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...

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...

Profit-maximizing nitrogen rates were determined for two bermudagrass hay producers, one who considers nitrate toxicity to cattle and one who does not consider nitrate toxicity. Producing bermudagrass hay with a reduced probability of nitrate toxicity requires a $6.02/ton premium to breakeven...

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...

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...

Accumulation of nitrates in hay can be toxic to cattle, and managing nitrate levels in hay production could be costly. We determine the price premium a hay producer needs to receive for cattle-safe, low-nitrate hay to continued managing nitrate levels. Profit-maximizing nitrogen rates were...
