“…Leaching of nutrients from growing and senescent leaves has been demonstrated by several workers (Tukey, 1970) although the method used in many studies has been to immerse leaves in water. Page, Smalley & Talibudeen (1978) attributed all the losses of potassium and calcium from senescing winter wheat to leaching by heavy rain showers and Raybould (1976), working in the crop of wheat reported in this paper, showed that concentrations of sulphate and potassium in rainwater were increased after passing through the canopy. However, no rain fell during the period of rapid potassium loss nor during the initial loss of sulphur, and using the data presented by Raybould, Unsworth & Gregory (1977), the maximum loss of sulphur in the post-anthesis period by leaching by rain would be 0-25 g/m 2 compared with the measured crop loss of 1 g/m 2 .…”

SUMMARYMaris Huntsman winter wheat was sown on 30 October 1974 and grown under typical farming conditions. Between sowing and harvest (5 August 1975), the crop was sampled on 23 occasions and dried samples of individual plant components were analysed for Na, K, Ca, Mg, P, S and N composition.The concentration of nutrients within the whole plant generally decreased throughout growth but different parts of the plant varied in their behaviour. Uptake of all nutrients ceased at, or shortly after, anthesis in mid-June while dry-matter accumulation continued slowly for a further 2–3 weeks and almost stopped 4 weeks before harvest. The major period of nutrient uptake occurred between mid-April and mid June coincident with the period of rapid shoot growth. Large amounts of potassium and sulphur (almost 50% of the plant's anthesis content) and lesser amounts of calcium (15%) were lost from the plant after anthesis and efflux from the roots into the soil appeared to be the most likely pathway of removal.Accumulation of nutrients in the ear occurred throughout grain-filling by translocation from other parts of the plant, particularly the leaves and stems: the effects of this redistribution on the production of dry matter after anthesis are discussed.

“…As the plants were grown in a greenhouse without exposure to rainfall, the losses may be not due to leaching from the leaf blade, which often occurs outdoors (PAGE et al 1978). We suspect that these losses may be associated with the release of K and N from the roots to the soil.…”

“…Thorup-Kristensen, 1993a) for vegetable crops that depend on early N uptake. This is not the case for wheat, which continues to absorb high amounts of N late in the growing season (Page et al, 1978;Barraclough, 1986;Fowler, 2003). As regards to cover crops, phacelia proved to be less reliable than the other species in terms of N uptake.…”
