Effects of Phosphorus on Nitrification Process in a Fertile Soil Amended with Urea

open access: yesAgriculture, 2021
While the effects of carbon on soil nitrogen (N) cycle have been extensively studied, it is not clearly understood how co-existing macronutrients, such as phosphorus (P), affect the N cycle in agroecosystems.
