High K is a quality fertiliser which is ideal for areas requiring a large amount of potassium (K). It also benefits from a low amount of nitrogen, magnesium & Iron. Although this product is mainly used in paddocks & pasture, it is also suitable for lawns, sports turf & amenity areas, this is due to its compound mini-granule formulation.

This product can be used at higher rates for correcting potassium deficiencies, or used as a general feed which will slowly release the fertiliser over a 6 week period. 

The application rate will depend on how many times you will apply the product, and also what the grass is going to be used for. If you require a detailed reccomendation, please contact us for a soil analysis kit. Apply either by hand or through one of our applicators.

*Please note, free delivery is only offered on fertiliser orders over £300 (ex VAT)*

Understanding Fertiliser Analysis

Under the metric system the unit of measurement is a kg

Recommendations are given in kg/ha

A fertiliser with the analysis 5:0:29:4Fe:2.5Mg contains:-

5% Nitrogen 0% Phosphate 28% Potassium 4% Iron(Fe) 2.5% Magnesium

So in a 25kg bag:-

5% of the 25kg is Nitrogen i.e. 1.25kg N

0% of the 25kg is Phosphate i.e. 0kg P

29% of the 25kg is Potassium i.e. 7kg K

4% of the 25kg is Iron i.e. 1kg Fe

2.5% of the 25kg is Magnesium i.e. 0.75%
