2019's Bumper grass yields means nutrient replenishment and fertiliser planning is essential


Phosphorus, Potassium and Sulphur could have been significantly depleted in recent months so soil testing and an appropriate fertiliser management strategy is now needed to ensure levels are restored effectively. In intensive grassland systems you really have to test each field for P, K, Mg and pH at least every 3 years, but there is a strong case for testing more this year, particularly on fields that were borderline on the targets of pH 6.5, and indexes of 2 and 2- for P and K respectively. 



Sulphur is also likely to have been removed from the system in a significant quantity this year and this will also need addressing. Sulphur is a major component of the protein-forming amino acids and is essential when higher amounts of Nitrogen are applied. Levels have to be kept proportional to the amount of Nitrogen used and, with reduced atmospheric levels of Sulphur, applications have to be made throughout the season to keep supply adequate for optimum Nitrogen utilisation and crude protein production.

“The simplest way to address the nutrient shortfall and ensure they are delivered in the best way possible to growing swards is to use NPKS true granular compounds. These type of products, alongside slurries and manures, are the ideal way to restore nutrient levels in high production systems or in years where off-take of grass has been substantial.''

 All CF compounds are British-made true and based on Ammonium Nitrate (AN) which has been proven over many years to be the most effective source of N for grassland production systems.” For example, MultiCut Sulphur (23-4-13 + 7SO3) is an ideal high Nitrogen/high potash product for use all season for a system of multiple cuts of grass silage or consider SingleTop (27N + 12SO3) which provides a balanced supply of P and K.
