The Effect Of Oil Well Brines On Agricultural Fields And Water, V. P. Evangelou, M. Marsi, Kenneth L. Wells

Agronomy Notes

What is Brine and Where Does it Come From?
Brine is the salty water trapped in rock formations associated with oil and gas deposits. It consists mostly of sodium chloride but can also contain other things such as organics, bromide, some heavy metals and boron. Its source as a pollutant is usually oil stripper wells which produce less than 10 barrels of oil per day with typically a 10:1 ratio of brine to oil. Such wells are distributed throughout Kentucky and are often located on farmland. In some cases, brine rises to the land surface even where no oil wells …

Burley tobacco has been used every year at Lexington, for 4 years at Eden Shale farm in Owen county, and 1 year in McCracken county, while dark air-cured tobacco was used for 4 years at the Western Kentucky Substation, Princeton.

Fertilizer-Insecticide Mixtures On Tobacco Plant Beds And Fields, George D. Corder, R. L. Miller

Agronomy Notes

Fertility and insect control programs have a major influence on tobacco production. The proper amounts and kinds of fertilizers and insecticides properly placed will make production more economical on beds and fields if either or both are needed.

Is a fertilizer-insecticide mix the best way to meet the fertility needs and t he insecticide needs on tobacco? The following questions and answers should help show how the decision was reached that this method is not recommended.
