Available in PDF, EPUB and Kindle. Book excerpt: Biochar is considered as a soil amendment to improve the resilience and productivity of agricultural systems. In particular, co-application of biochar and nitrogen (N) fertilizer has the potential to reduce N losses compared to applying synthetic N alone. However, the positive effects of biochar amendment are tightly linked to several factors. Our overall objective was to determine the effect of biochar types, application methods, and biochar rate on soil health, especially on soil N dynamics, and forage production through bench - and field-scale experiments. A 60-day bench-scale experiment was conducted to study the effect of amending soil with the two types of biochar using two application methods on soil N transformation. This experiment consisted of four treatments (control, 150 mg N kg−1 biochar, 150 mg N kg−1 urea, 75 mg N kg−1 urea + 75 mg N kg−1 biochar) with two application methods (surface application and incorporation). When biochar and urea were co-applied, biochar with higher cation exchange capacity inhibited nitrification and biochar with higher ash content reduced nitrous oxide (N2O) emission compared to urea alone. Biochar applied on soil surface increased 47% mineral N concentration and reduced 20% N2O emission compared to biochar mixed with soil. A two-year field experiment was conducted in a pasture system in Middle Tennessee to determine the effect of biochar rates (0 to 22.5 Mg ha−1) on forage production and soil properties. Biochar was surface applied in April 2017. Soil samples were collected from 0-15 cm depth biannually beginning June 2017 and plant harvest was done in May 2017 and 2018. Results showed that >18 Mg ha−1 biochar rate significantly affected soil properties and 9 Mg ha-1 was the most profitable rate based on the cost-benefit analysis. Also, biochar addition reduced 38-53% soil mineral N within six months while increased 16-22% soil organic carbon and 12-21% extractable phosphorus within two years compared to no biochar addition. Biochar did not increase forage yield but increased plant potassium uptake by 16-26% in 2017. In conclusion, biochar exhibited positive impacts on soil quality, but these effects were influenced by biochar characteristics, application method, and biochar rates.

Download or read book Biochar as Soil Amendment written by José María De la Rosa and published by MDPI. This book was released on 2020-03-10 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The role of biochar in improving soil fertility is increasingly being recognized and is leading to recommendations of biochar amendment of degraded soils. In addition, biochars offer a sustainable tool for managing organic wastes and to produce added-value products. The benefits of biochar use in agriculture and forestry can span enhanced plant productivity, an increase in soil C stocks, and a reduction of nutrient losses from soil and non-CO2 greenhouse gas emissions. Nevertheless, biochar composition and properties and, therefore, its performance as a soil amendment are highly dependent on the feedstock and pyrolysis conditions. In addition, due to its characteristics, such as high porosity, water retention, and adsorption capacity, there are other applications for biochar that still need to be properly tested. Thus, the 16 original articles contained in this book, which were selected and evaluated for this Special Issue, provide a comprehensive overview of the biological, chemicophysical, biochemical, and environmental aspects of the application of biochar as soil amendment. Specifically, they address the applicability of biochar for nursery growth, its effects on the productivity of various food crops under contrasting conditions, biochar capacity for pesticide retention, assessment of greenhouse gas emissions, and soil carbon dynamics. I would like to thank the contributors, reviewers, and the support of the Agronomy editorial staff, whose professionalism and dedication have made this issue possible.
Download or read book Biochar for Environmental Management written by Johannes Lehmann and published by Routledge. This book was released on 2012-05-16 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biochar is the carbon-rich product when biomass (such as wood, manure or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its stability in soil and superior nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process. This book is the first to synthesize the expanding research literature on this topic. The book's interdisciplinary approach, which covers engineering, environmental sciences, agricultural sciences, economics and policy, is a vital tool at this stage of biochar technology development. This comprehensive overview of current knowledge will be of interest to advanced students, researchers and professionals in a wide range of disciplines.

Download or read book Sustainable Agriculture Reviews 61 written by Shah Fahad and published by Springer Nature. This book was released on 2023-04-13 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book aim to contribute the latest understandings of physiological, biochemical and molecular bases of the responses of major crop plants to a range of different biomass produced biochar to introduce climate resilience crop varieties which leads to enhanced crop productivity and quality under stressful conditions and also for better utilization of natural resources to ensure food security through modern breeding. Finally, this book will be a valuable resource for future plant stress related research with biochar, and can be considered as a reference book for front-line researchers working on sustaining crop production under climate change. Adverse effects of climate changes on crops has developed the situation quite critical for sustainable agriculture. Food security has become in danger due to low production of agricultural crops by resilient climate and ever increasing human population. Heat, drought, salinity, soil compaction, flooding and poor soil organic carbon induced stress in crops by climate adverse conditions are major concerns in this regard. A mechanistic understanding of the interactions between abiotic stresses response of crops is needed to identify and take advantage of acclimation traits in major crop species as a prerequisite for securing robust yield and good quality. This underpins a need for crops with inherent yield increase, yield stability against multiple abiotic stresses and improved quality. Individual stress tolerance mechanisms have been well documented so far. However, mechanisms behind plants’ tolerance by application of biochar and its interactions with soil and plant roots towards multiple abiotic stresses are not fully understood. In addition, there will always be some uncertainty associated with modelling the complex relationships between agricultural yields, product quality with biochar under future climate scenarios. Prediction of yield and quality stability, one of most complex agronomic traits, must integrate aspects of plant development, physiology, biochemistry and genetics. Furthermore, the GxExM interactions will complicate the model predications, thus the responses of a given genotype to a defined environment under certain management strategy need to be determined empirically and used to parameterise and refine crop models.
Download or read book Biochar and the Soil Nitrogen Cycle written by Daniel Norman Dempster and published by . This book was released on 2013 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: [Truncated abstract] Methods of sequestering carbon (C) are being investigated to mitigate the current trend of increasing atmospheric carbon dioxide concentration. Furthermore, since the onset of intensive farming practices soil organic matter (SOM) content has declined in many soil types throughout the world. The application of pyrolysed organic matter, or biochar, to soil can maintain higher soil C. The application of biochar to soil has also been shown to potentially improve soil fertility and enhance yields of crops such as maize, wheat and peanuts. However, biochar amendment changes many soil properties but the mechanism by which biochar alters soil processes and plant growth is not always clear. This thesis focuses primarily on those changes that are directly linked to the soil nitrogen (N) cycle. Biochar has been reported to have a large nutrient and water retention capacity; which may cause decreases in N leaching with its application to soil. Biochar can contain labile C and is also highly porous, potentially providing a substrate for microbial utilisation and a habitat for microbial colonisation. Biochar addition to soil can increase microbial abundance and activity. Previous research has hypothesised that this may be responsible for enhanced N mineralisation rates that contribute to the demonstrated improvements of N fertiliser use efficiency (up to 90%) in glasshouse-based agronomic research. The sandy soils that are widespread throughout the broadacre agricultural region of Western Australia (WA) naturally have low water (2-10% v/v) and nutrient retention capacities and low SOM content. Thus the sandy soils of WA are an environment in which biochar amendment is likely to influence soil N cycling. This provided the premise for the investigation into how biochar interacts with the soil N cycle (mineralisation, nitrification, immobilisation, N sorption, leaching, and plant N uptake) in coarse-textured soils of Western Australian broadacre agriculture...
