On the demand of precision agriculture of variable rate input technology, the homemade combined seed and fertilizer drill were successful manufactured. It could be accomplished sowing work prescribing by the application maps based on the GPS signal under the control of mechanical variable speed unit. We knew from the static and working testing that the control of variable rate fertilization was credible, the presented variable rate data was normal and the working condition of fertilization was satisfactory.
