Although particle size fractions are inherent soil properties, their variation sometimes could be associated with the management practices, mainly through mismanagement of soil resources without appropriate conservation measures, resulting directly to the changes in particle size distribution through removals by sheet and rill erosions (Toy et al. 2002).
In a spatial Daisyworld however, the distribution of soil resources is a matter of locally available fertile soil patches.
Consequently, any effort made to improve water use in irrigation practices will have a marked effect on sustainable agriculture and on conservation of soil and water resources.
Specifically, we need to address the following issues: (1) demonstrate causal relationships between soil quality and ecosystem functions, including biodiversity conservation, biomass production and conservation of soil and water resources.
As a consequence, professional foresters have increasingly become involved in activities related to the conservation of soil, water, and wildlife resources and to recreation.
Combating desertification, a marked problem in arid, semi-arid and other desertification-affected areas of the world, encompasses the management of water resources and the conservation of soil properties.
Organic food is produced by farmers who emphasize the use of renewable resources and the conservation of soil and water to enhance environmental quality for future generations.
According to the USDA, any food sporting "organic" on its label must be "produced by farmers who emphasize the use of renewable resources and the conservation of soil and water to enhance environmental quality for future generations".
Similar minutiae govern wildlife conservation, pest management, conservation of soil and water, housing and services for workers, labour contracts, recycling and community relations.
