These assumptions provide a simple formula for assessing PDW in terms of the number of wells. More complex models of production can be invoked (rather than just a simple exponential as reported here); equally, more complex models of well development with time, or of economic threshold limits, ...
prolonging soil moisture retention, thereby delaying the advent of abiotic stress and ultimately improving IWUE30,35,36. A multitude of studies have identified a variety of advantages associated with the utilization of CH, such as improved plant transpiration, enhanced growth, chemical versatility, nutr...
There is a wide range of construction types of wave barriers, varying from very stiff concrete walls or row of piles to very flexible gas mattresses or wave impeding barriers, where the latter is based on the cut-off frequency of a soil layer over rigid bedrock. Because of screening ...
Sodic paddy soil improver of the present invention, compared with PFS, while maintaining the same effect of reducing the unit cost of the formula from 9.4 to 15%. 与硫酸铝土壤改良剂相比,本配方的高分子聚合物具有更好的絮凝效果和更高的改良效率,同时将土壤活性铝浓度控制在对作物无害的低浓度水平....
We also checked that the PCR efficiencies for each primer set were similar (0.8–1.2), thereby allowing us to simplify Pfaffl's model formula for calculating relative expression [45] with 2- ΔΔCq (data not shown). Method sensitivities The Cq values obtained on a subset of 23 genes were...
Cumulative N2O–N per unit of grain yield, however, was reduced by 80% with PCU8% compared with uncoated urea. Results indicate that polyurethane-coated urea performs similarly to uncoated urea for maize production while reducing soil N2O emissions up to 60–80%, with an efficiency factor ...
We used different agricultural seasons at each site as a means to account for the diversity of the environmental conditions (other than those of the soil: i.e., climate, pests, etc). Consequently, the elementary unit of the analysis carried out in the present study is the small field plot...

Examining the soil–heavy metal level of the Mianyang thermal power plant area in Sichuan, China, Zhao et al. [18] proposed an effective method of discernment for the ecological remediation of soils’ heavy metals. 2.5. Research Gaps Existing studies related to both brownfields and PPP are ...
