Direct use of urine as fertilizer: potential risks of loading pharmaceuticals and hormones to field crops
(2019-04-11)
Ecological sanitation or Ecosan is an alternative approach to avoid the disadvantages of conventional water-based sanitation systems. This approach, based on ecosystem functioning and the closure of material flow cycles, ...
Spatial competition of learning agents in agricultural procurement markets
(2019-07-15)
Spatially dispersed farmers supply raw milk as the primary input to a small number of large dairy-processing firms. The spatial competition of processing firms has short- to long-term repercussions on farm and processor ...
Challenges and opportunities of using ecological and remote sensing variables for crop pest and disease mapping
(2019-07-15)
Crop pest and diseases are responsible for major economic losses in the agricultural systems in Africa resulting in food insecurity. Potential yield losses for major crops across Africa are mainly caused by pests and ...
Rice yield gaps in West Africa
(2019-05-15)
Rice is a staple food for many countries in Africa but the production has never satisfied the demand which largely depends on imports. Therefore, more efforts are needed for raising yield in order to reduce the gap between ...
Evaluation of 13C Mixed Triglyceride Breath Testing and Fecal Elastase 1 assays for the assessment of pancreatic function in babies with cystic fibrosis: Including an assessment of healthy babies to establish the range of normal for the 13C Breath test
(2019-02-19)
Evaluation of 13C Mixed Triglyceride Breath Testing and Fecal Elastase 1 assays for the assessment of pancreatic function in babies with cystic fibrosis (Including an assessment of healthy babies to establish ...
Suitability of non-destructive sensors for monitoring physiological and biochemical responses of tomato leaves and fruits to abiotic stresses
(2019-05-02)
The major aim of the present work was to proof the suitability of chlorophyll fluorescence-based indices to non-destructively monitor and predict changes in the content of plant compounds in response to abiotic stresses. ...
Importance of supplying dairy cows with essential fatty acids (EFA) and conjugated linoleic acids (CLA) during the transition period on metabolism and health
(2022-08-04)
Ketogenesis and steatosis are common sequelae of the severe mobilization of fat reserves necessary at the onset of lactation when the energy expenditures for milk and maintenance exceed the energy provided by voluntary ...
Agri-food policies and Sustainable Development Goals: Quantitative food system analyses
(2022-08-23)
The agricultural and food system is key to reaching several of the Sustainable Development Goals (SDGs), foremost those on food security (SDG2), reducing waste (SDG12), combatting climate change (SDG13), and reducing ...
Effect of blossom thinning on apple quality with conventional methods and study on laser application for selective thinning
(2022-09-27)
Crop-load regulation by blossom thinning has an important role to improve the fruit quality and mitigate an alternate bearing on apple fruit production. This method aims to reduce excessive flowers to regulate the final ...
Characterisation of the effect of redox potential on the emission of greenhouse gases using wireless sensing techniques
(2021-11-18)
Soils act as both a source and sink of greenhouse gases (GHGs) and are widely considered to contribute to global warming. Soil N2O emissions originate from microbial nitrification and denitrification processes. ...
