Table 1. Yield and composition of fractions from soy bean meal as percentage dry weight.

Protein and lipid figures in percentage dry weight all others in percentage total lipid weight. Tlasinalogens are primarily ethanolamine phosphatides. 

Figure 4. Schematic of a section of a colony of A. wilsoni showing two major branches with associated sub-branching. Numbers represent total amathamides as percentage dry weight at each location. Pie charts represent the proportion of the major amathamides at the position indicated by the arrows. (Branch angles are schematic only.)...

Figure 2-60 shows a classification system developed by the Lower Mississippi Valley-Division, U.S. Corps of Engineers. Percentages are based on dry weight. A mixture with 50% or more clay is classified as clay with 80% or more silt, as silt and with 80% or more sand, as sand. A mixture with 40% clay and 40% sand is a sandy clay. A mixture with 25% clay and 65% silt is a clay-silt (see intersection of dashed lines in Figure 2-60).

Tables IV and VII give the percentage of the final frond number noted compared to the control for the same fractions as given in Tables I and II. The magnitude of the response in all cases is proportional to that noted on the basis of dried weight of fronds. The difference, where present, may be due to the size of the fronds since the effect of the phytochemical may be to limit frond size but not necessarily the number of fronds. Tables V, VI, and VIII give a description of the visual appearance of the fronds treated. Tables V and VI give the observations after 5 and 7 days, respectively, for the fraction from the sunflower, and Table VIII, for those from Jerusalem artichoke after 7 days.

Soybean nodulation. The results of this bioassay, shown in Table HI, are essentially the same as the dry matter production bioassay. Xanthlum root exudates reduced soybean nodule dry weight Glycine and Sesbanla root exudates reduced nodule, leaf and total dry weight. The percentage reduction is not quite as great as in the dry matter production bloassay.

Fig. 10. Effects of different HS samples at 20 and 200 mg L, used either alone or in combination with MH at 10 mg L, on the length and dry weight of primary root of V. faba seedlings. Data of HS and HS + MH treatments are expressed as the percentage of the variation observed with respect to the H20 treatment (C) and to the MH treatment, respectively.

The biomass of Tundra ecosystems gradually increases from 4-7 ton/ha for moss-lichen tundra to 28-29 ton/ha by dry weight for low-bush tundra. In the northern tundra, the plant biomass and dead organic matter are eventually shared. Southwards this percentage tends to diminish, and low-bush living biomass is smaller than dead plant remains mass. A typical feature of the Tundra ecosystems plant species is the prevalence of underground matter (roots) up to 70-80% of the total biomass. 

A 50- to 100-g sample of air-dried soil is placed in a drying can of known weight and placed in an oven at 105°C for 24 hours. It is removed and weighed and the percentage of moisture on a dry-weight basis determined using the following equation ...

In the method(s), petroleum constituents are extracted into a suitable solvent. Biogenic polar materials typically may be partially or completely removed with silica gel. The solvent is evaporated and the residue is weighed. This quantity is reported as a percentage of the total soil sample dry weight. These methods are better suited for heavy oil because they include an evaporation step.
