Nitrate retention under sugarcane in wet tropical Queensland deep soil profiles

Rasiah, V; Armour, J; Menzies, N W; Donn, M J; Mahendrarajah, S; Heiner, D A


Nitrate leaching below the crop root-zone in variable charge soils may be adsorbed at anion exchange sites, thereby temporarily reducing the risk of contamination of water bodies. The objectives of this study were (i) to investigate whether nitrate adsorption, accumulation, and retention in the Johnstone River Catchment of Far North Queensland wet tropics is widespread; (ii) to assess the capacity of soil in the Johnstone River Catchment to retain nitrate; and (iii) to deduce the consequences...[Show more]
