The Philippines' Bureau of Soils and Water Management (Filipino: Kawanihan ng Pamamahala sa Lupa at Tubig, [1] abbreviated as BSWM), is an agency of the Philippine government under the Department of Agriculture responsible for advising and rendering assistance on matters relative to the utilization of soils and water as vital agricultural resources.
A full geotechnical engineering soil description will also include other properties of the soil including color, in-situ moisture content, in-situ strength, and somewhat more detail about the material properties of the soil than is provided by the USCS code. The USCS and additional engineering description is standardized in ASTM D 2487. [4]
Soil bulk density, when determined at standardized moisture conditions, is an estimate of soil compaction. [3] Soil porosity consists of the void part of the soil volume and is occupied by gases or water. Soil consistency is the ability of soil materials to stick together. Soil temperature and colour are self-defining.
Digital soil mapping (DSM) in soil science, also referred to as predictive soil mapping [1] or pedometric mapping, is the computer-assisted production of digital maps of soil types and soil properties. Soil mapping, in general, involves the creation and population of spatial soil information by the use of field and laboratory observational ...
Cavite is composed of several soil types according to soil surveys conducted by the Bureau of Soils and Water Management (BSWM). Classification of soil types in a specific area is a very important consideration in identifying its most fitted land-use. This way, utmost productivity can be achieved.
Agricultural water management in the Philippines is primarily focused on irrigation. The country has 3.126 million hectares of irrigable land, 50% (1.567 million hectares) of which already has irrigation facilities. 50% of irrigated areas are developed and operated by the government through the National Irrigation System (NIS). 36% is developed by the government and operated by irrigators ...
Soil consists of a solid phase of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution). [ 1 ] [ 2 ] Accordingly, soil is a three- state system of solids, liquids, and gases. [ 3 ]
A soil type is a taxonomic unit in soil science. All soils that share a certain set of well-defined properties form a distinctive soil type. [1] Soil type is a technical term of soil classification, the science that deals with the systematic categorization of soils. Every soil of the world belongs to a certain soil type. Soil type is an ...
