Sodium Nitrate as an Input for Use in Organic Crop Production
Natural Sodium Nitrate, a.k.a. Chilean Nitrate- OMRI listed (15-0-2) is available in a dry, flowable prill form that is also 100% water-soluble. It is marketed by the Chilean producer, SQM, under the brand name: Allganic™ Nitrogen Plus 15-0-2.
Sodium Nitrate is an organic nitrate nitrogen nutrient source, sustainably derived from natural rock deposits found in the Atacama Desert in Chile. The best practice as a grower is to maximize the effect of a small amount by applying it when temperatures are low and soils do not have the ability to produce readily available nitrate-nitrogen.
