Ustreznost konzervirajoče obdelave različnih tipov tal

Hari, Martin (author), Kocjan Ačko, Darja (mentor)

Konzervirajoča obdelava tal (ang.: conservation tillage) je postopek, ki opušča uporabo pluga. Je varovalna metoda brez obračanja z rahljanjem tal. Setev poteka v zastirko iz odmrlih rastlinskih ostankov, ki so lahko ostanki od prejšnjega posevka ali podsevka. Rastlinski ostanki zmanjšujejo erozijo in zablatenje tal, prav tako pa pospešujejo tudi biološko aktivnost tal. Delovna intenzivnost se zmanjšuje glede na vrsto, pogostost in globino obdelave tal. Cilji tega pa so stabilna, nosilna in zato tudi dobro vozna tla, zaščitena pred zgoščevanjem tal. Konzervirajoča obdelava je taka obdelava, ki v primerjavi s konvencionalnim načinom obdelave zmanjšuje vetrno in vodno erozijo. Po obdelavi naj bi bilo prekrito vsaj 30 % površine z rastlinskimi ostanki. Pri takšni obdelavi je tudi manjša možnost za nastajanje plazine, manjše pa je tudi tveganje ter morebitne zamude optimalnih rokov setve zaradi neugodnih vremenskih razmer.

Abstract

Conservation tillage is a tillage approach that reduces ploughing intensity. It is a protective method used for growing crops without disturbing the soil through tillage. Seeds are sown into dead mulch consisting of crop or undersown crop residues. Plant residues reduce soil erosion and crusting and promote biological activity of the soil. The working intensity is reduced depending on the type, frequency, and depth of tillage. The goal is stable soil that has high load-bearing capacity and is protected from soil compaction. Compared to conventional tillage conservation tillage reduces wind and water erosion. This tillage system maintains at least 30% of the soil surface covered by residue after planting. It also reduces the possibility of plough pans well as the risk of missing out on the optimal sowing date due to poor weather conditions.
