Liquid nitrogen fertilization on the yield and phenologic variables of narrow-row cotton

Bioscience Journal, 2020
Slow-release liquid nitrogen fertilizer sources have been around since 1970. However, this technique is not widely used in the field, probably due to the low cost per ton of nitrogen in the solid form.
