1 Because of thin solum and lower soil loss tolerance, the ecosystem in Karst region is very fragile. The vegetation is difficult to recover after destruction.

2 I wonder whether Professor Solum has overstated the positive significance of these developments.

3 The rendering of the zhoufang the positive just right solum impersonate this magic power.

4 Field experiments were conducted to study effect of irrigation and water-fertilizer spatial coupling on corn N uptake and N residue in the solum (1.

5 In treating water leakage of reservoir, slurry emitting from solum may occur during leakage stoppage by pressurized water.

6 These soils are usually characterized by the higher fertility, thin solum, containing gravel and erode easily.
