| Question: | "As you know, we have a recently constructed soccer pitch consisting of sand over a complete drainage carpet. We appreciated that pitches of this kind are subject to the very rapid leaching of nutrients and we are wondering whether slow release nitrogen fertilisers would be more appropriate than conventional products in such situations." |

| Answer/Response: | "Sand pitches certainly need more nitrogen at more frequent intervals than conventional soil pitches if good grass is to be maintained. One of the problems with conventional fertilisers is that one obtains only a short-lived and rapid flush of growth before nutrients wash through the profile. Newer slow release products certainly have a use in such situations, a disadvantage being the fact that they are relatively expensive. For a sand pitch under average circumstances, it is probable that some 225 kg/ha/year of nitrogen should be given. Theoretically, it should be possible to give an application of slow release fertiliser in the spring which would give sustained growth throughout the growing period. Under British climatic conditions, however, this almost never occurs and it is usually necessary to give at least two dressings to maintain sufficient growth. The most commonly used slow release fertiliser is based on IBDU and contains 32% nitrogen. The nitrogen in the fertiliser is broken down by soil micro-organisms to soluble urea and then to ammonium and nitrate. The speed of this process depends on soil temperature and moisture- the higher the temperature and moisture content, then the faster the process takes place. The duration of the effect of the fertiliser will therefore depend on the climate during a particular summer. In the case of sand pitches, there is likely to be less bacterial activity than there would be in a soil with higher organic matter content and this may also be a factor in slowing down the rate at which the fertiliser provides plant nutrients. Such fertiliser can also release small quantities of nutrients in the winter when the temperature is about 10°C and bacterial action still taking place. This is an advantage in maintaining a good grass cover in the playing period. Alternative materials are available in the form of CDU fertiliser which tests at Bingley have shown to produce an excessive flush of growth following spring applications, although there is also a definite carry-over effect from the previous autumn. Ureaform is another material which may produce excessive growth after initial application. Resin coated fertilisers are a recent introduction and may also contain phosphate and potash, giving slow release of all three essential nutrients. The product can be criticised because large granules tend to remain on the surface and may be picked up by mowers. Mowing may also cause problems with a sulphur coated urea fertilisers with fertiliser materials are coated in sulphur which may be damaged by mower blades, so causing excessively fast release. Fertilisers are also available which contain nitrification inhibitors which slow down the process of bacterial action, giving nutrient release over a longer period in consequence. These last named products have only become available recently in Britain and little experience has been gained in their use. In summary, slow release fertilisers have a place in turf maintenance in this country, particularly in very sandy constructions where rapid nutrient leaching is a problem." |
