Humic acids
What is humic acid?
Humic substances can be found in all soils and waters and arise from vegetable decomposition. A fertile soil contains maximum 3 % peat and about 3-10 % humic acid. In a certain layer, which has not reached the stage of brown coal yet, you can find them in a concentration up to 85%. This soft brown coal layer is called internationally “Leonardit”. Since the discovery of high concentrations of humic acid in this soft brown coal layer it has drastically raised their commercial viability. The humic acid stimulates the cell membrane as well as metabolism activities and thereby raises the germination rates. Also important plant enzymes are stimulated immediately. The strong root development supports the nutrient uptake capacity. The strengthened grass is clearly less susceptible to diseases.

Seed treatment with humic acids – double security
The technology used in the production of coated seed is a procedure which requires a lot of experience, time and instinct. Furthermore macronutrients and micronutrients are elementary components of a finely coordinated combination of different materials. Humic acids are introduced in a highly concentrated form which has 2 steps in the process. Firstly they are brought directly into contact with the seeds and are then integrated again at a later stage in the outer layer of the coating.
Humic acids:
Humic acids come into direct contact with the seeds, before they are coated with several nutritious layers. The grain is subjected to an intensive treatment (vaccination) with a highly concentrated humic acid solution. This method has the following effects:
✓ The cell membrane as well as metabolism activities are
stimulated and therefore increase the germination rate.
✓ The nutrient uptake
capacity is increased and promotes therefore the growth of the seedling.
✓
The sugar and vitamin content are raised
✓ The activity of the seedling is
promoted when a lower susceptibility to diseases is given.
Seed treatment with humic acids have following
effects:
✓ Enhanced nutrition uptakes
✓ Faster germination
✓ Quicker establishment
✓ Promotes root development of the seedling
✓ Reduction in the susceptibility to pests and diseases
