Study on the cultivator (II)

A proposition of the method for comaring the effects of tines

Abstract

We investigated into the water permeability and structure of soils on the field, so that the physical properties of several cultivated soils may compare with these difference. The results obtained as follows.
1) The water permeability is a difference between the each treatment of soils.
2) The structure of difference is exclusivly shown on the surface of soils.
3) Then the water permeability is chiefly decided the physical properties of the thin layer on the soil surface.
4) We propose the comparative method for the effect of the cultivators tines. This method is standardzation, the properties of the thin layer on the soils, as above stated reason in the 1), 2), 3).
