“…BC and other carbonized materials have also been proposed as peat alternatives due to their capacity to mimic peat properties such as high porosity, structural stability, low bulk density, and high-water retention capacity [5,17]. Nevertheless, these carbon-rich materials do not provide nutrients to the mixture [18] and, therefore, require the addition of fertilizers and compost to sustain plant growth [19].…”

Peat is the predominant component of growing media in soilless horticultural systems. However, peat extraction from peatlands destroys these fragile ecosystems and emits greenhouse gas emissions (GHG). Peat replacement by other growing media is, thus, paramount to ensure a more sustainable horticultural sector. This study investigated the agronomical performances of two spent coffee ground-based composts with and without biochar, during three different stages of tomato (Solanum lycopersicum L.) development: seeds germination (0–6 days), seedling development (7–49 days), and plant-to-fruit maturity (36–100 days). The two composts were used as peat replacement and mixed with peat at four different volumetric proportions: 100% (pure compost), 50%, 30%, and 15%. The substrates had a stimulant effect on seed germination but induced stunted growth due to the elevated electrical conductivity. For the latest stages of plant development, compost with and without biochar mixed with peat at 50% promoted an increase in fruit production of 60.8% and 100.3%, compared to the control substrate. The present study provides evidence that combining biochar with spent coffee ground compost represents a potential alternative for peat-based growing media promoting a circular production model in the horticultural sector, but the results are dilution- and plant development stage-dependent.

“…According to Bezerra et al (2017) and Tacon (1989), shrimp head silage is a good source of several mineral nutrients, both for fertilization in plants and the manufacture of feed and food. Nocentini et al (2021) stated that chitin residues generated from shrimp parts can be recycled for use in soils lacking in nutrients such as N and P.…”

Appropriate waste handling is a concern in the fishing industry, seeking to minimize harm to the environment. This study aimed to evaluate vegetative growth at different concentrations of solid residue from shrimp farming in tomato seedlings. Tomato seeds cv. Santa Clara were sown in trays with substrate, until uniform germination and further development for transplant. The concentrations of the shrimp residue were mixed with coconut powder for use in the following treatments: coconut powder (control), 5, 10, 15 and 20 g of shrimp residue, with 8 replicates per treatment. After 7, 14, 21 and 28 days after transplant, the number of leaves and the length of the aerial part were evaluated. At the 50th day, the remaining phytotechnical, physiological and X-ray microanalysis characteristics were evaluated. The three parts of the solid residues were rich in macro and micronutrientes (Fe > Zn > Ca > S > P > Mn > Na > Mg > K > N). The plants grown with different concentrations of shrimp residue had a significant difference for the photosynthetic rate and transpiratory rate, starting at 10 g kg-1. The use of the P3 shrimp residue (cephalothorax + abdomen) was promising and could replace the use of fertilizers in the development of plants, reducing the amount of material released to the environment and easing degradation. The concentration of 10 g kg-1 of shrimp residue was efficient for the morphophysiological development of the tomato plants cv. Santa Clara.

“…Recently, some organic and inorganic wastes have been proposed as substitutes to peat [24,25]. For example, numerous studies have investigated the use of biochar as a plant growing substrate [26][27][28][29]. However, production costs for biochar and other components must be systematically assessed and compared with peat, as recommended by Haeldermans et al [30], who evaluated the techno-economic viability of biochar production.…”

Plant growing substrates obtained by composting agro-industrial waste can serve as organic soil amendments. However, it is crucial to determine the maturity and quality of organic amendments before their application to soil. This study aimed to evaluate the suitability of compost obtained from poultry wastes combined with five different vegetal residues (tree trimmings, sugarcane bagasse, sawdust, cotton residues, and Napier grass) as growth media for container-grown Giant of Italy parsley. Fourier-transform infrared and laser-induced fluorescence spectra were used to characterize the humification extent in composts before and after the addition of charcoal at five inclusion rates (0%, 15%, 30%, 45%, and 60%, weight basis). Spectroscopic measurements identified absorption bands between 1625 and 1448 cm−1 specific to each of the 25 organic amendments evaluated. The most suitable amendments (composts made from sawdust and sugarcane bagasse) were associated with O–H stretching of phenols and aromatic rings. Charcoal addition to composts changed some of their physical characteristics, leading to increased nutrient availability in some cases. Experimental and calculated dry matter yield were compared via multiple linear regression and simple non-linear regression as a function of the spectroscopic and physicochemical (N, P, K, pH, EC, C, HLIF, C:N, CEC, HA:HA) properties of the organic amendments. Regression models accurately assigned high yields to the sawdust- and bagasse-based composts and low yields to the Napier grass- and cotton-based composts. Electrical conductivity (EC) was the main factor limiting potted-parsley productivity, an indication that efficient management of charcoal rate and compost EC levels can aid in predicting parsley yield.
