One of the most effective naturally occurring insecticide powders is diatomaceous earth (DE), which contains above 96 % of silica (silicon dioxide SiO2). In recent days, the possibility to use new improved DE formulations for plant protection in horticulture has been the focus of research. For aphids and other under-leaf insects only insecticides deposited on leaf undersides are effective. We tested electrostatic application of different silica containing dusts onto the cruciferous crop pak-choi (Brassica chinensis). The materials tested were Fossil Shield 90.0s, Advasan, Biobeck PA910, and a formulation newly developed by the Urban Horticultural Section at Humboldt University called "Al-06". Silica materials were tested for their effect on plant photosynthesis and efficacy against the mustard beetle (Phaedon cochleariae F.). All materials have been effective in contact experiments against tested insects. However, significant differences were observed between materials after application onto plant leaves. Fossil Shield, Advasan, and Al-06 application resulted in a good coverage and in high protection against the mustard beetle. Biobeck PA910 was easily removed by wind from leaf surfaces and did not protect the plants well. However, photosynthesis has been reduced in treated plants and remained at a lower level even after dust removal. Experimental results are critically discussed in the view of future potential for crop protection programs.

Source-separated, nitrified, and decontaminated human urine constitutes a promising plant fertilizer that contains a large share of the nitrogen and phosphorus in household wastewater, and other plant nutrients. However, human urine contains high levels of sodium and chloride that can affect salt-sensitive greenhouse crops. Replacing mineral fertilizer with nitrified urine fertilizer could reduce the environmental impact of lettuce production in hydroponic systems, if marketable yield, appearance, and produce quality are not affected. In the present study, a treatment combination of a nitrified urine fertilizer and mineral fertilizers was used to grow lettuce through the nutrient film technique. This was compared to a conventionally fertilized control treatment. No significant differences were observed regarding yield, phenotype, and contents of nitrate, heavy metals, phenolic acids, and chlorophyll in leaf tissue. Calcium content was significantly reduced and sodium was elevated in nitrified urine treatment. For the elements nitrogen, phosphorous, and potassium, a saving of 48%, 13%, and 15% was calculated, respectively. The calculated carbon footprint from the total fertilizer production was reduced by 20.52%, caused by the nitrified urine treatment. Based on these results, a nutrient solution composed of nitrified urine fertilizer combined with mineral fertilizer may be a promising alternative for growers to produce lettuce with a reduced environmental impact without loss of plant quantity and quality.

Controlled environment agriculture is a promising alternative to conventional production methods, as it is less affected by climate change and is often more sustainable, especially in circular and recycling frameworks such as aquaponics. A major cost factor in such facilities, however, is the need for skilled labor. Depending on available resources, there are endless possibilities on how to choose ingredients to realize a desired nutrient solution. At the same time, the composition of the desired solution is subject to fluctuations in fish water quality, fertilizer availability, weather, and plant development. In high-evaporation scenarios, e.g., summer, nutrient solutions might be mixed multiple times per day. This results in a complex, multi-variable task that is time-consuming to solve manually, yet requires frequent resolution. This work aims to help solve this challenge by providing methods to automate the nutrient mixing procedure. A simple mass-balance-based model of a nutrient mixing tank with connections to different water sources, drains, and fertilizers is provided. Using methods of static optimization, a program was developed which, in consideration of various process constraints and optimization variables, is able to calculate the necessary steps to mix the desired solution. The program code is provided in an open-source repository. The flexibility of the method is demonstrated in simulation scenarios. The program is easy to use and to adapt, and all necessary steps are explained in this paper. This work contributes to a higher automation level in CEA.

