tilizer intake for some agricultural plants will influence
the health of growth of the plant itself. The flow of wa-
ter or fertilizer in the trunk or in the leaves capillary can
be investigated from the contrast of radiographic im-
age obtained from neutron radiography technique.The
growth of roots also dependent on the water content in
the soil

Furthermore, the size or health condition of sweet
potato or tapioca also much influences of the water
contains in the soil. Another root plants important for
herbs is ginseng. The quality of ginseng root relative to
the soil and fertilizer types also have been investigated
using neutron imaging technique.

Humidity of soils and capacity of soil retains wa-
ter is crucial for the farmer in selection of argriculture
soil. The adsorption characteristic for water can be
determined by imaging of the soils with simultaneusly
pouring water. The direction roots growth for the plants
usually under strong effects of water composed in the
soil. There is clearly shown that, roots prefer to extend
toward direction of high water content.
