Design of variable rate fertilizer applicator


Design of variable rate fertilizer applicator



Nongye Jixie Xuebao = Transactions of the Chinese Society of Agricultural Machinery 36(1): 50-53



The variable rate fertilizer applicators by hand controlling (VFAH) and that by automatic controlling (VFAA) are investigated, under the consideration to practice the idea of precision agriculture (PA) progressively in China. The working principle and key components of the VFAH are set forth. Experiments show that the adjustment of the VFAH is convenient and its performance is steady. At last, a kind of VFAA that can satisfy the requirement of PA is introduced.
