Digital assistance system as a holistic solution for site-specific and resource-saving crop protection

Digital Farming ermöglicht Softwaretools, mit denen Prozesse wie z. B. der Pflanzenschutz schon vor der Appli­kation von Pflanzenschutzmitteln (PSM) im Detail geplant und darauf basierend Entscheidungen getroffen werden können. Mit dem entwickelten Assistenzsystem wird genau dies für den Pflanzenschutz umgesetzt, und für die praktische Landwirtschaft zur Verfügung gestellt. Durch die Einbindung verschiedener Services wird die Erstellung von Applikationskarten ermöglicht und dabei verschiedenste Informationsquellen aus Webservices zur Verfügung gestellt. Der Dateninput besteht zunächst aus langjährigen Ertragsdaten, Zonenmanagementkarten, digitalen Höhendaten, Satellitendaten aber auch Sensordaten, die im Assistenzsystem prozessiert, vom Anwender ggf. auch nachbearbeitet werden können und vom Feldspritzgerät mit Hilfe des erzeugten Kartenmaterials teilflächenspezifisch appliziert werden. Das Assistenz­system begleitet den Anwender durch den gesamten Prozess – Planung, Vorbereitung, Applikation und Dokumentation – des Pflanzenschutzes. Dazu werden zum Beispiel mittelspezifische Abstandsauflagen, Anwenderschutzbestimmungen, das Driftminderungspotenzial der eingesetzten Technik, die aktuellen Witterungsbedingungen und weitere Informationen vom digitalen Assistenzsystem verarbeitet und bei den Empfehlungen berücksichtigt.Digital farming enables software tools with which processes such as plant protection can be planned in detail before the application of plant protection products (PPPs) and decisions can be made on this basis. The developed assistance system implements precisely this for plant protection and makes it available for practical farming. By integrating various services, the creation of application maps is made possible and a wide variety of information sources from web services are made available. The data input initially consists of long-term yield data, zone management maps, digital elevation data, satellite data and also sensor data, which are processed in the assistance system, can also be post-processed by the user if necessary and are applied by the field sprayer on a site-specific basis with the aid of the map material generated. The assistance system accompanies the user through the entire process – planning, preparation, application and documentation – of crop protection. For this purpose, for example, distance requirements specific to the medium, user protection regulations, the drift reduction potential of the technology used, the current weather conditions and other information are processed by the digital assistance system and taken into account in the recommendations

Assistance system for the site-specific use of herbicides

Die teilflächenspezifische Applikation von Herbiziden zur Unkrautbekämpfung ist ein Ansatz, mit dem eine Reduktion und Spezifikation angewendeter Pflanzenschutzmittel und somit eine umweltschonendere und nachhaltigere Agrarproduktion möglich wird. Im Rahmen des BLE-Projektes "Entwicklung und Praxistest eines Direkteinspeisungssystems ohne Verzögerungszeiten zur Teilflächenapplikation von Pflanzenschutzmitteln" konnte erstmals eine technisch ausgereifte Direkteinspeisungsfeldspritze genutzt werden, mit dieser die bislang bekannten Probleme der Direkteinspeisung gelöst wurden. Um mit dieser Technik jedoch eine tatsächliche Teilflächenapplikation unter Praxisbedingungen umzusetzen, bedarf es der zusätzlichen Entwicklung einer Systemumgebung, welche eine Vielzahl von satelliten-, sensor- und geodatengestützten Informationen über Schnittstellen integrieren kann und mit dessen Hilfe Teilflächen innerhalb der gesamten Applikationsfläche für unterschiedliche Applikationsmaßnahmen identifiziert und näher charakterisiert werden können. Zielsetzung ist die Entwicklung eines Assistenzsystems basierend auf der Direkteinspeisung zur orts- und zeitabhängigen teilflächenspezifischen Applikation von Pflanzenschutzmitteln. Erste Ergebnisse zeigen eine wirtschaftliche Kosteneinsparung und eine umweltschonendere Herbizideinsatz durch teilflächenspezifische Applikation.The site-specific application of herbicides for weed control is an approach that enables the reduction and specification of pesticides and thus a more environmentally friendly and sustainable agricultural production. Within the scope of the BLE project "Development and practical test of a direct feed system without delay times for partial area application of crop protection agents", a technically mature direct feed field sprayer could be used for the first time, which solved the previously known problems of direct injection. However, in order to implement an actual partial area application under practical conditions with this technology, it is necessary to additionally develop a system environment which can integrate a large number of satellite-, sensor- and geodata-supported information via interfaces and with the help of which partial areas within the entire application area can be identified and characterised in more detail for different application measures. The aim is to develop an assistance system based on direct feeding for the location- and time-dependent sub-area-specific application of pesticides

DEMMIN - Calibration and Validation Site for Remote Sensing

The presentation exemplify the challenge of complex environmental processors and the motivation for operational remote sensing test sites. Remote Sensing includes diverse e.g. platforms, sensors, methods for interpretation. The result is an urgent need for cal / val data from a number of environmental parameters. For the development of value-added information products based on remote sensing cal / dal data from a variety of environmental parameters are urgently needed. The test site DEMMIN has an operational automated measurement infrastructure that can provide the relevant in-situ-data for the calibration and validation of remote sesning

Remote sensing calibration and validation test site DEMMIN useable for hydrological applications

The calibration and validation test site DEMMIN is infrastructured for hydrological applications based on remote sensing.

