Water quality and productivity changes associated with the liming of a soft water lake
Sherwood Lake, a 165 acre public fishing impoundment in Greenbrier County, West Virginia, was treated with calcium carbonate for four years. The limestone treatment was done by revolving limestone drums installed above the lake on Meadow Creek. The limestone drum provided continuous treatment …

Effects of different rates of liming on crop yields and soil reactions on different soil types
To determine the most profitable rates of applying lime for different crops on different soil types in the State, and to determine if possible the hydrogen ion concentration for the most economic yields of the different crops on different soil types. Plots will be laid out at Blacksburg, Staunton, …

Effects of liming on plankton and young-of-the-year bluegill growth in Flat Top Lake, West Virginia
The responses at three trophic levels (phytoplankton, zooplankton, young-of-the-year bluegill) were compared between a limed and unlimed arm in a moderately fertile, circumneutral reservoir that was sensitive to acidification, but had not yet shown signs of damage. The east arm (25.5 ha) of Flat …

Liming Characteristics of a High-Calcium, Dry Flue Gas Desulfurization By-product and its Effects on Runoff Water Quality
… The purpose of this research was to identify the liming characteristics of a high-Ca dry FGD (DFGD) by-product in comparison to a Class-C fly ash (FA) and reagent-grade CaCO3, and to evaluate the effects of land application to a managed grassland on runoff, plant, and soil quality. Liming …

A study of the effects of different rates of liming on soil reaction and growth of certain crop plants
(1) The experiment as a whole showed that pH determinations may be made at any time throughout the year with assurance of being reliable as a relative indicator of lime requirement. (2) A comparison of the pH determinations made in 1928 with those made in 1930-31, show that the plats have become …

The Physiological Impacts of Soil Alkalising Agents on Legumes.
… of these, cement kiln dust (CKD), is a potential liming agent and potassium fertiliser. In a field trial, CKD equally increased soil pH and available potassium when compared to agricultural lime and a commercial potassium fertiliser. However, pod yield of field bean (Vicia Faba L. cv Fuego) was …

PHYSIOLOGY AND PERSISTENCE OF ALFALFA WITH CHANGES IN SOIL CHEMISTRY
<p>The influence of liming on soil chemical changes and on nodulation, nitrogen fixation and yield of alfalfa was investigated.</p><p>In the field, increasing rates of lime improved alfalfa dry matter yield at the Kingman Farm. Optimum dry matter yield was obtained with 3.5 tons lime/ha. A …

GROWTH, NODULATION AND NITROGEN FIXATION OF ALFALFA (MEDICAGO SATIVA L) AND RED CLOVER (TRIFOLIUM PRATENSE L) AS INFLUENCED BY SOIL ACIDITY AND LIMING
… to examine the influence of soil acidity and liming on the growth of Rhizobium and the nodulation, nitrogen fixation, and yield of alfalfa and red clover.</p><p>In the greenhouse, from soil pH 5.0 to 5.6, nitrogen fixation was shown to be more correlated to Al saturation than pH or available …

Understanding the Role of Home Community Environments in Shaping First-Generation Jamaican University Students’ Access and Persistence in Higher Education: Using Liming and Photovoice Methodologies
… access and persistence. Specifically, through liming and photovoice methodologies, a total of ten participants shared how their rural and urban inner-city communities shaped their university journey and experiences. The study’s four findings revealed that first-generation Jamaican university …

Cotton Yield as Related to Selected Physical and Chemical Properties of Soils of the Coastal Plain of Virginia and North Carolina
… the effect of subsoiling and/or subsurface liming on cotton development and root growth. Two hundred sites were sampled across the Coastal Plain of Virginia and North Carolina to a depth of 92 cm representing 5 major soil series. Soil samples were analyzed for selected physical and chemical …

The influence of land management on upland water quality, notably the production of soluble colour in supply
… studied included burning, ditching and liming, and consideration was given to the suggestion that liming may reduce the amount of colour in raw waters. These practices were found to increase soluble colour and in turn, levels of iron and aluminium in supply. Burning and ditching …

Linking Carbon, Nitrogen, And Calcium Cycling In Northeastern U.S. Forests
… N, and Ca cycling, and how increasing soil Ca by liming affects C and N pools, fluxes, and dissolved organic matter retention. In chapter 1, I show how Norway spruce, red oak, and sugar maple planted in a common garden influence soil C, N, and Ca pools. Norway spruce had the largest C and N stocks …

Fundamental aspects of the chrome tanning reaction
… Amide group hydrolysis during conventional liming proceeds by two mechanisms: direct hydrolysis with hydroxyl catalysis or intramolecular catalysed hydrolysis that can be measured by the degree of racemisation at Lasparagine Gas chromatography mass spectrometry analysis of limed collagen …

Improved Management of Acid Sulfate Soils for Rice Production in Casamance, Senegal
… year these effects diminished, suggesting that liming effects did not persist as expected. These results demonstrate the benefits of soil amendments that raise soil pH and suggest that this effect operates by influencing overall soil nutrient availability to rice plants, but further research is …

Sea trout (Salmo trutta L.) : studies of the River Twyi, South Wales
… and juvenile salmonids, through reservoir liming, was studied.

Factors Contributing to Trimethylamine Generation from Limed and Polymer Conditioned Sludges
… TMA was the time between conditioning and liming. If this time was minimized, little TMA was produced, even at high polymer doses. Data also suggests that methanogens play an important role in the breakdown of TMA.

Impact of soil acidity on groundnut productivity in Mpumalanga and KwaZulu - Natal Province
… Kwarts and ICGV 90071 were insensitive to liming as their grain yields did not respond to liming at the Lowveld College of Agriculture farm. Also, Rambo was insensitive to liming at Manguzi. The variety Kwarts was found to be better suited for acidic soil conditions at Lowveld College of …
