This book was released on 2005 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The adoption of recommended management practices (RMPs) such as nitrogen (N) fertilization and cropping systems play important role in increasing crop residue production, with attendant increase in soil organic carbon (SOC) sequestration, agronomic productivity, and soil quality. This study was conducted with the objectives to evaluate the effect of long term N fertilization and cropping systems on: (i) SOC and soil organic nitrogen (SON) concentrations and pools, (ii) SOC sequestration rate (iii) soil quality determinants such as aggregation, total porosity and soil pH, and (iv) agronomic productivity and its relation with SOC pool. Replicated soil samples were obtained from a long-term experiment (23-yrs) at the Northwestern Illinois Agricultural Research and Demonstration Center, Monmouth, IL during Spring, 2004 up to a depth of 90 cm. The soil type is Muscatune silt loam (Fine-silty, mixed, superactive, mesic Aquic Argiudolls). The experimental design was split-split plot within a randomized complete block with three cropping systems [continuous corn (Zea mays) (CCC), and two rotation plots with corn and soybean (Glycine max) grown in alternate years (CSB and SBC respectively)] as the main plot, presence or absence of cover crop [oats (Avena sativa)] as sub plot and five N rates [0 (N0), 70 (N1), 140 (N2), 210 (N3) and 280 (N4) kg N ha−1] in the split-split plot arrangement. Results showed significant increase in both SOC and SON concentrations and pools by the addition of N fertilizers, with SOC pool ranging from 68.4 Mg ha−1 (N0) to 75.8 Mg ha−1 (N4), and SON pool ranging from 6.5 Mg ha−1 (N0) to 6.9 Mg ha−1 (N3) for 0-30 cm depth. The SOC sequestration rate over 23 years of N application ranged from 158 kg ha−1 yr−1 (N2) to 324 kg ha−1 yr−1 (N4) for 0-30 cm depth. Both soil bulk density (Pb) and C:N ratio significantly decreased with increase in the rates of N fertilizer for 0-30 cm depth. Continuous corn system, across all N treatments, sequestered 6 Mg ha−1 more SOC for 0-30 cm depth compared to corn-soybean rotation. Both water stable aggregates (WSA) and mean weight diameter (MWD) increased with increase in the rates of N, with mean WSA values ranging from 47 to 54% and MWD from 0.44 to 0.71 mm. The soils under CCC had more WSA (52.1%), which is 3% higher than that under corn-soybean rotation. The MWD values of cropping system treatments ranged from 0.5 to 0.65 mm, with the highest value corresponding to CCC. Both WSA (R2=0.23) and MWD (R2=0.32) were positively correlated with SOC concentration. The CCC system and increased rates of N fertilization increased corn residue (stover) yield, and thus the amount of biomass returned to the soil. However, N fertilization had no significant influence on soybean residue production. Regression analysis indicated a significant positive relationship between stover yield and SOC pool, but not between soybean residue yield and SOC pool. This study indicated that long-term continuous corn cultivation and judicious N fertilization are desirable management strategies for increasing SOC sequestration, enhancing soil physical quality , and improving sustainability of production systems.

