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.
Potash Development Association (PDA) is an independent organisation, formed in 1984, to provide technical information and advice in the UK and Ireland. It is supported by ICL UK Sales & Cleveland Potash Ltd who supply the fertiliser market with potash products.
Review conducted by ADAS and funded by AHDB into how farmers should respond to the high fertiliser (& grain) prices experienced in 2022.
The flour milling industry plays a vital role in feeding and nourishing the nation – flour is an ingredient in 30% of supermarket foods. UK Flour Millers is proud of the part it plays in ensuring the industry continues to operate efficiently and reliably so that everyone can enjoy their daily bread.
Leading arable event The CropTec Show is returning to the East of England Showground in Peterborough on November 23 and 24. Now in its 10th year, the event will deliver the well-loved CropTec formula combining industry-leading exhibitors, the latest machinery and technology, networking and discussion opportunities as well as valuable updates on developments across the arable sector. Tickets are free and available now by registering at www.croptecshow.com.
A range of products are commercially available that claim to enable more efficient nutrient uptake, allowing less nutrient to be applied as fertiliser.

Frontier Agriculture is the UK's leading crop production and grain marketing business, recognised for its close customer relationships with farmers and grain consumers and its successful management of the arable supply chain.
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.
Sulphur is an essential nutrient required for protein formation and a number of enzyme reactions within plant cells which are required for satisfactory crop growth.

The study measured the N available after spring-sown peas, field beans or autumn sown cereals in eastern England and the subsequent response of winter wheat to fertiliser nitrogen.
Scientists are working to understand how plants engage with soil microorganisms, so we can reactivate them.
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.
