Effect of Agricultural Navigation Without RTK Correction on Spring Sowing

Abstract

It is carried out a comparative investigation of seed drill guiding accuracy in two ways. In the first way the drill is guided by a conventional disk marker and in the second way - by agricultural navigation without RTK correction. It is found that the usage of agricultural navigation lead to more straight rows and reduction of the fuel consumption, but the distance between drill tracks exceeds the row width about 26 %, because of low level of navigation accuracy.

Uporedno ispitivanje preciznosti setvene navigacije je izvedeno na dva načina. U prvom testu sejalica je navođena konveniconalno upotrebom diskosnog markera, a u drugom testu putem poljoprivredne navigacije bez RTK korekcije. Utvrđeno je da upotreba poljoprivredne navigacije vodi do pravilnijih redova i smanjenja potrošnje goriva, ali i da razmak između prohoda sejalice prekoračuje širinu između redova za oko 26% zbog niske preciznosti navigacije.
