The evidence to date shows that these three types of maize production have co-existed without economic and commercial problems. This includes in regions such as Catalunya where GM (Bt) is concentrated. Where non GM maize has been required in some markets, supplies have been relatively easily obtained, based on market-driven adherence to on/post farm segregation and by the purchase of maize from...

A simultaneous equations, or "switching-regression," model is developed to assess the impact of soil nitrogen (N) testing on N fertilizer use, crop yields, and net returns in corn growing areas of Nebraska. The results indicate that when there is uncertainty about the quantity of available "carry-over" N, N testing enables farmers to reduce fertilizer use without affecting crop yields. However,...

Discussion on plant genetic engineering has experienced increasing momentum with the introduction of Genetically Modified (GM) corn in Germany and other European countries. This paper determines the various groups of German farmers, their attitudes and expected decisions on the use of GM foods using cluster analysis of 370 German farm managers. The results of cluster analysis indicate five main...

An agronomic crop growth model—the Decision Support System for Agro-Technology Transfer—and a constant relative risk aversion utility function are used to examine corn irrigation strategies in Mitchell County, Georgia. Precipitation contracts are designed to help farmers manage risk. Three conclusions originate from the findings. First, the optimal irrigation strategy can greatly increase produ...

dairy herd. The quality of these forages greatly impacts profitability and performance, especially of the milking herd. Because of limited land base, labor, or personal preference, farmers may decide to purchase part or all of their herd’s forage needs. In other parts of the United States, corn silage and other chopped forages are sold and oftentimes delivered to the farm as needed. In Kentucky...

It is rather remarkable that a process as esoteric as the genetic modification of crops would become the subject of a global war of rhetoric. Yet for the past few years Western audiences have been bombarded with deceptive rhetoric, spin, and soundbite science portraying the wonders—or horrors—of the new technology. Books and fullpage newspaper advertisements warn of a wrecked environment and fo...

The construction of multi-media information resources of crops and livestock is discussed for interactive three-dimensional animation education in the paper. The animation technology, three-dimensional visualization technology and digital entertainment pattern are combined with modern agricultural science technology knowledge and the production process. Based on the application of virtual reali...

I t is almost autumn in Kansas, and the corn continues to grow in some fields. The fall harvest is still a few weeks off. However, the farmers in my area will tell you that what happens now will determine the harvest’s outcome. Physician practices must think in the same way. The ICD-9 updates have been released, making this a good time to review your superbills for needed revisions. Doing this ...

When I request a memory from 2012 to dairy farmers, almost unanimously they respond “drought stress.” According to the US Department of Agriculture (USDA, 2013), the spring and summer drought of 2012 will be remembered as one of the “worst agricultural calamities” in the United States (USDA, 2013). The drought of 2012 reduced the national corn grain and silage yields by 16.2 and 16.3%, respecti...

Nitrogen applied before planting is more vulnerable to lobs to the environment than nitrogen applied during the gro~ving season, but the growing season application can increase the risk o f lower yields c;iused by adverse weather that prohibits farmers to cornplete N application. An expected utility framework is used to illustrate the potential econo~nic benefit of insurance for :I farmer to re...
