Sulfur And Magnesium Trials With Wheat In West Kentucky, Monroe Rasnake
Sulfur And Magnesium Trials With Wheat In West Kentucky, Monroe Rasnake
Soil Science News and Views
Interest in fertilizing wheat with sulfur and magnesium has increased recently in West Kentucky. This has been due primarily to positive test results in adjoining states and recommendations being made by some commercial people. Previous-testing in Kentucky has shown no response by wheat to sulfur, or to magnesium. However, in order to have current data on which to base recommendations, research plots were established in the fall of 1987 in Todd and Hopkins counties. They were repeated on different farms in 1988, making a total of 4 different sites studied.
Has The Nitrate-Nitrogen In Streams Draining Agricultural Watersheds In Kentucky Changed In The Last 18 Years?, Grant W. Thomas, Gerald R. Haszler, James D. Crutchfield
Has The Nitrate-Nitrogen In Streams Draining Agricultural Watersheds In Kentucky Changed In The Last 18 Years?, Grant W. Thomas, Gerald R. Haszler, James D. Crutchfield
Soil Science News and Views
In 1971 and 1972, we sampled streams across Kentucky for nitrate-nitrogen (NO3-N) during the high-water flow months of January through June. The results were variable and showed a dominant effect of geology and lesser effects of both time and land use on the results. Since that time, use of fertilizer nitrogen (N) has nearly doubled in Kentucky and, further, there is a high degree of concern among the public that NO3-N from fertilizer use may be contaminating streams. The US Environmental Protection Agency has set a maximum of 10 ppm NO3-N in water as …
The Effect Of Fall And Spring Tillage Of A Compacted Soil On Corn And Tobacco Yields, Kenneth L. Wells, Roy V. Catlett
The Effect Of Fall And Spring Tillage Of A Compacted Soil On Corn And Tobacco Yields, Kenneth L. Wells, Roy V. Catlett
Soil Science News and Views
Soil compaction is being diagnosed in increasing instances as the cause of poor crop performance in Kentucky. While the basic causes of compaction can usually be identified, it is much more difficult to prescribe techniques to solve the problem. Following identification of compacted soil as being the cause of poor corn growth in a field in Shelby County, Kentucky, a study was conducted to compare three tillage tools on production of corn and tobacco. The compacted zone was within the top 6-inch layer of soil.

Movement Of Triazine Herbicides In Conventional, Reduced Tillage, And No-Tillage Corn Production, William W. Witt, K. W. Sander
Soil Science News and Views
Herbicides are applied to over 90 percent of the corn acreage in Kentucky and triazine herbicides are used the most. Conservation tillage methods are often used to prevent soil erosion and to conserve soil water. However, as tillage is decreased the dependence on herbicides for weed control often increases. Minimizing herbicide movement from the application sites to non-target areas, such as ground and surface waters, is necessary to maintain optimum water quality.

What Are Land Conservation Districts?, Western Australian Department Of Agriculture
Natural resources published reports
Land conservation groups need your support. Land degradation is not just a farming problem. We change the land and waters in many ways, whether it be clearing of precious natural bush or through the fertilizers which leach from our gardens.
By learning about the Land Conservation Districts achievements and understanding the challenges they face we can better see our own place in the scheme of things.
We will learn the ways to organize for Landcare in other rural areas, or in the city, that will be successful.
This is what the Decade of Landcare is all about - providing an …

Seepage Interceptor Drains For Reducing Waterlogging And Salinity, Don Mcfarlane, Jim Cox
Journal of the Department of Agriculture, Western Australia, Series 4
Shallow interceptor drains can reduce waterlogging on sloping sites. Such drains will more than pay for themselves from the increased crop yield. Recent work has shown that these drains also decrease salinity so that they are cost-effective in the long as well as the short term.

Level Banks Used To Decrease Waterlogging Can Increase Salinity, Don Mcfarlane, Richard Engel, Arjen Ryder, Maurice Eales
Journal of the Department of Agriculture, Western Australia, Series 4
Some farmers have used level W1SALTS banks to control surface zvaters above areas affected by ivaterlogging and salinity. Because the amount of waterlogging has been reduced, crop yields have increased downslope of some banks. However, the banks divert fresh surface water into deeper salty groundwater and, in the long term, worsen salinity. This article details an investigation of the effect of level WIS ALTS banks on saline groundwaters and discusses alternative methods of preventing the waterlogging of saline areas.
Soil And Lithostratigraphy Below The Loveland/Sicily Island Silt, Crowley's Ridge, Arkansas, Donna Porter, Sam Bishop
Soil And Lithostratigraphy Below The Loveland/Sicily Island Silt, Crowley's Ridge, Arkansas, Donna Porter, Sam Bishop
Journal of the Arkansas Academy of Science
Two stratigraphic units between the Loveland/Sicily Island Silt and the Pliocene sand and gravel on Crowley's Ridge were analyzed to determine their origin and assess the degree of pedogenic development. The Crowley's Ridge Loess, the upper unit, was up to 2.6 m thick, was not laterally continuous, and contained a well developed paleosol. The lower unit was a several meter thick sandy facies of the Pliocene sand and gravel which contained a weak paleosol. Particle size analysis revealed that the upper unit exhibited texture similar to the overlying loess units, with unimodal silt comprising greater than 95% of the clay-free …
