Crop Residues for Sustainable Livestock production

Liquefaction of Crop Residues for Polyol Production

The liquefaction of crop residues in the presence of ethylene glycol, ethylene carbonate, or polyethylene glycol using sulfuric acid as a catalyst was studied. For all experiments, the liquefaction was conducted at 160°C and atmospheric pressure. The mass ratio of feedstock to liquefaction solvents used in all the experiments was 30:100. The results show that the acid catalyzed liquefaction pro...

Sustainable intensification of crop production

Relevance Concerns about the environmental impact of farming has increasingly been the focus of discussions in the EU. Croplands, a primary land use in Europe, have a significant impact on the environment (soil, water bodies, global climate, local biodiversity and human health). The use of fertilisers and pesticides associated with conventional farming may lead to pollution and/or climate chang...

Bacterial Biofertilizers for Sustainable Crop Production: a Review

The most important constraint limiting crop yield in developing nations worldwide, and especially among resource-poor farmers, is soil infertility. Therefore, maintaining soil quality can reduce the problems of land degradation, decreasing soil fertility and rapidly declining production levels that occur in large parts of the world needing the basic principles of good farming practice. Minerals...
