Available in PDF, EPUB and Kindle. Book excerpt: This book addresses basic and applied aspects of two nexus points of microorganisms in agro-ecosystems, namely their functional role as bio-fertilizers and bio-pesticides. Readers will find detailed information on all of the aspects that are required to make a microbe “agriculturally beneficial.” A healthy, balanced soil ecosystem provides a habitat for crops to grow without the need for interventions such as agro-chemicals. No organism in an agro-ecosystem can flourish individually, which is why research on the interaction of microorganisms with higher forms of life has increasingly gained momentum in the last 10-15 years. In fact, most of plants’ life processes only become possible through interactions with microorganisms. Using these “little helpers” as a biological alternative to agro-chemicals is a highly contemporary field of research. The information presented here is based on the authors’ extensive experience in the subject area, gathered in the course of their careers in the field of agricultural microbiology. The book offers a valuable resource for all readers who are actively involved in research on agriculturally beneficial microorganisms. In addition, it will help prepare readers for the future challenges that climate change will pose for agriculture and will help to bridge the current gaps between different scientific communities.

This book was released on 2012 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fertilizer consumption has increased three fold during the past 30 years. It reached one million nutrient tones in 1980/81, two million tons in 1992/93 and three million tons in 2002/03. Urea, today, is made in approximately 75 factories worldwide with a total capacity approaching 100,000,000 tons annually. Urea hydrolyzed by urease. Sodium Thiosulfate (ST) has been reported to inhibit nitrification and urea hydrolysis and thereby reduces volatilization of urea nitrogen as ammonia from soils fertilized with urea. A laboratory experiment was carried out by adding ST to urea (10 % by volume). We evaluated ST as a soil urease inhibitor by studying its effects on urea hydrolysis. Encouraging results were found in reducing NH3 losses when ST was applied it reduced NH3 losses in cotton 35.13%, 31.65% and 35.35%, 32.77% in Rice soils in first and second experiment respectively. It functions as urease and nitrification inhibitor.

Download or read book Ammonia Volatilization from Nitrogen Fertilizers and Wastewater Reuse in the Columbia Basin written by Sarah K. Del Moro and published by . This book was released on 2015 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ammonia (NH3) volatilization and loss from nitrogen (N) fertilizer in agriculture negatively impacts crops, farm profitability, human health and surrounding ecosystems where it is deposited. A significant source of NH3 volatilization occurs from surface application of urea on sandy soils with low pH buffering capacity such as those in the semi-arid Columbia Basin region of Oregon and Washington. Ammonia volatilization can be mitigated by using alternative N fertilizers to urea. Effluent from food processing and energy production industries is also used on cropland as an efficient method to conserve water and nutrients. However, NH3 emissions from effluent application have not been quantified. The objectives of this study were to: (i) quantify NH3-N loss from urea vs. alternative N fertilizer products in a micrometeorological field study and laboratory incubation experiment, and (ii) quantify NH3 emissions from effluent applied to crops using an inverse-dispersion micrometeorological method. The fertilizers evaluated in field and laboratory trials included urea, polymer-coated urea, sulfur-coated urea, urea treated with urease inhibitor [N-(n-butyl) thiophosphoric triamide (NBPT)] and ammonium sulfate (AS). Mixed and fused N salts were also evaluated, including a blend of urea and AS and a blend of AS:ammonium nitrate (AN). A modified passive flux method was used to estimate NH3-N loss from fertilizers in the field experiment for 33 d after application. In the lab incubation trial, NH3 was collected in acid for 43 d after application. In the field trial, cumulative NH3-N loss from urea was 47% of N applied. The alternative N fertilizers reduced NH3-N loss in both the field and laboratory, with the exception of the fused urea:AS blend. The reduction of NH3-N loss ranged from 19 to 68% vs. urea in the field, and 16 to 98% vs. urea in the laboratory. In the second study, a backward Lagrangian stochastic (bLS) model was used to calculate NH3 emissions from alfalfa fields receiving effluent water (average 111 mg L−1 total Kjeldahl N content) generated from a potato processor, a dehydrated onion processor, and a cogeneration plant. An ultraviolet-differential optical absorption spectrometer (UV-DOAS) and three-dimensional sonic anemometer were used to monitor NH3 concentrations, wind speed, and temperature for 43 days downwind of the field. The average NH3-N emission rate was 1.4 kg ha−1 d−1 when effluent was applied vs. 0.5 kg ha−1 d−1 during irrigation without effluent. The greatest average NH3-N emission rate of 6.1 kg ha−1 d−1 resulted from alfalfa harvest. These studies provided insight of relative NH3 loss among a variety of alternative N fertilizers to urea. Additional N mass balance research will be required to validate the accuracy of these NH3 loss quantifications. Compared to urea, all of the alternative fertilizers significantly reduced NH3-N loss, with greatest benefit resulting from NO3p− and NH4p+ fertilizer forms (> 60% reduction vs. urea). The average NH3-N emission rate of 1.4 kg ha−1 d−1 observed during effluent application was nearly three times the rate observed from irrigation without effluent. This study confirmed the potential of alternative N fertilizers to reduce NH3 emission in agriculture in conditions favoring NH3 volatilization. This study also confirmed the need to consider NH3 loss when reusing effluent as a nutrient source for crops.
