Agriculture is a giant and complex system, and agricultural problems are closely related to the time and space information.Information agriculture is based on the soil characteristics of crop growth, adjust the input of crops.The promotion of precision agriculture can improve the productivity of the soil, with the least or the most savings to achieve the same income or higher income, and improve the environment.This paper mainly introduces the establishment of the model of variable rate fertilization of maize and the process of field operation in Changchun City, Jilin Province Nong'an County and combination of Geographic Information System and precision agriculture, save the input of chemical fertilizer, improve maize yield and efficiency.
