Trends In Alfalfa Production And The Beef And Dairy Industries In Kentucky During 1989-98, Dennis Hancock, Michael Collins
Trends In Alfalfa Production And The Beef And Dairy Industries In Kentucky During 1989-98, Dennis Hancock, Michael Collins
Agronomy Notes
On suitable soils, alfalfa produces the highest yield of nutrients possible from a perennial forage crop. However, high production costs and restrictive soil requirements have limited the production of alfalfa in Kentucky. High producing dairy cows respond well to premium quality forage, so alfalfa is a preferred forage crop in dairy production. Thus, alfalfa production is primarily contingent on the producer’s method of marketing the crop.
The Effect Of Drying Soil Samples On Soil Test Potassium Values, Kenneth L. Wells, James E. Dollarhide
The Effect Of Drying Soil Samples On Soil Test Potassium Values, Kenneth L. Wells, James E. Dollarhide
Agronomy Notes
Extreme temporal and spatial variability of soil test potassium values (STK) was measured on small plots (12-ft x 40-ft) being used for a STK correlation and calibration study on a Crider soil in Larue County, Kentucky. Twelve periodic samplings of the 20 small plots in this study over a period of 18 months showed as much as two-fold temporal differences in STK within individual plots, many of which had received no potassium (K) fertilizer during the study. Spatial variability of STK also varied as much as two-fold among the individual small plots at any given sampling time for similar treatments. …
Comparison Of Weed Management Strategies With Roundup Ready® Corn, J. A. Ferrell, William W. Witt
Comparison Of Weed Management Strategies With Roundup Ready® Corn, J. A. Ferrell, William W. Witt
Agronomy Notes
Corn weed management during the past several years in Kentucky has centered around two herbicide families, the chloroacetamides (Dual, Frontier, Harness, Micro-Tech, Surpass) and the s-triazines (AAtrex, Bladex, Princep). These products have been used widely because they offer acceptable, full season control of many common warm season annual weeds at a reasonable price. This combination has been so popular that several premixtures that contain these types of herbicides (Bicep II, Bullet, Guardsman, Harness Xtra, Surpass 100, FulTime) are used commonly used in Kentucky. The key to this efficacious and economic program is atrazine because it controls most annual broadleaf …
Small Scale Temporal And Spatial Variability Of Potassium Soil Test Values On A Crider Soil, Kenneth L. Wells, James E. Dollarhide, Frank J. Sikora
Small Scale Temporal And Spatial Variability Of Potassium Soil Test Values On A Crider Soil, Kenneth L. Wells, James E. Dollarhide, Frank J. Sikora
Agronomy Notes
An on-farm, small plot study conducted in 1996, on a Crider soil in Larue County, Kentucky, resulted in unanticipated wide variability of soil test potassium (STK) values between spring and fall sampling. Because of this, the small plots were sampled monthly over a period of time with the objective of determining if such variability in STK values was real.
