Possibility of increasing the efficiency of preparation of soil and sowing of winter cereals with elements of precision agriculture

Koncept precizne poljoprivrede vrlo je širok, a najčešće se pojašnjava povećanom učinkovitošću postignutom pomoću precizne navigacije, digitalnih karata i odgovarajućeg softvera. Različite studije širom svijeta pokazale su znatnu uštedu potrošnje goriva i vremena tijekom obrade i sjetve tla koja se temelji na izostavljanju preklapanja i učestalosti okretanja na kraju polja. Za manje farme, koje obično koriste trometarske radne strojeve (kultivator, gruber, valjari) smanjuje se potrebno radno vrijeme do 15,7 % i ušteda goriva do 8,66%, a na strojevima od šest metara do 12,6 % vremena i 8,28 % goriva. Glavni razlog je smanjenje širine preklapanja vožnje koja u uvjetima ručne vožnje obično predstavlja od 6,5 do 9,5 % nazivne radne širine. Korištenje preciznih poljoprivrednih tehnologija omogućuje također bolje planiranje i analizu radnih postupaka.The concept of precision farming is wide, and it is represented with the efficiency achieved with the help of precise RTK (Real Time Kinematic) navigation, digital maps and appropriate software. Different studies around the world reported considerable fuel and time saving during soil tillage and seeding which based on omitting the overlapping and the frequency of turning round at the end of fields. For smaller farms, which commonly use 3 m working machines (cultivator, chisels, disc harrow) up to 15.7% of the time and 8.66 % of the fuel can be saved, while on 6 m machines up to 12.6 % of the time and 8.28% of fuel is saved. The main reason lies in the reduction of overlapping width which in manual driving conditions usually represent about 10 % of nominal working width. The use of precision agriculture technologies allows us to better plan and analyze the working procedures
