Despite the increased rate of application, their cost remains higher compared to traditional engineering materials.
The strength of wood structural products depends on the rate of application and duration of the loads.
In Spain, there is a low rate of application of recycled aggregates in construction of road bases and sub-bases.
Both increasing the rate of application and using fertilizer containing more Cd lead to higher Cd concentrations in extracts for the field and the laboratory experiments.
The results indicate that combined use of FA and SS at a rational rate of application should not cause any significant effect on drainage water quality.
For both trials, the metal concentrations in soil extracts cannot be related to the Zn concentration in the fertilizer or the rate of application.
After a year of heavy dosages, the Department of Agriculture abruptly reduced the rate of application of heptachlor from two pounds to one and a quarter pounds per acre in 1959; later on, this was changed to half a pound per acre, applied in two treatments of a quarter of a pound each, three to six months apart.
Chemical tests of soil, plant, or both are used to determine fertilizer needs, and the rate of application is usually based on the fertility of the soil, the cropping system employed, the kind of vegetable to be grown, and the financial return that might be expected from the crop.
Increasing the strain rate of application, we overcame key skin variability, achieving increases in both projection penetration depth (by over 50% length) and area coverage of a full array (from 50% to 100%).
Although often used, open-flow plethysmography is complicated by the time-decay of pressure signals generated in the open chamber (e.g. equivalent volume displacements will yield different pressure pulse magnitudes depending upon the rate of application, dP/dt).
Fresh OW amendment significantly increased the amount of MCPA leached (from 13.7% in the most alkaline soil to 36.7% in the most acidic, at the 5% rate of application), favored by the higher levels of water soluble organic carbon content.
