Study Notes
Agricultural Engineering and Related Concepts
- Bulk density of rice husk ranges between 50-80 kg/m³.
- The downward bend of the share point in a plow is referred to as the tilt angle.
- A hill-drop planter is designed specifically to place seedlings in both rows and hills.
- A reaper-windrower is a machine that cuts standing crops and arranges them neatly for collection.
- The theoretical field capacity for a 4-ha field plowed with a three-bottom 12-inch tractor-mounted moldboard plow over 11 hours at a speed of 5 kph is calculated to be 1.13 ha/hr.
- Tillage involves the mechanical manipulation of soil for various agricultural purposes.
- The draft of a plow depends on the size of the plow, plowing depth, and type of soil.
- The ground wheel of a planter is crucially connected to its metering device for properly dispensing seeds.
- For a two-row corn planter, the expected hill spacing can be derived from the given specifications, with options including 0.62 m and 0.81 m.
- Twelve man-days are equivalent to three men working for three days.
Agricultural Engineering Regulations
- The Institutionalization of Agricultural Engineering Profession in Local Government Units is outlined in Memorandum Circular No. 2008 167.
- AMMDA stands for Agricultural Machinery Manufacturer’s and Distributors Association.
Commodity Market Structures
- Monopolized commodities usually have one seller controlling the supply, while oligopolized markets have a small number of sellers.
- Pure competition is characterized by many sellers providing indistinguishable products, as seen with peanuts and cashew nuts.
Water Resources Management
- The maximum flow of water at any depth is best achieved with a trapezoidal canal cross-section.
- Laminar flow is defined as having a Reynolds number of less than 1.
- The highest approximate residence time for water is found in deep groundwater.
Soil and Erosion
- Splash erosion occurs with thin films of soil detached and transported by flowing water.
- The critical flow condition is met when Fr = 1.
- Soil properties that indicate water transmission ability or moisture content are crucial for understanding irrigation practices.
Agricultural Engines and Machinery
- Black smoke from an engine often indicates poor combustion or a fuel problem, while starting issues can be due to battery failure or fuel supply.
- Familiarity with post-harvest machinery operations, such as calculating milling recovery and hulling coefficients, is essential.
- Understanding the terms related to warranty, after sales, performance test, and machine specifications is vital in agricultural equipment management.
Agricultural Hydraulic Systems
- Compute design discharge requirements and efficiencies in irrigation canals while considering evapotranspiration and percolation losses.
- The power rating of pumps must be calculated based on discharge rates and the efficiencies of pump systems.
Power and Energy in Agriculture
- Understanding energy transfer in agricultural systems, such as how rotational movement is converted to electricity in aerogenerators, is integral for sustainable practices.
Miscellaneous Agricultural Practices
- Awareness of definitions like effluent streams, influent streams, and perennial streams is needed for efficient water management in agriculture.
- The value of different crops, their market control, and pricing strategies are critical for maximizing profits in agriculture.
