Effect of Furfural Residue on Control of Soil Alkalization and Amelioration of Solonetz

摘要

Furfural residue, an industrial waste, is a kind of strongly acidic organic materials. Its comprehensive utilization in agriculture showed a significant effect on control of soil alkalization, amelioration of solonetz and increase of crop yields. In detail it may adjust pH, depress alkalinity, reduce bulk density and compactness and increase water permeability and retention ability of the soil. Meanwhile agricultural use of furfural residue provided an effective way to avoid its pollution of the soil, Water and air.
