Center for development of environmental-friendly agriculture food products using red clay
Ⅱ. Comparison of Objectives and Result
1. Production yield of available SiO2 from red clay
Ÿ Objective : 80%
Ÿ Result : 90.08%
2. Milling technology of RCPM
Ÿ Objective : average particle size of 200nm
Ÿ Result : Processing into micro-size was determined because micro-size is excellent in yield
and economical feasibility than nano-size
3. Fertilizer efficacy of RCPM
Ÿ Objective : 15% increase in quantity than commercial silicate fertilizer
Ÿ Result : 31.7% increase in cucumber quantity
4. Pesticide efficacy of RCPM
Ÿ Objective : 50% efficacy of commercial pesticide
Ÿ Result : the rice blast control of 63.4%
5. Technology for increasing the yield of eel
Ÿ Objective : Above 15%
Ÿ Result : 19% increase when added in eel feed
6. Technology for decreasing the motality of juvenile eel
Ÿ Objective : Below 5%
Ÿ Result : Survival rate of 95% (Control : 81.7%)
7. Technological development of functional fertilizer evaluation and agricultural application of
red clay processed nano material
Ÿ Objective : To measure the basic growth, physiological characteristics and fertilizer
condition optimization for crops such as radish, cabbage, and various fruits (tomatoes,
cucumber, watermelon etc.) with the application of red clay processed nano material
Ÿ Result: Application of RCPM fertilizer to individual crops was as follows: Radish – 0.5 kg
fertilizer per square meter was used once every 2 weeks (total twice). Cabbage – was
treated with 2000 ppm once every 2 weeks (total 3 times). Tomato – 200 times dilution
once per week (total 4 times). Cucumber: 1000 fold dilution once per week (total 4 times).
Each crop was analyzed for the following parameters to determine the effect of RCPM –
photopigment content analysis, photosynthesis, chlorophyll fluorescence efficiency, ascorbic
acid content, fruit water content, reducing sugars as well as brix degree. The results
obtained for the crops were as follows: radish and cabbage growth and development were
promoted, tomato growth, development and yield improved with fruit cracking decreased,
cucumber growth, development and yield improved along with fruit bending decreasing.
Overall, crop growth and development improved with existing silicate fertilizer treatment.
8. Horticulture and agricultural fertilizer of special crops application of red clay processed
Ÿ Objective : To investigate the cultivation application of functional fertilizer on the growth
and physiological characterization of special crops for the development of agricultural
production techniques and improvement of functional composite fertilizer on special crops.
Ÿ Result : Excellent growth and development was observed in 1000 fold dilution of RCPM
application. Saponin content was highest at 1000 fold dilution treatments; when dealing
with rice husks and 1000 fold dilution with RCPM, growth and development were promoted
along with saponin content in ginseng.
9. Development of agricultural methods through research of inhibitory effects of RCPM on
plant pathogens in soil.
Ÿ Objective : In vitro evaluation of RCRM on growth inhibition of soil borne plant
pathogens and development of environmentally friendly agricultural method for plant
disease control to prevent soil-borne crop diseases by using RCPM (efficacy of RCPM over
50% compared to chemical pesticide).
Ÿ Result : Efficay of RCPM at 53% against clubroot of chinese cabbage. Antimicrobial ativity
against 3 bacterial and 5 fungal plant pathogens. Determination of concentration and time
of RPM for the control of each detrimental microorganisms in soil.
10. Development of agricultural applications for enhancing freshness of cultivated vegetables.
Ÿ Objective : Determination of the mechanisms involved in antimicrobial effects of RCPM
and optimization of agricultural techniques using RCPM to control various pathogenic
diseases for each crop cultivation.
Ÿ Result : Determination of the pathway for inhibitory effect of RCPM on plant pathogens,
Guideline of 2 agricultural techniques using RCPM for activation of effective
microorganisms. Guideline of 4 agricultural techniques (with efficacy against plant
pathogenesis) using RCPM mixed with chemical pesticide to control clubroot of chinese
cabbage (286%), black spot disease of chinese cabbage (101%), Colletotrichum
gloeosporioides (99%), and bakanae disease (98%).
