“…Similar results of the macronutrients foliar contents also were obtained from swine manure (NADDAF et al, 2011). The use of sugarcane bagasse and filter cake also showed good availability of nutrients, and studies have corroborated the effective use of these components (FREITAS et al, 2008).…”

RESUMO Este estudo foi conduzido para averiguar o uso de substratos orgânicos na produção de mudas nativas do Cerrado brasileiro. O objetivo foi avaliar os parâmetros biométricos, nutrição e qualidade de mudas de guapeva (Pouteria gardneriana) produzidas em substratos contendo diferentes fontes de matéria orgânica. Utilizaram-se os seguintes componentes para a formulação dos substratos: subsolo (SB), casca de arroz (RH), composto de esterco bovino [CC (silagem de milho + esterco bovino)], esterco bovino (CM), bagaço de cana (CB), torta de filtro de cana (FC) e BioPlant (BP). Cinco substratos foram formulados utilizando proporções em base de volume, como segue: SB+RH (1:1, v/v), SB+CC (1:1, v/v), SB+CM (3:1, v/v), CB+FC (3:2, v/v) e BP. Avaliou-se o comprimento do caule, o diâmetro do colo radicular, o peso seco da raiz, o peso seco da parte aérea, a nutrição e o índice de qualidade Dickson. A utilização do CM como fonte de matéria orgânica proporcionou, em geral, os melhores resultados para as características biométricas e a produção de matéria seca. O uso de matéria orgânica nos substratos SB+CM (3:1, v/v) e SB+CC (1:1, v/v) melhorou a qualidade do solo e favoreceu o crescimento e qualidade das mudas de guapeva, e podem ser indicados como substratos alternativos.

“…The measurement of the water retention curve of horticultural substrates is generally executed with the sand box and the pressure plate extractor [1,8,9]. These methods and devices are outdated, the measurement is time-consuming, the equipment is expensive, and the results are affected by uncertainties [10].…”

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 used methods and devices for quantifying the water retention properties of horticultural substrates (sand box, pressure plate extractor) are outdated. The measurements are time-consuming, the devices are expensive, and the results are affected by uncertainties. Here, the suitability of the extended evaporation method (EEM) and an associated HYPROP (HYdraulic PROPerty analyser, device was successfully tested for very loosely-bedded horticultural substrates. EEM and HYPROP enabled the simultaneous and effective measurement of the water retention curve and the unsaturated hydraulic functions. The measurement time of horticultural substrates ranges between 7 and 10 days. Furthermore, the shrinkage properties and the water rewetting time can be measured with the HYPROP system. Results using 18 horticultural substrates are presented. These results are discussed and compared with natural organic and mineral soils showing the specific hydraulic performance of substrates for horticultural applications.

“…High water saturation levels reduce the supply of oxygen from the air to the roots, often reducing root growth and function and thus affecting water uptake by roots (Spomer 1990). Mean water content in containers tends to decrease with increasing container height for the same volume of growing media (Gizas and Savvas 2007;Al Naddaf et al 2011).…”

“…Most of the studies dealing with container size and geometry address issues related to the nursery industry. Only a few studies (Campbell et al 1985;Gizas and Savvas 2007;Al Naddaf et al 2011) have dealt with the actual effect of container geometry on the yield and quality of vegetables grown in containerized production systems.…”

significantly with container height, especially for the high irrigation frequency treatments. Container geometry had an effect on the water and temperature regimes. Water content values in tall and narrow containers were lower than those in short and wide containers that had an equal volume of growth medium per unit length. Higher medium temperatures and daily fluctuations were observed in the tall containers. The calculated evapotranspiration rate was higher in the tall containers, and a stronger effect on evapotranspiration was obtained with high irrigation frequency.
