Fertiliser Advice

Fertiliser advice is aimed at producing optimum crop yields on an annual basis while protecting the environment as well as maximising return on investment for the farmer.

The Major and Micro Nutrient Advice For Productive Agricultural Crops known as the Green Book provides nutrient advice for a wide range of crops grown under Irish conditions. Nutrient advice starts with taking soil samples to provide a basis for building an effective fertiliser programme. The Green book provides details on taking soil samples to ensure reliable results. Nutrient advice is presented for all major grassland, cereal, root, vegetable and fruit crops.

The 5th Edition of the Green Book, published in June 2020, is available to guide fertiliser advice.
