Changes to spreading organic manure set to have ‘big impact’ on farm businesses says the CLA.

The Environment Agency has issued new guidance on the spreading of organic manure which is set to affect farmers and land managers in England.

Under Rule 1 of the Farming Rules for Water, in Spreading organic manures on agricultural land: RPS 252, farmers will have to justify why they need to apply organic manures in the autumn.

The biggest impact is set to be felt in the east of England where most pig and poultry manures are applied ahead of autumn cropping.

Responding to the new rule change, CLA’s Chief Land Use Policy Adviser Susan Twining said:

“It is good to see that the Environment Agency has taken on board industry concerns in this latest guidance, but it is still likely to have a big impact on many businesses, both practically and economically, with little time to adapt plans for this year.  

“Of course, water quality should never be compromised. A healthy water environment is key to ensuring wildlife can flourish, and everyone has their part to play.

“But further thought is urgently needed on how to balance the value of organic material for building soil health and benefits for carbon sequestration, reducing reliance on manufactured fertilisers, improving water holding capacity and associated flood risk.”

What do the new rules mean? 

• The Farming Rules for Water (FRfW) - Rule 1 has requirements for planning nutrient applications of organic material (livestock manures and slurries, digestate and biosolids) and manufactured fertiliser to crops, taking into account risks to water from nitrogen (N) and phosphorous (P).
• The Rules apply across the whole of England. Those in a Nitrate Vulnerable Zone (NVZ) should also follow the NVZ rules that have additional requirements. There should be proactive management of all crop nutrients on farm to avoid losses to water and also air (as ammonia and nitrous oxide).
• Mitigation action must be taken where there is a significant risk to water. This might include reviewing the need for organic material, adjustment of application rates, considering alternative fields, or the export of manures.
• Organic materials applied as a means of disposal, rather than as part of a crop nutrient management plan based on crop and soil needs, will be in breach of the Rules.
• The decision-making process on whether to apply organic material and/or manufactured fertiliser should be a transparent part of manure and nutrient management planning.
• A nutrient management plan should take account of crop need, manure type, its nitrogen (N) and phosphorus (P) content, rate of application, soil type and nutrient indices, and weather forecast at application.

The Reduction and Prevention of Agricultural Diffuse Pollution (England) Regulations were introduced in 2018 - known as the FRfW. These placed key aspects of the Code of Good Practice for water into regulation.
