Proper soil conservation techniques such as avoiding plowing and leaving crop residue on the ground can help keep more of the carbon in the soil.

The United Nations' Food and Agriculture Organization (FAO) and its Global Soil Partnership launched today a new programme to boost soil productivity and reduce soil degradation for greater food an

The UN's Food and Agriculture Organization (FAO) and the Global Soil Partnership on Wednesday launched a new program to help boost soil productivity by 30 percent in 47 African countries.

Soil biodiversity and soil organic carbon are vital to the way ecosystems function and they largely determine the role of land in producing food, storing water, and mitigating climate change. This report highlights how soil organic carbon and soil biodiversity provide the foundation for terrestrial ecosystem services.

Scientists will publish the first-ever analysis Monday of the global state of land and its ability to sustain a fast-growing human population that relies on it for 95 percent of all food.

Soil fertility has direct implications on the agricultural production scenarios of a region. Surface soil samples at 1 km grid were collected to assess the fertility status of Lakhimpur district (Assam) in North East India. Fertility parameters like soil organic carbon, available nitrogen, phosphorus, potassium, iron, manganese, zinc and copper were determined using standard analytical procedure.

Inorganic phosphorus (P)-solubilizing bacteria (IPSB) and organic P-mineralizing bacteria (OPMB) were isolated from bacteria that were first extracted from the rhizosphere soil of a natural wetland and then grown on either tricalcium phosphate or lecithin medium. The solubilizing of inorganic P was the major contribution to P availability, since the isolated bacteria released much more available P from inorganic tricalcium phosphate than lecithin.

Nearly a third of the carbon dioxide released into the atmosphere annually can be traced back to bacteria living in the soil, where they break down plant and animal matter for energy.
