Abstract Shoot and root growth of plants grown in substrate blends containing cotton gin compost (CGC) were compared to plants grown in a traditional pine bark (PB) blend. In 2002 ‘Winter Gem’ boxwood, ‘Firepower’ dwarf nandina, and ‘Midnight Flare’ azalea were potted in four substrate blends containing by volume 6:1 PB:sand (S), 4.5:1.5:1 PB:CGC:S, 1:1 PB:CGC, or 1.5:4.5:1 PB:CGC:S. Plants were grown for nine months on a container pad in Auburn, AL. In 2003–2004 this study was repeated with ‘Renee Mitchell’ azalea as a replacement for ‘Midnight Flare’ azalea. Periodic growth measurements and a final visual root ball evaluation were conducted in each experiment. Substrates were analyzed to determine physical properties (air space, water holding capacity, total porosity, and bulk density) and chemical properties (pH and electrical conductivity). In both experiments, growth indices of all cultivars in substrates containing CGC were similar to or greater than those of the PB:S control blend. Visual quality of root systems was similar for all plants across all substrates.

Abstract The objective of this study was to determine the effect of arcillite, a calcined montmorillonite and illite clay, on the physical and chemical properties of a pine bark growth substrate and plant growth. To accomplish this, Cotoneaster dammeri ‘Skogholm’ and Rhododendron sp. ‘Sunglow’ were potted into pine bark substrate amended with 0, 27, 54, 67 or 81 kg/m3 (0, 45, 90, 112 or 136 lbs/yd3) arcillite. Plants were irrigated every l, 2, or 4 days. Container capacity, available water, and bulk density increased with increasing arcillite rate. Air space decreased with increasing arcillite rate. Total porosity and unavailable water were not affected by arcillite. Substrate NH4, NO3, P, K, Ca, and Mg concentrations increased with decreasing irrigation frequency. Substrate NH4, P, and K concentrations increased with increasing arcillite rate suggesting that arcillite improved retention within the container substrate. Azalea ‘Sunglow’ shoot dry weight decreased linearly with decreasing irrigation frequency and increased curvilinearly with increasing arcillite with maximum dry weight occurring at 67 kg/m3 (l12 lbs/yd2). Cotoneaster ‘Skogholm’ shoot dry weight increased linearly with increasing arcillite rate at 2 and 4 day irrigations and curvilinearly at 1 day irrigation with maximum weight at 67 kg/m3 (112 lbs/yd2).

Quality cassava(Manihotesculentus, Crantz) flour is often influenced by process variables such as slice weight and soaking time which may affect its nutritional quality. In this study, the effect of process variables (slice weight and soaking time) on quality of cassava flour was carried out. Cassava root was peeled, washed and cut into varied sizes (25.86 - 54.14 g) and soaked at varied time (7.03 - 40.97 h). The proximate composition, physical and chemical properties of the flour were carried out using standard methods. The result in our findings showed that slice weight and soaking time had significant increase (p<0.05) on the proximate and physico-chemical properties of the flour.The amylose and amylopectin content of the flour increased with increasing soaking time while the hydrogen cyanide content decreased with increase in soaking time. Overall, the quality cassava flour displayed desirable properties for its incorporation into baked goods.

Efficient nursery production of woody plants, as well as the level of their successful application in urban green spaces, greatly depends upon properties of substrates in which these individuals grow, develop and endure. Furthermore, quality of substrate does not only affect the quality of future product (plant individual or green space), but distinctly determines its price. This element, extremely significant for all countries in transition, thus Serbia as well, commands finding ways of making qualitative, but least expensive substrate. The most logical solution is to use mixtures/substrates of precisely defined properties, composed of domestic components. Results presented in this paper imply that it is possible to create precisely such standard mixtures from domestic resources at relatively low cost, adjusted to needs of particular species, which would ultimately lead to successful, non-expensive nursery production and application of produced stock, both on domestic and foreign markets.

