Soil physics is the study of soil physical properties and processes. it is applied to management and prediction under natural and managed ecosystems. Soil physics deals with the dynamics of physical soil components and their phases as solids, liquids, and gases. lt draws on the principles of physics, physical chemistry, engineering, and meteorology. it is especially important in this day and age because most farmers require ana understanding of agro ecosystems. Soil physics applies these principles to address practical problems of agriculture, ecology, and engineering. Agro physics is closely related to biophysics, but is restricted to the biology of the plants, animals and soil involved in agricultural activities and biodiversity. The book includes procedures for using soil physics in agriculture and estimating soil physical properties from more readily available data and shows how soil physical data can be integrated into land planning and management decisions. Contents: introduction; Evaluation of Soil Structure; Examination and Description of Soils; Preparing for Field Sampling; Biological and Chemical Aspects of Soil Productivity; Soil Quality Considerations in the Selection of Sites for Aquaculture; Soil Moisture Measurement instrumentation; Physical Properties of Tropical Sandy Soils.
