Significance of root hairs at the field scale
Modelling root water and phosphorus uptake under different field conditions
Abstract
Root hairs play a significant role in phosphorus (P) extraction at the pore scale. However, their importance at the field scale remains poorly understood.
This study uses a continuum model to explore the impact of root hairs on the large-scale uptake of P, comparing root hair influence under different agricultural scenarios. High vs low and constant vs decaying P concentrations down the soil profile are considered, along with early vs late precipitation scenarios.
This is a publication arising from the Sustainable Crop production for International Development (SCPRID) programme.
