From the work on both the oil seeps and the oil spills, the phytoxicity of oil appears to be 

 high when it contacts foliage. Experiments are being planned for the summer of 1971 to further 

 study this process. 



The differences observed in the distribution of hydrocarbons between the wet and dry sites 

 indicates that the soil moisture level at the time of oil application may be an important factor. High 

 moisture levels apparently not only inhibit penetration of this oil into the soil but also allow for 

 considerable evaporation of the volatiles before they can come in contact with the root system. A 

 laboratay study is planned for the next growing season to further evaluate this factor.
