Advantages
  • Nitrogen free fertilizer with a high concentration of Potassium and Sulphur.
  • With a very low salt index, Select SOP is an ideal product for fertilization programs of crops grown in soils with high levels of salinity
  • In alkaline soils, the application of Select SOP tends to generate a decrease in pH into the root zone, facilitating greater assimilation of phosphorus and micronutrients.
  • Select SOP contains very fine particles (<0.015 mm) which are rapidly dissolved when preparing mother solutions.
Description

With a high level of Potassium and Sulphur, Select SOP is the ideal fertilizer for crops with high demand of these nutrients, fulfilling the plant’s need and preventing possible deficiencies. Select SOP is Nitrogen free, which makes this product suitable to be used in matching the needs of many crops, but particularly those ones where Nitrogen should be reduced at fruit ripening stage, maintaining the right N:K ration for this stage.

The low salt index provided by Select SOP, makes the product reliable in various type of soils.

Directions of use

Select SOP can replace any other source of potassium available in the market. It can be used in all crops, in all developmental stages, when extra potassium is needed. The product can be used in crops grown in both greenhouses and open fields. Avoid using the product in water containing high level of calcium! Use Select SOP in periods when high amounts of calcium nitrate are applied and N unbalance should be avoided. (Do not mix the products into the same tank!)

Recommended dilution rate = 7-10 kg / 100 liter water
