“In a recent commercial field trial in Hollister, California, Nitricity partnered with an organic grower to evaluate whether Calcium-Fortified Ash Tea fertilizer could replace conventional in-season organic nitrogen inputs in cilantro, while maintaining, or even improving, crop performance. The results showed that it’s possible to grow more cilantro with significantly less nitrogen while improving key soil nutrient conditions that support long-term crop productivity. ”
