Application of a physically based soil erosion model, GUEST, in the absence of data on runoff rates I. Theory and methodology.
January 1, 1999... Abstract When physically based erosion models such as GUEST are used to determine soil erodibility parameters or to predict the rate of soil loss, data on runoff rates, as distinct from event runoff amount, are often needed. Data on runoff...

Application of a physically based soil erosion model, GUEST, in the absence of data on runoff rates II.(*) Four case studies from China, Malaysia, and Thailand.
January 1, 1999... Abstract Runoff rates were estimated from rainfall rates and runoff amounts for 4 experimental sites in China, Malaysia, and Thailand before a physically based erosion model GUEST was used to determine the soil erodibility parameter and...

Comparing observed and simulated water storage during drainage to select hydraulic parameters for volcanic soils.(Review)
January 1, 1999... Abstract In soil-water modelling, hydraulic parameters must be chosen carefully to simulate water fluxes accurately. This study aimed to parameterise the Soil Water Infiltration and Movement (SWIM) model for sandy volcanic soils that are...

Simulation of picloram, atrazine, and simazine transport through two New Zealand soils using LEACHM.(Review)
January 1, 1999... Abstract Picloram, atrazine, simazine, and bromide were applied to 2 sites, a Twyford fine sandy loam and a Te Awa silt loam, located in Hawkes Bay, New Zealand, and monitored at approximately monthly intervals using suction cup samplers...

Water and bromide movement in a Vertosol under four fallow management systems.(Review)
January 1, 1999... Abstract Recent work on the Hermitage long-term fallow management found increased rates of anion movement under zero tillage systems compared with conventional tillage. Four separate experiments have been used to determine relative rates...

Polymer effects on surface mechanical strength of a crusting loessial soil.(Review)
January 1, 1999... Abstract Addition of synthetic polymers to crusting soils generally improves seedling emergence and this is thought to be caused by lower mechanical strength of the crusted soil surfaces. The objective of the present study was to evaluate...

Soil indicators of pre-European seabird breeding in New Zealand at sites identified by predator deposits.
January 1, 1999... Abstract Soil samples (0-15 cm) from 2 sites identified by palaeontological methods as pre-European seabird breeding sites (Annandale, Ardenest) were compared with a control site (Ngarua; no seabird breeding). All sites had moderately...

Dissolution of phosphate rock fertilisers in some soils of Okinawa, Japan.
January 1, 1999... Abstract The ability of phosphate rock (PR) to dissolve rapidly in soil is a primary concern in its direct application as P fertiliser. The dissolution of 4 PR materials (Togo, South Africa, Florida, Morocco PRs) in 15 soil samples in...

Soil nitrogen mineralisation and organic matter composition revealed by [sup.13]C NMR spectroscopy under repeated prescribed burning in eucalypt forests of south-east Queensland.
January 1, 1999... Abstract The effects of burning on in situ extractable nitrogen ([MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII]) and net N mineralisation following scheduled fuel reduction burns in repeatedly burnt dry and wet sclerophyll forest...

The influence of the soil matrix on nitrogen mineralisation and nitrification III(*). Predictive utility of traditional variables and process location within the pore system.
January 1, 1999... Abstract Regression analysis was used to examine the importance of organic nitrogen (%N), soil water content ([Theta] v), soil pH, and C:N ratio for predicting N mineralisation in a small field plot. Undisturbed soil cubes (c. 1.7...

Soil organic carbon dynamics under long-term sugarcane monoculture.
January 1, 1999... Abstract Comparisons of soil samples from virgin sites or sites recently planted to sugarcane (new) with sites that had been under cane production for many years (old) were made to investigate the potential impact of cane production on...

The influence of surface incorporated lime and gypsiferous by-products on surface and subsurface soil acidity. I. Soil solution chemistry.
January 1, 1999... Abstract Lime, fluidised bed boiler ash (FBA), and flue gas desulfurisation gypsum (FGDG) were incorporated in the top 50 mm of repacked columns of either an Allophanic (the Patua sand loam) or an Ultic (the Kaawa clay loam) soil, at rates...

The influence of surface incorporated lime and gypsiferous by-products on surface and subsurface soil acidity. II.(*) Root growth and agronomic implications.
January 1, 1999... Abstract Lucerne (Medicago sativa. L) root elongation in acid soils amended by gypsiferous coal combustion by-products was investigated in a glasshouse study. Lime, fluidised bed boiler ash (FBA), and flue gas desulfurisation gypsum (FGDG)...

Prediction of cadmium concentrations in potato tubers (Solanum tuberosum L.) by pre-plant soil and irrigation water analyses.
January 1, 1999... Abstract Potato tubers can accumulate high concentrations of cadmium (Cd) in edible portions, so that techniques to determine high risk Cd environments are required by growers. The use of combined soil and irrigation water analyses prior...

Formation, ecology, and geography of Cryosols of an ice-free oasis in Coastal East Antarctica near Casey Station (Wilkes Land).
January 1, 1999... Abstract New soil studies in the cold suggest that in the terrestrial ecosystems of the coastal regions of the antarctic continent, soil formation and chemical weathering occur to a greater extent than previously expected. This paper...
