Soil water extraction patterns of lucerne grown on stony soils
(Springer-Verlag on behalf of the Royal Netherlands Society of Agricultural Science, 2017-05)
Background and aims: Lucerne (Medicago sativa L.) is often grown under water-limited production conditions due to its capacity to extract water from deep soil layers through an extensive taproot system. These soils often ...
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 ...
Nitrification inhibition by common plants in New Zealand’s agricultural landscapes
(Lincoln University, 2013)
Nitrification, the production of nitrate by the bacterial oxidation of ammonium, is an important economic and environmental issue in New Zealand. Nitrification can lead to high levels of fertiliser nitrogen loss from soil ...
Amendment incorporation to increase soil water retention : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
(Lincoln University, 2018)
This thesis comprises two small core studies and two lysimeter studies, which are aimed at understanding how incorporation of soil amendments at cultivation can increase soil water retention in New Zealand’s shallow stony ...
Genome sequence of the clover symbiont Rhizobium leguminosarum bv. trifolii strain CC275e
(BMC ( part of Springer Nature), 2015-12-08)
Rhizobium leguminosarum bv. trifolii strain CC275e is a highly effective, N₂ fixing microsymbiont of white clover (Trifolium repens L.). The bacterium has been widely used in both Australia and New Zealand as a clover seed ...
A bioassay to compare the disease suppressive capacity of pasture soils
(New Zealand Plant Protection Society (Inc.), 2015)
© 2015 New Zealand Plant Protection Society (Inc.). Dynamic pathogen complexes can develop under pastures, thereby substantially reducing potential productivity. Suppression of such pathogen complexes is therefore of great ...
Likely controls on dissolved reactive phosphorus concentrations in baseflow of an agricultural stream
(Springer, 2020-05-06)
Purpose: High baseflow phosphorus (P) concentrations increase the likelihood of periphyton blooms. Several physical and chemical factors can control baseflow P concentrations such as hydraulic exchange with groundwater, ...
Effects of carbon substrate and irrigation on carbon dioxide emissions and denitrification for three grassland soils : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
(Lincoln University, 2019)
Conversion of non irrigated grassland to high−intensity farm systems with irrigation is a major land−use change to enable a higher yield year−round in New Zealand. Research is needed to better understand the links between ...
Comparative genotoxicity of cadmium and lead in earthworm coelomocytes
(Hindawi Publishing Corporation, 2011)
To determine genotoxicity to coelomocytes, Pheretima peguana earthworms were exposed in filter paper studies to cadmium (Cd) and lead (Pb) for 48 h, at concentrations less than the LC₁₀—Cd: 0.09, 0.19, 0.38, 0.75, and 1.50 ...
Soil microbial communities influencing organic phosphorus mineralization in a coastal dune chronosequence in New Zealand
(Oxford University Press on behalf of FEMS, 2021-04)
The Haast chronosequence in New Zealand is an ∼6500-year dune formation series, characterized by rapid podzol development, phosphorus (P) depletion and a decline in aboveground biomass. We examined bacterial and fungal ...
