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).

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.

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.

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.

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.

A range of products are commercially available that claim to enable more efficient nutrient uptake, allowing less nutrient to be applied as fertiliser.

Iron is an important micronutrient for plant growth.  

Fertilisers, especially nitrogen, give some of the biggest environmental impacts of any inputs, from both their manufacture and their application.  A range of innovative approaches are being developed to reduce the energy costs, greenhouse gas emmissions and waste associated with the production of fertilisers.

Boron is an important micronutrient for plant growth.

Potassium is an important macro-nutrient for plant growth
