Wetland ecology characterizes these areas by their surface water hydrology, their soil and terrain characteristics, and the prevailing climatic conditions (Brinkman and Blokhuis, 1986). Table 1 gives some of the important functions, products and attributes of wetlands (Harou, 1995). TABLE 1 Wetland values. Therefore, the conservation and management of the wetlands have to be considered in a broader context of integrated and sustainable natural resources planning and management.

Soil Texture Soil texture affects physical and chemical properties that influence crop growth. Figure 5. Examples of soil structure with pore space. Soil Tilth Soil tilth is a description of the physical condition of the soil in relation to plant growth, ease of tillage and fitness as a seedbed. In the broadest sense, soil texture refers to the feel of the soil, its coarseness or fineness. More specifically, it is the soil’s relative proportions of sand, silt and clay. A soil containing equal percentages of sand, silt and clay is classified as a loam (the ideal soil). It depends on both the degree and stability of soil aggregates. Good, fair and poor are the common descriptive terms for tilth.
