Hydraulic Performance of Horticultural Substrates—1. Method for Measuring the Hydraulic Quality Indicators
Besides nutrient composition, the hydraulic performance of horticultural substrates is a main issue for evaluating their quality for horticultural purposes. Their water and air capacity and their suitability for transporting water are important hydraulic quality indicators. Shrinkage and water repellency could have a negative impact on storing and transporting water and solutes. The commonly us...
متن کاملProblems & Considerations in Determining Physical Properties of Horticultural Substrates
The establishment of research protocol for horticultural substrates must include the measurements of physical and hydraulic properties. Both empirical and mechanistic approaches must be utilized in protocol development. The steps in establishing a protocol should be: 1) the development of standard definitions for properties and terms, 2) development of a mechanistic framework based on modeling,...
متن کاملHydraulic Performance of Horticultural Substrates—3. Impact of Substrate Composition and Ingredients
Abstract: Horticultural substrates, also referred to as growing media, potting soils and gardening or soilless substrates, are widely used as a basis for vegetable and flower production in horticulture. They are created as a composition of different ingredients (bog peat, organic residuals, coir, perlite and other components). Hydraulic properties such as water storage capacity, air capacity, s...
متن کاملHydraulic Performance of Horticultural Substrates—2. Development of an Evaluation Framework
Sustainable, environmentally friendly and resource-saving water and nutrient management in horticulture requires knowledge of the hydraulic suitability of horticultural substrates for each specific application. The aim of this study was to develop methods and a rating framework to assess the hydraulic performance of horticultural substrates. The hydraulic criteria related to high-quality hortic...
متن کاملPolyacrylamide Hydrogel Properties for Horticultural Applications
Polyacrylamide (PAAm) hydrogels are commonly employed to ensure soil hydration in horticulture, but studies have shown that they have a minimal effect on crop life and quality. The reasons for this poor performance are not understood since the commercial hydrogels have not been adequately characterized. PAAm hydrogels were synthesized and their properties were measured along with those of comme...
