Reduced need for fertilizers, pesticides, pH soil amendment, and water

Shortened harvest time for some crops & extended productivity for other crops

Extended shelf life of harvested crops, Improved coloration of flowers

Improved hydroponics and production of algae for fuel, etc.

Reclamation of waste water by removal of toxins

Animal husbandry:

Increased milk production in cows

More rapid growth and less food requirements for chickens. Increased egg laying
