Exploring Sustainable Fertilization Strategies Involving Biochar, Compost, and ...
Machado, R.M.A.; Alves-Pereira, I; Velez, D; Grilo, A; Veríssimo, I; Ferreira, RThe effect of fertilization strategies involving biochar, compost, and inorganic N on growth and phytochemical accumulation in turnips was studied in a greenhouse pot experiment. The experiment was carried out with six fertilizer treatments: unfertilized soil (US), compost (120 g/pot) + biochar (20 g/pot) (C + B), compost (120 g/pot) + 0.5 g N/pot (C + 0.5 N), biochar (20 g/pot) + 0.5 g N/pot (B + 0.5 N), compo...
Enhancing the sustainability of growing media: exploring pine bark as a perlite...
Dias, Gonçalo C.S.; Machado, R.M.A.; Alves-Pereira, I.; Ferreira, R.M.A.Increasing the sustainability of growing media constituents is a priority nowadays. This study aimed to evaluate whether pine bark can replace perlite in coir- based substrates. For this purpose, an experiment was carried out with four treatments: two coir-based mixes, one containing perlite and the other pine bark, and two electrical conductivities of nutrient solution (1.5±0.2 and 2.5±0.2 dS m-1). Lettuce pla...
Influence of co-applying biochar, compost and inorganic nitrogen on growth, nut...
Machado, R.M.A.; Alves-Pereira, I.; Velez, D.; Grilo, A.; Ferreira, R. M. A.In the pursuit of sustainable vegetable farming methods, the effect of co-application of biochar, compost, and a reduced amount of inorganic nitrogen on growth and the quality of turnips was studied in a greenhouse pot experiment. The experiment was carried out with six fertilizer treatments: unfertilized soil (US), compost + biochar (C+B), compost + 0.5 g N pot-1 (C+0.5N), biochar + 0.5 g N pot-1 (C+0.5N), com...
Effects of reusing coir-based substrates with municipal compost and biochar on ...
Machado, R.M.A.; Alves-Pereira, I.; Alves, I.; Ferreira, R.M.A.This research aimed to evaluate the influence of reusing as growing media, five blends of coir, with municipal organic compost, biochar, perlite and pine bark on growth and phytochemical accumulation in lettuce. The tested growing media blends were coir (new) and four reused mixtures: coir: biochar: perlite, coir: compost: perlite, coir: biochar: pine bark, and coir: compost: pine bark. All mixtures had already...

Coir-Based Growing Media with Municipal Compost and Biochar and Their Impacts o...
Martins, T.C.; Machado, R.M.A.; Alves-Pereira, Isabel; Ferreira, R.; Gruda, N.S.The purpose of this study was to develop substrates with little or no peat by combining coir-based growing media with municipal compost and/or acacia biochar, two locally produced renewable resources, and to assess their effects on lettuce seedling emergence and growth, as well as their content in photosynthetic pigments and total phenols. Two experiments were carried out, the first with six mixes using compost...
