Bedding material properties and slurry C/N ratio affect the availability of nitrogen in cattle slurry applied to soil

Published in Frontiers in Sustainable Food Systems

Introduction Cattle slurry used as fertilizer in crop production is a mix of feces, urine, water, and bedding material from the housing system. Previous studies have shown that slurry nitrogen (N) availability to crops is dependent on C/N ratio. As the bedding material can contribute a significant part of total slurry carbon (C), its characteristic...

Characterization and valorization of biogas digestate and derived organic fertilizer products from separation processes

Published in Frontiers in Sustainable Food Systems

Introduction Anaerobic digestion of manure, together with other biowastes, produces biogas that can substitute fossil energy and thereby reduce CO2 emissions and post- digestion greenhouse gas emissions. The final digestate of the process is an organic fertilizer rich in plant nutrients and recalcitrant organic constituents. The digestate character...

Published in Ecological Chemistry and Engineering S

This study demonstrates that the process of mushroom production, from straw acquisition through substrate preparation to mushroom harvesting, and the utilisation of the remaining biomass as a valuable soil conditioner allows for minimising residue and reducing the use of mineral fertilisers It helps fill the gaps in the currently deficient manure i...

Minor straw return enhances net income in a maize-wheat rotation system

Published in Frontiers in Environmental Science

Straw returning to the field is a common agricultural practice in China. Nevertheless, in the maize-wheat rotation system of the semi-arid region in Northwest China, it is essential to investigate the optimal approach for coupling straw return and fertilization in order to enhance soil quality and crop yield. A field trial conducted in the semi-ari...

Published in Frontiers in Sustainable Food Systems

Anaerobic digestate is a nutrient rich slurry by-product derived from biogas production, often used as a fertiliser due to its high nitrogen content. However, nitrogen losses from its application can lead to environmental pollution. In a laboratory experiment, the addition of high organic carbon materials to digestate-amended soil as a potential me...

Control measure of sweet potato weevil (Cylas formicarius Fab.) (Coleoptera: Curculionidae) in endemic land of entisol t...

Published in Open Agriculture

Sweet potato weevil Cylas formicarius (Fab.) is the main obstacle for sweet potato production in various countries. Root damage caused by C. formicarius larvae reduced root yield up to 100%. The aim of this study is to test the measures using mulch and entomopathogenic fungus Beauveria bassiana for controlling C. formicarius in endemic land of enti...
