Impacts of phosphogypsum, soluble fertilizer and lime amendment of acid soils on the bioavailability of phosphorus and sulphur under lucerne (Medicago sativa)
Legumes play critical dual roles in grazed grassland ecosystems; providing nitrogen inputs and high-quality feed for grazing livestock. However, many species fail to persist in acidic, low fertility soils. A glasshouse ...
The relationship between soil moisture and soil water repellency persistence in hydrophobic soils
In this work, we modelled the response of soil water repellency (SWR) persistence to the decrease in moisture in drying soils, and we explored the implication of soil particle size distribution and specific surface area ...
Lime-induced pH elevation influences phosphorus biochemical processes and dynamics in the rhizosphere of Lupinus polyphyllus and Lupinus angustifolius
(Springer on behalf of Sociedad Chilena de la Ciencia del Suelo, 2021-05-05)
The biochemical drivers of phosphorus (P) availability and cycling are sensitive to changes in soil pH. However, reports of lime-induced pH modification effects on P availability are (1) inconsistent, (2) focused mainly ...
Surface runoff and losses of phosphorus from hydrophobic pastoral soils
The impact of soil water repellency (SWR) on soil phosphorus (P) mobility in surface water runoff remains contentious. Although SWR may cause a significant increase in surface runoff, especially in post-summer rainfall ...
Soil pH effects on phosphorus mobilization in the rhizosphere of Lupinus angustifolius.
(Springer Nature, 2021-10-14)
Purpose Increasing the pH of acid soils is a well-recognized means of improving their fertility; however, the effects that plants impose on rhizosphere soils in response to this change are not well understood. This research ...
Time series of remote sensing and water deficit to predict the occurrence of soil water repellency in New Zealand pastures
(Elsevier on behalf of International Society for Photogrammetry and Remote Sensing, 2020-11-01)
Soil water repellency (SWR) is a natural phenomenon occurring in soils throughout the world, which impacts upon ecosystem services at multiple temporal and spatial scales (nano to ecosystem scale). In pastures, the development ...
