What is Soil?
This definition is from the Soil Science Society of America.
(i) The unconsolidated mineral or organic material on the immediate surface of the Earth that serves as a natural medium for the growth of land plants. (ii) The unconsolidated mineral or organic matter on the surface of the Earth that has been subjected to and shows effects of genetic and environmental factors of: climate (including water and temperature effects), and macro- and microorganisms, conditioned by relief, acting on parent material over a period of time. A product-soil differs from the material from which it is derived in many physical, chemical, biological, and morphological properties and characteristics.
Agriculture has the power to decrease the greenhouse gases and to control climate change.
Climate and Weather
Weather is all the conditions in the atmosphere that are around us.
It is a combination of temperature, wind, humidity, and precipitation.
Climate is the total average of all weather occurring over a period of several years in a specific place.
There are diverse causes of soil pollution. Some of the more common types of pollutions are industrial chemicals, metal contamination, radioactive metals, agricultural chemicals, salts, and sewage.
Soil Organic Carbon
Soil organic carbon is the component of the soil organic matter that can be measured. Generally, organic matter in soil makes up 2 to 10% of soil's total mass and has effect on the physical, chemical and biological function of agricultural soil.
