Precision agriculture has the capability to reduce excess nitrogen (N) from crop production being released into the environment. This research evaluates the profitability and N use efficiency of utilizing real-time optical sensing with variable-rate technologies (VRT) to manage spatial...

Native warm-season grasses (NWSGs) have demonstrated potential to reduce summer forage variability in the region, and there has been growing interest in the use of NWSGs as a lignocellulosic biomass crop. The objectives of this research were to determine if there was a difference in beef yield...

Supplemental irrigation in corn production is increasing for humid regions across the world. Little is known about the profitability of irrigating corn in the humid southeastern region of the United States. Our objective was to determine the breakeven price of corn where investment in...

Deterministic and stochastic yield response plateau functions were estimated to determine the expected profit-maximizing nitrogen rates, yields, and net returns for corn grown after corn, cotton, and soybeans. The stochastic response functions were more appropriate than their deterministic...

Irrigation is expensive in Tennessee because of small, irregular fields. We calculated the breakeven corn prices for irrigated corn in Tennessee. Breakeven prices were $4.02-$7.94/bu depending on field size, energy source, and energy price. At current prices, irrigated corn is profitable, but...

It is generally believed that preprocessing procedure can reduce the transportation and storage costs of biomass feedstock for biofuel production by condensing the feedstock’s size. However, the capital costs of preprocessing facilities could be significant in the feedstock logistics system....
