Water pollution includes soil erosion. 5. The main idea of this passage should be ___. J. to introduce the kinds of pollution and the ways to control it K. to introduce the harmful chemicals and soil erosion L. to introduce the alternative energy and the ways to use it 反馈 收藏...
The effect of combining biological measures and engineering measures was much better than the single biological measure to control the soil erosion in the dump slope, and it was one of the most effective ways to control the soil erosion in the dump slope. In summary, by setting up different ...
Adapting to the conditions of the ecosystems under study, passive sampling methods have been modified and improved upon in various innovative ways. The present study compares the sampling efficiencies of nets, bowls, and one such innovative height-adjustable modification of passive bowl trapping in ...
Once you have your landscaping and garden plants planted, they need protection from dastardly weeds and harsh weather. Mulch is one of the best ways to keep weeds away, keep your plants healthy and thriving, and increase curb appeal. But what are the different types of much, and which one...

Minimum Ψpd values in BV were -0.28MPa, -1.79MPa, -2.16MPa in MM were -0.14MPa; -1.58MPa, -2.72MPa, in EM were -0.16MPa; -2.37MPa, -2.76MPa for Control, SWS1 and SWS2 respectively. Notice that such low predawn total leaf water potential are really exceptional, and at that ...
Furthermore, bare fallow may lead to further degradation of the fertilized soil due to water or/and wind erosion, which poses another great threat to sustainable production. Therefore, it is critical to pursue methods to effectively use the natural resources during the rainy season to prevent the...
Biotic factors, such as vegetation type and restoration strategies (i.e., passive (natural regeneration) versus active (e.g., tree planting), Brancalion and Holl2020) are also important determinants of soil respiration because they control the quantity and quality (chemical composition) of litterfa...
In degraded ecoregions, the net growth rate of forests was twice as high as the expansion of built-up land, which may have been controlled in both bottom-up and top-down ways. On the one hand, farmers who are constrained by resources in degraded ecoregions actively get rid of poverty, so...
soil particles deposited on the slope in different ways so as to achieve the control of dewatering and maintain soil quality,which can also reduce non-point source pollution.So it's necessary to choose an appropriate slope drainage layout measure according to soil properties,gradient and land use...
