Soil hydraulic properties of a Nitisol in Kabete, Kenya [PDF]

open access: yes, 2012
Water relations are among the most important physical phenomena that affect the use of soils for agricultural, ecological, environmental, and engineering purposes. To formulate soil-water relationships, soil hydraulic properties are required as essential

Sulfur source effects on soil, vegetation indices, biomass, and uptake in potato

open access: yesAgrosystems, Geosciences & Environment
Sulfur (S) is necessary for amino acid production, disease resistance, protein synthesis, and nitrogen assimilation in plants. We tested the performance of three S sources (magnesium sulfate [EPTOP], gypsum, and ammonium sulfate [AS]) at two different ...

Boundary conditions for exploiting the cooperation of Aminobacter niigataensis MSH1 with Piscinibacter sp. K169 to support 2,6-dichlorobenzamide biodegradation in sand filters for drinking water treatment: role of cell density and organic carbon

open access: yesApplied and Environmental Microbiology
Aminobacter niigataensis MSH1 mineralizes the groundwater micropollutant 2,6-dichlorobenzamide (BAM) and is a candidate for bioaugmentation of sand filters in drinking water treatment plants (DWTP) to avert BAM-contamination. Piscinibacter sp.

Effect of windbreaks on wind speed reduction and soil protection against wind erosion

open access: yesSoil and Water Research, 2017
Windbreaks form efficient soil protection against wind erosion particularly at the time when soil cover is not protected by the cultivated plant vegetation cover. The objective of this research was to evaluate windbreaks efficiency in terms of wind speed
