SQM's specialty products contribute to a high efficiency in the use of water. A correct crop nutrition allows the plant to absorb nutrients in an adequate way and thus, to use a minimum amount of the water required. Our focus is to promote the development of a technified agriculture and our portfolio's main specialty products seek to deliver in every drop of water, all that is necessary to achieve a higher 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. We contribute to a sustainable agriculture over time, generating stronger and healthier crops that deliver maximum yields through a lower use of resources.

How Potassium Nitrate can improved 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.