DEMMIN – Teststandort zur Kalibrierung und Validierung von Fernerkundungsmissionen

With the "Global Monitoring for Environment and Security (GMES)" initiative the European Union (EU) and the European Space Agency (ESA) have established an ambitious program for using space borne remote sensing together with additional data sources and monitoring systems to provide innovative services for various environmental, economic, and security aspects in the context to the European market. To realize this objective, automated near real-time and real-time infrastructure has to be implemented for automated data processing of remote sensing data. The necessary development and implementation of the space segment and the ground segment is already well advanced. In contrast to this, the development of automated processing chains and processors for deriving value added products and especially the development of test sites for calibration and validation of remote sensing missions is in development. In our presentation we will present the DLR test site DEMMIN (Durable Environmental Multidisciplinary Monitoring Information Network) as a prerequisite for calibrating and validating e.g. remote sensing missions and sensors, data processing modules and processing chains, as well as remote sensing based value added data products on regional scale. For this background, the presentation gives an introduction to DLR’s test site DEMMIN with its specific regional characteristics, its in-situ measuring instrumentation and existing data base. Due to the cooperation of DLR with IG Demmin, the scientists receive support by the farmers and important information for their investigations. These are e.g. digital quasi-static data as soil maps, land parcel maps or digital dynamic data as yield maps, and application maps. Additional to the data base, an agro-meteorological weather network is installed in DEMMIN, which allows the automated measurement of all agro-meteorological parameters affecting the imaging process parallel to space borne or airborne remote sensing

Automated Generation of Value-Added Products for the Validation of Remote Sensing Information Based on In-Situ Data.

Available in-situ (IS) data are an essential prerequisite for the validation of remote sensing (RS) data and information products. Due to the fact that IS data supply is very labour- and cost-intensive, ground-truth data acquisition needs to be operational and automated. Moreover, measurements should be taken simultaneously to data acquisition by operational RS systems. To be able to deliver representative and validated IS data applied to the validation of complimentary operational RS data, locations of measurement stations will have to be optimised to be representative for a particular geographical space. This paper presents a novel approach to provide complementary IS data simultaneously to RS data acquisition. It outlines the installation and operation of an automated IS measurement network for environmental parameters in the DEMMIN (Durable Environmental Multidisciplinary Monitoring Information Network) test site. To process the data, an operational processing chain has been implemented and used for IS data volumes. IS data measurements are evaluated to establish a basis for generating and validating value-added RS products

Case management and care expertise as a prevention approach for adults with intellectual disabilities (FaPP-MgB) : study protocol for a randomized-controlled trial

Background: Adults with intellectual disabilities have a higher prevalence of unhealthy eating habits, stress, low levels of mobility, and comparable drug consumption as the general population. Consequently, they suffer from several chronic diseases earlier and more often, but there are fewer prevention and health promotion services including this population. The goal of this study is to determine if an advanced practice nursing approach in the community with home visits is an effective way to improve the health status of adults with intellectual disabilities. Methods: We will conduct a randomized-controlled trial with waiting list design in Hamburg, Germany. Inclusion criteria are diagnosis ICD F70-F79 and exclusion criteria are care level > 3 according to the German Social Code XI or being at the end-of-life. Participants will be block randomized. The intervention consists of advanced practice nurses performing case management, social space analysis, prevention planning, and counseling through four outreach home visits on nutrition, mobility, addiction, and stress. Comparison is usual care. The primary outcome is health status (WHODAS) after 12 months. Secondary outcomes are health-related quality of life (EQ-5D) and resilience (RS-11) after 6 and 12 months. The calculated sample size is 256 with an estimated dropout of 30%. Raters and analysts will be blinded. Analysis will be performed using ANCOVAs. Discussion: By providing case management and utilizing their nursing expertise, advanced practice nurses will provide valuable input and guidance on prevention and health promotion for people with intellectual disabilities. They will close the gap between health and social care, which is prominent in Germany, through cooperation between the existing care sectors. The findings will be disseminated in peer-reviewed journals and presented at national and international conferences.

The climate and soil moisture network at TERENO Northeastern German Lowland Observatory - DEMMIN

The goal of the TERENO initiative is the long-term monitoring and documentation of proposed climate change, changes in land use, social-economic developments and anthropogenic influences on terrestrial ecosystems. Therefore long-term observations of multitemporal environmental parameters at different scale are the basis for gathering information on changes of the available water resources, material flows, or further ecological changes. The Durable Environmental Multidisciplinary Monitoring Information Network (DEMMIN®) located in the North-east of Germany was installed by German Aerospace Center in 1999 for Calibration and Validation of Remote Sensing data at agricultural areas. Due to its physiographic composition and typical agricultural management the area is a perfect test site for monitoring of relevant environmental parameters. Since 2009 the DEMMIN test field of 50 x 50 km is part of the Northeastern German Lowland Observatory (TERENONE), which is coordinated by Helmholtz Centre Potsdam – GFZ German Research Centre for Geosciences. Because of the remote sensing focus of the DEMMIN test sites it is a perfect area to evaluate the potential of linking ground based in-situ data with remote sensing data analysis with view to the COPERNICUS initiative of the European Union (EU) and the European Space Agency (ESA)
