Large amounts of potassium are commonly applied in turf maintenance, probably much more than are actually needed
Phosphate and potassium also contain embedded energy for their production as fertiliser. The table shows the calculated amounts.

centres contains significant quantities of nutrient, particularly phosphate derived from many domestic products. Industrial processes are now being installed to capture the phosphate, along with nitrogen, and process it to a fertiliser
A second area of concern is that some of the minerals mined and quarried for producing the nutrients in fertiliser are running out. This is particularly true for phosphate, where the rock phosphate in Morocco and other countries is becoming depleted; and therefore more expensive. There are resources in China, but very little is being exported. This phosphate is required for agricultural production and, indeed, there are major concerns that production could be limited through the lack of phosphate. It is an extremely serious issue.
Recycled products
Scientists and other practitioners have realised that the situation with regard to fertiliser for food crops needs to be addressed. A major focus of current research is the capturing of fertiliser nutrients in waste materials and re-using them as fertiliser. There is a considerable amount of work being carried out on this at present. For instance:
- Composted green and food waste contains N, P and K which can be re-applied. However, the concentrations tend to be rather small, and substantial quantities of compost would need to be applied to intensively managed turf
- Waste water in water treatment
- There is an increasing processing of food waste in the UK through anaerobic digestion. This is a biological process whereby methane gas is produced from the food waste material and, thereafter, used for energy production. However, most of the food waste is still present and requires disposal. It is normally split into a liquid and solid fraction. The liquid fraction contains some N, P and K, along with other nutrients such as sulphur, and it can be used as a fertiliser, although nutrient levels are low. The solid fraction can be composted
- By-products from industrial processes may produce nutrients. In turf management, ammonium sulphate is commonly used as an N source and most of this is derived from an industrial by-product. There are likely to be other materials with fertiliser value
- Greater interest is being taken in the ability of some plants to ‘fix’ atmospheric nitrogen. Clover is used to fix atmospheric N and is used within some turfgrass mixes. The possibility also exists to process leguminous crops such as peas or beans to produce a nitrogen fertiliser. As nitrogen fertiliser prices continue to increase, this may become an economically sound strategy for producing fertiliser
Most of these technologies are at an early stage and further developments will take place over the next few decades. However, because of increasing energy prices, the technologies used must have a low energy input. One way or another, the cost of
fertiliser will continue to increase and more recycled material will be used as fertiliser.
