Why Soil Genesis?orizon decreases or increases, sedimentary layering disappears, etc. Mostly, such changes are slow, and can be seen only after decades to millenia. So most soil properties that change during soil formation are relatively stable. Sometimes, however, effects of soil formation can be seen within weeks 作者: 草本植物 時間: 2025-3-22 17:58

Textural Differentiationrited from the substrate (e.g., textural variations in sediments). Frequently, however, the differences are due to soil forming processes. Textural differentiation leads to topsoils and subsoils that are either finer, or coarser than the parent material. At least eight processes can result in textural differentiation:作者: 伴隨而來 時間: 2025-3-27 05:03 作者: cardiopulmonary 時間: 2025-3-27 05:20 作者: 蜿蜒而流 時間: 2025-3-27 10:21 作者: 昏迷狀態(tài) 時間: 2025-3-27 14:00 作者: BUCK 時間: 2025-3-27 20:38
