The extent of Al toxicity varies substantially with the type of plant and the Al species. Figure 9.6 summarizes the sensitivity of common field crops and forage species to soil pH (measured in 0.01 M CaCl2) and Al (Slattery et al., 1999). While the toxicity of monomeric Al3+ (Al(H2O)...
GPR type (air-launched GPR) uses the magnitude of the reflection from the ground surface to measure the dielectric permittivity and has a sampling depth of less than 5 cm, but the accuracy of the data is greatly diminished by vegetation, uneven soil surfaces, and vertical variations in water...

Rhizosphere ecology is driven by a combination of the physical architecture of the soil matrix, coupled with the spatial and temporal distribution of rhizodeposits, protons, gases, and the role of roots as sinks for water and nutrients. Consequences for plant growth and whole-system ecology are co...
Therefore, samples in this study were collected near phosphate rock chemical plants, Sichuan province, China. In this study, we used metagenomic to analysis the microbial community structure and function in Cd-contaminated soil and reveal the variations of the microbial community, which provided an ...
The third biophysical contributor to soil infertility and erosion in Haiti is its soil type. Soil formation (pedogenesis) begins with long-term weathering of the underlying parent rock, which in Haiti is predominantly volcanic rock or limestone [17]. The formation of Haitian soils has resulted in...
(Fig.2j). Total CO2fixation would be expected to decrease CO2emissions by up to 5.6%, depending on soil type30,31, suggesting the potential for only a small impact on our estimates of microbial C allocation to biosynthesis vs TCA cycle. Overall, these data suggest an increase in ...
Stocking rate– Typically refers to the number of cattle that can be run on a ranch, or more specifically the total pounds of a livestock type and class that can be run year-around. It is typically based on the number of animals that can be grazed on one-half of one-half (or 25%)...
The soil type, lithology and mineralogy also have been found to have a profound effect (da Costa et al., 2013). Some soil types are inherently more prone to provide these regulatory services effectively. Fine-textured soils with high organic matter, for example, will have a higher cation ...
Land use, soil type, and topography are the other key factors. Soil erosion by water is more widespread and its impact greater than that by wind. Climate change is likely to affect soil erosion by water through its effect on rainfall intensity, soil erodibility, vegetative cover, and patterns...
