Humic Acid Compound Fertilizer--Black Urea
1) Specification

2) Packing: 25kg /PP. woven bag or 25kg / paper bag with inner plastic lining
3)Capacity:20MT/20'FCL
- About 20-30% N volatility due to sunlight and weathering.
- About 30-40% N running off and leached out due to very wet condition.
The Problem when using White Urea
When using white Urea, the fact is almost 63% of the fertilizer applied in the field is lost due to:- About 20-30% N volatility due to sunlight and weathering.
- About 30-40% N running off and leached out due to very wet condition.
In the above cases, the crop could not utilize Nitrogen from Urea and in most cases the crop suffers
Nitrogen Deficiency resulting in very low yield, also leads to soil caking.
Nitrogen Deficiency resulting in very low yield, also leads to soil caking.
Effect Compared with white urea
Adopting advanced blending and stabilizing technology, our slow-release black urea contains humic acid,
Nitrogen, trace element, and other necessary nutrients.
Nitrogen, trace element, and other necessary nutrients.
Humic Acidhas the functions of complexing, ion exchange, adhesion and chelating metal ions under
alkaline conditions, and can improve Nitrogen utilization efficiency
alkaline conditions, and can improve Nitrogen utilization efficiency
1.Long Term Effect
Mixing with humic acid, the black urea will not easy to leaching and losing. The effect duration is much
longer than normal white urea.
longer than normal white urea.
2. Slow Release and Improve Nitrogen Utilization
Reduce the loss and fixation of nitrogen, Improve utilization of nitrogen.
Retains Nitrogen and nutrients in the root zones and releases them properly to plants when required.
3. Improve Soil Fertility And Buffering Properties
Effectively prevent soil caking. Increase microbial activity and exchange capacity of the soil.
Particularly suited to high rainfall areas, irrigated production systems or dry land production systems etc.
low fertility soil. Especially suited to field crops.
low fertility soil. Especially suited to field crops.
4. Reducing Farm Inputs& Increasing Production
It can reduce fertilizer application rates by 15-35% and increase yield by 10%-30%.
