What type of soil is characterized as being rich in nutrients?

Fertile soil is characterized by its high nutrient content, which supports healthy plant growth and agriculture. This type of soil typically has a good balance of essential nutrients such as nitrogen, phosphorus, and potassium, as well as organic matter that aids in water retention and soil structure. Fertile soils are usually found in regions with a combination of factors such as adequate rainfall, diverse vegetation decay, or specific geological processes that enrich the soil over time. These characteristics make fertile soil ideal for gardening and farming, as it promotes robust crop yields and biodiversity. Other types of soil mentioned, such as arid, saline, and infertile soils, do not have the same nutrient richness required for optimal plant growth.
