The problem is increasing, because the average application of potash fertilisers to grassland has. Potash and phosphate are both used to produce fertilizers, which are becoming increasingly important as demand for food grows. However, potash and phosphate have different roles in crop growth.

Discusses the need for phosphate and potash, management, types of fertilizer and tabulates the amounts of phosphate and potash requirements for grassland establishment, grazing only, cut crops, herbage seed crops, legumes, grass for hay.

Brockman, P. Shaw, K. WoltonCited by: Manures contain valuable levels of phosphate and potash; cattle slurry and FYM should provide P and K in the ideal ratio required for grass for silage or hay.

A manure management strategy should in the first place use manures on crops and on grass for conservation, rather than on grazed grass, which already receives nutrient returns from the. Phosphate and potash fertilising of grassland is quite well understood. In a grazing situation there is frequently no need to apply any because of the frequent returns of dung and urine.

Only in deficient soils will any response be observed. In the case of potash there is an important connection with the incidence of hypomagnesaemia or grass.

Phosphate, Potash and magnesium for field crops (Section 8 contains additional information for grassland) Phosphate, potash and magnesium applied in fertilisers and manures move only slowly through the soil and many soils can hold large quantities of these nutrients in forms that are readily available for crop uptake over several years.

Phosphate and potash. The general principles of using phosphate, potash and magnesium fertilisers are described in Section 1. As described above for nitrogen, the recycling of phosphate and potash through conserved grass and back to silage fields in manure applications will commonly result in sufficient nutrients to maintain soil P and K Indices.
