Chilean Nitrate Fertilizer


Chilean Nitrate Fertilizer provides a non-synthetic, natural source of nitrogen for your vegetable garden. Also known as sodium nitrate, this fertilizer is bagged in a dry, flowable form that is 100% water soluble. OMRI listed for organic use.


Chilean Nitrate fertilizer is an organic nitrate nitrogen nutrient source collected from natural rock deposits found in the Atacama Desert in Chile, where it has been used by organic farmers for over 100 years. Also known as sodium nitrate, Chilean Nitrate is a natural, non-synthetic nitrogen source that contains many essential micro-nutrients, such as iodine and selenium, that cannot be found in conventional, synthetically-produced nitrogen fertilizers.

Chilean Nitrate fertilizer improves the nutritional quality of crops by increasing protein, albumine, amino acids, vitamin B, carotin and micro-elements content. It is 100% water soluble and may be applied in the dry or liquid form. Use it to side-dress crops in the dry form, or dissolve in water and use in our Hoss Fertilizer Injector to administer the liquid form.

An excellent nitrate nitrogen source for corn early in the growing season (4-7th leaf), as university research has shown improved corn yields and quality. Chilean Nitrate also increases early harvest yields for many early season cole crops including broccoli, cauliflower, and cabbage.

Chilean Nitrate Fertilizer Application

For side-dressing field corn, popcorn or sweet corn, apply 3.5 lbs per 1,000 square feet at least 2-3 times throughout the life of the plant. We recommend an initial application prior to the first hilling of the corn. Apply the granular fertilizer alongside the row and cover with soil during the hilling process.

For other vegetable crops, apply alongside the plants at a rate of 1 cup per 10 feet. Use a hoe or other hand cultivation tool to mix the fertilizer into the soil. Apply every 2-3 weeks or as needed.

This was my 2nd bag of Chilean Nitrate. It was a huge success on my early corn (Silver King from Hoss) so I wanted to have some for my second planting of Jimmy Red. I have really bad soil that I have been trying to compost and improve it bit by bit. I'm convinced the Chilean Nitrate made the difference in my Silver King which was not only delicious but beautiful and perfect ears!
