anti-caking agent for soil, methods to prevent soil clumping and to improve plant growth

摘要

the present invention provides an anti-caking agent for soil, which includes, as effective ingredients: a lignin having a peak molecular weight, as measured by gpc molecular weight analysis using a uv detector at a wavelength of 254 nm, within the molecular weight range of 10,000 to 40,000; and a land of diatoms. the present invention also provides a method for improving the growth of a plant, which method uses the anti-caking agent for the soil described above. the anti-caking agent for the soil according to the present invention has the effect of reducing soil agglomeration and improving the poor growth of a plant.
