  1. NEM (Policy) – Irrigation Irrigation is the application of water to land for the purpose of sustained production. In arid regions, irrigation provides the majority of crop water needs. (up to 30+ inches) In humid areas it is to supplement rainfall for withstanding drought or to ensure crop productivity. (6-12 inches in NC)

  9. A very informative guide with many useful NC soil, climate, and crop specific tables. The Guide provides general planning, design, and management guidance on various methods of irrigation commonly used in NC. Extended periods of no rain (< 0.1”/day) that exceed 30 days have been noted in most NC rain gauge stations that have at least 50 years of data.
