Phosphate Uptake by Corn as Affected by Soil Characteristics and Root Morphology

Abstract: Phosphate uptake by plants growing in soil is influenced by the P uptake properties of the root and the P supply characteristics of the soil. This system may be described by mathematical simulation models. The objective of this research was to determine if a model used successfully for describing K uptake by corn (Zea mays L.) could be used for describing P uptake. A growth chamber experiment with corn grain on six soils varying widely in physical and chemical characteristics was conducted. Three harvests were… Show more

“…A morfologia do sistema radicular é determinada pelo comprimento, volume, superfície e raio das raízes e dos pelos radiculares (Schenk & Barber, 1979). A eficiência de absorção dos nutrientes varia na razão direta do comprimento e da finura das raízes porque esses atributos influenciam a superfície de absorção (Vilela & Anghinoni, 1984).…”
