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 ...
Increased lucerne nodulation in acid soils with Sinorhizobium meliloti and lucerne tolerant to low pH and high aluminium
(CSIRO Publishing, 2018-10)
Acidic conditions with damaging levels of available aluminium (Al3+) currently limit lucerne (Medicago sativa) production on soils in the New Zealand high country and in large areas of Australia. Increased lucerne nodulation ...
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 ...
Drought resistance of Trifolium repens × Trifolium uniflorum interspecific hybrids
(CSIRO Publishing, 2014)
© 2014 CSIRO. White clover (Trifolium repens L.) is a widely used and highly valued temperate legume; however, its productivity and survival are restricted under dryland and drought conditions. 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 ...
Effect of urine, potassium and dicyandiamide application on pasture production from a free-draining Canterbury dairy pasture soil
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2014)
A cut-and-carry trial was conducted on a low quick-test potassium (QTK ≤ 4) Lismore soil during 2012-13 in Springston, Canterbury to test the responsiveness of a dairy pasture to urine, dicyandiamide (DCD) and potassium ...
Dry matter accumulation and nutritive value of winter forage crops sown in Canterbury on different dates
(Taylor & Francis on behalf of The Royal Society of New Zealand, 2013)
Supplementary forage crops are used in New Zealand to overcome feed shortages during winter and early spring. The objective of this study was to maximize annual dry matter (DM) yield by optimizing sowing and harvest dates. ...
Fate of phosphorus applied to soil in pig slurry under cropping in southern Brazil
(Elsevier, 2018-07-01)
Strongly weathered soils (such as Oxisols), are inherently phosphorus (P) limiting and highly P-sorptive thus requiring continued P inputs for productive agriculture. Constant P inputs result in accumulation of soil P with ...
