1. In a soil profile, the depth of the different layers may vary widely and some layers may be missing altogether
2. In a fine textured soil, sand is predominant
3. Farmers used the term heavy soil for the clayey or fine textured soil.
4. In a Massive Soil Structure, water flow is rapid.
5. In the process of infiltration, the water seeps into the soil and the color of the soil
becomes lighter as it is wetted.
6. The soil has low infiltration rate when it seeps water at the rate of less than 15mm
hour.
7. Soil Texture influences the infiltration rate of soil
8. The capillary rise of a coarse textured soil reaches up to 80 cm.
9. Soil erosion by water depends on the rate of flow of surface runoff water.
10. In a Prismatic Soil Structure, water flow is rapid.
11. Contour lines are useful means to illustrate the topography of a field on a flat map.
12. A bench mark is a permanent mark established in a field to use as a reference
point
13. The depth of the groundwater table varies greatly from place to place, mainly due​
