Evaluating Substrate Stratification Practices For Enhanced Water Resource Management In Nursery Production, Kristopher S. Criscione
Evaluating Substrate Stratification Practices For Enhanced Water Resource Management In Nursery Production, Kristopher S. Criscione
LSU Master's Theses
The nursery and greenhouse industries have continued to increase in production and sales over the past two decades. This increase in horticultural production necessitates a greater demand for finite natural resources, specifically water. Sustainable water resource management will be critical to the success and continual growth of the nursery industry. Strategic irrigation scheduling and innovative substrate management practices can improve nursery resource efficiency. Soilless substrates were originally utilized by the industry to increase substrate air-filled porosity, to ensure adequately drained container systems. Thus, the implementation of these soilless substrates can lead to an inefficient use of water and fertilizer. Substrate …
Influence Of Fertilizer Source And Irrigation Regimen On Containerized Production Of Coleus (Plectranthus Scutellarioides (L.) Codd) 'Solar Sunrise' And Management Of Bermudagrass (Cynodon Dactylon (L.) Pers. X C. Transvaalensis Burtt-Davy) 'Tifway', Kayla Renee Sanders
LSU Master's Theses
Fertilizer nutrient losses through leachate and runoff from excessive irrigation in nursery container production and turfgrass management can be high and have negative environmental impacts. The objective of this research was to examine the influence of fertilizer source and irrigation regimen on nutrient losses during nursery container production and turfgrass management. During the container production of coleus (Plectranthus scutellarioides (L.) Codd) 'Solar Sunrise', four fertilizer treatments: an unfertilized control; a controlled-release (CRF); a water-soluble (WSF); and a combination of 10% WSF and 90% CRF, were incorporated into a pine bark substrate at 0.30 kg N and P·m-3 in 3.7-L containers …
