Precision irrigation in nursery using wireless tensiometers

To ensure better management of water resources and reduce the impact on the environment, it is essential to move toward precision irrigation. A new generation of wireless tensiometer that measures the water available to the plant and allows precise irrigation control has been evaluated.  For improved efficiency, the best clustering practices based on the water needs of diverse species have been established.   Evaluation of the best irrigation strategies in a commercial setting have demonstrated that water use can be reduced while maintaining an optimal growth. Recommendations have been made for improved water management practices in plant nurseries with the potential to help growers across the country.

Impact of turfgrass fertilization on nutrient losses through runoff and leaching

“This research project evaluates the use of different types of turfgrass fertilizers and their impacts on nutrient runoff and leaching. The project compares nutrient losses from turfgrass fertilized with natural, synthetic and compost fertilizer sources to unfertilized turfgrass, as well as measuring the impact of cultural practices like aeration, clipping recycling, and overseeding.
The project compared the effect of five different maintenance programs, based on real-life situations, on: turfgrass quality, nutrient losses through runoff and leaching, soil moisture and temperature, and soil fertility level.”

Evaluation of turf fertilization run-off impact and mitigation techniques

A comparison of the effect of four different maintenance programs on turfgrass quality, nutrient losses through runoff and leaching, and soil fertility level. Twelve plots evaluated five different maintenance regimes that included aerification, topdressing, weed control and fertilization. Results suggest that fertilized turf uses less water than unfertilized turf.

Winter greenhouse heat consumption reduction

Researchers have found that significant energy reductions of up to 20% can be achieved by a combination of reduced night time temperature, morning CO2 injections and ventilation control. The specific combination of these climatic adjustments enables average temperatures to be maintained at the optimal level and produces more vigorous plants that are ready for holiday delivery dates
