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.

Spermatogenesis, the sperm-making process, is a temperature-sensitive process which requires that the testicles be a few degrees cooler than core body temperature, with the normal core body temperature of the average bovine being approximately 101.5Â°F.f the testicles reach temperatures at or above this, the sperm-making process is disrupted, leading to the failure of the sperm to fully mature and may even cause them to die. The making of sperm is a process that can take anywhere from 45 to 60 days in bovines.
