industrial manufacture of inulin in Belgium, France and Netherlands; Sigma makes it from both …

At field capacity, air permeability was measured, utilizing undisturbed soil samples for 0-8
cm depth and using double copper rings for 1-5 cm depth, on a polder soil (clay) and two silt …

Nearly 700 determinations, all in duplicate show that the best results are obtained when the
minimal diameter of the aggregates is 2.0 mm, the sample is first wetted and then incubated …

The modulus of rupture (S) can be calculated from 2F the equation S= 2F/DL, where F= the

A useful index of soil structure may be obtained by multiplying the "swellable drainage pores"
([total pore volume - volume percentage of moisture at field capacity] X [swelling factor - …

In the old region of the sea-polders, on 5 soil types differentiated by the thickness of the clay
layer and the depth at which natural drainage appears, variations in root and sugar yield …

Sampling for the determination of pore-size distribution is done by means of two copper rings
(7.7 cm diameter, 2 cm height) pushed simultaneously into the soil, one above the other, to …
