The effect of application rate of pig or chicken manure on the seasonal change of tomato(Minicarol) rhizosphere microflora was investigated by field experiment were surface soil(16cm) mixed with manures 1 weeks before transplanting. 1. Rhizobacteria population of control plot decreased 5 weeks after transplanting(WAT) than 1 WAT and 1.5~2 times higher colony counting was found in DNB(Diluted nutrient broth medium) than NB(Nutrient broth medium) at 15 WAT. 2. Rhizobacteria population at 1 WAT inereased in NB medium with the application rate of both manures but decreased in DNB with chicken manure. Colony counting in NB of 60 and 120 mg/ha treatment was 100 times higher than that of the control. However, rhizobacteria in DNB at 15 WAT(harvest stage) was much higher than that of NB. 3. Application rate did not affect fungi population 1 WAT in pig manure but decresed in chicken manure. At 15 WAT fungi population was 2 times higher than 1 WAT with chieken manure and highest in 30 mg/ha but with pig manure decreased with rate than the control. 4. Actinomycetes population at 1WAT was not different among pig manure rates and decreased with chicken manure than control. At 15 WAT population increased in all manure rates. especially in 10 mg/ha pig manure and 30 mg/ha chicken manure 4 times that 1 WAT.

This research was carried out to determine the quantity and characteristics of layer excreta produced in different age and different types of layer house. Daily feed intakes in the growing stage were 60.8 and 92.9g/d the 6th and 12th week of age, respectively. Daily feed intakes in the early laying stage (19th wk of age) and the ending period of laying(55th wk of age) were 105.1 and 122.0 g/d, respectively. A laying hen consumed 193.1~222.5$m\ell$ of water per day. The amount of excreta produced by laying hen were 143.3~144.8g per day. The moisture contents of excreta produced by laying hen ranged over 74.7~80.5% in laying period. The average contents of N, $P_2O_5$ and $K_2O$ in layer excreta were 4.88, 1.92 and 1.71% in DM basis, respectively. In the laying period, CaO contents of excreta were 7.42~9.02%. The moisture contents of excreta produced by windowless poultry house, open-sided poultry house applied mechanical ventilation and open-sided poultry house applied natural ventilation were 65.4, 75.7 and 81.3% in summer, respectively.

This study was carried out to investigate the chemical characteristics of different organic liquid fertilizer during fermentation at plastic house in Chungbuk Agricultural Research and Extension Service. Chicken dung, soybean meal, and rice bran were used for nutrient sources. The obtained results from this study were summarized as follows; Total nitrogen contained the highest in soybean meal as 55 mg·kg^-1, and phosphate and potassium contained high in chicken dung and rice bran in organic liquid fertilizer materials. The pH of chicken dung was near 7.0, that of soybean meal and rice bran indicated acidity(pH 3.8~4.4). The electrical conductivity of chicken dung consistently increased during fermentation, and that of soybean meal and rice bran increased and decreased early season and increased at late incubation period. Hydrogen sulfide gas occurrence of chicken dung was 3,200 mg·L^-1 at early season and 1,600 mg·L^-1 at late incubation period, and that of soybean meal and rice bran treatments were not or very low concentration of hydrogen sulfide gas during manufacturing period. The nitrogen and calcium content of organic liquid fertilizer were the higher in chicken dung and soybean meal than rice bran. The phosphate and magnesium content of rice bran was the high as 5.6 g·kg^-1 and 1.5 g·kg^-1, respectively. There was no difference in potassium content among the different liquid fertilizers during fermentation.