Artificial neural networks (ANN) have been successfully used for modelling climate and plant signals in greenhouses. This work shows the combination of two ANN models, built and trained separately, and then coupled together. Both models were trained using a data set consisting of 3 complete cultivation periods (2011 until 2013) of 2 venlo-type greenhouses located at the Humboldt-Universitat zu Berlin. The greenhouses were used for soilless cultivation of tomato. The first model considered (climate prediction: CP) estimated the expected values of temperature and relative humidity in the near future (one-step prediction, OSP). The output was then recursively fed to the model in order to make further predictions. Each time step represented 5 min, and the maximum number of prediction steps was set to 6. On the other hand, the output of the second model (plant signals: PM) was not a prediction in time, but an estimation of plant signals (leaf temperature, transpiration rate, photosynthesis rate) as expected to be measured by a phytomonitoring system (BERMONIS). The combined models took the 6 predicted steps of climate (long-term prediction: LTP) produced by CM and used them to feed PM, thus generating a Biosignals LTP. As expected, the fit of the LTP decreased with the number of forward steps. For example, the R2 for leaf temperature range from 0.946 for the first simulation until 0.704 for the 6th simulated step. For transpiration and photosynthesis rate, these ranges were (0.874, 0.809) and (0.772, 0.692), respectively. These results show that the estimated plant responses could support a predictive control system, in order to avoid plant damage due to extreme climate conditions.

Die Genauigkeit der N min -Analyse hangt wesentlich von der Anzahl der Einstiche zur Herstellung der Mischprobe ab. Empfohlen werden bei einer Flachengrose von einem Hektar 16 Einstiche, allerdings wird hierbei von einer Bodenprobenahme vor Kulturbeginn im zeitigen Fruhjahr ausgegangen. Im Rahmen der novellierten Dungeverordnung (DuV) ist auch eine Bodenbeprobung vor einer Zweit- oder Drittkultur vorgesehen, so dass mit einer groseren Heterogenitat aufgrund der Vorkultur und nicht umgesetzten Ernteresten gerechnet werden muss. Weitere Effekte sind aus der Bodenart, der Bewirtschaftungsform, der verabreichten Dungermenge und -art sowie zufalligen Effekten zu erwarten. Im Rahmen eines Modell- und Demonstrationsvorhabens zur Umsetzung der DuV im Gemusebau wurden in der Region Rheinland-Pfalz auf 10 Schlagen von konventionell und biologisch arbeitenden Betrieben an drei verschiedenen Zeitpunkten Bodenproben in 2 Tiefen (0-30 und 30-60 cm) entnommen. Ausgehend vom Rastermas 150 m fur die Standardbeprobung wurden diagonal im Abstand von ca. 15 m jeweils 25 Einzelproben entnommen und getrennt analysiert. Die Termine der Probenahmen waren vor der Dungung, 4 Wochen nach der Dungung und nach der Ernte. Grundsatzlich verringert sich der Variationskoeffizient (cv) mit der Anzahl der verwendeten Einstiche je Schlag und liegt in der Regel mit 4 Einstichen bei unter 50% und mit 10 Einstichen bei unter 25%. Auf einzelnen Schlagen ist jedoch eine sehr starke Heterogenitat der Boden-N min -Gehalte innerhalb weniger Meter festzustellen. Zum ersten Beprobungszeitpunkt ist die Heterogenitat am geringsten und es wird mit 10 Einstichen ein cv von 10% erreicht, nach der Ernte sind dafur 18 Einstiche notwendig. Uberraschenderweise sind bei biologisch bewirtschafteten Schlagen im Mittel aller Probenahmetermine weniger Einstiche zum Erreichen einer angestrebten Genauigkeit (cv) notig. Ein cv von 25% bedeutet, bei 16 Einstichen liegt der Konfidenzbereich (p=0,05) bei 40 kgN/ha ± 6 kgN/ha oder bei 100 kgN/ha ± 14 kgN/ha. Fur einen cv von 10% ergibt sich bei 16 Einstichen ein Konfidenzbereich (p=0,05) bei 40 kgN/ha ± 2 kgN/ha oder bei 100 kgN/ha ± 5 kgN/ha.
Zu wenig Engagement im Hinblick auf die Nitratrichtlinie bescherte Deutschland eine Klage vom Europaischen Gerichtshof. Das war fur Praktiker und Wissenschaftler aus dem Knoblauchsland Grund genug, um uber den Gewasserschutz im Freilandgemusebau zu diskutieren.
