Fertilizer Nitrogen Management
1989ABSTRACT Nitrogen fertilizer supply is the primary nutrient limitation for both total world food supply and protein content. Unfortunately N fertilizer can also be a major contributor of N to ground water supplies if managed improperly. “Proper use” of N fertilizer involves accurate assessment of need before application.

Nitrogen is the one of most limiting nutrient for rice production, and in India rice cultivation alone accounts approximately 37% of the total fertilizer-N consumption in the year 1917-18. However, 60-70% of applied N is lost from the rice ecosystem system in the form of reactive N species such as ammonia (NH3), nitrous oxide (N2O), nitric oxide (NO ...

Nitrogen Responses and Nitrogen Management in Potato
Potato Research, 2009Innumerable experiments have been carried out to establish the yield response of potato to the rate of nitrogen (N) supply. Given the continuing change in production level of potato and because of the need to maximise the nutrient use efficiency and to reduce losses of harmful nitrogenous compounds to the environment, such research is still necessary ...

Journal of Vegetable Crop Production, 2004
ABSTRACT Management of nitrogen (N) fertilization, in terms of rate, timing, and method of application, influence the yield and quality of potatoes. Optimal management of N and irrigation is important to improve N uptake efficiency, and minimize N losses while maintaining high yields and quality.

Nitrogen balances can help fine‐tune nitrogen management
Crops & Soils, 2018This article presents a framework for using nitrogen use efficiency within the context of yield and crop quality goals to evaluate fertilizer management. The framework's goal is to diagnose underlying factors contributing to the inefficient use of fertilizer.

Sensor Based Nitrogen Management Reduced Nitrogen and Maintained Yield
Crop Management, 2011Nitrogen fertilizer needs vary from year to year and field to field leaving small grain producer's continuously seeking new techniques to improve their fertilizer use efficiency and reduce input costs. This study evaluated the use of the Sensor Based Nitrogen Rate Calculator (SBNRC) on large‐scale producer fields to generate N recommendations for ...

Rhizobium Management and Nitrogen Fixation
2007Through fixing their own nitrogen, growing lentils offers a substantial saving in the need to use fossil fuels to generate fixed nitrogen for agricultural production. Much of the nitrogen fixed by the lentil crop may then be available for subsequent crops in the rotation as crop residues break down.
