Managing Agricultural Residues


Book Description

Many agriculturalists, conservationists, and environmentalists are stressing the importance of sustaining soil productivity so that future generations will have adequate productive land on which to produce food. One significant factor affecting soil productivity is the retention of crop residues on the surface of the soil to help control soil erosion. This book provides a review of the vast amount of literature on the subject, condensing the findings in a comprehensive, easy-to-understand manner. It focuses on topics such as erosion control, crop production in systems involving surface residues, residue use for fuel and animal feed, plant pathogens, insects, soil properties, and the economics of conservation tillage.

The first section contains the introductory chapter from the editor. The second section is related to the preparation of fertilizers and compost for soil amelioration from agricultural residues and waste water. The third section considers the use of agricultural waste for solid biofuels and biogas. The fourth section discusses sustainability and risk assessment related to the use of agricultural waste and residues.




Analysis of Chemical Residues in Agriculture


Book Description

Analysis of Chemical Residues in Agriculture presents a focused, yet comprehensive guide on how to identify, evaluate and analyze the wide range of chemicals that impact our food production system. The book presents a variety of analytical technologies and methods in order to help professionals, researchers, and graduate and undergraduate students understand chemical residues in agriculture and apply them to applications for the detection and quantification of chemical residues – both organic and inorganic – in several agricultural matrices, including crops, fruits, meat, food, feed, soil and water. Agriculture remains one of the most strategic sectors for the global economy and well-being. However, it is seen as a source of environmental and health concerns mainly due to the high amount of pesticides and fertilizers used in production systems around the world; moreover, a thorough understanding of the topic is necessary when we consider livestock production systems also apply large amounts of veterinary drugs to treat illness and promote increases in productivity. - Identifies the main scientific and technological approaches of analytical chemistry dedicated to agricultural and related matrices to solve real problems and for R&D purposes - Provides a description of the analytical technologies and methodologies used to reduce the negative impact of several agrochemicals on the environment and health - Explores cutting-edge analytical technologies to detect residues in agricultural and related matrices




Biofuels from Agricultural Wastes and Byproducts


Book Description

Traditional agriculture and emerging biofuels technology produce anumber of wastes and by-products, ranging from corn fiber andglycerin to animal manure, that have the potential to serve as thebasis for additional sources of bioenergy that includes both liquidbiofuels and biogas. Biofuels from Agricultural Wastes and Byproducts isthe first book to focus solely on the production of biofuelsprimarily from agricultural waste and by-products. The book isdivided roughly into two sections. The first section looks atliquid biofuel production from agricultural byproducts,densification of agricultural residues, and the delivery from farmto processing plant of waste and byproducts for use in biofuelproduction. The second section focuses on anaerobic digestion offood and animal wastes, microbial diversity, molecular andbiochemical aspects of methanogensis. Together these sections solidify Biofuels fromAgricultural Wastes and Byproducts as a definitive source ofinformation on the use of agricultural waste and by-products inbiofuel production.




Biotransformation of Agricultural Waste and By-Products


Book Description

Biotransformation of Agricultural Waste and By-Products in the 4F Economy: The Food, Feed, Fiber, Fuel (4F) Economy presents an evaluation of plant species better exploitable for a particular transformation. As crops are already covering large parts of cultivable soils, is it is not conceivable to try to extend the cultures beyond the limit of available soils, but a further increase in productivity is not easy to obtain. The book discusses advances in technology and plants design which support the exploitation and valorization of vegetable and fruit by-products through fermentation (feed-batch liquid fermentation, solid-state fermentation) in bio-based bio-chemicals/biofuels production. Pathways in the biosynthesis of fibers, sugars, and metabolites are provided with a focus on the lifecycle of bacteria, yeasts, and even plant species. The text analyzes cellular structures and the organization of cell walls in order to show which polysaccharides offer more favorable fermentative processes and which are detrimental. - Provides an overview of all plant based biosources - Includes examples of biochemical/biofuel production from plant waste - Discusses the production of enzymes used in the plant fermentation processes - Explores the new fermentation technologies and production of chemicals and fuels from various plants




Biotechnology for Agro-Industrial Residues Utilisation


Book Description

Residues from agriculture and the food industry consist of many and varied wastes, in total accounting for over 250 million tonnes of waste per year in the UK alone. Biotechnological processing of these residues would allow these waste products to be used as a resource, with tremendous potential. An extensive range of valuable and usable products can be recovered from what was previously considered waste: including fuels, feeds and pharmaceutical products. In this way Biotechnology can offer many viable alternatives to the disposal of agricultural waste, producing several new products in the process. This book presents up-to-date information on a biotechnology approach for the utilisation of agro-industrial residues, presenting chapters with detailed information on materials and bioconversion technology to obtain products of economic importance: The production of industrial products using agro-industrial residues as substrates The biotechnological potential of agro-industrial residues for bioprocesses Enzymes degrading agro-industrial residues and their production Bioconversion of agro-industrial residues. Written by experts in Biotechnological processing of Agro-Industrial Residues, this book will provide useful information for academic researchers and industry scientists working in biotechnology, waste management, agriculture and the food industry.

Renewable Energy Production from Energy Crops and Agricultural Residues


Book Description

Energies is open to submissions for a Special Issue on “Renewable Energy Production from Energy Crops and Agricultural Residues”. Biomass represents an important source of renewable and sustainable energy production. Its increasing consumption is mainly related to the increase in global energy demand and fossil fuel prices, but also to a lower environmental impact compared to non-renewable fuels. These factors take RED II directives into consideration. In the past, forestry interventions were the main supply source of biomass, but in recent decades two others sources have entered the international scene. These are dedicated energy crops and agricultural residues, which are important sources of biomass for biofuel and bioenergy. Below, we consider four main value chains: • Oil crops: Oil production from non-food oilseed crops (such as camelina, Crambe, safflower, castor, cuphea, cardoon, etc.), oil extraction, and oil utilization for fuel production. • Lignocellulosic crops: Biomass production from perennial grasses (miscanthus, giant reed, switchgrass, reed canary grass, etc.), woody crops (willow, poplar, Robinia, eucalyptus, etc.), and agricultural residues (pruning, maize cob, maize stalks, wheat chaff, sugar cane straw, etc.), considering two main transformation systems: 1. Electricity/heat production 2. Second-generation ethanol production • Carbohydrate crops (cereals, sweet sorghum, sugar beets, sugar cane, etc.) for ethanol production. • Fermentable crops (maize, barley, triticale, Sudan grass, sorghum, etc.) and agricultural residues (chaff, maize stalks and cob, fruit and vegetable waste, etc.) for production of biogas and/or biomethane.
