In-Depth Information
there are a quite strong correlation dependence between the organics content in soil and
moisture of this one, so moisture is generally retained in organic components of soil,
but soil mineral ones don't absorb water (Fig. 5a);
water makes changes in the reflection, and there is especially significant increased light
scattering by soil particles in the visible spectrum, so a brightness coefficient falls
slowly, but soil becomes darker if the water content increases (Fig. 5b);

the ferric oxide content in soil considerably influences on reflection coefficients, so that
there is the absorption with minimum energy in the range of 570-660 nm, but an
absorption effect goes up if the organics content is more than 2 % (Fig. 6a,b);
