Issue 41/2013 - Single-machine commissioning of Luxi Chemical's sulfur-coated slow-release fertilizer

Luxi Chemical sulfur-coated slow-release fertilizer stand-alone commissioning

Recently, Shandong Luxi Chemical Group successfully tested the slow-release fertilizer project of the slow-release fertilizer project built by applying the sulfur-coated controlled-release fertilizer technology of Japanese Katakura Company
.
Long-term use of this slow-release fertilizer can improve the soil, and the empty shell after nutrient release can not only store water and moisture, but also play a role in aeration and fertilizer preservation, so that long-term compacted soil becomes loose
.

According to reports, the slow-release fertilizer produced by sulfur-coated controlled-release fertilizer technology has the advantages of
high fertilizer utilization rate.
Conventional fertilizers are less than 30%
of the nutrients actually used by crops through air evaporation, underground infiltration, and surface water washed away.
The controlled release of the outer coating material avoids the above situation, especially the nitrogen loss rate is significantly reduced, which can save 30%~50% of nitrogen fertilizer and make the nutrient utilization rate reach more than
60%.

One-time fertilization to meet the needs of crops throughout the growing season is another advantage of
this technology.
At present, crop fertilization is becoming more and more simplified, and one-time fertilization of crops has become quite common
.
However, the disposable fertilizer sold on the market is basically a fast-acting high-nitrogen compound fertilizer, which has the risk of
long seedling stage or late fertilization.
The controlled release fertilizer can be predetermined to design the release mode of fertilizer in the growing season of crops, so that the release law of fertilizer nutrients is consistent with the absorption of crop nutrients, so that the supply of crop nutrients is stable and regular
