A mixture of soil particles ranging in size from coarse to fine. Processing involve crushing oversized particles and screening where it is necessary to secure the desired grading. The requirements of a satisfactory soil aggregate surface are; Stability, Resistance to abrasion, Resistance to penetration of water, Capillary properties to replace moisture lost by surface evaporation

Land use pressures are particularly mounting on the edges of the urban areas; much of the land resources and capital lies in private hands. This puts a heavy responsibility on public bodies to maintain the balance between urban development and conservation needs. Urban planners do not seem to realize that class I and class II agricultural soils are a scarce and

Excessive size both in population and geographical area 
 Where the economic base of the cities is inadequate to cope with problems created by excessive size Tremendous amount of land being gobbled up by sprawl of cites, especially giant conurbation. The loss of agriculture land to urban/industrial sprawl is of grave concern. Once loss this prime land cannot be replaced.

To measure or estimation the consumptive use there are two main methods: Direct Methods/Field Methods Empirical Methods Pan evaporation method. In this method of estimation of water consumptive use, soil moisture measurements are taken before and after each irrigation.

There are six characteristics of planning which are of prime importance: The use of available resources as economical as possible, so as to achieve the greater possible measures of improvement within limited resources. Sustainability means that there should be a balance between people and resources. Use of resources in such a way that the environment should not
