A conceptual framework for judging the precision agriculture hypothesis with regard to site-specific nitrogen application
In this study we derive a test that aims to show that the economic optimum nitrogen applications in site-specific management zones are different. In addition, a confidence interval is derived for theExpand

Tillage and Fertilizer Effects on Yield, Profitability, and Risk in a Corn-Wheat-Potato-Wheat Rotation
Reduced tillage results in lower production costs and thus may have economic advantages for farmers. However, yield penalties, specific yield risks, or higher nutrient requirements may counteract theExpand

The impact of uncertainties on predicted GHG emissions of dairy cow production systems
Abstract Dairy farms produce significant greenhouse gas (GHG) emissions and are therefore a focal point for GHG-mitigation practices. To develop viable mitigation options, we need robust (insensitiveExpand

Evaluation of activity meters for estrus detection: A stochastic bioeconomic modeling approach.
Although estrus detection makes a relevant contribution to the reproductive performance of dairy cattle, studies on the economic evaluation of automatic estrus detection systems are rare. TheExpand

Risk and Nitrogen Application Levels
"Stochastic weather and soil conditions are the suggested reasons why farmers tend to apply more than the recommended levels of nitrogen. This study found that uncertainty plays a role in theExpand

Optimal site-specific fertilization and harvesting strategies with respect to crop yield and quality response to nitrogen
Incorrect fertilizer decisions can be costly if quality of the output, in addition to yield, is influenced by the application rate, which contrasts the flat payoff function estimated for fertilizerExpand

Factors Influencing Smallholder Farmers’ Climate Change Perceptions: A Study from Farmers in Ethiopia
Factors influencing climate change perceptions have vital roles in designing strategies to enrich climate change understanding. Despite this, factors that influence smallholder farmers’ climateExpand

Analyzing the effects of risk and uncertainty on optimal tillage and nitrogen fertilizer intensity for field crops in Germany
This study provides a risk analysis of long-term field experiments in Germany (Bavaria) on various field crops (potato, wheat and corn), grown in rotation, under a variety of different tillage andExpand

Economic Potential of Site-Specific Fertiliser Application and Harvest Management
Site-specific fertiliser management has been discussed as an information-based farming concept that uses plant- and soil-specific information. However, agricultural practice has shown that, becauseExpand

How flat is flat? Measuring payoff functions and the implications for site-specific crop management
TLDR
We show that two existing metrics — the relative range of an input for which the payoff is at least 95% as large as the maximum payoff (IR95) and the relative curvature (RC) of the payoff function — are flawed. Expand
