The purpose of this paper is to observe and reevaluate the influence mineral and organic fertilizers have on soil reaction. Various dosages of fertilizer have been applied, chemical as well as natural (manure) and comparisons were made regarding their influence, depending on the culture system (intensive and superintensive) without changing the dosage, but taking fruit tree density per hectare into account. Research in this paper was carried out on an experimental field at the Didactic Station of the U.A.S.V. M. B. in Timişoara during 2016-2017 and later in the research laboratories of the Departments of Soil Science and Agro-chemistry of the Faculty of Agriculture in Timişoara. The soil on which the experiment is placed, is a chernozem, moderate gleized cambic, weakly decarbonated, clayey, on medium fine loss layers. The experiment is polyfactorial, type 2 x 6: factor A – the crop system: a1 – the intensive system; a2 – the superintensive system. Factor B – doses of fertilizer. The experiment includes 12 alternatives. Each alternative includes 4 trees, between the alternatives have been left two trees for insolation, between the repetition have been left four trees. In conclusion, a slight soil acidifying was accounted for, with the intensive system as well as with the superintensive one, on applying a combination of mineral + organic fertilizers. Also, the soil pH shows lower values in both culture systems when a higher dosage of mineral fertilizer is applied.
