Terra do quintal ou substrato? O erro que pode estar a matar as tuas plantas

Is backyard soil suitable for growing plants in pots? And how do you choose a good substrate for your vegetable garden? In this video, I explain, in a simple way, the science behind substrates: why some help plants grow better and others can leave the roots without air, waterlogged, or with difficulty absorbing nutrients. Often, when a plant turns yellow, weak, or doesn't develop as expected, the problem isn't the seed, the sun, or "lack of skill." It may be the medium in which the plant is growing. In this video you will learn: 🌱 the difference between garden soil and substrate 🪴 why growing in pots requires more care 💧 how water circulates within the substrate 🌬️ why roots also need to breathe 🧱 what macropores and micropores are 🌿 why organic matter is so important 🧲 how humus helps retain nutrients 💦 what leaching is 🧪 what cation exchange capacity means ✅ how to choose a suitable substrate for vegetable gardens This video is supported by Nutrofertil, a brand I have worked with for several years. Throughout the video I also show the Nutrofertil substrate for vegetable gardens, which I regularly use in my plantings, and explain what characteristics you should look for in a good substrate for pots, raised beds and horticultural crops. A good substrate is not just "soil in a bag". It should allow for a balance between water and air, promote root growth, help retain nutrients, and create better conditions for plant development.
