Soil science

Soil science deals with 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 per se; and these properties in relation to the use and management of soils.

Sometimes terms which refer to branches of soil science, such as pedology (formation, chemistry, morphology and classification of soil) and edaphology (influence of soil on organisms, especially plants), are used as if synonymous with soil science.

The diversity of names associated with this discipline is related to the various associations concerned.

Indeed, engineers, agronomists, chemists, geologists, geographers, biologists, microbiologists, sylviculturists, sanitarians, archaeologists, and specialists in regional planning, all contribute to further knowledge of soils and the advancement of the soil sciences.

United Against Soil Erosion: German Farmers in Georgia

United Against Soil Erosion: German Farmers in Georgia

Deutsche Welle (Nov. 4, 2012) Less rainfall due to climate change and strong mountain winds are causing serious soil erosion in Georgia. The ongoing effects of overforestation and overgrazing during the Soviet era are exacerbating the problem. Even though Georgia's soil is richer in minerals than Germany's, soil erosion has reduced harvests there by up to 40 percent. Now German farmers are providing tips to their Georgian counterparts to help them slow down soil erosion.

Farming Revolution in South Africa

Farming Revolution in South Africa

Deutsche Welle (Feb. 20, 2012) A new project in South Africa is taking organic waste that would otherwise be left to simply decay in garbage dumps and processing it in a special facility belonging to the South African company Reliance. There, it is converted it into microbiological compost. The project prevents some 100,000 tons of methane gas being emitted into the atmosphere each year. In addition, the compost helps to improve the quality of the soil, makes plants more robust and helps farmers cut down on the use of pesticides. It's also helping South Africa tackle one of its biggest problems: the massive use of chemical fertilizers in the country has made the ground infertile, caused soil erosion and led to contaminated water.

We Must Genetically Engineer Babies to Stop Disease

FORA.tv (Feb. 13, 2013) Imagine a world free of genetic diseases, where parents control their offspring's height, eye color and intelligence. The science may be closer than you think. Genes interact in ways that we don't fully understand and there could be unintended consequences, new diseases that result from our tinkering. But even if the science could be perfected, is it morally wrong? Would it lead to eugenics and a stratified society where only the rich enjoy the benefits of genetic enhancement? Or would the real injustice be depriving our children of every scientifically possible opportunity?