This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the greatly increased productive capacity of current-day cropping systems, the shortcomings associated with conventional, high-intensity cropping systems and the growing threat of global climate change, warrant the identification of crop management practices that promote long-term agricultural sustainability and productivity. Unlike conventional cropping practices, which include synthetic nitrogen and pesticide use, alternative crop management practices, e.g., cover cropping, tillage reduction, organic amendment additions, and reducing or eliminating synthetic fertilizer use, have emerged as integrated and ecologically sound approaches to enhance agroecosystem functioning and services. Yet, mechanisms governing the differences in soil quality and crop yields among alternative cropping systems and conventional systems remain unclear. The aim of this dissertation study was to understand and quantify the mechanisms governing the relationship between carbon and nitrogen cycling and the interactions between plants, soil, and microorganisms within long-term conventional (annual synthetic fertilizer), low-input (alternating synthetic fertilizer and cover crop additions), and organic (annual manure- and cover crop additions) cropping systems, at the field-, soil pedon-, and micro-scales. A multi-scaled approach, including agronomic experiments, stable isotopes (13C and 15N), soil fractionation techniques, and microbiological analyses (e.g., functional gene quantification and phospholipid fatty acid assays), was employed to study mechanisms of soil carbon and nitrogen stabilization and loss and to draw links between microbial populations and carbon and nitrogen processing across different agroecosystems. Data from this research only partly corroborated the global hypothesis: the effects of long-term, low-input crop management enhance microbial-mediated carbon and nitrogen turnover in different soil microenvironments and optimize the balance between carbon and nitrogen stabilization and loss compared to the conventional and organic cropping systems. Only a weak relationship between short-term microbial community structure and long-term carbon and nitrogen sequestration was found across the three cropping systems. The conclusion drawn is that the effects of long-term crop management are dictated by complex trade-offs between soil carbon and nitrogen stabilization, microbial abundance and activity, nitrogen losses, crop productivity, and the quantity and quality of carbon and nitrogen inputs in alternative cropping systems.

This book was released on 2009-05-07 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture is the main occupation in India and about 75% of its population depends directly or indirectly on agriculture for their livelihood. It is the dominant sector that contributes 18% of the gross domestic product. Thus, agriculture is the foundation of the Indian economy. The maximum share of Indian exports is also from the agriculture sector. As the population of the country is increasing trem- dously, approximately at the rate of 19 million every year over the existing popu- tion of more than 1 billion (approximately 1. 18 billion), the food grain production must necessarily be increased. This can be done by increasing crop production to match the population growth rate of 2. 2% per annum, which is expected to stabilize at 1. 53 billion around 2050. There is no doubt that the Green Revolution in India during the late 1960s brought self-sufficiency in food grain production, mainly through the increase in rice and wheat crop yields – the two main crops of the country which play an important role from food security point of view. However, the excessive use of fertilizers and pesticides, and the neglect of organic manures for these crops, has resulted in the deterioration of physical, chemical and biological health of the ri- and wheat-growing soils. Owing to the deterioration of the health of these soils, the productivity of the rice–wheat cropping system has now either got reduced or in some places has become constant for the last decade.

Download or read book Carbon and Nitrogen Cycling in Soil written by Rahul Datta and published by Springer. This book was released on 2020-09-04 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several textbooks and edited volumes are currently available on general soil fertility but‚ to date‚ none have been dedicated to the study of “Sustainable Carbon and Nitrogen Cycling in Soil.” Yet this aspect is extremely important, considering the fact that the soil, as the ‘epidermis of the Earth’ (geodermis)‚ is a major component of the terrestrial biosphere. This book addresses virtually every aspect of C and N cycling, including: general concepts on the diversity of microorganisms and management practices for soil, the function of soil’s structure-function-ecosystem, the evolving role of C and N, cutting-edge methods used in soil microbial ecological studies, rhizosphere microflora, the role of organic matter (OM) in agricultural productivity, C and N transformation in soil, biological nitrogen fixation (BNF) and its genetics, plant-growth-promoting rhizobacteria (PGPRs), PGPRs and their role in sustainable agriculture, organic agriculture, etc. The book’s main objectives are: (1) to explain in detail the role of C and N cycling in sustaining agricultural productivity and its importance to sustainable soil management; (2) to show readers how to restore soil health with C and N; and (3) to help them understand the matching of C and N cycling rules from a climatic perspective. Given its scope, the book offers a valuable resource for educators, researchers, and policymakers, as well as undergraduate and graduate students of soil science, soil microbiology, agronomy, ecology, and the environmental sciences. Gathering cutting-edge contributions from internationally respected researchers, it offers authoritative content on a broad range of topics, which is supplemented by a wealth of data, tables, figures, and photographs. Moreover, it provides a roadmap for sustainable approaches to food and nutritional security, and to soil sustainability in agricultural systems, based on C and N cycling in soil systems.
