This study was carried out to survey the distribution of farm-yard manure by analysis 355 samples collected from major flue-cured and burley tobacco area. The applied manure amount for flue-cured and burley tobacco were 1,500 kg and 1,600 - 2,000 kg per l0a, respectively. The major raw materials of farm-yard manure were cattle dung, chaff, and rice straw. The main manure used for tobacco plant were cattle dung+chaff, cattle dung+rice straw+chaff, cattle dung+rice straw, and poultry dung+chaff, which were mostly unfinished fermentation materials. The chemical characteristics of farm-yard manure were as follows: pH for 87% of samples was higher than 7.1, total nitrogen for 70% of samples was 0.51-1.50%, P$_2$O$_{5}$ for 48% of samples was higher than 1 %, $K_2$O and CaO were 1-2%, MgO was 0.5-1.0%, and Cl was lower than 0.5% level. In general, the manure used for tobacco cultivation was higher contents of chemical components than that of manure made by rice straw. Also, the concentration of chemical compounds in the samples collected from burley tobacco area were higher than that of flue-cured tobacco districts.s.
