This book was released on 2017-11-19 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Biochemical Decomposition of Nitrogenous Substances in Soils From previous work in this laboratory 2 it has been shown that Hawaiian soils contain relatively greater amounts of amid and smaller amounts of basic (diamino acid) nitrogen than the vegetable proteins. From this it has been Sliggested that a study of the group Changes produced under the action of, bacteria might throw important light on both the availability of, and the nature of bacterial action on, nitrogenous fertilizers. Various factors, such as the degree of aeration, the acidity of the medium, the carbohydrates present, the synthesis of proteins in the body cells of the bacteria, the absorption of organic nitrogen compounds in varying degrees by plants, etc. SO complicate'the problem as to render very difficult an interpretation of 'the chemistry of bacterial action in soils. It has been Suggested, however, that by also studying the rates of decomposition under varying conditions some light might be thrown on this question.

Download or read book Predicting Nitrogen Mineralization in California Agroecosystems written by Kenneth Stuart Miller (Jr.) and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns over the fate of excess nitrogen (N) from fertilizers in California agroecosystems has prompted the need for more accurate N budgets. While many growers have adopted decision support tools to improve fertilizer use efficiency, these tools often overlook the N released from soil organic matter (SOM) through mineralization (N[subscript min]), which can contribute significant quantities of crop available N over a growing season. While methods exist for assessing the N[subscript min] potential of soils, they are often time consuming and impractical. Furthermore, attempts to model N[subscript min] have revealed the need for regional specificity. The goal of this study was to develop a predictive model for N[subscript min] from native SOM (no organic amendments) based on soil properties and temperature in California soils for real-time decision making and improved N fertilizer use efficiency. In the spring of 2016 and 2017, undisturbed soil cores (4.5 cm x 15 cm), representative samples, and samples for a greenhouse trial were taken from 57 soils under annual crop rotations in productive growing regions throughout central and northern California, including the Sacramento, San Joaquin, and Salinas Valleys, as well as Sacramento River Delta and Tulelake Basin. Cores were incubated at 3 temperatures, 5, 15, and 25 °C, for 10 weeks at 60% water-filled pore space before being analyzed for final mineral N (ammonium-N and nitrate-N). Representative soil samples were analyzed for a number of soil properties, including initial mineral N (N[subscript int]), total carbon (C[subscript total]), total N (N[subscript total]), particulate organic matter C (C[subscript POM]), particulate organic matter N (N[subscript POM]), permanganate oxidizable C (C[subscript POX]), microbial biomass C (C[subscript mic]), fluorescein diacetate hydrolysis (FDA), pH, electrical conductivity (EC), texture, bulk density (p[subscript b]), water holding capacity (WHC), and dithionite and pyrophosphate extractable iron (Fe[subscript d] and Fe[subscript p], respectively). Nitrogen mineralization was calculated by subtracting Nint from the final mineral N. Stepwise multivariate regression was used to select soil properties for generation of a predictive model of N[subscript min]. In greenhouse trials, soils (0.8 – 1.5 kg) were mixed with sand (2:1 soil:sand), planted with tall fescue (Festuca arundinacea var. Cajun II), and grown for ~218 days with intermittent harvests to track N uptake over time. These trials served as a validation of the incubation derived model and to assess plant influences on N[subscript min]. Stepwise regression was also conducted on greenhouse obtained N[subscript min] values. Nitrogen mineralization ranged from 10.5 to 133.7 mg kg−1 at 25 °C, and 0.24 to 6.1 % of N[subscript total]. Generally, N[subscript min] was greater in soils from the Delta and Tulelake regions as compared to the other regions. The temperature response of N[subscript min] was similar across all soil types and was fit with an S-shaped curve. Concerning modeling, Akaike Information Criterion suggested that two separate models should be created; one for high SOM soils (SOM[subscript high]; > 3%) and one for low SOM soils (SOM[subscript low];

This book was released on 2017-10-27 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Assimilation of Nitrogen by Rice In the process of nitrification ammonia represents one stage in the oxidation of organic nitrogen, and if conditions are not favorable for complete oxidation, the process may end at this point. In arable soils it is not infrequent to find rather large quantities Of ammonia. Fraps,1 for instance, found that the ammonia content Of some Texas soils exceeded the nitrates, and that the application of certain Organic nitrogenous fertilizers resulted in the accumulation in the soil of greater quantities Of ammonia than of nitrates. This author refers to active nitrogen as including both nitrates and ammonia, and points Out that in considering the available nitrogen Of soils, greater atten tion should be given to ammonia.

Available in PDF, EPUB and Kindle. Book excerpt: The practice of biotechnology, though different in style, scale and substance in globalizing science for development involves all countries. Investment in biotechnology in the industrialised, the developing, and the least developed countries, is now amongst the widely accepted avenues being used for economie development. The simple utilization of kefir technology, the detoxification of injurious chemical pesticides e.g. parathion, the genetic tailoring of new crops, and the production of a first of a kind of biopharmaceuticals illustrate the global scope and content of biotechnology research endeavour and effort. In the developing and least developed nations, and in which the 9 most populous countries· are encountered, problems concerning management of the environment, food security, conservation of human health resources and capacity building are important factors that influence the path to sustainable development. Long-term use of biotechnology in the agricultural, food, energy and health sectors is expected to yield a windfall of economic, environmental and social benefits. Already the prototypes of new medicines and of prescription fruit vaccines are available. Gene based agriculture and medieine is increasingly being adopted and accepted. Emerging trends and practices are reflected in the designing of more efficient bioprocesses, and in new research in enzyme and fermentation technology, in the bioconversion of agro industrial residues into bio-utility products, in animal healthcare, and in the bioremediation and medical biotechnologies. Indeed, with each new day, new horizons in biotechnology beckon.
