New water rules have been announced for farmers that are expected to save them money and better protect the water environment.

Farmers will be expected to keep soil on the land, match nutrients to crop and soil needs and keep livestock fertilisers and manures out of the water.

Farmers and land managers will be able to determine what approach is best for their land, through methods such as deciding when it is safe to spread fertilisers.

The farming rules for water were drawn up with farming and environment stakeholders to recognise and build on progress that farmers have made in trying to tackle pollution. The new rules come into practice in England from April 2 2018.

There are eight rules, five about managing fertilisers and manures and three on managing soils.

The fertiliser rules require farmers to test their soils, then plan and apply their fertiliser or manure to improve soil nutrient levels and meet crop needs. They include minimum storage and spreading distances from water bodies. They also require the farmer to assess weather and soil conditions to reduce the risk of runoff and soil erosion.

The remaining rules require farmers to manage livestock by protecting land within five metres of water and reducing livestock poaching.

In addition to these rules, farmers are encouraged to incorporate organic fertilisers into the soil within 12 hours of spreading to significantly reduce ammonia pollution.

Environment minister Thérèse Coffey said: "These new rules are a win-win for farmers and the environment. They will help improve water quality, set a level playing field for all farmers, help businesses save money from better resource efficiency and improve their resilience.

"Our ambition is to be the first generation to leave the environment in a better state than we found it and these new rules will help us deliver our plans for a Green Brexit along with a better future for farming business."

The new rules are intended not only to benefit farming businesses as clean water helps tourism, fishing and shellfish businesses to thrive, reduces the cost of treatment and protects biodiversity.

The Environment Agency will roll out the rules through an advice led approach, working with farmers to meet the requirements before enforcement action is taken.
