Development of Trichoderma bio-organic fertilizers to ensure high yields and high quality of crops

Linkage of nature disease suppressive soil microbiota to soil microbiome manipulation

Summary: Effects of Trichoderma spp on promotion of plant growth and on biological control of soil borne diseases are much more significant than Bacillus spp. However, it is more difficult to make Trichoderma bioorganic fertilizers than Bacillus bioorganic fertilizers. The presentation introduces the steps of how to make Trichoderma bioorganic fertilizers. The functional mechanisms of Trichoderma spp will also be addressed in the presentation.

Prof SHEN is interested in the research of bioorganic fertilizers and soil microbiology. So far he has published more than 450 SCI papers and his H-index in Google scholar is 65. He is now the director of Academic Committee of Nanjing Agricultural University. He is a chief scientist of some national projects.

Summary: Banana production is now is severely hampered by Panama disease, a soil-borne wilt caused by the fungus Fusarium oxysporum f. sp. cubense race 4 (Foc4). We first compared soil microbiota in banana planting soils with different monoculture years to reveal the microbial characters associated with the increased disease. Then, the 6 disease suppressive soils were observed and the micobiota in these soils were analyzed to decipher the underlying mechanism involved in the disease suppression. At last, bio-organic fertilizer and its components were used in the high diseased soil to reveal the underlying mechanism involved in the recovery of disease suppression ability associated with the soil microbiota manipulation.

Rong LI, Associate Professor, Vice Dean of the College, College of Resources and Environmental Sciences, Nanjing Agricultural University. He focuses on the following research areas: agricultural waste disposal, organic fertilizer and bioorganic fertilizer development, and soil borne disease suppression. The main aim is to decipher the biological processes involved in the above topics. He published more than 40 SCI paper as first author of Corresponding author.
