Crop economic importance (World Economic Crops)
was grouped into five broad use classifications to allow rapid electronic
access to economically important crops. The five searchable uses are described
- Food – Cereal, fruit, nut, vegetable, pulse,
juice, sugar, starch, bee plants, oil, beverage base, and additives for flavor,
color, thickening, emulsification and other food for human consumption.
- Animal Food – Animal food or feed including forage, fodder, and bird feed.
- Medicinal – Plants containing chemically or
medically active substances such as medicines, pharmaceuticals, folk remedies,
poisons, and pesticides.
- Material – Fiber, timber, gums, resins, latex,
oils, dyestuffs, tannin, lipids, and wax.
- Fuel – Rapidly growing plants for energy
production, petroleum substitutes, and industrial oil.
Specific economic importance information, including uses
with negative economic impact such as invasiveness, remain in the database and
are displayed on individual crop information pages.
Metric-English Unit Conversions
Temperature and rainfall are commonly reported in both
Metric and English units. Conversion of temperature between metric (°C)
and English (°F) units is by the following equations:
°F = (EC – 32)/1.8
°C = °F * 1.8 + 32
Conversion of rainfall from metric (millimeters) to English
(inches) is by the following equations:
in. = mm/25.4
mm = in. * 25.4
