interpreting plans and drawings Flashcards
(25 cards)
is necessary so that a map can be drawn of the property‘s topography, boundaries, soils, water resources and so on, and a farm business plan can be formulated.
site assessment
is a system of growing crops in linear pattern in at least one direction rather than planting without any distinct arrangement
row planting
are planted in rows or straight lines, either singly or in multiple rows,
mainly to enhance maximum yields as well as for convenience.
crops
are either arranged in equidistant single rows or in
multiple rows.
row-planted crops
Planting in single rows is most common in ____________ or _____________, the growing of a single crop.
monocropping or sole cropping
systematic apportioning of the farm area or any growing surface for crop production. In multiple cropping by intercropping,
spatial arrangement
system of growing crops in blocks or strips of 2 or more rows
multiple row
two or more crops are grown in the same piece of land.
multiple cropping
used to refer to the practice of replanting an already established plant in one location and moving it elsewhere.
transplanting
is most common with small-seeded vegetables,
transplanting
commonly used to refer to the planting of seedpieces or underground vegetative planting materials directly into the soil.
direct seeding
field shape must be accurately drawn showing pertinent
obstructions, features and elevation details.
topographic data
water supply must be clearly indicatedshowing location and available capacity.
water aource capacity
soil and crop limitations must be accounted for to reduce runoff and deep percolation by mismanagement of the irrigation system.
soil and crop characteristics
soil water holding capacity, maximum application rate and climatic data must be used to select the correct irrigation system design.
design parameters
the nozzle selected, operating pressure, discharge rate and sprinkler spacing must all be shown on the plan. The irrigation interval, set time, application rate and net amount applied must also be calculated.
design data
Longitudinal slopes should be almost same as for the furrow irrigation.
strip slope
Cross slopes must be eliminated by leveling.
strip width
Levees should be big enough to withstand erosion, and of sufficient height to contain the irrigation stream.
construction of Leeves
maximum advance stream used should be non-erosive and therefore depends on the protection afforded by the crop cover.
selection of the advanced stream
The ideal lengths can be obtained by field tests.
the length of the strip
conveys water through pipes and applies it with a minimum
amount of losses.
sprinkler system
The laterals, mains, sub-mains and the pumping plant are all portable
fully portable system
Water source and pumping plant are fixed in locations.
Other components can be moved.
semi-portable system
