The land system is a coupled human—environment system comprising land use, land cover, and terrestrial ecosystems Global Land Project, Land use connects humans to the biophysical environment. Conversely, the characteristics and changes in the biophysical environment influence our land-use decision-making. Thus, there is a continuum of states resulting from the interactions between natural biophysical and human social subsystems of land Fig. Though not always, the dynamics of this continuum generally moves toward increasing human dominance and impact. Thus, mitigating adverse environmental changes requires an improved knowledge of human impact on natural processes of the terrestrial biosphere.

Soil Composition

It is also known as "Amazonian dark earth" or "Indian black earth". Terra mulata "mulatto earth" is lighter or brownish in color. Terra preta owes its characteristic black color to its weathered charcoal content, [2] and was made by adding a mixture of charcoal, bone, broken pottery, compost and manure to the low fertility Amazonian soil. A product of indigenous soil management and slash-and-char agriculture, [3] the charcoal is stable and remains in the soil for thousands of years, binding and retaining minerals and nutrients. Terra preta is characterized by the presence of low-temperature charcoal residues in high concentrations; [2] of high quantities of tiny pottery shards ; of organic matter such as plant residues, animal feces , fish and animal bones, and other material; and of nutrients such as nitrogen , phosphorus , calcium , zinc and manganese.

Soil is our life support system. Soils provide anchorage for roots, hold water and nutrients. Soils are home to a myriad of micro-organisms that fix nitrogen and decompose organic matter, and armies of microscopic animals as well as earthworms and termites. We build on soil as well as with it and in it.
