Characterizing the physical and hydraulic properties of pine bark soilless substrates
Soilless substrates, such as peat, pine bark, and coir, are widely used as growing media in containerized crops for their favorable characteristics, including low bulk density, balanced air exchange and water retention, disease resistance, and low pH and salinity. However, improper irrigation of …

Soilless Substrate Hydrology and Subsequent Impacts on Plant-Water Relations of Containerized Crops
… order to continue to stay economically viable. Soilless substrates were initially developed to have increased porosity and relatively low water holding capacity to ensure container crops would not remain overhydrated after irrigations or rain events. As a result, substrates were selected that …

Hydroponic and Soilless Culture Systems and Transplant Practices Influence Production of Basil (Omicum basilicum L.)
… L.) grown in three different hydroponic and soilless substrate systems and (2) seedling tray cell-count and transplant date into hydroponic culture effects on basil growth and yield at harvest. For the first experiment, four basil cultivars (‘Genovese’, ‘Mrs. Burns Lemon’, ‘Sweet Thai’, and …

Soilless media for seed germination and growth of tomato transplants, and for the rooting of certain herbaceous stem cuttings
Media containing Weblite were compared to various media for its effectiveness in germination, plant growth and rooting. The 2M media were compared by determining the percentage germination and the dry weight after U2 days of Lycopersicon esculentum cv Better Boy, grown to transplant size. These …

Controlled and protected environment production of blueberries in the Midwest United States
… for containerized blueberry production via soilless substrates and/or with slow-release fertilizers in containers. The first project focused on propagating blueberries in soilless substrates. The second project evaluated plant performance and yield of these plants after they were …

The Role of Nitrogen Absorption and Utilization in Maintaining Lower Leaves of Chrysanthemum Morifolium, Ram. 'Cv. Mountain Peak' Under Low Light Conditions
… produced in winter had longer shelflife in soilless than soil mix medium, while no difference was found between either potting mix for summer production.

Optimizing Phytoremediation to Enhance Treatment Efficiency of Suspended Raingardens
… focused on the performance of lightweight soilless media, suitable for use in suspended raingardens, that support satisfactory growth of the plant’s root and shoot systems while also reducing the concentration of typical stormwater pollutants such as suspended solids, nutrients, heavy …

Water and nutrient transport dynamics during the irrigation of containerized nursery crops
… and dissolved nutrient (solute) movement through soilless substrates during irrigation. The following experiments evaluated fundamental water and solute transport principles through pine-bark based substrates. 1) Ilex crenata Thunb. 'Bennett's Compactum' were grown in 2.7 L containers. …

Quantifying the effects of fertilizer type, source, and concentration on the post-production growth of containerized culinary herbs
… into 11.4 cm-diameter containers filled with soilless substrate and irrigated with solutions varying in potential acidity (PA) or potential basicity (PB) and ratios of nitrogen to phosphorous (N:P) from commercially available water-soluble fertilizers . Plants were grown in 2 phases: 1) …

Plant Growth and Root Zone Management of Greenhouse Grown Succulents
… Liners were potted into a 60% bark/30% peat soilless potting mix. In group 1 , irrigation to container capacity occurred when volumetric soil moisture content fell below 30%, 20%, or 10%,. Group two (seven species) irrigation thresholds were shifted to 35%, 25%, and 15%. Effects of irrigation …

Ecology and horticultural potential of Dirca palustris
… North Dakota, and Maine to root-zone pH in soilless media, as the species has been reported both to favor alkaline or acidic soils. Although the provenances from which seeds were collected represented diverse soil pH, seedlings of D. palustris were nonetheless sensitive to root-zone pH and …

Switchgrass as an Energy Crop: Fertilization, Cultivar, and Cutting Management
… responses to N and P under well-defined, soilless conditions and to examine two N sources. Shoot biomass increased with N fertilization with an observed inflection point at 210 kg N ha-1. In these pot studies, root biomass increased with N only to 115 kg N ha-1. No significant effect of P …

Modeling risks associated with water reuse in agriculture
… of growing fish and plants together in a soilless system. Aquaponics has the potential to be a reliable source of healthy food for places lacking the land required for traditional agriculture, such as urban areas and islands. However, little research has been done on factors that determine …

Challenges in the Greenhouse Production of Rosmarinus officinalis L.
… rooted cuttings were potted in five different soilless media [Fafard 52 (24% peat, 60% bark, 8% perlite, 8% vermiculite); Fafard 3B (45% peat, 25% bark, 15% perlite, 15% vermiculite); Scott's Sierra Perennial Mix (25% peat, 65% bark, 10% perlite); Scott's Metro Mix 700 with Coir (25% coir, 50% …

Dissecting phenotypic inheritance of very-long-chain fatty acid inhibitor resistance in waterhemp (Amaranthus tuberculatus) using a novel greenhouse assay: 'PRIM'
Weedy plant species, especially within the genus Amaranthus, capable of surviving the selective phytotoxic effects of an EPA-approved chemical at its most vulnerable growth stage, represent a clear and present danger to the United States and perhaps the world. Such a threat, if left unchecked, may …

Influence of Lime and Micronutrient Amendments on Growth of Containerized Landscape Trees Grown in Pine Bark
Growing landscape trees in containers is a common practice in the nursery industry. In the southeastern United States, pine bark is often used as a container substrate, and two common amendments to pine bark are lime and micronutrients. In this study, three experiments were conducted to determine …

Nitrogen Fate and Transformations in the Production of Containerized Specialty Crops
Nitrogen (N) fertilizer is a required mineral nutrient in containerized crop production that is necessary for crop growth and development. Due to production aspects, the N added to crops far exceeds the amount that the plant uses and such inefficiency results in adverse environmental impacts …

Sulfur Requirements of Container-grown Pin Oak and Japanese Maple
The objectives for this research were to determine: 1) whether sulfated micronutrient addition increased growth of container-grown pin oak (Quercus palustris MuÌ nchh) and Japanese maple (Acer palmatum Thunb.) seedlings by supplying micronutrients, sulfur, or decreasing substrate pH, 2) S …