The physical and chemical properties such as particle size, montmorillonite content, swelling degree, water absorption, and blue absorption of A, B, and C bentonites were studied under laboratory conditions. The effects of adding different quality and different proportion of bentonite on falling strength, compression strength, and shock temperature of green pellet were investigated. The experimental results show that the montmorillonite content, water absorption, and methylene blue absorption of bentonite-B are the highest. And the quality of bentonite-B is the best, followed by bentonite-C and bentonite-A poor quality. When the amount of bentonite-B reduced from 1.5% to 1.0%, the strength of green pellets and the shock temperature both decrease. As the same proportion of A, B, and C bentonites, the green-ball strength and shock temperature are as follows: bentonite-A > bentonite-B > bentonite-C.

O objetivo do presente trabalho foi avaliar a viabilidade técnica da utilização de diferentes substratos para a produção de mudas de Sebastiania commersoniana e relacionar suas características físicas e químicas com a qualidade das mudas produzidas. Para tanto, foram formulados 22 substratos, os quais tiveram suas propriedades físicas e químicas avaliadas, sendo a semeadura realizada em tubetes de 120 cm³, acondicionados em casa de sombra, com irrigação controlada. Para a análise dos resultados, foram feitas avaliações de altura, diâmetro de colo, biomassa seca aérea e radicial, facilidade de retirada do tubete, agregação das raízes ao substrato, índice de qualidade de Dickson e relação altura e diâmetro de colo aos 180 dias. De acordo com os resultados obtidos, conclui-se que o melhor substrato testado foi o substrato comercial à base de casca de pinus. Os componentes renováveis, casca de arroz carbonizada, fibra de coco e substrato comercial à base de casca de pinus, apresentaram-se viáveis tecnicamente para produção de mudas de branquilho, enquanto que a casca de arroz carbonizada pura e vermiculita fina não apresentaram viabilidade. No que se refere às propriedades dos substratos, apenas a densidade aparente, pH, Ca e P apresentaram correlação com as variáveis biométricas das mudas. AbstractEffects of different substrates in production of Sebastiania commersoniana seedling. The aim of this research was to evaluate technical feasibility of using different substrates for production of seedlings of Sebastiania commersoniana and relate physical and chemical characteristics to the quality of the produced seedlings. In order to that, 22 substrates were formulated, with their physical and chemical properties evaluated, sowed in tubes of 120 cc, and put in shade, under controlled irrigation.

Cagaita originates from the Brazilian Cerrado and belongs to the Myrtaceae family. It is a fruit tree and widely disseminated in the Brazilian Cerrado, and can reach up to 10 meters high. To obtain quality seedlings it is necessary to use substrates that have physical and chemical properties suitable for plant development. Also, the quality of the substrate is directly related to the proportions and the material that makes up the mixture. The experiment was conducted in a greenhouse at the Federal Institute of Education (IFTO), Science and Technology of Tocantins, Gurupi/TO city, from November 1, 2017, to February 26, 2018. Cagaita (Eugenia dysenterica DC.) seeds taken directly from the fruit were used to perform the experiment, which was collected in the urban region of Peixe - To in October 2017. Six types of substrates were used for the installation of the experiment, which was: Washed Sand; Washed Sand + Coconut Shell + Black Soil + Poultry Manure; Black Soil; Pine Bark + Poultry Manure + 25% Commercial Substrate Plantmax®; Earthworm Humus + Black Soil + 25% Commercial Substrate Plantmax®; 25% Commercial Substrate Plantmax® + Poultry Manure + Black soil + washed sand. The substrates of earthworm humus + Black Soil + 25% commercial substrate Plantmax® and 25% Commercial Substrate Plantmax® + Poultry Manure + Black Soil + Washed Sand provided the highest values of viability and vigor in Cagaita seeds.

Anthropogenic lakes constitute one of the most significant genetic groups of lakes in Czechia. The water quality of these lakes formed through flooding of mined-out pits can be influenced by a number of factors such as physical and chemical properties of exploited rock, characteristics of the mine surroundings, secondary anthropogenic interference and time elapsed since their flooding. The quality of water determines their potential utilization, such as in water supply, agriculture, industry, recreation, nature preservation, etc. This article compares five anthropogenic lakes in mining pits after exploitation of different kind of rocks and on the basis of lake basin characteristics and physical and chemical analysis of water formulates the possibilities of their potential utilization in the context of the local landscape.
