Disease-inducing Soils

Disease-inducing soils are soils where the percentage of fusarium, with filamentous bacteria, in the soil is high (over 15% to 20%).  When living organisms with a high content of nitrogen applied as manure, odors are given off, maggots appear and a variety of harmful insects swarm.  Since insects frequently appear, manure application with living organisms become harmful.  More than 90% of soils today comprice the putrescent type; inorganic nutrients become insoluble, the soil is hard and physically poor.  In rice fields, methane gas emission is high.
