Improved soil subsistence agent with low cost and slow release of fertilizer

Abstract

The soil improving agent with slowly released fertilizer and in low cost is prepared through dissolving 10 kg of urea in 150 kg of water, adding 240 kg of attapulgite, soaking for 24 hr, stoving at low temperature of 40 deg.c, crushing and pacing. The soil improving agent can inhibit the migration of salts in soil effectively, change aggregate structure of soil obviously, raise the oxygen permeability and water permeability of soil, and make fertilizer release slowly for favoring plant growth. The preparation process is simple and suitable for industrial production.

Description

technical field [0001] The present invention relates to an improved soil nutrient with low cost and slow release fertilizer. Background technique [0002] At present, in the desertification control and ecological environment restoration and construction in the west, the survival rate of planting trees and grass is not high. The loess in the west has very little organic matter, but the content of inorganic salts is very high. Improve the soil aggregate structure, reduce the salinity content, Increasing the nutrients necessary for plant growth becomes the key. The currently used intervention materials have high cost and single performance, which restrict their wide application. Contents of the invention [0003] The object of the present invention is to overcome the above mentioned drawbacks and provide an improved soil nutrient with low cost and slow release fertilizer. [0004] The technical scheme of the present invention is: an improved soil nutrient agent with low cos...
