Maize (Zea mays L.) growth and the rate of nutrient uptake are influenced by the length and radius of roots in the surface 20-cm of soil. In many soils a large share of the available P and K is in the upper 20-cm because of cycling from greater depths by the plant roots and application of P and K fertilizers, hence most P and K uptake comes from this layer.
