Agra Tech also offers The Agra Tunnel , which is an inexpensive field of battle back design to shield study harvest from sun , malarkey and frost damage .
Ecology
July 2009 marked the opening of the Omega Center For Sustainable Living ( OCSL ) education center and natural waste water treatment adroitness in central New York . Its centerpiece is a 4,500 - square - foot greenhouse that accommodates a piss handling system forebode an Eco Machine . The scheme use plant , alga and other materials to recycle OCSL ’s waste water into clean water . The construct is that of the eminent life scientist , Dr. John Todd and his company , John Todd Ecological Design .
