Midterm Flashcards
It is the evapotranspiration that would happen on a surface when the moisture supply is not limiting.
POTENTIAL EVAPOTRANSPIRATION
It is the ET that occurs when the ground is completely shaded by actively growing vegetation and where there is no limitation in the soil moisture
POTENTIAL EVAPOTRANSPIRATION
It is the process of applying controlled amounts of water to plants at needed intervals.
IRRIGATION
It describes the resistance of vapor to flow through stomata openings, total leaf area, and soil surface.
SURFACE RESISTANCE
It describes the resistance from the vegetation upward and involves friction from air flowing over vegetative surfaces.
AERODYNAMIC RESISTANCE
It is the process of applying water to crops by flooding an entire field or section of land.
SURFACE IRRIGATION
It is the amount of heat required to convert a unit mass of a liquid into vapor without a change in temperature.
LATENT HEAT OF VAPORIZATION
It describes the physical features of an area of land which includes elevation and slope.
TOPOGRAPHY
It is the benchmark used for evaporation rate where crops have a fixed crop height of 12 cm, albedo of 23%, and surface resistance of 69 s/m.
HYPOTHETICAL REFERENCE CROP
It is the amount of water that is required by a crop during its growth cycle.
CROP WATER NEEDS
It is the measure of the effectiveness of an irrigation system in delivering water to crops which depends on soil type
IRRIGATION EFFICIENCY

F
T/F Surface irrigation requires more capital cost
F
T/F Irrigation is only used for agricultural purposes
F
T/F Surface irrigation is the most efficient type of irrigation
