There are majorly 12 factors influence Soil fertility
Infiltration of water.
Active Soil life.
Content of organic matter.
Minerals present in the soil.
Acidity or Soil pH.
Water Retention capacity of soil.
Water draining ability of the soil.
Furthermore, how can we improve the fertility of soil?
Add Organic Matter
Add manures for nitrogen. All livestock manures can be valuable additions to soil — their nutrients are readily available to soil organisms and plants.
Tap chicken power to mix organic materials into the soil.
Plant cover crops.
What makes soil fertile?
SOIL FERTILITY. Crops need nutrients just like people do. A fertile soil will contain all the major nutrients for basic plant nutrition (e.g., nitrogen, phosphorus, and potassium), as well as other nutrients needed in smaller quantities (e.g., calcium, magnesium, sulfur, iron, zinc, copper, boron, molybdenum, nickel).
What are the characteristics of a fertile soil?
Fertile soil has the following characteristics:
It is rich in nutrients necessary for basic plant nourishment.
It consists of adequate minerals such as boron, chlorine, cobalt, copper, iron, manganese, magnesium, molybdenum, sulphur and zinc.
It contains soil organic matter that improves the structure of the soil.
