Six irrigation systems are analyzed considering cost and potential water savings. The investment cost of furrow and drip is $115,800 and $260,120, respectively. The cost of quarter mile pivot ranges from $59,000 to $64,000. Per ac-in variable pumping cost ranges $9.96 to $14.86 assuming natural...

With increasing environmental concerns, increasing population, changing tastes and preferences of consumers towards healthier foods, and with more food safety requirements, agronomic practices have changed gradually to provide not only food and fiber but also public goods and other beneficial...

Irrigated acreage is an important indicator for agricultural water demand which is a major category of water use. Three methodologies were applied in this study to project irrigated acreage of major crops in Georgia from 2010 to 2050. These three methodologies show consistent results. Total...

Three manure application limits (N Limit, Annual P Limit and P Banking) were modeled with particular attention to the number of hours needed to appropriately distribute manure. The benefit and costs estimates indicated that P Banking was more profitable than N Limit which was more profitable...

Wheat regression models that account for the effect of weather are developed to forecast wheat yield and quality. Spatial lag effects are included. Wheat yield, protein, and test weight level are strongly influenced by weather variables. The forecasting power of the yield and protein models was...

This paper evaluated differences between yields of no-tillage compared to conventional or reduced tillage and their associated downside risk. Six crops were evaluated along with how those yields and risks differed by various environmental factors such geographic location, precipitation, soil...

Heavy withdrawals from the most dependable source of groundwater in the Texas Panhandle, the Ogallala Aquifer, create an impending need for implementing water conservation policies. This study evaluates the policy option of multi-year water allocation coupled with water use restriction in four...

The cost-profit relations of organic and conventional farming were examined on the basis of natural and financial data of a large agricultural - company in western Hungary and of economic models characterising private farms in eastern Hungary. The differences in cost structures reflect variable...
