“…In addition to this, micronutrients such as Fe, Mn, Zn and Cu may also be unavailable (Kämpf, 2005). In a study performed by Chrysargyris et al (2019), while evaluating GM with mixtures of peat, perlite and paper waste, the authors observed that as pH increased (from 4.5 to 5.6), the availability of Ca, Fe, Zn and Cu also increased. raised.…”

“…needle for use as a substrate conditioner for the production of citrus seedlings. Ceccagno et al (2019) developed studies analyzing the mixture of this material with a commercial substrate and observed that it shows variation in EC values according to the granulometry used (3.5 and 8.0 mm for medium or coarse respectively), but always with low salt content, being less than 0.60 mS cm -1 (1:5, v/v method), when raw.…”

“…In low tech production systems, soil is also used, mainly due to its availability and easy acquisition, however it is not recommended because it negatively modifies the characteristics of a substrate and it is a potential inoculator of pathogens and invasive plants in the cultivation system (Avrella et al, 2021). There are also studies using regional materials such as pine needles (Ceccagno et al, 2019), residues of Brazil nut shell, acerola pit, assai pit and cupuassu peel (Araujo et al, 2020), babassu fiber (Nascimento et al, 2018) and coffee parchment biochar (Carnier, 2021).…”

Cultivation in protected environments and containers culminated in the need of the use substrates with specific chemical and physical characteristics; assuming that a fundamental role in cultivation of horticultural plants. In this way, the objective was to describe the main physical and chemical characteristics of substrates, as well as the main methodologies for analysis. As physical characteristics we can refer as examples: density on a wet and dry basis, total porosity, air space and water retention (easily available, buffering capacity and remaining water). The most important chemical characteristics in substrates include pH, electrical conductivity and available nutrient content. These characteristics are responsible for all the nutritional dynamics and the availability of water and air in the culture medium, so they must be known, tested and managed during cultivation. Thus, it is possible to establish parameters for plant cultivation in containers, being also possible to correlate its influence on plant development for scientific research.

“…Semelhantemente, o substrato casca de pinus, que é um subproduto do processamento de madeira de Pinus spp., é uma alternativa viável e disponível, sendo bastante utilizado para a produção de mudas, destacadamente de mudas de espécies florestais (MAEDA et al, 2007). Segundo Ceccagno et al, (2019), a casca de pinus compostada é um substrato química e fisicamente estável e por ser relativamente barato, é cada vez mais utilizado.…”

The objective of this work was to evaluate the potential of the processed coconut fiber (coconut powder) and composted pine bark, isolated and in combination, in promoting the growth of umbuzeiro seedlings. This work was conducted in a greenhouse in a completely randomized block experimental design, with five treatments and four replications. The treatments consisted of the following formulations, in volumetric proportions: 100% pine bark (CP); 75% CP + 25% coconut powder (PC); 50% CP + 50% CP; 25% CP + 75% CP and; 100% PC). The coconut powder substrates or the formulation containing 75% coconut powder + 25% composted pine bark provided Imbu seedlings with higher vegetative quality. The lower density, higher total porosity and higher percentage of available water were the physical characteristics of the substrates that most influenced the growth of Imbu seedlings.

“…Such composition will directly influence the seedling production process, thus, the chemical and physical properties need to be as favorable as possible for the growth and development of the species under cultivation (OLIVEIRA et al, 2014;TRAZZI et al, 2014;VIEIRA e WEBER, 2016). The growth of seedlings and the formation of the root system are directly related to the properties of the substrate, as well as their interaction with the container and water management (KÄMPF, 2005;CECCAGNO et al, 2019aCECCAGNO et al, e 2019b.…”

Butia lallemantii é uma palmeira de hábito cespitoso e caule subterrâneo, apresentando propagação assexuada. No entanto, faltam estudos relacionados às práticas de produção de mudas. O objetivo foi avaliar o crescimento e o desenvolvimento de plantas de Butia lallemantii submetidas a formulações de substratos e diâmetros de estipe. Mudas foram classificadas em duas classes de diâmetro de estipe (CDE) e dispostas nos seguintes substratos: comercial (CM); casca de arroz carbonizada (CAC); e CAC + pó de coco (CAC + PC - 1:1, v/v). Foram avaliados: número de perfilhos e de folhas pinadas (NFP), e ao final: comprimento, volume, massa fresca e seca de raízes e porcentagem de folhas vivas, durante 570 dias. Delineamento experimental foi inteiramente casualizado em esquema bifatorial (2x3), com quatro repetições. Não houve interação entre o substrato e os fatores de CDE para as variáveis do sistema foliar, entretanto, interação foi observada em todas as variáveis do sistema radicular. A classe 2 apresentou resultados superiores para NFP, e não houve substrato com variância significativa. No sistema radicular: a classe 2 e o substrato CAC permitiram resultados superiores. Portanto, os substratos CAC associados à classe 2 são adequados para o desenvolvimento de mudas de Butia lallemantii.
