The Evolution of The Soil Fertility in the Borș Town, Bihor County, in The Period 1987 - 2021

Abstract

The town of Borș occupies a total area of 43.4 Km2, of which about 35.4 Km2 are occupied by agricultural land. In order to study the evolution of soil fertility, analyzes were carried out in the period 2020-2021 on the main trophic indicators of the soil: the pH value, the phosphorus content and the potassium content. The analyzes were performed only at the level of the arable layer. In order to estimate the evolution of the soils, the cartograms drawn up on the entire surface, based on research and laboratory analyzes in 2020, the cartogram of PH values, the cartogram of the state of potassium supply and the cartogram of the state of phosphorus supply were compared with the cartograms of the same indicators, drawn up at the level of 1987.

Keywords: fertility, TEO units, cartograms, supply status, soil units
