|COMPOSITION||7% water-soluble calcium oxide (CaO) by weight.|
|USES||The use of CALVIP provides crops with calcium while reducing soil salinity and excess salts, improving the availability of water for the plants. By aiding the exchange of the sodium ion (Na) for the calcium ion (Ca), its pronounced ion exchange action allows improvement of the soil structure and favours the elimination of sodium. It also provides 6.4% of fulvic acids from lignosulfonates, which maintains and improves the soil structure, increasing its permeability.|
|DOSES AND HOW TO USE||Doses depend on the exchangeable sodium percentage (ESP), the electrical conductivity, the physiological needs of the plants and the type of crop.
The dose as saline soil corrector, through localised irrigation, is 40-60 l/ha and 60-90 l/ha, and can be increased, depending on the salinity, to 150 l/ha in fl ood irrigation.
For saline soil correction dose at a rate of 25-75 cc/m3 of water. To improve the structure of sandy soils apply 10-15 l/ha, to improve the structure of loam soils apply 15-20 l/ha and to improve the structure of clay soils apply 20-25 l/ha.
The dose as calcium corrector is 20-60 l/ha in localised irrigation and 40-100 l/ha in fl ood irrigation. Doses will depend on the quantity of assimilable calcium in the soil and the needs of the plant.
|USAGE PRECAUTIONS||Do not mix with strongly alkaline products or with sulphates or phosphates.
