Kentucky Alfalfa Variety Testing Program, Roy E. Sigafus

Kentucky Alfalfa and Stored Forage Conference

In the 1950's and 60's alfalfa variety trials were conducted by the Lexington staff at 5 to 7 locations. Trials are now limited to Lexington and Princeton, but numerous demonstration seedings are established by the Extension Service personnel throughout the state.

Establishment And Early Management Of Alfalfa Stands For Hay And Silage Production, J. Kenneth Evans, Charles T. Dougherty

Kentucky Alfalfa and Stored Forage Conference

To achieve high levels of productivity and long-lived alfalfa stands, farmers must treat alfalfa as a crop and not as a pasture on the back forty. In this paper we present current recommendations for establishment and early management of alfalfa stands in Kentucky. See AGR-76, Alfalfa-The Queen of Forage Crops, and AGR-64, Establishing Forage Crops, for more detailed information.

Alfalfa In Kentucky — Situation And Challenge, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

Alfalfa is one of the most important forage crops in the United States. Of all commonly grown forages, it is among the highest in feeding value and has the highest yield potential of all adapted perennial forage legumes. Alfalfa is grown over a wide range of soil and climatic conditions and can play an important role in soil conservation. Alfalfa is a versatile crop which can be used as pasture, hay and silgage. As a result of its versatility, yield potential and quality, it can be used successfully in all livestock feeding programs.

Effect Of Fertilizer Salts On Crop Production, V. P. Evangelou

Soil Science News and Views

Soil consists largely of mineral and organic matter, air, and water. Plants obtain nutrients from mineral and organic matter, oxygen from air, and they use water as a carrier of nutrients from the soil into the root and to the above ground portion of plants.

Since soil water functions as a carrier of nutrients from solid fractions of soil into and through plants, it plays a very important role in plant nutrition. Because of this importance, correct chemical balance of the soil solution is necessary for best crop performance. This means that pH of the solution should be in the …

Preface

The computer brightened the 1970s considerably by giving researchers a tool for storing, retrieving and manipulating electronically sizable blocks of literary material on a single subject. which would otherwise have cost researchers years of scholarly investigation to bring together. It was in such a propitious moment mat we set out to assemble this state bibliography as an aid to scholars, researchers. scientists, teachers, writers, editors, and decision makers in the earth sciences, universities, and all levels of government.

As we collected, compiled, and checked citations for this bibliography, we relied heavily on the following standard sources that have indexed …

Seedbed Preparation For Pasture Renovation, Harold B. Rice

Soil Science News and Views

In Kentucky renovation has come to mean the re-establishment of legumes in grass pastures and meadows. Many acres of grassland do not contain enough legumes to fill the amount of nitrogen needed and to improve the nutritional value of the forage. A good stand of white clover, for example, has the capacity to fix about 100 pounds of nitrogen per acre. Because of this, pastures containing around 40 percent clover can produce about as much meat or milk as grass pastures fertilized with 150 pounds of nitrogen per acre. For best results in seeding clovers into grass sods, fields should …

Hydrological Studies In Soil Salinity, C J. Henschke

Resource management technical reports

Investigations involved examination of near-surface indurated layers to investigate their role in saltland formation. It was found that groundwater could move readily through this layer due to the presence of macro-pores. Close examination of apparently impermeable pallid zone clays, shows that decayed tree roots and large diameter voids provide a continuous pathway for the veritical transport of saline water from deeper aquifers.

The Effects Of Ultraviolet-B Radiation On Plant Competition In Terrestrial Ecosystems, Warren G. Gold, Martyn M. Caldwell

Green Canyon Environmental Research Area, Logan Utah

Evidence regarding the interaction of ultraviolet-B radiation and plant competition in terrestrial ecosystems is examined. The competitive interactions of some species pairs were affected even by ambient solar UV-B radiation when compared to control pairs grown without UV-B. Also, the total shoot biomass of these species pairs was depressed under ambient UV-B. Relatively large increases in UV-B radiation altered the competitive interactions of some species pairs grown in pots under field conditions, but did not affect the total shoot biomass production of those pairs. Recent field experiments have examined the competitive interactions of wheat and wild oat under a simulated …
