calculate dissolved nutrient concentration

If you’re dissolving a fertilizer nutrient for fertigation, whether through an injector or from a tank, use the form below to determine your mixing ratio. Keep in mind that if you’re using sodium nitrate (a.k.a. Chilean nitrate), it contains¬†28% sodium, which can damage foliage if too high a concentration is used. Contact with foliage should be avoided.

This form does not apply to insoluble or granular materials.
