A Comprehensive Guide to Wheat Management in Kentucky
2/23/2016 (reprinted)

 UK Authors: Bill Bruening, J.D. Green, John
 Departments: Agricultural Economics, Biosystems and Agricultural Engineering,
 Series: Interdepartmental (ID series)
 Tags: farm crops, grain crops, small grains

The soft red winter wheat grown in Kentucky is the fourth most valuable cash crop in the state. Winter wheat has been an integral part of crop rotation for Kentucky farmers. Wheat is normally harvested in June in Kentucky and provides an important source of cash flow during the summer months.

Agricultural Lime Recommendations Based on Lime Quality
1/13/2016 (major revision)

 UK Authors: David Ditsch, Josh McGrath,
 Departments: Plant and Soil Sciences, Regulatory Services
 Series: Interdepartmental (ID series)
 Tags: nutrient management, soil and land

Soil acidity is one of the most important soil factors affecting crop growth and ultimately, yield and profitability. It is determined by measuring the soil pH, which is a measure of the amount of hydrogen ions in the soil solution. As soil acidity increases, the soil pH decreases. Soils tend to be naturally acidic in areas where rainfall is sufficient to cause substantial leaching of basic ions (such as calcium and magnesium), which are replaced by hydrogen ions. Most soils in Kentucky are naturally acidic because of our abundant rainfall.

Fertilizer Management in Alfalfa
1/8/2014 (new)

 UK Authors: David Ditsch, Lloyd Murdock,
 Departments: Plant and Soil Sciences
 Series: Agronomy (AGR series)
 Tags: cover and forage crops, farm crops, legumes

Alfalfa is a high quality, valuable forage crop that can be successfully produced on most well-drained soils in Kentucky for hay, silage, and grazing. Fertilizing alfalfa can be uniquely challenging because it is a high-yielding crop that removes a tremendous amount of soil nutrients when compared to other crops grown in Kentucky. A thorough understanding of alfalfa's growth habits, nutrient requirements, and soil nutrient supply mechanisms is necessary to effectively manage fertilizer inputs and maximize profitability while minimizing environmental impact.

 Series: Progress Report (PR series)
 Tags: farm crops, grain crops, research,

The 2012 Soybean Management Verification Program (SoyMVP) enrolled 19 fields across Western Kentucky, providing ten direct comparisons between University of Kentucky recommendations and producers practices for soybean production. All fields were scouted weekly and recommendations were made on the university portion of the field based on established thresholds and observations from agronomic research. The objective of these comparisons is to validate university research and identify areas for more research.

Profitability of Nitrogen Applications for Stockpiling Tall Fescue Pastures: 2011 Guide

 UK Authors: Kenny Burdine, Greg Halich, Jo
 Departments: Agricultural Economics, Animal and Food Sciences,
 Series: Interdepartmental (ID series)
 Tags: cover and forage crops, farm crops, grasses

The concept of stockpiling is pretty straightforward, but the challenge each year is to determine the likelihood that this practice will be profitable given the economic and agronomic conditions present at mid-summer. This practice can yield significant benefits, but it also carries significant costs. These benefits and costs must be quantified and compared to assess the overall profitability of the practice.

Nitrogen Transformation Inhibitors and Controlled-Release Urea

 UK Authors: Lloyd Murdock, Greg Schwab

 Series: Agronomy (AGR series)
 Tags: nutrient management

The soaring cost of fossil fuels is an indicator that nitrogen fertilizer prices are going to remain high for the foreseeable future. With higher N prices, many producers are trying to evaluate the usefulness of several N additive products in their production systems. High N prices make these products more attractive because it takes fewer pounds of saved N to offset the price of the additive. Producers should have a good understanding of how these products work in order to make informed decisions regarding their use.

Corn and Soybean Production Calendar

 UK Authors: Ric Bessin, J.D. Green, Jim Herbek
 Departments: Agricultural Economics, Biosystems and Agricultural Engineering,
 Series: Interdepartmental (ID series)
 Tags: corn, farm crops, grain crops,

The Corn and Soybean Production Calendar was developed to help producers prioritize and schedule work events in a timely fashion on the farm. Weather events and equipment breakdowns rarely follow an organized schedule. However, if other practices within the farming operation are prioritized, perhaps a producer can better address the emergencies that will occur.

Comparing No-Till and Tilled Wheat in Kentucky

 UK Authors: Dottie Call, Larry Grabau, John

 Tags: farm crops, grain crops, small grains

Historically, wheat planting in Kentucky has involved tillage. With conventional tillage practices, most residues from the previous crop are cut and buried prior to seeding wheat. No-till wheat planting eliminates tillage and reduces soil erosion, particularly on sloping soils, as well as reducing labor, machinery, and energy costs.

Compaction, Tillage Method, and Subsoiling Effects on Crop Production
1/11/2008 (new)

 UK Authors: Dottie Call, John James, Lloyd
 Departments: Plant and Soil Sciences
 Series: Agronomy (AGR series)
 Tags: soil and land

No-tillage is the preferred method of crop production for most Kentucky farmers. No-tillage has been proven to increase soil quality and decrease the risk of soil compaction as compared to crop production using annual tillage. However, with the use of heavy farm equipment, soil compaction is always a threat with either tillage or no-tillage. The possibility of soil compaction and its effect on crop production is a constant concern to many farmers using no-tillage. If soil compaction occurs, is there a difference between the two tillage systems on how it affects crop production and the recovery of the soil with and without subsoil tillage? The following study was conducted to help producers and advisors understand soil compaction and its effects on corn and soybean production as well as the ability of the two tillage systems to recover from soil compaction.

 Tags: nutrient management, soil and land

The most important part of making fertilizer recommendations is collecting a good, representative soil sample. Soil test results and fertilizer recommendations are based solely on the few ounces of soil submitted to the laboratory for analysis. These few ounces can represent several million pounds of soil in the field. If this sample does not reflect actual soil conditions, the results can be misleading and lead to costly over- or under-fertilization. It is necessary to make sure that the soil sample sent to the laboratory accurately represents the area sampled.

A Comprehensive Guide to Corn Management in Kentucky
9/30/2001 (new)

 UK Authors: Ric Bessin, Morris Bitzer, J.D.
 Departments: Agricultural Economics, Biosystems and Agricultural Engineering,
 Series: Interdepartmental (ID series)
 Tags: corn, farm crops, grain crops,

The corn grown in Kentucky is used mainly for livestock feed and as a cash crop. As a cash crop sold from the farm, corn ranks third behind tobacco and soybeans but is the number one row crop in terms of acreage. Because the cost of producing an acre of corn is high and the value per bushel has declined in recent years, producers must manage and market their corn crop more carefully for adequate profits. The goal of this publication is to serve as a guide for corn production strategies that focus on efficient use of resources and provide the principles and practices for obtaining maximum, profitable corn yields.
