Manure

Managing nutrients effectively is crucial for our soils, crops, livestock and environment. There are many resources and initiatives available to help. 

Key resources include:

 

RB209 Nutrient Management Guide

NFU Tried & Tested

Nitrate Vulnerable Zones

Farming Rules for Water

International Fertiliser Society has published many useful technical proceedings over the years

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).

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.     

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.

Farmers, advisors and researchers working together to understand and improve crop nutrition on-farm

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.

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

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.

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.

Share your ideas and experience of how to improve nutrient efficiency and reduce dependence on artificial fertilisers

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.  

GrassCheckGB is a grass monitoring project involving 50 dairy, beef and sheep farms.   Growth and quality data is published weekly throughout the growing season

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.

Mercury Environmental Systems Ltd. is a commercial organisation developing value-added applications from space-based data. The company’s core offering is the provision of data to aid farming, ecological and environmental decision-making, which is produced via a crop model that is constrained by satellite data. 

Boron is an important micronutrient for plant growth.

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.

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.
