Abstract :In this pot experiment, poultry manure dried by Fan separator was applied at different rates N to see the effect of poul-try manure on the growth and total N uptake of corn and rice. Contribitions of poultry manure to A-values insert ignore into journalissuearticles values(available N); of soils, %NdfF insert ignore into journalissuearticles values(N-fertilizer);, %NdfPM insert ignore into journalissuearticles values(poultry manure);, nitrogen recovery percent of poultry manure and the quantity of poultry manure equivalent to 1 kg insert ignore into journalissuearticles values(NH 4 ); 2 SO 4 were determined by 15 N trace technique. The results are summarized as follows: 1. Increasing rates N of poultry manure significantly increased the amount of corn straw, rice grain+straw and total N uptake of corn and rice plants. 2. The contribution of poultry manure to A-value insert ignore into journalissuearticles values(available N); of soils was significant. Increasing rates of poultry manure increased the A-values from 66.19 to 186.70 mg N/kg soil in soil where corn was grown, and from 208.59 to 382.14 mg N/kg soil in soil where rice was grown. 3. Increasing rates N of poultry manure decreased the percentage of nitrogen derived from insert ignore into journalissuearticles values(NH 4 ); 2 SO 4 labelled with 15 N insert ignore into journalissuearticles values(%NdfF); in total N uptake of corn and rice, whereas the percent nitrogen derived from poultry manure insert ignore into journalissuearticles values(%NdfPM); increased from 14.24% to 47.87% in corn and from 9.19% to 33.54% in rice. 4. Maximum nitrogen recovery percentage obtained from poultry manure was about 4.61 for corn and 4.13 for rice. 5. It was found that, 1 kg N as insert ignore into journalissuearticles values(NH 4 ); 2 SO 4 was equivalent to 7.74 kg N as poultry manure in soil where corn was grown, and to 9.65 kg N as poultry manure in soil where rice was grown. Those results show that 1 kg insert ignore into journalissuearticles values(NH 4 ); 2 SO 4 is equivalent to 50 kg poultry manure dried by Fan separator containing 3.13 % N for corn plant, and to 62 kg poultry manure for rice plant.
