Sixteen chemical elements are important in which carbon, hydrogen, and oxygen are supplied by air and water, which comprise about 98% of the fresh weight of the plant, at least 13 other chemical elements, called the essential inorganic nutrients, are needed for plant's growth and survival.he inorganic material obtained from soil which are used as raw material by plants are called mineral nutrients. Absorption utilization and assimilation of inorganic compound or minerals by plants for synthesis of essential material for their growth, development, structure and physiology is called mineral nutrition.

One of the limiting factors to sperm production is size of the stallions testicles. The testicles of young stallions have not fully developed. As a result, they are not yet able to produce sperm in the quantity per day that they will when they are a fully developed stallion. Less available sperm production equates to fewer ejaculations in order to maintain the normal fertility of 3,000,000,000 sperm per ejaculation.
