Environmental parameters affecting the concentration of iodine in New Zealand pasture
(American Society of Agronomy, Crop Science Society of America & Soil Science of America, 2019-08-21)
Iodine (I) is an essential trace element commonly deficient in agricultural systems. Whereas there is much information on I in food crops, there is a lacuna of knowledge on the environmental factors that affect pasture I ...
Nitrous oxide fluxes, soil oxygen, and denitrification potential of urine- and non-urine-treated soil under different irrigation frequencies

Phosphorus leaching from an organic and a mineral arable soil in a rainfall simulation study
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2018-05-03)
Phosphorus derived from agricultural systems has been found to cause eutrophication of surface waters. To combat this, the specific location of soil profile P release is necessary for development of effective mitigation ...
Effects of lime and organic amendments derived from varied source materials on cadmium uptake by potato
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, Inc., 2017-07)
Repeated applications of Cd-rich phosphate fertilizers have resulted in elevated concentrations of this toxic element in some New Zealand soils. Exceedance of the food safety standard for Cd (0.1 mg kg⁻¹ fresh weight) has ...
Potential use of biosolids to reforest degraded areas with New Zealand native vegetation
(Crop Science Society of America with Soil Science Society of America and American Society of Agronomy, 2017-06-30)
Biosolids could potentially be used for reforestation of degraded soils in New Zealand with native vegetation. Many native plant species of New Zealand thrive in low-fertility soils, and there is scant knowledge about their ...
Irrigation effects on soil organic carbon under a ryegrass-white clover pasture on a Lismore stony silt loam soil : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
(Lincoln University, 2020)
Long-term summer irrigation of temperate managed pastures has been reported to either increase or decrease soil organic carbon (SOC) stocks when compared with dryland systems. Understanding the short-term effects of ...
