Abstract
Nitrogen is necessary for plant growth and development. The global nitrogen utilisation efficiency for cereals and row crops is only 33%. Denitrification, volatilization, and leaching accounts for around 67 percent of fertiliser nitrogen loss. Due to field variations in soil nitrogen supply, varietal variability, and agro-climatic variables, nitrogenous fertiliser efficiency is limited. Large temporal and field-to-field variability inhibits the efficient use of nitrogenous fertilisers when broad-based general fertiliser recommendations are applied. Precision nutrient management for nitrogen application can be utilised to improve fertiliser efficiency while also lowering production costs. GreenSeeker is one of the most effective instruments for managing nitrogenous fertiliser inputs with precision, and it helps to avoid fertiliser overuse. It can be used to estimate the accurate amount of nitrogen to be applied at critical period of crop growth.
