These positions are often found in universities and research labs. The agricultural jobs may include improving farm equipment technology to increase the quantity and quality of goods, finding cures for diseases that affect livestock and crops, and discovering more effective methods of pest control. A strong background in science, math, and engineering is necessary for this position.Farming was likely the very first agriculture job; in addition to crops and livestock, it may also involve specialized animal breeding. To ensure healthy crops, the art of plowing, planting, and fertilization must be learned for each crop type. The responsible use of pesticides is also important, as well as the routine maintenance of facilities and equipment. A production manager may be employed to oversee progress, while also finding ways to increase production using less time and money. Many farm positions are seasonal, employing extra workers during certain months to pick fruits and vegetables.Animal breeders must be well educated in animal health and genetics. They must know the proper foods to feed an animal for ensuring healthy offspring, and will study the various traits of different animals to determine the best breeding specimens. Breeders will often use artificial insemination and must therefore understand how the procedure works.
