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). Crop requirements differ hugely between elements, from 100s kg/ha of N & K, 10s kg/ha P, S, & Ca, 100s g/ha Fe, Mn, Zn & Cu, to 1s g/ha B & Mo. Crops also differ inherently in these requirements due both to their genetics and their growing conditions. Crops need these nutrients primarily to form and operate the photosynthetic tissues that convert solar energy and water into edible (or otherwise useful) energy. Subsequently crops redistribute some nutrients from their leaves and stems to their generative organs, according to the nutritional requirements of crop re-establishment e.g. the nutrient needs of seedlings. Depending on which crop components are harvested and removed, crop nutrients are either exported and used in feeds or foods, or are returned to the soil to form soil organic matter.
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.
Farmers, advisors and researchers working together to understand and improve crop nutrition on-farm
Anglian Water is the largest water and water recycling company in England and Wales by geographic area. We supply water and water recycling services to almost seven million people in the East of England and Hartlepool.
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.
NRM’s GrainCheck service was launched in 2020 following several years of work with ADAS on the Yield Enhancement Network (YEN) project and to coincide with the RB209 recommendation for routine grain analysis. The test is suitable for cereals, oilseeds and pulses and should be interpreted alongside soil and tissue test results to give a full understanding of the effectiveness of crop nutrition programmes.
A forum for technical information about all aspects of fertilisers and crop nutrition.
YEN Nutrition brings together those wanting to achieve more precise crop nutrition. High fertiliser prices now make this vital. Assuming that 'crops know best' engagement in YEN Nutrition starts by benchmarking grain nutrients to show those that were limiting (or excessive) for each crop.
A range of products is available; these claim to enable more efficient nutrient uptake, so allow less nutrient to be used.
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.

Compost tea is water in which compost has been steeped under either aerobic or anaerobic conditions. Controversially, it is claimed to have beneficial effects when sprayed on crops, including enhanced growth and reduced pest and disease injury.
Soil N Supply is the nitrogen available to the crop from soil during the season. It is the most important component of estimating a crop's nitrogen requirement.
Nitrogen Use Efficiency is a widely used term increasingly discussed across industry and with farmers. However it can mean different things to different people.
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.

The intricate web of relationships between physical, chemical and biological soil components underpins crop and livestock health and productivity. Protecting soil health is also critical to environmental sustainability, as soils: • Exchange gases, such as carbon dioxide and nitrogen oxides, with the atmosphere • Regulate the flow of water and rainfall in the water cycle • Provide nutrients for plant growth, by breaking down organic matter and altering chemical fertilisers • Transform and store organic materials, as part of the terrestrial carbon cycle • Degrade contaminants applied through human activities or left by floods and aerial deposition A healthy soil is able to sustain, in the long term, these important functions. In a healthy soil, the interactions between chemistry (pH, nutrients and contaminants), physics (soil structure and water balance) and biology (including earthworms, microbes and plant roots) are optimised for the conditions in that place.

In February 2018, ADAS, AHDB and Defra launched the Grass and herbal leys farm network. The network is a partnership between farmers, researchers and industry and provides a platform to investigate the long term impacts of leys in rotations, such as: Quantifying changes in soil organic matter and soil health from introducing temporary grass/herbal leys across a range of soil types and rainfall areas. Quantifying subsequent changes to soil organic matter and soil health following the destruction of the temporary grass/herbal leys and return to arable production. Investigating the effectiveness of grass/herbal leys in controlling blackgrass in ‘problem’ fields.
Cover crops are grown primarily to ‘protect or improve’ soils between periods of regular crop production. They can be effective at improving soil functions by increasing soil nutrient and water retention, improving soil structure/quality, reducing the risk of soil erosion, surface run-off and diffuse pollution by providing soil cover and by managing weeds or soil-borne pests.
Organic materials, including livestock manures, biosolids, compost and digestate contain valuable plant nutrients which can save farmers money on their fertiliser bills, and organic matter which can help improve soil quality.
