A quantitative analysis of the factors affecting plant nutrient uptake from some soils
Journal of Soil Science 26(3): 195-206
A model of solute uptake by a growing root system is discussed in relation to the ability of a soil to support the nutritional requirements of plants. It is quantitative, and should apply to the absorption of nitrate, phosphate, and potassium by grasses and arable crops. The principles, if not the detail, are relevant to all soils.The model was tested in an experiment in which the nitrogen and potassium taken up by rape plant were measured.
