Non-invasive sensor technologies for estimating the population of Heterodera schachtii on the leaves of sugar beet (Project)
To keep nematode populations at tolerable densities several factors (crop rotation, variety, intercropping) have to be taken into account simultaneously in order to avoid yield losses or increased resource input. Soil samples from large areas are economically not practical. The objective of this project is to test the feasibility of whether the soil abundance of the nematode can be derived from...

Assessment and differentiation of abiotic stresses using volatile indicators (Project)
The aim of project ZS3 is the early detection and differentiation of abiotic stresses (drought and nutrient deficiency) with non-destructive and destructive methods, before the emergence of visible symptoms. Nitrogen monoxide, ethane and ethylene production in the plant will be analysed to determine their use for early stress detection. Furthermore, a reference analysis will be developed to...

More than a niche? The potential of dam rearing for marketing of milk and male calves (Project)
Consumers as well as animal rights organisations criticise repeatedly the early separation of cow in calf in modern dairy farming. Meanwhile, some dairy farms rear their calves by suckling at dam or foster cows, and studies address the effects of cow-calf contact on animal health and performance. However, until now information is lacking how milk and calves, which are produced in such systems,...

Detection of soil heterogeneity in breeding plots and field experiments (Project)
This project aims to detect small scale soil heterogeneity in plot and field experimentation in a simplified way by using non-contacting passive and active sensor systems. This information should contribute to optimized experimentation and further allow to analyze complex genotype-soil interactions. The sensors used include mobile VIS-NIR sensors for the measurement of C, N and soil texture in...

Sensor based detection of patterns of nutrient contents and nutrient availability in soil (Project)
Soil use and management is usually done uniformly within an arable site, independent of its size (< 1 - > 100ha). Activities are based on analyses that more or less represent average values for the corresponding site. But, in reality almost all soil characteristics reveal a distinct within field variability so that a uniform management does not meet the requirements for many parts of the site....

Non-invasive characterization of plant stress at the field scale (Project)
Soil electrical conductivity (EC) is a sensor-based measurement that is recognized as the most valuable indirect indicator of soil physical and chemical parameters (Sudduth et al. 2001; Sudduth et al., 2003; Corwin 2008). Due to the fact that the geological underground is heterogeneous, geophysics can only attempt to represent an imaginary homogeneous half-space of the real world. To represent an...

Identifying drought stress in the soil root zone by NMR imaging and relaxometry (Project)
The project aims to characterise the influence of spatial heterogeneities of the soil on root water uptake (RWU) processes under stress scenarios.

Fluorescence image analysis of leaf compounds (Project)
A multicolour fluorescence imaging analysis system will be established. The aim is the non-destructive, fast and cost-efficient analysis of crop plants and their products. In the medium and long term this should replace the conventional chemical analysis for detection of health as well as biotic and abiotic stress factors.

Non-invasive detection and discrimination of biotic and abiotic stress factors in barley and sugar beet by means of highly-resolved spatial and temporal fluorescence techniques for efficient breeding programmes and crop management (Project)
Fluorescence techniques are used in plant physiological research with the aim of characterizing specificities of the photosynthesis process and their changes when plants are exposed to stress situations. However, the common methods are not stress-specific and do not allow differentiation between multiple stresses. In this context, new techniques have been developed such as Laser induced...

Non-invasive determination of water and salt content with a portable microwave resonator (Project)
Based on the dual-mode sensor technology introduced by EMISENS, a portable and battery powered handheld device for the investigation of crops and grapes will be developed and optimized. This method allows for extremely fast and non-invasive measurements of the complex dielectric permittivity of plant tissue at two different frequencies in the range from 100 MHz to 3 GHz, which will enable the...
