Spreading K at this time of the year is often the most efficient method of application as it will be best used. If K is applied in spring there is a danger of it not getting into the soil before it is taken up by grazing animals. Approximately 60pc of our soils nationally are at index 1 and 2 for potassium. This means that six out of 10 silage fields are deficient in potassium, and this poses a challenge. So why is potassium such an important fertiliser? Potassium is the nutrient taken up in the greatest quantity by grassland swards and has a wide-ranging role in the plant, affecting nutrient uptake, photosynthesis, rate of growth and feed value. It is particularly important for increasing stem strength, improving drought resistance and cold tolerance, and importantly for increasing yield. Potassium fertilisation is vital, especially in autumn and on older grass. If adequate amounts of potassium are not available, the rate of growth and yield will be restricted.

Try to spread muriate of potash (0-0-50) during a dry spell if you can, during October if your K index is low (Index 1 or 2). One bag/acre of 0:0:50 applied will generally result in the soil rising an index, i.e., moving from index 2 to index 3.

*Reminder* Drummonds can carry out soil tests on your farm, advise you best based on results and help correct your soil pH and P&k.
