Modern research greenhouse with a glass surface of 3,000 m² for experiments in the field of plant nutrition, phytopathology and plant growth.

The fully automatic, computer-operated facility is a compound construction consisting of 77 autonomous compartments, each of which represents an independent unit in terms of climate management, irrigation, fertilisers and light, if required.

All parameters can be visualised, recorded and illustrated graphically via the supervisory computer system.

The outside walls are clad with Thermoplus insulation glass and the ceiling with float glass. The temperature is regulated via convector and under-bench heating, ceiling and wall ventilation systems, as well as a combined shade/heat screen; two compartments are equipped with condensation coolers.
Air humidity is regulated via a high-pressure fog system, which can also be used for cooling at temperatures of above 27° C.

Additional lights can be controlled via two circuits for each compartment, either in an assimilative or photoperiodic manner, parallel with different lamp types (sodium vapour, metal halide) and provide a quantum density of 400 µEinstein.

The automated irrigation and fertiliser system uses service water and partially desalinated water with approx. 10 µs. The water supply is provided via an ebb and flow system, drip irrigation or via Bato sprinklers.

There is one chamber equipped for the use of isotopes and one soil house, in addition to the chambers and compartments.

Six fully climatized vector-secure chambers are equipped with thermal waste water disinfection. HEPA filters keep the air flowing into and from the chamber sterile.

An 8 x 34 m greenhouse with folding roof that can be used for infection experiments, for example, and a cold frame facility to cultivate and hibernate young plants.

Description:
Two chambers in which temperature, air humidity, illumination level and CO2 levels are  computer-regulated to fully simulate environmental conditions.
Phytotrons can be used to simulate various different environmental conditions. Thus, the current climate could be compared to a climate scenario that features increased temperatures, higher CO2 levels and water stress.
The facility consists of two separate phytocells, with a floor space of about 7 m² and a clear height of 2.07 m each.

CO2 regulation:
The CO2 levels can be increased or decreased using a CO2 dosing apparatus to simulate specific environmental conditions. Plant CO2 absorption can be measured via an analytical device.

Illumination:
Growth illumination: assimilation-effective light from sodium-vapour and metal-halide lamps, as well as fluorescent tubes about 50 cm from the light level. Lamp casing made of UV-retardant, but UV-permeable materials.
Light controls with four levels up to a maximum of 30,000 lux with 12 lamps 250 W NaH / 12 lamps 250 W HQ.

Air humidity:
30 - 90 % rF (tolerance: 5 % rF absolute)

Air temperature:
+ 5°C to + 30° C seasonal and spatial (tolerance: 1°C )

Air speed:
max. 0.2 m/sec at the vent opening

Airflow:
Through the floor, vertically; fresh air flow can be controlled or switched off (65 m³/h)

Lysimeter

Lysimeter

Lysimeter tests allow for the continuous recording of data for basic parameters in the water supply and nutrient and pollutant dynamics of soils. The dynamics of nutrients in lysimeters provide an acceptable, approximate simulation of free-range conditions.

The nutrient cycle of agricultural ecosystems is more or less influenced by actions, such as organic (commercial fertilizer, sewage sludge) and mineral fertilisation, use of pesticides, intensity and type of soil preparation, crop rotation, sprinkling, atmospheric depositions etc.

Knowledge about causes of pollution, pollution vectors and effect mechanisms is of particular importance to find strategies to regenerate polluted and maintain intact agricultural ecosystems.

Location:

The lysimeter facility is located from a climate perspective in a transition area between the Western European Climate Zone (mild winter, humid, cool summers) and the Eastern European Climate Zone (cold winters; hot summers). However, the location is considered part of the Pannonian region from a vegetational-ecological perspective. An annual temperature average of around 9.5°C and annual average of precipitation of 550-600 mm are typical for this region. The facility is 160 m above sea level.

Both the location of the lysimeter facility and the locations where the soil samples are taken in Fuchsenbigl and Orth an der Donau are part of the main production region Northeastern lowland and hillside and the minor production region Marchfeld. The Marchfeld is an area used intensively for agriculture. It is also known as “Austria’s breadbasket”. Irrigation is used in this region to bridge occasional drought periods. The main crops in the Marchfeld region are cereals (quality wheat), sugarbeet, field vegetables and potatoes.

Intensive agricultural use and artificial irrigation causes a major problem as important nutrients are washed into the groundwater.

Equipment:

A total of 18 round steel containers with three different types of soil from the Marchfeld region equipped with probes to measure groundwater pollution caused by agricultural activities (fertilisers, crop rotation, pesticides, etc.)

Each lysimeter container is equipped with:

  • Tipping gauge incl. collector for seepage water: the tipping gauge is equipped with a double seesaw and a tip volume of 4 ml, recording the amount of seepage water at varying time intervals.
  • Tensiometer with temperature sensors at distances of 30 cm, reaching down to 210 cm into the soil: the tensiometer is over the top of a ceramic tube in contact with the groundwater so that the pressure of the groundwater is transferred to the pressure sensor of the device. This helps to find out about the soil’s water balance depending on the soil type and the distribution of pores. Combined with a temperature sensor, the tensiometer also records the impact of soil temperature on the nutrient cycle. 
  • TDR probes at distances of 30 cm, reaching down to 180 cm into the soil: the TDR method (Time Domain Reflectometry) makes it possible to determine the water levels in the soil by measuring the reflections of electromagnetic waves transmitted by the probe. It records the volumetric water level in the soil and is able to trace seepage water  depths.
  • Suction tubes at distances of 30 cm, reaching down to 210 cm into the soil: a membrane vacuum pump is used in combination with a pressure regulator to create suction tension to suck groundwater into the collection containers. It is possible to take groundwater samples from different soil depths individually and analyse the combination of nutrients in the groundwater of the individual soil layers. 

Weather station:

Air temperature 2 m above the ground; air temperature 5 cm above the ground; relative air humidity 2 m above the ground; air pressure; wind speed 10 m above the soil; precipitation gauging 1 m above the ground; precipitation gauging at ground level; soil temperatures 10 cm, 30 cm, 60 cm and 90 cm below the ground.

Data recording:

Each lysimeter and weather station has its own data logger to record the data. A data average is created and recorded every 10 minutes.

Container Test Station

Container Test Station

Greenhouse with Kick Brauckmann Containers to test:

  • Positive and negative effects of agricultural Inputs 
  • Drought and water stress 
  • Over and undersupply of nutrients 
  • Test of active substances

Technology:

The container test station provides the opportunity to carry out scientific experiments in plant containers under controlled outdoor conditions. More than 1,000 containers can be set up in an area of almost 500 square meters.

The area is equipped with 66 mobile tables built in a way that each can carry 16 Kick Brauckmann pots (specially designed plastic containers; height: 26 cm, diameter: 30 m, volume: 8 l ).

The roof and walls of the greenhouse are made of glass. Both the retractable roof and walls are usually kept open, but will be closed automatically by the greenhouse control computer system during rain, strong wind and extreme temperatures. The entire test station is covered with a plastic bird net for protection.
