Every plant extracts carbon, nitrogen and trace elements from the soil. After a few years, the soil doesn't have many nutrients left in the soil.
Farmers replace the nutrients in the soil with fertilizer, or by rotating their crops to plant something different each year. For example, farmers will plant a crop of clover every few years, and the clover extracts nitrogen from the atmosphere. When the farmer plows the clover back into the soil, the nitrogen remains in the soil. Every few years, the farmer may plant hay or grass, and allow cattle to graze on the grass. The cattle manure is left in the fields, and plowed under the next year; this also restores the missing minerals and nutrients.
One very popular natural fertilizer was "guano", or bird manure. Over centuries of time, birds nesting on certain islands would leave - literally! - MOUNTAINS of manure, and this could be mined and shipped to farmers as fertilizer.
Since the early 1900s, chemists have created artificial fertilizers, which are less expensive and less dangerous.
Soils in India can lose fertility due to factors such as overuse of chemical fertilizers, improper irrigation practices leading to salinization, erosion of topsoil due to deforestation and poor soil management practices, and contamination from industrial pollution or untreated sewage. Additionally, climate change impacts like erratic rainfall patterns and rising temperatures can also contribute to soil degradation and loss of fertility.
The term used to describe the ability of soil to support plant growth is "soil fertility." Soil fertility refers to the soil's capacity to provide essential nutrients, moisture, and physical support for plant growth.
Soil fertility refers to the ability of soil to provide essential nutrients for plant growth, while soil productivity measures the capacity of soil to support plant growth and yield over a particular period of time. In other words, soil fertility focuses on the nutrient content of the soil, while soil productivity considers the overall ability of the soil to support plant growth.
The fertility of soil is determined by the presence of essential nutrients like nitrogen, phosphorus, and potassium, as well as other macronutrients and micronutrients. Organic matter, soil structure, pH level, and microbial activity also play key roles in soil fertility by supporting plant growth and crop productivity. Regular soil testing and proper management practices are essential for maintaining and improving soil fertility over time.
The difference between soil fertility and soil productivity is that soil fertility involves the soils and fertilizing them per the types of plants, crops, and soils, being used. The soil productivity has to do with the drainage of the soils, the amounts and types of fertilizers, and the progress of the plants and crops due to fertilization.
No, soil formation doesn't affect the fertility of soil but soil looses its fertility by being exhausted.

Pulses (legumes,beans,peas etc) enrich soil fertility. They have a symbiotic relationship with bacteria (rhizobia) and these are found in the root nodules of pulses. Members of the Rhizobium family fix nitrogen from the atmosphere to the soil and thus improve soil fertility.
