Sylvinite

Sylvinite is a rock which occurs naturally in Britain and provides a high-quality potassium and sodium product, suitable for either straight or blended application. It is mined in the North Yorkshire Moors National Park and is crushed and sieved so that it can be easily handled and spread. Since October 1994 it has been included in the EC list of Authorised Fertilisers for Organic Production, for use where a need is recognized.

Potassium is an essential nutrient for plants and animals, and reserves in the soil must be maintained if crops and stock are not to be deprived. Produce which is sold off the farm contains significant levels of potash; for example grain and potatoes both contain about 6 kg of potash (K2O) per tonne of fresh weight, and beans perhaps twice that amount. A shortage of potassium in the soil will reduce the effectiveness of other nutrients and of natural soil processes, and will increase the risk of losses of nitrogen.

Sodium is essential to animals and to some plants. Fodder beet, mangels, sugar beet, spinach, carrots and celery all respond well to a dressing of sodium, many being originally maritime plants. There is also evidence that additional sodium applied to the soil will improve the taste of vegetables. Certainly sodium applied to grassland increases the palatabilily of grass to grazing ruminants, and it also helps to ensure that the animals are not deficient in sodium, by naturally raising the sodium content of the grass.

Sylvinite also contains important trace elements such as: boron, calcium, magnesium and iron. In fact Sylvinite meets all the requirements of today's farmer for a product that is agronomically balanced to increase yield. At the same time it gives manufacturers a high margin product.

Grading: Sylvinite is available in bulk with a grain-size analysis of 0-10 mm.
