Brief Introduction
What is leonardite ?
Leonardite is a kind of natural organic macromolecule polymer. It is the high molecular uncertain polymer compound formed from the decomposition of plant residue and transformation of microorganism through tens of millions of years or even hundreds of millions of years, or a series of physical and chemical effects of the earth. It is also an important source of humic acid raw materials.
What is C.E.C?
Cation exchange capacity refers to that C.E.C, in a certain pH value (=7), the total number of moles (potential CEC) of the exchangeable cations (K+,Na+, Ca2+,Mg2+,NH4+,H+,AI3+,etc) containd in each kilogram of soil.
C.E.C is one of the most important index to measure the quality of humic acid, in other words, the higher the C.E.C, the better the humic acid activity; for the same content of the product, the higher the C.E.C, the better the effect of water and fertilizer retention capacity, the more obvious effect it has on the plant.
Leonardite advantage:
1. The content of organic mater is up to 85%, and the content of humic acid 70% min.
2. The content of C.E.C is up to 400-450 meq/100g.
3. Large storage capacity, with total reserve of about 18 million tons.
4. It contains fulvic acid of 3%-5%
Application
Agriculture and Forestry: Organic Fertilizer, used alone in Turfgrass; Compound with other fertilizers to produce N.P.K fertilizer, raw material of plant nutrition liquid. Agents of pesticides,soil,and stock breeding,etc.
Building and construction: Concrete retarder, Environmentally friendly coating agent, Decoration material, etc.
Water resources protection: Supply water purifier, Sewage proposal. Erosion proof and scale remover.
Oil field service: Oil drilling, Fluid loss agent, Anti-collapse agent, etc.
Application Recommendation
Turf Grass | 25-30kg/100m2 |
Cereal, beans maize | 350-500kg/ha apply with NPK Fertilizer |
Citrus, apple, and other fruits | 1-2kg per plant at 3 months interval |
Tuber potato, sweet potato chilli, tomato | 10-20kg/m2 as based and 1st application of fertilizer 10-20kg/m2 as baser |
Field vegetables | The same as above |
Green house (tomato, cucumber) | 10-20kg/m2 as based and 1st application of fertilizer |
* 5-10kgs/ha/time, 2-3 times during seedling and growth stage, better to be applied with N, P fertilizers
* Mixed with Nitrogen fertilizers: 5% of total blend i,e, 5kgs of Potassium Humate per 100kgs of Urea
* Used as muti-functional compound and basal fertilizer, top dressing, seed fertilizer and foliar fertilizer
