High efficiency micronized leonardite suspension

SOIL

• Improves soil structure.
• Releases nutrients from the soil
• Greater moisture retention
• High capacity to ionize metals making them available to plants

PLANT

• Improves plant growth and quality
• Stimulates root growth
• Enhances photosynthesis, respiration and protein synthesis
• Improves the effectiveness of fertilizers, synergistic effect with foliar nutrients, particularly with NHDelta

MICROBIOTIC

• Healthier soils
• Activate the rhizosphere
• Increases biological activity in the soil

•  Clay particles normally lay together in a flat structure with sodium ions present in low levels loosely attracted to the negatively charged face.
• The presence of the sodium ions neutralises the repulsive forces between clay particles causing the soil to become more dense.
• With increasing salt (sodium) levels the electrostatic charge is redistributed allowing the clay platelets to move closer together forming a tight three dimen-sional structure that is very dense and difficult for water to penetrate.
• The addition of Humic Acids such as Leodita sequests ions such as sodium re-instating the negative charge on the clay particles loosening the soil structure allowing the normal structure to re-establish.

Leodita is a complex suspension derived of naturally occurring
Leonardite, offering a source of high levels of humic and fulvic acids and lesser quantities of ulmic acids and humins.

Leodita includes a proprietary blend of 100% biodegradable non-ion-ic surfactants offering wetting, sticking and spreading properties.

Leodita promotes the absorption and transport of nutrients and, in particular, essential minerals and trace elements. Humic acids are well recognised as having complexing/chelating properties that enhance the uptake of minerals leading to improved crop health and resilience in stress conditions.

The product is suitable for application to soil or as a foliar product.

• Humic acids such as Leodita contain carboxyl groups and these bond with the positively charged clay particles.This breaks the attractive forces between clay particles.
• This action is called protective colloidal action and loosens the soil enabling water penetration.
• The effect of humic acids on clay soils becomes more noticeable with time – it may take 6 months before the full effect is seen.

• Metallic salts tend to be more soluble if they are made from organic acids.
• As an example magnesium phosphate will be bound in the soil due to its very low solubility. It is therefore unavailable to migrate to the root zone and cannot be taken up by the plant.
• In order for the plant to absorb nutrients from the soil it secretes organic acids (gibberellic, Indole acetic, humic acid etc.) from its root structure.
• These dissolve the metallic salts such as magnesium and are then reabsorbed through the semipermeable membrane of the roots back into the plant.
• This process will only be localised around the root zone leading to a depleted area around the root. Addition of Leodita to the soil allows a supply of minerals from a greater area around the root to become available to the plant.
• This is called sequestering – making the insoluble metal soluble and making nutrients outside the root depletion zone available to the plant by facilitating nutrient movement

All Ecoculture products undergo extensive stability testing to establish proven shelf-life of 2 years.

As a soil conditioner, 1-2 Litres per hectare applied pre-emergence.

• Humic acid slows water evaporation from soils, especially in sandy soils.
• Cations absorbed by humic acid, such as potassium partially ionize.
• This results in the cation (K, Mg etc) becoming slightly positively charged.
• A water molecule is dipolar and electrically neutral but the oxygen atom is slightly negative and so is then able to loosely bind to the positive cation (Na+, Mg+ etc).
• The hydrogen (negative) end of the water molecule then becomes partially neutralised increasing the hydrogen ends positive attractive force.
• The oxygen (negative) end of another water molecule then binds with this hydro-gen (positive) end and this continues until the attractive force of the first water molecule to bind to the positive cation is dissipated.
• This process effectively locks water into the soil.
• This can reduce water evaporation by up to 30%.
