Fertilizer recommendations based on soil-nitrogen levels - a total nutrient model

Tropical rice obtains a major portion of its N uptake from the soil as opposed to fertiliser nitrogen. Therefore N‐fertiliser recommendations should be based on the availability of soil nitrogen. This can be done by applying a total nutrient model, developed by Hildreth, which estimates yield as a f...
