The residual effects of crop residues on N availability and crop growth are largely unknown. A field experiment was conducted from 1986 through 1988 at Lincoln, NE, to determine the residual effects on no-till corn (Zea mays L.) production and N uptake of 0,50, 100, and 1509'0 of the amount of crop residues produced by the previous crop during the previous 5 yr. These effects were evaluated wit...

The corn crop is one of the most important crops worldwide. However, management residues generated not efficient enough, which diminishes competitiveness this crop. An interesting option for valorization these wastes their thermal use. In order to make residue as much possible, it vital know different processes related a harvest, and try adapt use waste depending on its characteristics. Thus, i...

rose water residues are by-products of rose water industries. these residues do not have any industrial usage and they are returned to soil as crop fertilizer. in this research, the effects of adding rose water distillation residues to soil in different particle sizes and weight proportion were investigated and changes in mechanical strength, and water holding capacity of soil and the growth of...

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,...
