Evaluate the benefits of lignite in improving nutrient use efficiency for NPK in sugarcane
There has been a lot of research conducted in the horticultural sector with lignite to assist with the stabilization of nitrogen, as well as phosphorus and potassium in the soil profile, improving plant uptake and NUE.
Due to the nature of the amount of biomass produced by a sugarcane crop, the nutrient requirements for the whole crop is placed subsurface in a single pass, which has the potential for a quantity of nutrients to be lost to the environment through leaching or as a gas.
