Characteristics of sod podzol soils after biochar application

Abstract

The effect of biochar implementation into sandy and loamy-sand sod podzol soils on the soil acidity, total water capacity and concentration of exchangeable and mobile potassium and calcium has been investigated. It has been found that the biochar application caused the decrease in the soil acidity and also increases of the water capacity and concentrations of exchangeable and mobile potassium in sandy and sandy loam soils. The favorable conditions for growing agricultural plants in sandy-loam soil could be created with application of 3 w. % of biochar, but in sandy soils it can be reached with 5 w. % of biochar.
