By repeating the vegetable cultivation test using thermal
decomposition liquid fertilizer various times with various
crop types, such as leafy vegetables and fruits (Fig. 7.22), it
was found that growth inhibition can be avoided by either
spreading thermal decomposition liquid fertilizer on the soil
and decomposing the organic acid before planting the crops
or fertilizing after the crops have taken root.
The thermal decomposition of water for agricultural use is
a new technology, and there are still many problems that
must be solved before it can be practically applied. However,
because organic waste can be converted into liquid fertilizer
quickly using just water, such conversion is an extremely
effective way to use organic waste in urbanized areas without contaminating the environment. In addition, because it
can detoxify dead or decayed plants, this technique is a
beneficial technology for developing countries that have a
shortage of fertilizer but may face environmental pollution
by organic waste.
