The interest in potash is growing in Arizona as three companies carry out exploration programs east of Holbrook in what could be one of the largest recoverable deposits in the country. This week the Arizona Oil & Gas Conservation Commission issued four more permits for exploration core holes, to Dallas-based HNZ Potash.
A decade ago when potash supply met world demand and prices were low, the United Nations Environmental Program teamed up with the fertilizer industry (IFA) to publish five volumes that looked at a wide range of environmental factors related to potash and phosphate exploration, production, distribution, and use. All five are available online for downloading:
