An Agri-World (Agricultural World or Farming Planet) or α-class (alpha class) is one devoted to food production. The majority of its surface is given over to producing food for other worlds reliant on such imports - the food itself forms part of the planet's required tithe. Governors of such planets are required by the Adeptus Terra to protect the harvest and meet the quotas places on them. Often inter-commander rivalry leads to attempts to destroy or steal crops and livestock and then blaming them on pirates or raids.
Worlds with 850 parts per 1000 of the planet's surface covered with crop cultivation, hydroponics, animal fodder or animal husbandry are classed as Argi-Worlds. The population usually ranges from between 15,000 to 1,000,000 - which is widely spread across the planet. The tithe grade of such worlds range from Exactis Prima to Exactis Particular.

Masali, Quintarn and Tarentus form the group of planets called the 'Three Planets' in Ultramar, all of which are desert worlds. They are all classed as agri-worlds because of vast horticultural cities and moisture traps spread across the surface as well as bio-domes under which grow highly fertile forests. They are highly successful at producing vast amounts of food.
