Nitrogen recommendations take account of NVZ Action Programme rules and Nmax. Careful planning that maximises the efficient use of fertiliser and organic materials can help reduce the amount of N that is lost as nitrous oxide, a greenhouse gas. Read Technical Note (TN): Nitrogen Recommendations for Cereals, Oilseed Rape and Potatoes.   Cereals such as maize, rice, wheat and sorghum are the most important crops for human nutrition. Like other plants, cereals associate with diverse bacteria (including nitrogen-fixing bacteria. A model was developed which estimates the mineral nitrogen content of the soil throughout the year by simulating mineralization and immobilization of N, removal of N from soil by crop uptake, denitrification, leaching or volatilization of ammonia from the soil surface or the senescing plant. The model was tested for its ability to simulate the fate of a pulse of 15N labelled fertilizer through Cited by: 3. As wheat is one of the major agricultural crops in Europe (Table 1), its fertilizer requirements have been investigated intensively during the last decades (Scharpf and Wehrmann, ; Hanus, ;.

Cereal Production documents the proceedings of the Second International Summer School in Agriculture held by the Royal Dublin Society in July This book relates individual disciplines to the central concept in cereal production, which is the optimization of yield and quality and maximization of net return. RB stands for Reference Book All cereals – phosphate, potash, magnesium and sulphur 23 All cereals – micronutrients 25 The revised recommendations allow the crop nitrogen requirement to be adjusted for expected yield for winter wheat, winter barley and spring barley. Finally, a major requirement that cuts across all the five cereals is the need to strengthen the capacity of the National Agricultural Research Systems (NARS) in African countries. Table 2 presents a summary of budgetary requirements for the work proposed for sorghum / millets, maize, wheat and rice in short, medium and long term basis. Get this from a library!

Two new AHDB research projects on nitrogen (N) and sulphur (S) management in oats and wheat have been bolstered by a half a million pound co-investment from industry UK Partnership for Crop Nutrition AHDB updates the Nutrient Management Guide (RB) in partnership with a number of organisations. 2. The Use of Nitrogen in Cereals. The use of N in plants involves a number of phases, mainly N uptake, reduction, assimilation, translocation, and remobilization [].Nitrogen use efficiency in cereals is defined as the grain yield per unit of N available in the soil [].Cereal NUE is the result between plant uptake efficiency (NUpE) and the utilization efficiency (NUtE), and therefore the.   The widespread use of nitrogen (N) fertilizers has been one of the major factors in ensuring global food security (Erisman et al. ) because soils normally cannot meet N requirement of high yielding varieties of cereals.
