“…Such evidence was supported by the enhanced growth and higher physiological parameters of seedlings grown in enriched substrates, as well as by the higher concentration of macronutrients in their needles. A number of studies confirmed that admixture of well-selected components to the peat can substantially improve physical properties of growth substrates and stimulate seedling growth (Heiskanen 1993, Bernier & Gonzalez 1995, Bakry et al 2013). In our experiment, a positive effect on nutrient uptake and biomass production of seedlings could be due to the admixture of several components to the enriched substrates, along with the peat type and the degree of humification.…”

“…Especially light low-humified Sphagnum peat has the required attributes (such as low pH, high cation exchange capacity, low inherent fertility, a proper balance of aeration and waterholding porosity) and provides reasonable growth conditions in the greenhouse (Landis et al 1990, Heiskanen 1993. Nevertheless, an admixture of proper components and fertilizers to pure peat can improve its physical (Heiskanen 1993(Heiskanen , 1995 and chemical properties (Juntunen & Rikala 2001, Fan et al 2004, and as a consequence, promote the growth and physiological quality of seedlings (Bernier & Gonzalez 1995, Bakry et al 2013. In Slovakia, peat is generally used as a growth substrate for production of container-grown seedlings.…”

“…In general, the substrates that were evaluated in the present study had percentages of moisture retention within the recommended values, which were increasing in the mixtures when increasing the percentage of sawdust, due to the size of the fine particles of that sawdust. As a consequence, aeration porosities were lower in the mixtures with higher percentage of sawdust, without presenting root rot problems due to excess moisture, since the size and composition of the pine bark particles provide a greater flow of air, and greater water filtration [29], although it is inevitable that the porosity decreases with time due to the compaction and settlement of the substrate by way of constant humidity changes [30].…”

Substrate is a factor that significantly influences the quality and production costs of nursery seedlings. The objective of this study was to evaluate combinations of peat moss, composted pine bark, and fresh pine sawdust in order to identify the proportions that favour the quality of Pinus engelmannii Carr. seedlings and minimise the production costs in the nursery. Substrates were formed using mixtures of peat moss (15% to 50%), composted pine bark (15% to 50%) and fresh pine sawdust (20% to 70%), with 2, 4 and 6 g L−1 of controlled release fertilizer (Multicote®, Haifa, Israel). A completely randomised experimental design with a factorial arrangement of 7 × 3 was used. The evaluated factors are root collar diameter, biomass, N-P-K content, and production costs of the substrates which were determined based on the container volume and three commercial quotations. Significant differences were found in root collar diameter and biomass, highlighting the treatments using 50% to 70% sawdust with 6 g L−1 of fertilizer. Assimilated values of N-P-K were acceptable in all treatments with 4 and 6 g L−1 of fertilizer. In the substrates with high percentages of sawdust, seedlings with morphological characteristics and nutritional levels within the values recommended for conifers were produced. In addition, it was possible to reduce the production cost of the substrates by up to 67%.

“…Due to its inherent qualities and multiple uses, the carob tree has been cultured and exploited for many millennia with records dating back 4000 BC. More recently, due to its high tolerance to drought, the carob tree has been used to restore marginal semi-arid and arid areas in numerous areas around the Mediterranean basin (Ozturk et al, 2010;Osorio et al, 2011, Bakry et al, 2013.…”

Factors determining forest species distribution include, in addition to external factors such as human interference and environmental management strategies, also soil and hydrological characteristics and climate conditions in any given areas. Modelling distribution has practical application in forest conservation and management, and help decision makers to develop strategies aimed at forest restoration, development of mountainous areas and the continuous and sustainable provision of forest-related services. Species distribution modelling (SDM) can be used for predicting species distribution based on tree presence records and on a number of environmental predictors. In this study we used MaxEnt for niche modelling in predicting carob (Ceratonia siliqua L.) trees spatial distribution in the Province of Azilal in Morocco. The results obtained show that a large area of the mountain regions is suitable for the expansion of Ceratonia siliqua stands. These findings will help decision makers in forest planning to better identify suitable sites for carob tree plantations and assess the potential of the exiting populations.
