Study Notes
Farm Power
- Farm power is required for two kinds of work: tractive work (pulling/drawing effort) and stationary work.
- Tractive work includes land preparation, cultivation, harvesting, and transportation.
- Stationary work includes threshing, irrigation pumping, and feed grinding.
Sources of Agricultural Power
- Human power technology: uses human energy, with a mature human developing an output of 0.1 hp.
- Animal power technology: uses animal energy, with draft animals like horses and buffaloes developing an output of 0.7-1.3 hp.
- Engine power technology: uses heat energy from fuels to produce mechanical energy, with outputs ranging from 3 hp to over 200 hp.
Other Sources of Farm Power
- Electric motor: suitable for machines requiring 5-7.5 hp or less, with advantages including reasonable cost, long life, and reliability.
- Water: can be used to drive agricultural and industrial equipment, with energy derived from potential/kinetic energy.
- Wind: can be used to drive farm equipment, but has an intermittent and fluctuating nature.
- Solar: can be used to drive pumps, heat air/products, and generate electricity with solar cells.
- Biogas: a type of biofuel produced from organic waste decomposition, primarily consisting of methane and carbon dioxide gases.
Agricultural Machinery and Equipment
- Land preparation machinery: includes plowing, harrowing, and leveling.
- Crop establishment machinery: includes seeding, planting, and transplanting.
- Crop care machinery: includes irrigation, fertilization, and pest control.
- Harvesting and threshing machinery: includes reaping, binding, and threshing.
- Drying machinery: includes grain dryers and crop dryers.
- Milling machinery: includes grinders, crushers, and flour mills.
