Humic Acid Granular Form

Specifications

It reduce salinity of soil, improve water holding capacity of soil, increase fertility, and enhance crop physiological activity.

Humic Acid Granular Form

 

Property:

Humic Acid is a principal component of humic substances which are the major organic constituents of soil, (humus), peat, coal, many upland streams, dystrophic lakes and ocean water. It is produced by biodegradation of dead organic matter. It is not a single acid, rather, it is a complex mixture of many different acids containing carboxyl and phenolate groups so that the mixture behaves functionally as a dibasic acid or, occasionally, as a tribasic acid. Humic acids can form complexes with ions that are commonly found in the environment.

  

Quality Standard:

Humic Acid content (dry basis)	50%min
Moisture	20%max
Organic item	60%min
PH	5-6
Partical size	2-3mm

 

Effect:
Sharply increase the utilization efficiency of mineral fertilizers in soil; Preventing NPK from leaching or lock up; Promote good soil structure formation; Increase the capacities of water holding and cation exchange and improve aeration condition; Stimulate activities of soil microorganism; Detoxify pollutants in the soil.

 

Application Method:

As ground fertilizer, it’s the major application of this product which can be applied alone or combined with Nitrogen and Phosphorus before seeding or planting. It’s particularly suitable for the following types of soils:

1) Alkaline soil with low iron content

2) Sandy soils with low organic (humus) content

3) Acid podzol soils with low humus content, simultaneously liming to soil

4) Saline soils

5) Lime soils.

Dosage: 8 --12 kg/ha
