Soil fertility control of state owned agricultural land in Vojvodina Province

Abstract

The paper presents the results of soil fertility control of the public land in AP Vojvodina. A total of 514 soil samples were collected in 2018 from the depth of 0-30cm. The majority of the collected samples (70%) had slightly alkaline reaction. Low-humus soil class was found in 54% of the samples, which indicated the need for harvest residue plowing down and organic fertilization, so as to enhance soil humus content and thus preserve soil fertility. The analysis of readily available phosphorus revealed an optimum P content in only one third, while optimum potassium content was found in all of the collected soil samples.

U radu su prikazani rezultati kontrole plodnosti zemljišta na području AP Vojvodine, koje u državnom vlasništvu. Tokom 2018. godine prikupljeno je ukupno 514 uzorka sa dubine 0-30 cm. Najveći broj uzoraka zemljišta (70%) ima blago alkalnu reakciju, što predstavlja potencijalno ograničavajući faktor u biljnoj proizvodnji. Klasi slabo humoznog zemljišta pripada čak 54% uzoraka, te je neophodno zaoravanje žetvenih ostataka i primena organskog đubriva kako bi se sadržaj humusa u zemljištu povećao, a time sačuvala plodnost. Analizom lakopristupačnog fosfora, utvrđeno je da samo trećina uzoraka ima optimalnu koncentraciju, dok je obezbeđenost zemljišta kalijumom optimalna.
