Potential of Pine Bark to Replace Perlite in Coir-Based Substrates: Effects on ...
Dias, G.C.; Machado, R.M.; Alves-Pereira, I.; Ferreira, R.A.; Gruda, N.S.Enhancing the sustainability of growing media is an important objective in soilless vegetable cultivation. Here, we evaluated the potential of pine bark to replace perlite in coir-based substrates for lettuce (Lactuca sativa L. cv. ‘Godzilla’) cultivation. The experiment followed a factorial design with two coir-based substrate blends—one amended with perlite and the other with pine bark—and two nutrient soluti...
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...
An Alternative to Peat—Effects on Plant Growth, Phytochemical Accumulation, and...
Machado, Rui. M.A.; Alves-Pereira, Isabel; Ferreira, Rui; Gruda, N.S.In this study, we evaluated the effects of municipal solid waste compost supplemented with inorganic N on the physicochemical properties of soil, plant growth, nitrate concentration, and antioxidant activity in spinach. Experiments were carried out in neutral and acidic soils that were low in organic matter. A fertilized soil was used as a control, while four compost treatments—two compost rates of 35 and 70 t ...
