weight is the weight of the sand from -1 added to the 0 phi weight of sand. So 2.95 + 4.95 = 7.90, and the 1 phi cumulative weight is 7.90 + 13.36 = 21.26, etc. Weight percent is the total weight of Sieve Fraction Divided into each weight of the sand fractions. Thus for -1 phi 2.95 is divided by 33.42 then times 100 = 8.83 %.

Next thing to do is to find whether 50% of the coarse-grained (which is 46-46.5% of the soil sample) is passing in sieve #4, and upon checking graph 1 the percent passing at sieve #4 is 100%, hence the soil is classified as sands. Then, the percent of fines has to be checked by looking again the percent passing at sieve #200 which is 7-8% which ...

In Ethiopia, soil degradation and nutrient depletion have gradually increased [6] in which the annual nutrient deficit of N, P and K is -41, -6 and -26 kg ha-1. yr ,respectively with 2 to 3% of productivity decline per year [7]. One of the major constraints to retaining soil fertility in Ethiopia is the failure to return crop residues and

Sieve Analysis Overview Sieve analysis is a technique used to determine the particle size distribution of a powder. This method is performed by sifting a powder sample through a stack of wire mesh sieves, separating it into discrete size ranges. A sieve shaker is used to vibrate the sieve stack for a specific period of time.
