Ebook "Fundamentals of soil science (8th edition)" revision of a bestselling text shows that soil is three-dimensional and dynamic. This concept is developed in the first two chapters and is built on throughout the book. Chapters 3 through 7 explore soil physical properties and water, with expanded coverage of tillage and traffic and an increased emphasis on water and wind erosion processes. Chapters 8 through 11 discuss the biological aspects of soils as well as their mineralogical and chemical properties.

This study aims to evaluate the effect of fire on soil properties at Zone A5, Tram Chim National Park, Tam Nong district, Dong Thap province. Findings indicated that soil type was acid sulfate, soil structures were clay, clay-silt and silt-clay. pH was low while moisture was high. Electrical conductivity and bulk density were in the tolerance range for the Eleocharis community.

The sorption isotherms were best described by the Freundlich model rather than Langmuir or linear models. We determined that using wood fibre in constructed wetlands would require around 35–66% less area to remove the selected micropollutants, compared to soil as matrix. Thus our results show the potential of using hydroponic substrata such as wood - and coconut fibre to both remove micropollutants in, and reduce the footprint of constructed wetlands.

Soil type is a vital determinant of soil fertility because of its characteristic biological, chemical, and physical properties. However, the soil fertility of upland soil is probably changed by different agricultural management practices regardless of soil type. This study investigated the features of soil fertility (bacterial biomass, total carbon (TC), and total nitrogen (TN)) in upland fields in Japan. One thousand soil samples from different soil types were collected from upland fields located on 36 prefectures in Japan.

Calotropis procera is a wild species that is drought-resistant and plays a number of economic and ecological uses. The species is important in soil fertility improvement, pollution control by monitoring sulphur dioxide emissions in the air and suitable indicator of exhausted soil. This study was undertaken in drylands of South Eastern Kenyato evaluate the species‟ soil ecology and ability to bioaccumulate heavy metalsThe objectives of the research were to determine the soil chemical and physical properties for survival of C. procera and to determine the ability of C.

A pot experiment was conducted during kharif season of 2016-17 and 2017-18 in completely randomized design with two lime levels (0 and ¼ lime of LR), four phosphorus levels (0, 13.4, 26.8 and 40.2 mg P2O5 kg-1 ) and three boron levels (0, 0.45 and 0.90 mg B kg-1 ) to study the treatment effect on nutrient content and uptake of maize and soil properties. It was observed that lime had a significant effect on biomass yield, nutrient content and uptake of maize.

Conserving natural capital and optimizing factor productivity in semi-arid regions has been a great challenge in achieving sustainability of the production system. Cotton-wheat and guar-wheat based cropping system plays a predominant role under evolving climatic scenarios by sustainable conservation of natural resources. In the present study, the effect of long-term zero-tillage practices on selected physico-chemical and microbiological properties was determined in different cropping system at 0-15 and 15-30 cm soil depth in Mahendergarh (Tigra) district of Haryana (latitude- 28.

A long term field experiment was conducted since kharif 2015 for evaluating the effect of inorganic and organic sources of nutrients on soil physical properties and productivity on direct seeded rice ( Oryza satia L.) – MTU1010 under rainfed midland situation at Bastar plateau zone at S. G. College of Agriculture and Research Station, Jagdalpur, Chhattisgarh. Random block design was used with twelve treatments and four replications to carry out experiment. The full recommended dose of fertilizer for rice crop was 100kg ha-1 Nitrogen, 60 kg ha-1 phosphorus and 40 kg ha-1.
