Mineral Nutrition In Broilers: Where Are We At?, Rick Kleyn, Mariana Ciacciariello
Mineral Nutrition In Broilers: Where Are We At?, Rick Kleyn, Mariana Ciacciariello
Proceedings of the Arkansas Nutrition Conference
Mineral nutrition remains an essential consideration for broiler nutritionists. The complex interactions between different minerals sources, other ingredients, and the broiler itself, coupled with their relatively low costs, have led to the current status of elevated levels of minerals in broiler diets. New perspectives on sustainability have brought about a rethink of the way we formulate practical diets. There are considerable opportunities for reducing macro minerals such as calcium and phosphorus, particularly for older birds. Our understanding of attaining an ideal dietary cation-anion balance is confused by the lack of clarity in measuring the balance and the bird’s ability to …
Phosphorus Sorption By Gyttja And Its Effect On The Ph Value And Phosphorus In Acidic Soils, Kadir Saltali, Ahmet Nedi̇rli̇
Phosphorus Sorption By Gyttja And Its Effect On The Ph Value And Phosphorus In Acidic Soils, Kadir Saltali, Ahmet Nedi̇rli̇
Turkish Journal of Agriculture and Forestry
Tea and hazelnut cultivated soils are mainly distributed in Black Sea region of Turkey. Low pH value is a primary problem for those soils; therefore, farmers apply lime once every 3-4 years to raise the pH value of soil. Gyttja is highly rich in organic matter (40.59%) and lime (45.67%), and it is a low cost and considerably abundant in Afşin-Elbistan Coal Basin (estimated reserve is around 4.8 billion tons). The aim of this study was to determine the phosphorus (P) sorption characteristics of gyttja, and its efficiency on P availability and soil's pH value. Optimum P sorption conditions (pH, …
Effect Of Calcium Carbonate Level With Or Without Benzoic Acid On Weanling Pig Growth Performance, Fecal Dry Matter, And Blood Calcium And Phosphorus Concentrations, Alan J. Warner, Joel M. Derouchey, Mike D. Tokach, Jason C. Woodworth, Robert D. Goodband, Jordan T. Gebhardt
Effect Of Calcium Carbonate Level With Or Without Benzoic Acid On Weanling Pig Growth Performance, Fecal Dry Matter, And Blood Calcium And Phosphorus Concentrations, Alan J. Warner, Joel M. Derouchey, Mike D. Tokach, Jason C. Woodworth, Robert D. Goodband, Jordan T. Gebhardt
Kansas Agricultural Experiment Station Research Reports
A total of 360 barrows (DNA Line 200 × 400; initially 13.6 ± 0.07 lb) were used in a 38-d study to evaluate the interactive effects of added dietary calcium carbonate and benzoic acid on nursery pig growth performance, fecal dry matter, and blood Ca and P concentration. Upon arrival to the nursery research facility, pigs were randomly assigned to pens (5 pigs per pen) and pens were allotted to 1 of 6 dietary treatments with 12 pens per treatment. Dietary treatments were formulated to provide 0.45, 0.90, or 1.35% calcium carbonate, with or without 0.5% benzoic acid (VevoVitall, DSM …
Nitrogen Fertilizer Timing And Phosphorus And Potassium Fertilization Rates For Established Endophyte-Free Tall Fescue: Year 3, D. W. Sweeney, J. K. Farney, J. L. Moyer, D. A. Ruiz Diaz
Nitrogen Fertilizer Timing And Phosphorus And Potassium Fertilization Rates For Established Endophyte-Free Tall Fescue: Year 3, D. W. Sweeney, J. K. Farney, J. L. Moyer, D. A. Ruiz Diaz
Kansas Agricultural Experiment Station Research Reports
Tall fescue production was measured during the third production year of a study with locations started in fall of 2016 and fall of 2017. Phosphorus (P) fertilization rate affected spring harvest yield at Site 1, but not at Site 2. Applying nitrogen (N) in late fall or late winter resulted in greater spring yields than applying N in spring or not applying N. However, fall harvest yields at Site 1 were greater with spring N application, but not at Site 2. The third-year tall fescue total yield rank as affected by N fertilizer timing was late winter>late fall=spring>no …

Kansas Agricultural Experiment Station Research Reports
A total of 360 pigs (200 × 400, DNA; initially 21.9 ± 0.42 lb) were used in a 21-d growth trial to determine the available P (aP) release curve for GraINzyme Phytase (Agrivida Inc., Woburn, MA). Pigs were weaned at approximately 21 d of age, randomly allotted to pens based on initial BW and fed common starter diets. From d 18 to 21 post-weaning, all pigs were fed a diet containing 0.11% aP. On d 21 post-weaning, considered d 0 of the study, pens were blocked by BW and randomly allotted to 1 of 8 dietary treatments with 5 pigs …
Evaluation Of Long-Term Phosphorus Fertilizer Placement Effect On Soil Phosphorus And Crop Yield, M. J. Coelho, D. A. Ruiz Diaz
Evaluation Of Long-Term Phosphorus Fertilizer Placement Effect On Soil Phosphorus And Crop Yield, M. J. Coelho, D. A. Ruiz Diaz
Kansas Agricultural Experiment Station Research Reports
Phosphorus (P) accumulation in soil with long-term P fertilizer placements can result in a potentially large available reserve of this nutrient for subsequent crop production. This study investigated the effect of phosphorus fertilizer management (placement: broadcast versus deep band) after ten years on soil P, and yield response of crop rotation. Field studies were conducted for a period of ten years in Manhattan, KS. Three treatments were evaluated: 1) control with no P fertilizer application and two fertilizer treatments (80 lb P2O5/a); 2) surface broadcast; and 3) deep band at approximately 4- to 6-in. depth. All …
