Corn is a summer annual crop that is grown widely across Kentucky, the United States, and around the world. In the United States, field corn is grown on about 85 million acres (34 million hectares) while sweet corn is grown on about 600,000 acres (240,000 hectares) and popcorn is grown on about 200,000 acres (81,000 hectares). Most of the field corn across the United States is yellow dent corn. In Kentucky, both yellow dent corn and white dent corn are grown. Corn acres in Kentucky peaked at 3.85 million in 1917 and have been around 1.2 to 1.5 million acres since the 1970s (USDA-NASS, 2020). Most corn in Kentucky today is grown in minimum tillage or no-tillage conditions. Most corn acres are rotated with soybean or wheat and double-crop soybeans.

AEN-170: When to Replace Sprayer Nozzle Tips

Tim Stombaugh | Dec. 5, 2022 (New)

Nozzle tips are critical sprayer components for achieving accurate and uniform application of chemicals. Furthermore, nozzle tips are not cheap, especially when considering how many are required on a sprayer. As with any component on a machine, they will not last forever. So when should nozzle tips be replaced? It would be nice if there were a maximum number of sprayed acres or a fixed period of time after which the nozzle tips should be changed for new ones. Unfortunately, there are too many complicating factors to give such a simple answer. This document explains the causes of nozzle tip wear and some simple ways to tell when they should be replaced.

AEN-172: Decision Aid to Determine the Cost of Using a Drone Sprayer in Production Agriculture

Gabriel Abdulai, Joshua Jackson, Karla Ladino, Tim Stombaugh | Nov. 29, 2022 (New)

Similar to other agricultural equipment purchases, cost and potential for return on investment for drone sprayers must be carefully evaluated. General Considerations and Requirements for Drone Spraying (AEN-171) summarized what aspects should be evaluated prior to the purchase of a drone sprayer, or unmanned aerial systems (UAS) sprayer. These aspects include cost considerations, potential uses, certificates and licenses, equipment, utilities, software, insurance, maintenance and repairs, and time allocation.

PA-9: Technology to Improve Sprayer Accuracy

Tim Stombaugh | Mar. 26, 2014 (New)

A number of new technologies have been introduced over the last several years aimed at improving the accuracy of spray application, but do they really work? The purpose of this document is to highlight the most common causes of application errors then discuss the array of new sprayer technologies that are becoming available, how they might affect application accuracy, and pitfalls involved in using them.

ID-214: Mulching with Large Round Bales between Plastic-covered Beds

Tim Coolong, Tim Stombaugh, John Wilhoit | Apr. 26, 2013 (New)

Large round bales lend themselves very well to the application of mulching rows of vegetables because the bales can be unrolled to peel off layers that are about the right thickness for mulch. An innovative implement that offsets the bale so that it can be unrolled between the rows while the tractor straddles the row can make the practice of mulching with round bales considerably more efficient.

AEN-112: A New Concept in On-Farm Biofuel Production

Will Adams, Michael Montross, Sue Nokes, Tim Stombaugh | Mar. 19, 2012 (New)

For many social, political, and economic reasons, biofuels are moving quickly from the fuel of tomorrow to the fuel of today. Researchers at the University of Kentucky are working on a new system of biofuel production that involves on-farm processing of biomass. This factsheet provides a general overview of this new concept that could have a great impact on agriculture and the fuel-production industry.
