NE-164: Decision/Support for Design and Control of Plant Growth Systems
Summary of Project 2001
Objective 1: Integrate environmentally acceptable and economically-profitable management models into crop growth control and profitability
1 a. Develop decision/support tools based on plant growth and development models to enhance crop growth control and profitability
Two closed, contrasting, watering systems are being studied and contrasted: an ebb and flood floor system at Rutgers University and a deep trough hydroponic system at Cornell University.
The Rutgers irrigation system was installed in an open/roof greenhouse in preparation for operation of the greenhouse during the coming year. The system is closed, with make-up water added as needed and nutrients then added as needed by fertilizer injectors. The system will be operated during the coming year and its characteristics quantified. Monitoring the fertilizer addition rates can, ultimately, be used to develop nutrient uptake models that can lead to more effective addition of fertilizer at lower cost.
The Cornell system was developed and is being operated to confirm and expand (or tune) models of plant growth and transpiration using lettuce in deep troughs. Additionally, a neural network model is being completed that is proposed to be the first step of a fault detection procedure that can be implemented to detect anomalous behavior of the components of plant production systems by monitoring and predicting transpiration, EC and pH, and comparing predictions to measured values. Such a fault detection method can identify problems in their initial stages (typically within 20 minutes) , when time will still permit remedial actions to limit crop damage and production loss.
Ohio State University (through OARDC, the Wooster campus) has developed a decision support program for hydroponic tomato production. The decision support algorithm is based on thirteen growth functions and is available as an interactive computer program through the OARDC web site. The site is actively used by commercial hydroponic tomato growers.
Two doctoral theses at Rutgers University have provided computer models to advance the development of management models for plant production systems.
One doctoral thesis developed a computerized algorithm to simulate and
compensate for effects of environmental perturbations on production and
scheduling of hydroponically grown wheat, soybean and white potato in
controlled environments.
A second doctoral thesis provides mathematical computer modeling tools
capable of implementation for system level analysis. The focus was
application to advanced life support systems such as the International Space
Station, but the approach was object oriented and the computer model provides modules that could be applied to commercial plant production as well.
Precision microirrigation studies continue at Ohio State University. Measured and modeled evapotranspiration comparisons are being accumulated with the goal of modeling ET as a method to control irrigation of nursery plants individually and avoid excessive irrigation and nutrient loss to the environment.
Ohio State University continues to develop IPM tools to reduce pest pressure and pesticide use through greenhouse environmental control. A series of fact sheets has been published.
lb. Develop an integrated information data base on CEA plant growth systems to facilitate analysis and produce a decision-support tool.
Two stations are exploring plant lighting topics, one aspect is light integral control and the other is spectral quality of supplemental light.
Cornell University continues to develop and test a total daily PAR integral
control method and is testing it in a prototype commercial lettuce production
greenhouse. Control appears to be generally within one mol/m2 of daily PAR
integral, or within 8%, with most days much better than this.
Michigan State University is exploring the effects of spectral quality on plant
growth and morphology. A wide variety of crops is being tested.
Each aspect is important for developing decision support tools related to plant lighting for the control total growth and plant quality, and timing of development.
Cornell University conducted an industry survey and several focus group discussions to review industry experiences, assess major management concerns with adopting sub irrigation systems, and establish benchmarks to estimate cost in capital investment analyses related to four alternative zero runoff systems (ebb and flow benches, Dutch movable trays, flooded floors, and trough benches). The survey showed growers adopt zero-runoff technologies to improve product quality and production efficiency, not to prepare for impending environmental regulations.
Objective 2: Enhance commercial greenhouse design, water management, and environmental systems for cool and cloudy climates
2a. Develop design and control recommendations for naturally ventilated greenhouses
An open-roof greenhouse at Rutgers University is being modified with new sidewall panels and two motorized side vents to allow for ventilation during times of high winds and rainy weather. Construction of the greenhouse continues with floor heat and a gasfired boiler system to be installed. Open roof greenhouses are increasingly popular with commercial growers, and the Rutgers system will provide a working system to develop design and operating guidelines suitable to cool, rainy climates, but with hot summers, such as characterize the Northeast.
Researchers at Ohio State University continue to develop methods to quantify air flow rates and patterns in naturally-ventilated greenhouses using the computational fluid dynamics computer model, FLUENT. More effective placements of side and roof vents have been identified, with the resulting natural (wind-induced) ventilation rates being comparable or better than the rates provided by fan ventilation systems. Interactions between researchers at Ohio State and Cornell continue related to systematic evaluations of FLUENT results as derived from modeling wind ventilation of greenhouses.
Use of insect screens is not practical with naturally-ventilated greenhouses. Moreover, the typical negative pressure system used for fan-ventilated greenhouses draws insects through every inadvertent opening, providing short-circuit paths for air around screens. Rutgers University is completing a study of a positive-pressure system that can be an alternative to other ventilation systems, both mechanical and natural.
2b. Enhance technology transfer and research in supplemental lighting
See section lb above for related supplemental lighting research.
Michigan State University continues to explore environmental conditions and plant responses under near-infra red reflecting greenhouse films used as shade curtains. Recently available films show a good ability to reflect near IR to save energy, with minimal PAR (Photosynthetically Active Radiation) reduction.
A collaborative project between Rutgers University and the University of New Hampshire, with a commercial collaborator in New Jersey, was initiated to study and quantify the economic feasibility of supplemental lighting for commercial plug production. The study continues.
2c. Improve greenhouse wastewater treatment through use of constructed wetlands or phytoremediation
No activities to report during the current year of effort.

It should be noted that three new fact sheets were developed as a collaborative effort between Rutgers University and The Pennsylvania State University.
