Influence of particle size and extraction time on soil pH analysis based on SPSS software

Abstract

Soil pH is an important index of the basic physicochemical properties of soil. In this paper, the effects of different soil particle size (0.9 mm and 2.0 mm) and extraction time (10 min, 30 min and 60 min) on the soil pH analysis were analyzed. SPSS software was used to analyze the data for significance analysis. The results showed that the particle size and extraction time had little effect on the pH value during the process of soil pH determination.
