Cumulative mass of soil retained
Webb) Shake and agitate the stack of sieves until all soil grains are retained on the finest sized sieve through which they can possibly pass; c) Weigh the mass of soil M i retained on each sieve. d) For each sieve size used, compute N i, the percentage by mass of the soil sample that is finer than the ith sieve size. For example: N i = (1/M 0) Σ M j WebOther field tests during the period from 1923 to 1928 indicated that the effect of light could not be dissociated from the nutrition of the seedlings. The availability of nitrogen is changed when the tempera- ture of the soil is raised by thinning of the canopy. The severance of the tree roots when the trees are cut changes the soil biology.
