Konkuk University, Seoul · October 5–7, 2016

Natural Science Farming Symposium 2016

A day of talks in Seoul, then two days on the farms. 23 talks, three languages. Master Cho's students from ten countries showed what natural farming did on their fields, from Afghan potatoes to Hawaiian macadamias. Every talk is translated, checked line by line, and boiled down to what was tested and what happened.

Feeding the Good Bacteria Cut Pepper Root Rot to 6%

A Konkuk plant pathologist, new to natural farming, reviews biological control of soil-borne disease and shows his own work: bacteria coated on rice seed against seedling rot, and bacteria against Phytophthora root rot of pepper, both working better when given a sugar the bacteria can use and the pathogen cannot. He then gives first, unreplicated microbe counts from the Paju natural farming soils and from each IMO step: counts fell about tenfold from IMO1 to IMO4 and the fungi shifted from Aspergillus to Rhizopus. He draws no conclusion about natural farming yet.

Found Pepper root rot: 81% with the pathogen alone, 22% with bacterium KJIR5, 6% with KJIR5 plus arabinose
