In this study data from agrochemical analysis of 200 agricultural soil samples collected from different locations in Republic of North Macedonia are presented. The soil samples were analyzed in order to determine the status of agricultural soils for active pH in correlation to the availability of humus and readily available forms of phosphor (P2O5) and potassium (K2O), for the purpose of understanding and promoting good agricultural practice and environment protection.
Mapping and spatial distribution of studied parameters showed that 15% of soil samples had an active soil pH lower than 6.50, 59% a pH higher than 7.5 and 26% had an active pH reaction 6.5-7.5, as optimum range for agricultural production. The results for available P2O5 content showed that 53.2% of soil samples were low in content of readily available phosphorus, while 53% of soil samples were evaluated as rich in readily available K2O. The most of soil samples were very poor in humus content and only 13% showed good supply with humus. Phosphorus (P), however, showed a certain degree of dependence from the pH of soil solution, as the analyzed soils samples with pH lower than 6.5 showed very low content of readily available phosphorus.
This study implies that continuous, timely and planned control, analysis and interpretation of soil quality are needed in order agricultural producers to use soil resources more efficiently with optimized fertilizer dosages which will bring higher yields, reduced production costs and improved quality of agricultural crops.
