Machinery and Integrated Cropping - Essay Example

Potato residues are in small amounts, and add very little organic matter in the soils. However, sweet corn adds more refuse that is decomposed by the forage. It also consumes phenoxy herbicides and act as a pest control measure. The rotation provided uses crops with a different nutrient portion to maintain fertility and recovery. Rotation schemes should factor in the cost of production, economic gains and long-term disease and pest control measures to manage potato production. Rotation farming in large tracks of land requires adequate and modern equipment to reduce the cost of labor cost and time.

Due to the intense and time-consuming procedures involved, it is important to use zero-tillage. Specifically, this entails the use of 45hp tractor that cultivates at a rate of 1 acre/hr. (Nutbey, 2010, p 26). Notably, the purpose of this machine is to pull equipment such as Rotavators, planters, cultivators, digger elevators and harrows. However, the farmer must decide whether to buy or hire the 45hp tractor. The net present value method of analysis helps the farmer to determine whether to buy or hire this equipment.

Net Present Value is a method of analysis that gives an answer to this dilemma. Precisely, it adopts the dollar as the base of this calculation and assumes the formula {PVF= 1/ (1+i) n}, where ‘i’ is the rate of discount and ‘n’ is the number of years (Gollier, 2010, p 17). The data represent the monetary pros and cons of hiring and purchasing, and shows buying as the best option. The purchase Net Present Value is $10,696 less than the annual hire Net Present Value. Therefore, it is profitable to buy than to hire the tractor.

Drought resistant crops are grown in arable lands. For this reason, the 200ha arable land can be used to grow wheat, barley, sugar beet, and the grass under rotational farming. Wheat farming will serve as animal feed and human food. I thus recommend
