Prime Farmland (P): Irrigated land with the best combination of physical and chemical
features able to sustain long term production of agricultural crops.
This land has the soil quality, growing season, and moisture supply
needed to produce sustained high yields. Land must have been used for
production of irrigated crops at some time during the four years prior
to the mapping date.
Farmland of Statewide Importance (S): Irrigated land similar to Prime Farmland that has a good combination of
physical and chemical characteristics for the production of agricultural
crops. This land has minor shortcomings, such as greater slopes or less
ability to store soil moisture than Prime Farmland. Land must have been
used for production of irrigated crops at some time during the four
years prior to the mapping date.
