Issue 24/2020 - New zeolite technology to remediate soil and improve the quality of agricultural products

A few days ago, two new technologies independently developed by Jiangsu Fubang Bioenvironmental Protection Technology Co.
, Ltd.
use zeolite technology to repair soil and improve the quality of agricultural products, and develop a new field of
zeolite application.

The two new technologies are: a preparation method and application of modified zeolite compound as soil conditioner and a preparation method and application
of zeolite bio-organic fertilizer.

Zeolite is a general term for zeolite group minerals, which is an aluminosilicate mineral containing alkali metal or alkaline earth metal, which has the functions
of sterilization, deodorization, adsorption of heavy metals and pesticide fertilizer residues.
In the two new technologies, zeolite bio-organic fertilizer uses modified zeolite, fermentation residue and amino acid liquid as the main raw materials, and adds Bacillus subtilis and Bacillus licheniformis
.
Experts attending the meeting believed that the bio-organic fertilizer was modified by zeolite and added trace elements to effectively improve the fertilizer function
.

At present, zeolite bio-organic fertilizer has been applied in 11 provinces and cities, with an annual sales volume of 5,000 tons
.
The results show that the application of zeolite organic fertilizer can increase the soil moisture of the cultivated layer by 1%~2%, improve the water and fertilizer retention of the soil, improve the soil structure, and increase the yield of vegetables and crops by about
20%.
