Genesis of soils across a late Quaternary volcanic landscape in the humid tropical island of Leyte, Philippines.(Report)
August 1, 2008... Introduction Despite the increase in our understanding of the nature and properties of volcanic-ash derived soils (including Andisols) in the last few decades (e.g. Fernandez-Caldas and Yaalon 1985; Shoji et al. 1993), few studies have...

Effect of biosolids on the organic matter content and phosphorus chemical fractionation of heated volcanic Chilean soils.(Technical report)
August 1, 2008... Introduction Soils derived from volcanic materials constitute approximately 70% of arable land in central-southern Chile. These soils are rich in iron oxides, with high phosphate retention, a variable charge dependent on pH and ionic...

Plant-available nitrogen supply from granulated biosolids: implications for land application guidelines.(Technical report)
August 1, 2008... Introduction The safe beneficial use of reclaimed wastewater biosolids is a global issue of relevance to all societies. Approximately 190 000 t of biosolids is produced each year as residual solids at sewage treatment plants in the Sydney...

Using poultry litter biochars as soil amendments.(Report)
August 1, 2008... Introduction Biochars refer to the carbon-rich materials produced from the slow pyrolysis (heating in the absence of oxygen) of biomass. Recently, there has been much interest in biochars as soil amendments to improve and maintain soil...

Base cation availability and leaching after nitrogen fertilisation of a eucalypt plantation.(Technical report)
August 1, 2008... Introduction Fertilisation of many Australian forest soils with phosphorus (P), nitrogen (N), and in some cases other nutrients, is necessary to achieve high growth rates of eucalypt plantations. (Cromer et al. 1993; Bennett et al. 1996;...

Effects of different soil management practices on winter wheat yield and N losses on a dryland loess soil in China.(Report)
August 1, 2008... Introduction Growers in the Loess Plateau usually apply excessive fertiliser as insurance so that N will not limit yields. Fertiliser use increased until the 1990s in the Loess Plateau, and has been maintained since then at annual levels...

Evaluation of sustainability of mixed food crop fields by monitoring particulate organic matter (POM) status and nutrient concentrations.(Technical report)
August 1, 2008... Introduction Soil organic matter (SOM) is considered to be one of the major components in the evaluation of soil quality and fertility in agricultural systems, and after change of one vegetation cover type to another (Sikora et al. 1996)....

Soil quality assessed by carbon management index in a subtropical Acrisol subjected to tillage systems and irrigation.(Technical report)
August 1, 2008... Introduction In order to minimise risks of crop failures due to droughts and improve crop yields, Brazilian farmers have been increasing the sprinkler-irrigated land area at a rate of 85 000 ha per year (1990-2004), so that about 1.37 Mha...

Pedotransfer functions for predicting the hydraulic properties of Indian soils.(Technical report)
August 1, 2008... Introduction Seeking solutions to the increasingly complex agricultural production environments spread across the diverse agroecologies of a vast country such as India requires development of sound and well-organised agri-informatics. One...

Relations between sorption behavior and electrokinetic remediation effect in soils contaminated with heavy metals.(Technical report)
August 1, 2008... Introduction Soil pollution has become increasingly serious in recent years throughout the world (Virkutyte et al. 2002). Soil contaminated by heavy metals becomes more evident with increasing pollutants emitted from electroplate plants in...
