soil fertility vs soil productivity?

Answer 1

Soil fertility is the characteristic of soil that supports abundant plant life. In particular the term is used to describe agricultural and garden soil.

Fertile soil has the following properties:

It is rich in nutrients necessary for basic plant nutrition, including nitrogen, phosphorus and potassium.
It contains sufficient minerals (trace elements) for plant nutrition, including boron, chlorine, cobalt, copper, iron, manganese, magnesium, molybdenum, sulfur, and zinc.
It contains soil organic matter that improves soil structure and soil moisture retention.
Soil pH is in the range 6.0 to 6.8.
Good soil structure, creating well drained soil.
A range of microorganisms that support plant growth.
It often contains large amounts of topsoil.
In lands used for agriculture and other human activities, fertile soil typically arises from the use of soil conservation practices

Soil formation, or pedogenesis, is the combined effect of physical, chemical, biological, and anthropogenic processes on soil parent material resulting in the formation of soil horizons. Soil is always changing. The long periods over which change occurs and the multiple influences of change mean that simple soils are rare. While soil can achieve relative stability in properties for extended periods of time, the soil life cycle ultimately ends in soil conditions that leave it vulnerable to erosion. Little of the soil continuum of the earth is older than Tertiary and most no older than Pleistocene.[7] Despite the inevitability of soils retrogression and degradation, most soil cycles are long and productive. How the soil "life" cycle proceeds is influenced by at least five classic soil forming factors: regional climate, biotic potential, topography, parent material, and the passage of time.

An example of soil development from bare rock occurs on recent lava flows in warm regions under heavy and very frequent rainfall. In such climates plants become established very quickly on basaltic lava, even though there is very little organic material. The plants are supported by the porous rock becoming filled with nutrient bearing water, for example carrying dissolved bird droppings or guano. The developing plant roots themselves gradually breaks up the porous lava and organic matter soon accumulates but, even before it does, the predominantly porous broken lava in which the plant roots grow can be considered a soil.

Answer 2

Soil Productivity And Soil Fertility

Answer 3

Soil fertility is the inherent capacity of the soil to produce crops while soil productivity is the ability of the soil to produce certain yield of a crop or crops.

Answer 4

Fertility is about the nutrients and tilth and such.

Productivity is about how much harvest you get.

Proper fertility increases productivity. But they are not the same thing. Productivity also depends on water, and temp, and how you plant and etc etc.....
