Granular Potash – NitroFert
Potassium (K) is an essential element for plants as it improves water uptake, carbohydrate storage and frost and disease resistance. It also strengthens the standing power of cereals reducing the risk of lodging and counteracts the damaging effects of excessive nitrogen. Barley is probably the most susceptible cereal to potassium deficiency. In horticulture, potassium improves the eating quality of fruit and vegetables. In grassland situations, it increases the amount of clover and autumn application of K will help to minimise problems with grass tetany in cows.
NitroFert supply two types of potassium fertiliser as listed below.
The amount of K to be applied depends on
- The level of K in the soil.
- The crop to be fertilised. Sugar beet, potatoes and onions are crops most responsive to it.
- The level of K already supplied in slurry.
