The project also examines problems of the global commons, as well as more local problems such as air pollution, water pollution, desertification and soil degradation. [5] Due to natural interdependencies, local environmental pollution can be transformed into global changes.
Soil bulk density, when determined at standardized moisture conditions, is an estimate of soil compaction. [60] 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.
The Global Soil Partnership planned a website, logo and activities for The International Year of Soil, and agricultural and environmental organizations around the world held local events to contribute to the special year. [11] [12] [13] The United States Department of Agriculture held a kick-off event. [14]

Soil science is the study of soil as a natural resource on the surface of the Earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils; and these properties in relation to the use and management of soils.
Soil geography deals with the distribution of soils across the terrain. This discipline, between geography and soil science, is fundamental to both physical geography and pedology . [ 9 ] [ 10 ] [ 11 ] Pedology is the study of soils in their natural environment.

Get your telescope ready in September, when Saturn will take center stage in the sky and shine brighter than at any other point in the year. The planet will reach opposition on Sept. 21, around ...
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 ...
