The efficacy of good practice to prevent long-term leaching losses of phosphorus from an irrigated dairy farm
(Elsevier, 2019-03-01)
Phosphorus (P) can be leached from intensive land uses, including grazed dairy farming. There is some evidence to suggest that P-leaching can enrich groundwater, especially where fertiliser or farm dairy effluent P (FDE) ...
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 ...
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 ...
Assessment of the accuracy of profile available water and potential rooting depth estimates held within New Zealand's fundamental soil layers geo-database
(CSIRO Publishing, 2015)
© 2015 CSIRO. The Fundamental Soil Layers (FSL) serve historically as New Zealand's primary source of soil information. They contain a range of New Zealand's soil attribute information held in a spatial database. Despite ...
Pathways of soil genesis in the Coast Range of Oregon, USA
(Springer Netherlands on behalf of the Royal Netherlands Society of Agricultural Science, 2013-06)
Background and Aims: Soil chronosequences on marine terraces along the Pacific Coast of California and Oregon show evidence of podzolization, though soils ultimately evolve to Ultisols. It is not clear if this pathway of ...
Soil profile inversion in earthquake-induced liquefaction-affected soils and the potential effects on urban trees
(Elsevier B.V., 2014-01)
A sequence of three large earthquakes in 2012/2011 caused liquefaction ground damage to over a third of Christchurch, New Zealand. This paper presents results of a characterisation of liquefaction-affected soil (LAS) and, ...
