- Land capability (classification)
- The quality of soil resources for agricultural use is commonly expressed as land capability classes and subclasses, which show, in a general way, the suitability of soils for most kinds of field crops. Soils are grouped according to their limitations when they are used to grow field crops, the risk of damage when they are used, and the way they respond to treatment. Capability classes, the broadest groups, are designated by Roman numerals I through VIII, with I being the best soils and VIII being the poorest.
- Land grant university
- The term used to identify a public university in each state that was originally established as a land grant college of agriculture pursuant to the Morrill Act of 1862. In most states the original agricultural colleges grew over time into full-fledged public universities by adding other colleges (e.g., arts and sciences, medicine, law, etc.); in states where a public university existed prior to 1862, the first Morrill Act resulted in a college of agriculture being added to the university. USDA funds go only to the original land grant colleges of agriculture within the so-called land grant universities.
