Subsurface drainage volume reduction with drainage water management: Case studies in Ohio, USA
Gunn, Kpoti M.; Fausey, Norman R.; Shang, Yuhui; … - In: Agricultural Water Management 149 (2015) C, pp. 131-142
Drainage water management (DWM) is promoted as an agricultural best management practice that reduces subsurface drainage volume and thereby the transport of soluble nutrients to streams. This study was conducted on private crop fields to quantify the effect of managed subsurface drainage on...

How Potential Carbon Policies Could Affect Where and How Cotton Is Produced in the United States
Nalley, Lawton Lanier; Popp, Michael P.; Niederman, Zara; … - In: Agricultural and Resource Economics Review 41 (2012) 2
Using life cycle assessment methodology, this analysis evaluates how two carbon reduction strategies affect cotton plantings regionally and methods used to produce cotton. Because cotton production emits large amounts of carbon, the design of a reduction policy as either excluding soil...
