Phosphogypsum As A Source Of Nutrients For Bahiagrass, J E. Rechcigl, I S. Alcordo
Phosphogypsum As A Source Of Nutrients For Bahiagrass, J E. Rechcigl, I S. Alcordo
IGC Proceedings (1977-2023)
Phosphogypsum is a by-product of the manufacture of phosphoric acid from phosphate rock and is a potential source of sulfur and calcium for crops. There are currently more than 700 million Mg of phosphogypsum in Florida alone stacked in waste piles and an additional 30 million Mg produced annually. A 3-year study was conducted to determine whether addition of phosphogypsum to bahiagrass would increase production and quality. Results indicate that addition of up to 4.0 Mg/ha phosphogypsum increased bahiagrass yields, protein content, and in vitro digestibility of forage. This study has demonstrated that phosphogypsum can be used as an alternative …

Application Of N And P Fertilizers On Pasture Of Southern Italy: Effects On Forage Species, Production And Quality, D Ferri, G Convertini
IGC Proceedings (1977-2023)
The effects of N and P fertilization on the productive and qualitative characteristics of improved pastures in inside Southern Italy areas were investigated. The trial was carried out in two sites characterized by different altitude above sea level and soil properties; also previous fertilization treatments and botanical composition characteristics are significantly different. The N fertilization reduced negative effects of climatic variations (typical of these areas) on botanical composition of “Bella” grassland at lower altitude. On the contrary a more stable botanical composition assured good yields and quality of forage at “Li Foy” field (higher a.s.l.) because more regular weather conditions …

Long-Term Effects Of Co2 Enrichment And Temperate Increase On Forage Quality In A Temperate Grass, J F. Soussana, J M. Besle, I Chabaux, P Loiseau, P C. De Faccio Carvalho
IGC Proceedings (1977-2023)
Perennial ryegrass swards were grown during two years at two N fertilizer supplies in elevated (700 ppm) or ambient atmospheric CO2 concentration at outdoor temperature and at + 3°C in elevated CO2. Elevated CO2 and temperature increase had only minor impacts on the digestibility and on the fiber composition of the cut material. On average, the water soluble carbohydrate concentration of the leaf laminae was doubled in elevated CO2, whereas a 3°C temperature increase reduced this concentration by 25 %.

Co2 Enrichment And Temperature Effects On Productivity Of Field-Grown Phalaris And Subterranean Clover, J M. Lilley, T P. Bolger, R M. Gifford
IGC Proceedings (1977-2023)
Pure and mixed swards of Phalaris aquatica and Trifolium subterraneum were exposed to cool (ambient) and warm (cool +3oC) temperatures, at both 380 and 690 ppm CO2 concentrations in field temperature gradient tunnels for 5 months. In general, clover and the mixture had similar forage productivity in each treatment, while phalaris was less productive. Elevated CO2 increased clover production 40% in the monoculture and the mixture. Higher temperatures reduced clover regrowth at ambient CO2 and reduced the response to elevated CO2 in the monoculture but not in the mixture. In contrast, phalaris regrowth in the monoculture was not increased by …

Nutritive Value Of Guineagrass Cultivars In The Winter As Influenced By Nitrogen Fertilization, N.F G. Rethman, W.A J. Steenekamp
Nutritive Value Of Guineagrass Cultivars In The Winter As Influenced By Nitrogen Fertilization, N.F G. Rethman, W.A J. Steenekamp
IGC Proceedings (1977-2023)
The monitoring of yield, structure and nutritive value of four Panicum maximum (Guineagrass) cultivars, utilized as standing hay in the winter, yielded valuable data on the relative importance of nitrogen fertilization and cultivar. While nitrogen had a strong influence on yield and crude protein content it was the differences between cultivars, with respect to soil adaptation and structure, which played a dominant role. It is recommended that future research place particular emphasis on the adaptation of cultivars and genotype differences in structure.

IGC Proceedings (1977-2023)
The objective of these studies was to determine the reasons for chlorosis of desmanthus observed at some sites in southeast Queensland. Inoculation with Rhizobium increased growth of desmanthus in 2 of 4 soils in the field and 4 of 8 soils in pots. Greatest responses occurred in soils with few or no effective native Rhizobium. Most soils however, contained native strains that were effective. Omission of sulphur significantly reduced dry weight of desmanthus grown in pots in 5 of 7 soils by 30-51% relative to plants supplied with all nutrients. Omission of P and Mo resulted in similar yield reductions …

Phosphorus Requirements In Legumes: Calibration Of A Rapid And Simple Tissue Test, A Moron
IGC Proceedings (1977-2023)
The objective of this research was to adjust and calibrate a phosphorus (P) tissue test to diagnose in a simple and rapid manner the nutritional status of commonly used legumes in Uruguay. Field experiments conducted during 1993-94 with four legumes, showed a significant yield response to increasing P fertilizer rates. A colorimetric sap analysis was used to determine P status in legumes. A strong relationship was found between P sap analysis and relative yields. A critical level of 90-100 μg P/ml in sap to attain 90% of the maximum yield was obtained.

Evaluation Of Different Nitrogen Sources On The Production And Chemical Properties Of C4-Sub-Tropic Pastures, J F. Reckling, G.H J. Kruger
IGC Proceedings (1977-2023)
Digitaria eriantha fertilised with limestone ammonium nitrate (LAN 28 % N), although not statistically significant, resulted in higher dry matter production in comparison to those plants fertilised with urea (U 46% N). Significant lower (P<0.05) soil calcium levels were found in plots fertilised with LAN. Plants fertilised with urea had double the amount of Aspartic and Glutamic acid, indicating that urea did not convert to NO3 -, but was taken up as ammonium.

Reducing growth and limiting metabolism are strategies that allow bacteria to survive exposure to environmental stress and antibiotics. During infection, uropathogenic Escherichia coli (UPEC) may enter a quiescent state that enables them to reemerge after the completion of successful antibiotic treatment. Many clinical isolates, including the well-characterized UPEC strain CFT073, also enter a metabolite-dependent, quiescent state in vitro that is reversible with cues, including peptidoglycan-derived peptides and amino acids. Here, we show that quiescent UPEC is antibiotic tolerant and demonstrate that metabolic flux in the tricarboxylic acid (TCA) cycle regulates the UPEC quiescent state via succinyl-CoA. We also demonstrate that …

Exposure to per- and poly-fluoroalkyl substances (PFAS) is ubiquitous due to their persistence in the environment and in humans. Extreme weight loss has been shown to influence concentrations of circulating persistent organic pollutants (POPs). Using data from the multi-center perspective Teen-Longitudinal Assessment of Bariatric Surgery (Teen-LABS) cohort, we investigated changes in plasma-PFAS in adolescents after bariatric surgery. Adolescents (Mean age = 17.1 years, SD = 1.5 years) undergoing bariatric surgery were enrolled in the Teen-LABS study. Plasma-PFAS were measured at the time of surgery and then 6-, 12-, and 36 months post-surgery. Linear mixed effect models were used to evaluate …

The long-term irrational use of chemical pesticides has led to severe ecological, environmental, and human safety concerns, although chemical pesticides play an important role in increasing crop yields. In response, China has issued a series of policies to reduce the use of chemical pesticides, aiming to ensure food and agricultural safety while promoting high-quality agricultural development. Reducing the usage of chemical pesticides must be complemented by the adoption of biological pesticides. Globally, biological pesticides currently account for approximately 40% of total pesticide usage in many countries. Mycoinsecticide, characterized by their environmental friendliness, sustainability, and low resistance development, represents an important …
