Effects of long-term grassland management on the chemical nature and bioavailability of soil phosphorus
(Springer-Verlag, 2012-07)
Relationships between the relative solubility of soil phosphorus (P) and short-term plant P uptake were investigated using soils obtained from a field trial that had been maintained under contrasting mowing regimen (no ...
Biochar and fertiliser applications influence phosphorus fractionation and wheat yield
(Springer Berlin Heidelberg, 2014-01)
The use of biochar in agriculture to achieve the dual benefits of improving soil quality whilst sequestering carbon (C) has received much attention. However, in low-intensity broadacre agricultural systems where yield is ...
Reduced root water uptake of summer maize grown in water-repellent soils simulated by HYDRUS-1D
(Elsevier, 2021-05)
Soil water repellency (SWR) is an ubiquitous soil property, that has major effects on surface and subsurface water flow, soil erosion, and therefore also affects plant growth and development. Soil water repellency has been ...
A review of the cost-effectiveness and suitability of mitigation strategies to prevent Phosphorus loss from dairy farms in New Zealand and Australia
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, Inc., 2012-05)
The loss of phosphorus (P) from land to water is detrimental to
surface water quality in many parts of New Zealand and Australia.
Farming, especially pasture-based dairying, can be a source of P
loss, but preventing it ...
Sixty years of seasonal irrigation affects carbon storage in soils beneath pasture grazed by sheep
(Elsevier BV, 2012-02-15)
For sixty years at Winchmore, South Island, New Zealand (43°48′S, 171°48′E, 160 masl), stoney soils under continuous pasture grazing by sheep have received rainfall (nil irrigation) or rainfall and irrigation as required ...
Fate of urine nitrogen through a volcanic vadose zone
(CSIRO, 2014)
© CSIRO 2014. To investigate the fate of nitrogen (N) from urine, dairy cow urine was amended with bromide (Br) and chloride (Cl), and applied onto a loamy sand soil with an underlying vadose zone of gritty coarse sands ...
Evidence of prehistoric wind erosion of the Mackenzie Basin, South Island, New Zealand: an assessment based on ¹³⁷Cs and Kawakawa-Oruanui tephra
(CSIRO Publishing, 2015-01-12)
Many authors have reported significant soil erosion resulting from the grazing of sheep, rabbit plagues and invasion of the exotic Hawkweed (Hieracium sp.) in the sub humid alpine region of Mackenzie Basin, South Island, ...
Metal bioavailability dynamics during a two-year trial using ryegrass (Lolium perenne L.) grown in soils treated with biosolids and metal salts
(CSIRO Publishing, 2012)
A 24-month field lysimeter experiment using ryegrass (Lolium perenne L.) grown in three soil types was used to investigate metal bioavailability dynamics following amendment with biosolids and metal salts (Cd, Cu, Ni, Zn). ...
Gradient differences in soil metal solubility and uptake by shoots and roots of wheat (T. aestivum)
(Springer Berlin Heidelberg, 2014-05)
The aim of this research was to identify and quantify gaps in currents methods and models for predicting the plant availability of selected nutrient and contaminant metals (Cu, Ni, Zn, Cd) in soil. This study investigated ...
Can the application of rare earth elements improve yield and decrease the uptake of cadmium in ryegrass-dominated pastures?
(CSIRO Publishing, 2015)
© 2015 CSIRO. Rare earth elements (REEs) have been linked to increases and decreases in plant growth and the uptake of biotoxic metals such as Cadmium (Cd). We hypothesised that under the right soil and climatic conditions ...
