OBJECTIVE FORESTRY

Detailed explanation-1: -Class IV (4) soils have very severe limitations that restrict the choice of plants or require very careful management, or both.

Detailed explanation-2: -CLASS I IA1 and 1A2 These classes consist of medium to well-graded sands and clayey sands. IA3 This class consists of fine grained sands, silty sands and clayey sands that are usually less dense but exhibit excellent bearing capacity.

Detailed explanation-3: -Land capability classification (LCC) may be defined as a system of grouping land in to various classes based on inherent limitations imposed on sustained use by soil attributes, topography, drainage and climate. The guiding principle underlying LCC is “use land according to its capability and treat it as per its need”.

Detailed explanation-4: -Class 1 soils have slight limitations that restrict their use. Class 2 soils have moderate limitations that restrict the choice of plants or that require moderate conservation practices. Class 3 soils have severe limitations that restrict the choice of plants or that require special conservation practices, or both.

Detailed explanation-5: -Land Capability unit is a grouping of soils that have about the same responses to cultivated crops and pasture plants. Yields are also used as criteria in establishing the Capability units. The second category the Capability sub-class is a grouping of capability units having similar kinds of limitation and hazards.
