CALVIP

7% w/w Water-soluble Calcium Oxide (CaO).

The application of CALVIP provides crops with calcium whilst reducing soil salinity and excess salts, thereby improving water availability for plants. Its pronounced ion-exchange action, by facilitating the exchange of sodium (Na) ions for calcium (Ca) ions, helps to improve soil structure and boost sodium removal. It also contains 6.4% fulvic acids derived from lignosulphonates, which maintain and improve soil structure by increasing its permeability.

The application rates depend on the percentage of exchangeable sodium (PES), electrical conductivity, the plants’ physiological requirements and the type of crop.

The correct dosage for correcting saline soils via drip irrigation is 40–60 L/ha and 60–90 L/ha, depending on the level of salinity. For flood irrigation, the dosage may be increased up to 150 L/ha.

For saline water correction, add 25–75 cm³ per m³ of water. To improve the structure of sandy soils, apply 10–15 L/ha; for loamy soils, apply 15–20 L/ha; and for clay soils, apply 20–25 L/ha.

As a calcium corrector, the dosage is 20–60 L/ha for drip irrigation and 40–100 L/ha for flood irrigation. The dosage will depend on the amount of available calcium in the soil and the plant’s requirements.

Do not mix with strongly alkaline products, sulphates or phosphates.
