Nitrogen is required annually by most crops (except pulses) to achieve yield and quality. Judging how much N to apply is a key part of nutrient management.

Nitrogen Use Efficiency is a widely used term increasingly discussed across industry and between farmers. However it can mean different things to different people, and is best defined with care.

Plants need around 12 essential mineral nutrients to grow: Nitrogen (N), Phosphorous (P), Potassium (K), Magnesium (Mg), Sulphur (S), Calcium (Ca), Iron (Fe), Manganese (Mn), Zinc (Zn), Copper (Cu), Boron (B) and Molybdenum (Mo).

ADAS are planning a Nutrition Challenge to compare the effect of different nutrition programmes on winter feed wheat yield, N uptake and gross margin, in the 2022/23 season. This is particularly timely following the recent dramatic rise in nitrogen fertiliser prices, which has forced the industry to re-examine nutrition strategies. Objectives of the project are to showcase good nutrition products and practices so that farmers are equipped and encouraged to use fertiliser better, for the benefit of the environment and their own gross margins.

Phosphorus (P) is an essential nutrient for both plants and animals, playing a key role in energy transfer as a major component of ATP. It is also vital in DNA. For full capture & conversion of solar energy, crop canopies need 30-40 kg/ha P. Crop species redistribute most of this P (~85%; more than for any other nutrient) to their seeds during canopy senescence, where it is stored as phytate. Plants appear to do this because, until their roots proliferate, plant seedlings are highly sensitive to P shortages.

Accounting for fertiliser and feed prices, it calculates the cost benefit of applying nitrogen to grassland. Use this tool to work out the cost versus the benefit of applying nitrogen fertiliser to grassland. Accounting for fertiliser and feed prices, it calculates the cost of nitrogen application and then compares with the feed value of grass. This will help with the decision on whether it is more cost effective to apply nitrogen fertiliser to grassland or purchase feed instead.
