Crop residues are sustainable feedstock for bioenergy production. The gross crop residue potential generated in India is 696.38 million tonnes/year. Cereal crops generate about 364.27 tonnes/year of residues. (rice, wheat, sorghum, pearl millet, maize), sugarcane and horticultural (coconut, areca nut, banana) found to have immense generation potential. 209.69 available as surplus can be explore...
To calculate the global warming potential of biogenic carbon dioxide emissions (GWPbCO2) associated with diverting residual biomass to bioenergy use, decay annual pulses into atmosphere over 100 years was compared between use for energy and its business-as-usual decomposition in agricultural, forestry, or landfill sites. Bioenergy increased atmospheric CO2 load all cases, resulting a 100GWPbCO2...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
This paper presents a spatially explicit method for making regional estimates of the potential for biogas production from crop residues and manure, accounting for key technical, biochemical, environmental and economic constraints. Methods for making such estimates are important as biofuels from agricultural residues are receiving increasing policy support from the EU and major biogas producers,...
Decomposition of rice straw residues and the emission CO2, CH4 under paddy crop rotation in Vietnamese Mekong Delta region – A microcosm study | Dung Tran Van, Thu Tat Anh, Long Vu Da Chau Thi Agricultural Journals
Beekeepers who use honey bees (Apis mellifera L.) for crop pollination services, or have colonies making honey on or in close proximity to agricultural crops, are concerned about the reductions of colony foragers and ultimate weakening of their colonies. Pesticide exposure is a potential factor in the loss of foragers. During 2009-2010, we assessed changes in the field force populations of 9-10...
The aim of this chapter is to describe the presence of pesticide residues in fruits and vegetables, mainly how they are introduced, dissipated, degraded, affected by food processing techniques and their risk assessment. Fruits and vegetables are important components of the human diet since they provide essential nutrients that are required for most of the reactions occurring in the body. A high...
The inappropriate or unlawful use of pesticides on agricultural crops can result in unacceptably high levels of these compounds, and their metabolites, in produce destined for human consumption. To protect the health of consumers, many countries stipulate Maximum Residue Levels (MRLs) for each pesticide compound in a range of fruit and vegetables. Worldwide, there are over 800 compounds current...
Temperate fruit crops are an important economic activity for growers in southern Brazil. However, several pest species are associated to apple (Malus domestica Borkh.) crops in Brazil. Pesticides are largely used to control them and one way to change this is to combine selective pesticides and predator insects. The goal of this research was to evaluate the effects of the abamectin, carbaryl, fe...
