Collaborative project: Nitrogen Stabilization and Subsurface Placement as Innovative Technologies Enhancing the Resource Efficiency of Fertilized Urea - subproject 4 (Project)
...At three very different arable sites, the urea fertilization variants (1) standard, (2) stabilization and (3) placement were tested with respect to their effects on NH3 and N2O losses, yield parameters and N efficiency in the crop rotation winter oilseed rape winter wheat winter barley. ...Here, placement mostly resulted in increased N2O losses, while stabilization provided complex mitigation of all gaseous N losses. ...These will be successively developed, e.g. in the follow-up project StaPrax-Regio (started early 2021). ...

Vegetable cucurbits for nutrition-sensitive home and school gardens in Southeast Asia (Project)
...Micronutrient deficiency or hidden hunger affects more than 2 billion people worldwide (FAO 2008) and can exist in populations even where ghe food supply is adequate in terms of meeting energy requirements. Although these people are not considered hungry, their diets may be grossly deficient in one or more micronutrients.Cucurbits, specifically bitter gourd (Momordica charantia L.) and pumpkin (Cucurbita moschata L.) are an integral component of vegetable gardens in Asia. bitter gourd fruits are rich source of beta-carotene, vitamin C, folic acid, MG, P and K (Yuwai et al. 1991). ...

SPP 1090 AG 2: Mass balance of microbial biomass contribution to the formation of refractory soil organic matter using isotope tracer techniques – (cells, cell components,CO2, and NH4) (Project)
...Using tracer compounds labeled with isotopes, the experiments are focused on the microbial turnover rates and the formation of humic substances derived from bacterial biomass, fractionated cell components, and from mineralization products such as CO2 and NH4. The transformation of isotopically labeled constituents of bacterial biomass (14C; 13C; 15N) will be analysed in bioreactors with model soils of the research program. ...Results of preliminary experiments show evidence that carbon from CO2 contributes significantly to the formation of SOM. ...

A new concept for organic tomato breeding (Project)
...The first one is to test a new breeding strategy (F4 crossbreeds), which is well adapted to the growing system, and the second one is to select new sources of resistance by crossbreeding and verifying them. In the first approach, F4 crossbreeds created from breeding similar tomato lines should result in genetically partly heterogeneous populations, which can react more flexibly to stress factors. Commercial seeds will be produced from F4 crossbreeds, which should be of low phenotypic variance, however being genotypically diverse by possessing a part of heterogeneous gene loci. ...

Establishment of methods for the detection and characterisation of Clostridium difficile in food (Project)
...The disease is caused by toxins produced by C. difficile (enterotoxin A, cytotoxin B, binary toxin). ...C. difficile has also been isolated from healthy food-producing animals. ...Therefore, a method for the detection of C. difficile in food must be established and validated....
