In the latest years, a disease epidemy of Moler caused by Fusarium oxysporum f.sp. cepae have just occurred in Brebes Central Java. The disease intensity however is variation between the shallot production lands. Some lands show suppressive with disease intensity lower than 5% and some the others are conducive with disease intensity over 50%. It is interesting that in Brebes occur suppressive and conducive soil to moler disease. It is possible that the suppressiveness is determined by environmental condition including chemical soil characters. This paper reports chemical character of suppressive and conducive soil to moler disease in Brebes. The evident shows that the suppressive soil is more fertile than those conducive one. The suppressive soil is chemical characterized by significant higher organic mineral, C-organic, Pavailable, K-exchangeable, and Cation Exchange Capacity than those conducive one.
