Floating treatment wetlands (FTWs) are a plant-based technology shown to remove excess nutrients and metals from surface waters under variety of conditions. Plants established in FTWs can accumulate store within their tissues, but the amount uptake storage is dependent on plant species nutrient influent concentration. This research was designed quantify influence load two partitioning patterns tissues (shoots roots) so that management recommendations for be developed better protect water...
Improvements in sensor technology coupled with advances knowledge about plant physiology have made it feasible to use real-time substrate volumetric water content sensors accurately determine irrigation timing and application rates soilless substrates greenhouse container production environments. Sensor-based uses up-front investments equipment system calibration return for subsequent reductions associated costs of energy labor, spending on fertilizer, disease losses. It can also accelerate...
Water scarcity is likely to increase in the coming years, making improvements irrigation efficiency increasingly important. An emerging technology that promises substantially a wireless sensor network uploads data into management software, creating an integrated system allows real-time monitoring and control of moisture status has been shown experimental settings reduce costs, lower plant loss rates, shorten production times, decrease pesticide application, yield, quality, profit. We use...
We describe and estimate the potential environmental benefits associated with adoption of wireless sensor irrigation networks (WSIN) in United States ornamental crop production. Benefit estimates are based on results from on-farm research conducted during previous three years, using both conservative optimistic assumptions about levels WSIN technology adoption. project reductions water use air emissions for six U.S. agricultural regions, overall, states that make up Chesapeake Bay watershed....
Irrigation return water from container plant nurseries often contains elevated levels of nitrogen (N) and phosphorus (P). Floating treatment wetlands (FTWs) are one solution for removing nutrients irrigation flow. This study assessed how FTW planting strategy (monoculture vs mixed planting) influenced removal N P. Tanks containing FTWs received with ∼22.3 3.12 mg·L-1 P water-soluble fertilizer every 7 days two, 8-week experiments. Experimental treatments were a control (open water);...
Restoration efforts in the Chesapeake Bay recently intensified with 2010 introduction of federal total maximum daily load (TMDL) limits for all 92 bay watershed segments. These regulations have specific, binding consequences if any six states or District Columbia fail to meet interim goals, including loss dollars various programs and increasing regulation point sources, non-point source (agricultural urban) nutrient reduction goals are not met watershed. As part effort better understand...
Nursery, floriculture, and propagation production accounted for 79% ($13.3 Billion) of 2017 ornamental specialty crop in the United States. Access to high quality water sources is increasingly limited irrigating these economically significant crops. Given production, environmental, economic issues associated with use water—including recycled, reclaimed, surface, ground water—it critical develop sustainable runoff, containment, remediation technologies, identify alternative water. To better...
Irrigation management systems that use wireless transmission of substrate moisture data are beginning to become commercially available for ornamental growers, particularly in soilless substrates. These allow growers precisely monitor and control irrigation real time being shown save other resources. On-farm evaluations indicate these have potential benefits extending beyond reductions water associated inputs: Some growing experience increases plant growth rates, with corresponding production...
Quantifying the range of fertilizer and irrigation application rates applied by ornamental nursery greenhouse industry is challenging as a result variety species, production systems, cultural management techniques that are used. To gain better understanding nutrient water use in Maryland, 491 potential operations (including multiple addresses contacts) state were mailed packet information asking for their voluntary participation. Of operations, it was determined 348 currently operation....
This experiment measured plant growth of a halophyte (species adapted to saline conditions) confetti tree ( M aytenus senegalensis ) using runoff from kneeholy plants R uscus aculeatus ). Three irrigation treatments were used, standard nutrient solution or control (T 0 ), water collected irrigated with the blended 50:50 tap 1 and 100% 2 in which concentrations analy z ed by high-performance liquid chromatography. Growth, photosynthetic parameters, mineral composition at end experiment....
Diagnosis and Recommendation Integrated System (DRIS) norms for nitrogen (N), phosphorus (P), potassium (K), sulfur (S), chlorine (Cl) sodium (Na) nutrient sufficiency ranges Aloe vera, Kalanchoe blossfeldiana, Lavandula multifidi, Rosmarinus officinalis were based on two experiments. DRIS ratios computed selected. Nutrient developed using the data of whole population according to approach. The development revealed that only K. blossfeldiana R. showed limiting nutrients. each species...
