SQM's specialty products contribute to a higher water use efficiency. A right crop nutrition allows the plant to absorb nutrients in an adequate way, which leads it to require less water. Our focus is to promote the development of a technified agriculture and our portfolio's main specialty products seek to deliver the necessary nutrients in every drop of water to achieve a better performance and a superior quality. In addition, our potassium nitrate-based products help to reduce salinity accumulation, which eliminates the need for additional irrigation to remove salts from the soil.

How Potassium Nitrate can improve water use efficiency?

Improves the plant's water management:

Nitrate-fed plants utilize water twice as efficient as ammonium-fed plants.

Prevents water loss:

Potassium is responsible for opening and closing of stomata. Adequate potassium supply optimizes plant transpiration and reduces its water requirement.

Increases water uptake efficiency:

Adequate potassium nutrition of the plant enhances its water sourcing efficiency from the soil.

Prevents undesirable salinization of the root zone:

Application of potassium nitrate as main K-source eliminates the need for additional irrigation to remove undesirable salts from the root zone.
