Application rates

For sports turf application use 1,5 – 2 Kg / Ha in 300 L water per Ha per application. Apply in 14 day intervals. After each application, let the product dry for 3 – 4 hours to allow absorption through the leaves. Do not switch off the stirring mechanism during transport to the field and during the spraying process.

When used on soils with low organic matter and/or low natural mineral content in the soil, more frequent application and/or higher application rates per Ha are recommended. For specific applications, consult your distributor for more information.

How does it work?

The soil colloid has degrees of affinity for various basic cations. This bonding increases with larger atomic weight, ion size and amount of charge. The percentage saturation for each of the cations will usually be within the following ranges for optimum performance.

The process of cationic exchange begins when water and basic cations (Ca, Mg, K, Na) meet the soil colloid. Based on the soil colloid’s degree of cation affinity, Calcium (Ca) will attach to the soil colloid releasing the smaller cations. The released cations (Mg++, Na+, K+, H+) are solubilized in the soil solution and made available to the plant or removed from the soil profile. As hydrogen is released from the soil colloid into the soil solution, acidity is reduced and pH is raised.
