Effect of irrigation and anions introduced in the form of magnesium salts on selected biochemical quality indices of sandy soil / Wpływ nawadniania oraz anionów wprowadzonych w formie soli magnezowych na wybrane biochemiczne wskaźniki jakości gleby lekkiej

Abstract

In this study, the effect of irrigation and anions introduced in the form of Mg(NO3)2, MgCO3 and MgSO4, which are biochemical indices of soil quality. Two laboratory experiments using complete randomisation were performed. First, one-factor experiment was carried out in triplicate. In this experiment, anion introduced with magnesium salt was the factor. The second experiment also was carried out in triplicate. In this experiment, the soil column for laboratory investigations of irrigated soil was used, anion introduced with magnesium salt was the first factor, and thickness of the soil layer was the second factor. The prepared material was irrigated nine times. In soil samples, the activity of dehydrogenases, proteases, alkaline phosphatase, amylase, and catalase was assayed. Based on these results, the biological index of fertility and enzyme activity number were calculated.
