Product Description

At Greenland Seeds we are proud to be stockists of Suregrow CSM – The UK’s finest NATURAL equine grass fertilizer. Specifically designed for horse paddocks to aid grass growth and horse health.

CSM is without doubt a top quality horse and pony paddock fertilizer which provides pastures with a wide range of minerals and trace elements. These minerals maximise the utilisation of Nitrogen, Phosphate, Potash and Sulphur. By improving the mineral and trace element content in your paddock you will ultimately contribute to horse health.

CSM contains over 70 minerals and trace elements including calcified seaweed. The calcified seaweed (rich in Iron, Manganese, Cobalt, Zinc, Iodine, Selenium, Molybdenum) in the CSM granules slowly release the minerals and trace elements and reduce soil acidity thus increasing the palatability of the grass for horses. Calcified seaweed in itself has been proven by grassland farmers to transform the nutrient status of the grass and soil.

CSM encourages root development and acts as a soil conditioner which results in a denser more vibrant turf. 

Works well with our special equine grass seed (and herb) mixes: Equine Overseeding Paddock Grass Seed Mix, Horse and Pony Paddock Grass Seed Mix, Natural Meadow & Laminitics; and our Special Equine Herbal Paddock Grass Seed Mix.

What is in this Fertiliser?

Application Rate:

To be sown approx 2 bags per acre. (NB Application rate is the same year-round).

CSM can be applied all year round but for optimum results and impact we recommend the continuous use of CSM ideally twice per year in late Spring and again in early Autumn, this will ensure a continuous supply of minerals and trace elements. As this is a natural product there is no need to remove horses during application as long as grass length is at 2 inches minimum.

Can be spread by hand.
