The fertility of soil is determined by the capacity of the soil to sustain the life of plants by supplying the required nutrients. Soil rich in nutrients is said to be fertile, while soil deficient in nutrients is said to be infertile. The quality of soil is determined by the amounts of humus present in it. Humus makes the soil porous. So, water and air can easily go deep inside the soil
Soil has been used for agricultural purposes since ancient times. But, there are some agricultural practices which deprive the soil of its nutrients. For example, growing the same crop in the same soil repeatedly for years (known as mono culture) reduces soil fertility. This is because the crop draws nutrients from the soil, and growing it repeatedly makes the soil deficient in these nutrients. The infertility of soil caused by mono culture can be avoided by adopting the following methods.
Which of the following are correct : (a) The fertility of soil is determined by the capacity of the soil to sustain the life of plants by supplying the required nutrients. (b) Soil rich in nutrients is said to be fertile, while soil deficient in nutrients is said to be infertile. | |||
