For both soil quantities, the amount of humic matter extracted from soil was significantly smaller than that for the untreated control soil.
The data are collected by orbiting satellites.The spectrum of this radiation which can be in the form of either natural sunlight or artificial radar can reveal, with surprising precision, the properties of the soil, the quantity of crop being grown, and the levels in those crops of chlorophyll, various minerals, moisture and other indicators of their quality.
Soil microorganism quantity, soil enzyme activities were both higher in 0 20 cm layer than in 20 40 cm layer.
Soil microorganism quantity and enzyme activity changes because of mining activities (Quadros et al. 2016).
The extremely toxic metal Cd was founded in contaminated soil in quantity that exceeded normal content from R area but under alert threshold values.
This soil loss quantity would be favored by the erosion factors controlling soil loss, such as steep slopes (nearly 40% of the total surface area of the watershed showed a slope value more than 20%), moderately erodible lands (57% of lands showed a K-factor between 0.45 and 0.5), and degraded plant cover.
In order to explore the changing rule of soil microbial quantity and respiratory capacity under different construction machineries and rolling times, and find the optimal processing conditions, an experiment was set up and a simulation experimental area was chosen, in which we simulated the main types of reclamation in coal mine area.
First, soil DNA quantities needed for robust community profiling were determined.
Zhang (2001) reported that thinning plantation stands increased soil microbe quantities, strengthened soil enzyme activities, decreased bulk density, and enhanced soil total porosity degree and available nutrients.
This can happen especially where soil contains quantities of cement, either as landfill or building foundations, and can be treated with iron chelate or sulfate.
