Phosphorus requirements of microbial biomass in a regosol and an andosol
Soil Biology and Biochemistry, 1998Abstract The critical P concentration in microbial biomass (defined as that required to achieve 80% of the maximum synthesis of microbial biomass C) and minimum amount of available P to obtain the critical P concentration in the microbial biomass of a granitic regosol and an andosol of Japan were examined. Phosphorus was applied as KH2PO4 at rates of

Distribution of copper and zinc fractions in a Regosol profile under centenary vineyard
Environmental Earth Sciences, 2020Phytosanitary treatments using Bordeaux mixture or zinc (Zn) fungicides are often used in vineyards, which increase soil copper (Cu) and Zn contents. In this study, the accumulation and distribution of Cu and Zn fractions (water soluble, exchangeable, oxidic, organic and residual fractions) was evaluated along a Regosol profile cultivated with vine ...

Proton Budgets of Forest Ecosystems on Volcanogenous Regosols in Hokkaido, Northern Japan
Water, Air, and Soil Pollution, 1998The proton budgets of deciduous and coniferous forest ecosystems on volcanogenous regosols in Hokkaido, northern Japan, were studied by measuring the biogeochemical fluxes (atmospheric deposition, canopy leaching, vegetation uptake and leaching from soil) at each site during a three year period.

Regosolic soils of Canada: Genesis, distribution and classification
Canadian Journal of Soil Science, 2011VandenBygaart, A. J. 2011. Regosolic soils of Canada: Genesis, distribution and classification. Can. J. Soil Sci. 91: 881–887. Regosolic soils of the Canadian System of Soil Classification are those soils that are weakly developed and do not contain a recognizable B horizon at least 5 cm thick. They must be able to support plant life and thus represent

Minimum available N requirement for microbial biomass P formation in a regosol
Soil Biology and Biochemistry, 1999A soil incubation experiment was conducted to determine the effects of N application on microbial biomass C and P and to estimate the minimum requirement of available N for microbial biomass P formation. A granitic regosol soil was amended with N (as (NH4)2SO4) at rates of 0, 200, 400 or 800 mg N kg−1, C (as rice straw) at 2100 mg C kg−1 and P (as ...

Successful Soil Remediation and Reforestation of a Calcic Regosol Amended with Composted Urban Waste
Arid Land Research and Management, 2003Experimental reforestation of highly degraded gypsiferous semiarid soil was successfully carried out after a 400 Mg ha m 1 input of composted urban waste. Changes in soil physical properties, aggregate stability, available nutrients, and seedling growth (Pinus halepensis, Spartium junceum, Quercus coccifera, Pistacia lentiscus and Santolina ...

Abstract Differences in fabric may explain why relationships between aggregate stability and soil color have never been reported for a relatively narrow-ranging population of soils. Therefore, three size fractions (1–2, 0.25–1, and 0.05–0.25 mm) of 25 topsoils (75 samples) from a Regosol–Umbrisol soilscape (Sierra Nevada, SE Spain) were characterized

Quantifying rainfall–runoff relationships on the Dera Calcic Fluvic Regosol ecotope in Ethiopia
Agricultural Water Management, 2008Abstract Droughts, resulting in low crop yields, are common in the semi-arid areas of Ethiopia and adversely influence the well-being of many people. The objective of this study was to assess the benefit that in-field rainwater harvesting (IRWH) would have, compared to conventional tillage, on maize yields on a semi-arid ecotope at Dera situated on ...
