proizvodnje, prvenstveno prinose poljoprivrednih kultura. Racionalna rešenja mašina i tehnologija u ovoj oblasti zahtevaju ozbiljna istraživanja.
