Increasing phosphate rock availability using a lupin green manure crop
(Lincoln University, 2004)
Legumes have been shown to increase the dissolution and utilisation of phosphate rock (PR) phosphorus (P) compared with non-legumes because of their acidifying effect on the rhizosphere. A promising agronomic approach for ...
Small-scale spatial variability of selected soil biological properties
A strategy for sampling soil from intact monolith lysimeters was established based on measurements of spatial heterogeneity within the lysimeter area. This was part of an ongoing study to determine relationships between ...
Seasonal fluctuations in phosphorus loss by leaching from a grassland soil
(Soil Science Society of America, 2004)
Phosphorus losses from soils have been reported to impair the water quality, resulting in deaths of fish and other marine animals, and can harm human health. The objective of this study was to determine the seasonal ...
