Computerized control of the environment over small-enclosed parcels of land is known as “Controlled Environment Agriculture” (CEA). CEA technology, as it exists today in the US, Europe and Japan, provides an excellent stage for the introduction of nanotechnology into plant production agriculture. With many of the monitoring and control systems already in place, nanotechnological devices for CEA that provide “scouting” capabilities could tremendously improve the grower’s ability to determine the best time of harvest for the crop, the health of the crop and questions of food security such as microbial or chemical contamination of the crop.
