  2. Soil fertility - Wikipedia

    en.wikipedia.org/wiki/Soil_fertility

    Phosphorus is a primary factor of soil fertility as it is an element of plant nutrients in the soil. It is essential for cell division and plant development, especially in seedlings and young plants. [10] However, phosphorus is becoming increasingly harder to find and its reserves are starting to be depleted due to the excessive use as a ...
