A research investigation was undertaken to determine the rate of movement of selected inhibitors in various soils. Most of the research dealt with soluble phosphates. The use of chromates as soil additives was not considered feasible because of the toxicity of chromates, and silicates were not as effective as phosphate in inhibiting stress-corrosion cracking. The investigation consisted of the following four parts: A brief literature survey on the movement of phosphates in soils A laboratory investigation of the horizontal movement of phosphates and silicates in selected soils A limited field...

The investigation consisted of the following four parts: A brief literature survey on the movement of phosphates in soils A laboratory investigation of the horizontal movement of phosphates and silicates in selected soils A limited field study of the downward movement of phosphates in a clay soil A laboratory investigation of the downward movement of phosphates in various soils.
