Extract

The effects of soil temperature, light intensity, soil-water tension and amount and form of N, on cation-anion relationships in Italian rye-grass were tested by growing grass in a clay loam in three experiments under glass. The grass had six levels of NO3-N or NH4-N with a uniform dressing of P, S, K, Ca and Mg; NH4-N was treated with 'NServe' to prevent nitrification. In the first experiment the grass was grown at 11°, 19-5° and 28° C, in the second in 100, 68 and 44% glasshouse ' daylight', and in the third at three soil-water tensions. Yields were greatest at 19-5° C, 100% glasshouse
