A.M. Afifi
1990, Open-File Report 90-315
Approximately 200 km2 around the Mahd adh Dhahab mine were mapped at 1:18,000 scale, with emphasis on establishing the volcanic stratigraphy. The Mahd Group, which rests over a basement of metamorphosed tonalite, is divided into the Lahuf formation and Tuwal formation, which are separated by an unconformity. The Lahuf is...
County-level estimates of nitrogen and phosphorus fertilizer use in the United States, 1945 to 1985
Richard B. Alexander, Richard A. Smith
1990, Open-File Report 90-130
Estimates of nitrogen and phosphorus fertilizer use were made for counties in the United States for the period 1945 to 1985. County fertilizer use estimates were obtained through the disaggregation of state-level fertilizer use in proportion to the amount of state fertilized acreage reported to exist in counties. Numerical values...
