, sunlight, minerals, land, soil and fossil fuels to exist. all these useful raw materials are called natural resources. the picture below gives us a few examples of the numerous things we obtain from natural resources. different types of natural resources – renewable and nonrenewable resources...
Moor has a low-quality class (0.32), while rice fields (0.40) and secondary forest (0.39) have a medium class. The indicators that become the limiting factor of soil quality based on the correlation test results are pH, CEC, and K-Available. Based on the limiting factors obtained, ...

Different kinds of soil conservation methods are used by farmers to protect their land from damage by farming and the forces of nature. One important form of soil conservation is the use of windbreaks. Windbreaks are barriers (屏障) formed by trees and other plants with many leaves. Farmers pl...
The response sensitivity of bacteria in the silt and clay fraction was higher than that in the macroaggregate fraction, but the response sensitivity of fungi in the macroaggregate fraction was higher than that in the silt and clay fraction. Relationships and path analysis between soil aggregate ...
The lack or limited substitution possibilities between types of feed suggests that beef farms are vulnerable to feed price increases. We find statistically significant evidence of allocative inefficiency irrespective of the quality of soil, which takes the form of over-utilization of purchased cattle ...
Biogeographic patterns in soil bacterial communities and their responses to environmental variables are well established, yet little is known about how different types of agricultural land use affect bacterial communities at large spatial scales. We repo
True or False: If two corresponding angles of two triangles are proportional, then the two triangles are similar. What is a type of unit that could be used to measure mass? Calculate the mass of soil in an area of 1 ha ...
The results revealed the following findings: (i) contrasting rainfall critical conditions for failure can trigger similar landslide types, although they may vary in size and be spatially constrained by different predisposing conditions, particularly lithology and soil type; (ii) landslide susceptibility ...
In addition, the starch and amylose content of the potatoes were determined using enzymatic methods, and the correlation between soil elements and starch content in Dingxi potatoes was analyzed. The results indicated that the flavor scores for the samples “DX-DP,”“DX-LS,”“NM-XY,”“JB-...
