Download or read book Enhanced Efficiency Nitrogen Fertilizers for Nitrogen Management in the Columbia Basin Oregon written by Jess Charles Holcomb and published by . This book was released on 2011 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ammonia (NH3) volatilization can result in a substantial amount of surface applied nitrogen (N) being lost into the atmosphere, making it an environmental pollutant as well as reducing plant-available N. However, N can also be easily lost from the soil through leaching, and nitrous oxide (NO2). Enhanced efficiency N fertilizers and cultural practices can be used to reduce N pollution and keep N plant-available. The use of these fertilizers and practices has not been examined in the Columbia Basin in Oregon. The objectives of this study were to: (i) examine the effective irrigation rate needed to reduce loss from volatilization from urea, (ii) examine the effectiveness of urease inhibitors in minimizing NH3 loss, measure interactions between inhibitors and irrigation, and measure hydrolysis rates with inhibitors, and (iii) examine if enhanced efficiency N fertilizers could maintain or increase potato yields, whether petiole NO3 accurately reflected plant N with these products, and if they release N according to plant uptake. In the first study, irrigation rates of 0.0 to 22 mm were applied over surface applied urea using a center pivot irrigation system on a wheat field. Ammonia was collected from each plot using the modified passive flux method for 23 days after application (DAA). Cumulative loss of N as NH3 ranged from 3 to 67 kg N acre−1, with the application of 8 mm irrigation reducing loss to 19 kg N ha−1. Peak NH3 loss occurred between 2 and 8 DAA. The reduction of N loss by 90% was obtained through the application of 15 mm irrigation. Increased wheat N concentration was associated with decreased NH3 loss. The second study consisted of recording NH3 loss on a grass seed field from urea, ammonium sulfate, and Agrotain-treated urea. This study also involved recording NH3 loss on a wheat field from urea, Agrotain, and an organo acid complex containing co-polymers (OAC) treated urea at irrigation rates of 0.0, 1.25, and 7.6-mm. Volatilization loss was measured using the modified passive flux method. Urea, Agrotain, and OAC were incubated with soil at three temperatures to measure hydrolysis rates. In the grass seed study Agrotain reduced N loss from NH3 by 71.8% compared to urea, while ammonium sulfate reduced loss by 60.4% compared to urea. In the wheat study, Agrotain lost 5.72 to 6.24% N applied at the 0.00 and 1.25-mm irrigation rate, compared to 53.44% to 60.05% N applied for urea and OAC. With the application of 7.6-mm irrigation, all loss declined with rates of 17.31, 8.11, and 3.17 N applied for urea, OAC, and Agrotain, respectively. Agrotain also decreased urease activity in the wheat field compared to urea and OAC. In incubation, Agrotain delayed complete hydrolysis by 7 days at 26.7°C, 15 days at 16.6°C, and 49 days at 4.4°C compared to urea and OAC. Urea and OAC had similar hydrolysis rates at all temperatures. The use of an effective urease inhibitor, such as Agrotain, can be used to delay hydrolysis and reduce NH3 loss if urea cannot be incorporated. In the final study, enhanced efficiency N fertilizers were applied to Russet Norkota and Russet Burbank potatoes to compare yield and quality with grower standard practices (GSP). Plant N samples were taken from the third year to examine whether petiole nitrate accurately reflected plant N with these products. An incubation of all products for 104 DAA was performed at 4.4°C, 16.6°C, and 26.7°C to measure ammonium (NH4) and nitrate (NO3) formation. Similar yields were measured for both years with Russet Norkota. All N treatments were similar, even the 80% GSP, suggesting that N rates were in excess of crop need, thereby reducing sensitivity of N-inhibitor measurements. Reduced yields were measured in two years for Russet Burbank when enhanced efficiency fertilizers were applied compared to 100% GSP. Enhanced efficiency fertilizers maintained yields for one year compared to 100% GSP. Yields with N treatments were usually similar to the 80% GSP, suggesting that N release was not matched with N uptake. In the incubation study, all products except Nutrisphere-N (NSN) were able to delay N release compared to urea. Each product was influenced by temperature, with decreased temperature resulting in a longer delay in conversion of urea to NH4 and conversion of NH4 to NO3 N. Nitamin and N-fusion had only 100% N available at 26.7°C after 104 day. Enhanced efficiency N fertilizers cannot sustain or increase yields on a yearly basis, making their incorporation into Columbia Basin potato production impracticable based on economics. Enhanced efficiency N fertilizers and cultural practices can reduce N loss. However, a reduction in N loss does not always lead to sustained or increased yields. The use of cultural practices can be implemented with minimal expense; however, the fertilizers must present an economical benefit, either as increased yield or a N reduction to be viable in most cropping systems.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents an exhaustive analysis of the trends in the development and use of natural and synthetic polymer systems aimed at sustainable agricultural production. The polymers have allowed the development of controlled and released systems of agrochemicals such as pesticides, fertilizers and phytohormones through micro and nanoencapsulated systems, which protect and stimulate the growth of crops at low costs and without damage to the environment. Hydrogel systems from natural and synthetic polymers have also had their place in the agricultural industry, since they allow to maintain the humidity conditions of the crops for their correct development in drought times. Mulch films made of polymers have also become important in the control of weeds and pests in crops, as well as the use of edible coatings applied to fruits and vegetables during post-harvest, which reduce the losses of these perishable foods. Currently, the systems indicated, as well as others, are already used on a large scale. However, research studies in this area have been limited compared to other polymer applications. This book collects useful information for researchers, students and technologies related to the polymer technology and agri-food production. In this book, world-renowned researchers have participated, including associate editors of important journals, as well as researchers working in the area of research and development (R&D) of leading agri-food industries in the manufacture of agricultural inputs.

Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen is the most yield-restraining nutrient in crop production globally. Efficient nitrogen management is one of the most important factor for improving nitrogen use efficiency, field crops productivity and profitability. Efficient use of nitrogen for crop production is therefore very important for increasing grain yield, maximizing economic return and minimizing nitrous oxide (N2O) emission from the fields and nitrate (NO3) leaching to ground water. Integrated nitrogen management is a good strategy to improve plant growth, increase yield and yield components, grain quality and reduce environmental problems. Integrated nitrogen management (combined use of chemical + organic + bio-fertilizers) in field crop production is more resilient to climate change.

Available in PDF, EPUB and Kindle. Book excerpt: This book addresses in detail multifaceted approaches to boosting nutrient use efficiency (NUE) that are modified by plant interactions with environmental variables and combine physiological, microbial, biotechnological and agronomic aspects. Conveying an in-depth understanding of the topic will spark the development of new cultivars and strains to induce NUE, coupled with best management practices that will immensely benefit agricultural systems, safeguarding their soil, water, and air quality. Written by recognized experts in the field, the book is intended to provide students, scientists and policymakers with essential insights into holistic approaches to NUE, as well as an overview of some successful case studies. In the present understanding of agriculture, NUE represents a question of process optimization in response to the increasing fragility of our natural resources base and threats to food grain security across the globe. Further improving nutrient use efficiency is a prerequisite to reducing production costs, expanding crop acreage into non-competitive marginal lands with low nutrient resources, and preventing environmental contamination. The nutrients most commonly limiting plant growth are N, P, K, S and micronutrients like Fe, Zn, B and Mo. NUE depends on the ability to efficiently take up the nutrient from the soil, but also on transport, storage, mobilization, usage within the plant and the environment. A number of approaches can help us to understand NUE as a whole. One involves adopting best crop management practices that take into account root-induced rhizosphere processes, which play a pivotal role in controlling nutrient dynamics in the soil-plant-atmosphere continuum. New technologies, from basic tools like leaf color charts to sophisticated sensor-based systems and laser land leveling, can reduce the dependency on laboratory assistance and manual labor. Another approach concerns the development of crop plants through genetic manipulations that allow them to take up and assimilate nutrients more efficiently, as well as identifying processes of plant responses to nutrient deficiency stress and exploring natural genetic variation. Though only recently introduced, the ability of microbial inoculants to induce NUE is gaining in importance, as the loss, immobilization, release and availability of nutrients are mediated by soil microbial processes.

Book excerpt: Non-linear regression was used to establish a correlation between the data generated from both methods, and to develop a model that can predict the 180-d N release curve for a specific EEF product based on the data from the accelerated lab extraction method. Based on the R2> 0.90 obtained for most EEF materials, results indicated that the data generated from the 74-h accelerated lab extraction method could be used to predict N release from the selected EEFs during 180 d, including those fertilizers that require biological activity for N release.
