La organic material plays a leading role in the healthy development of plants, as it improves the quality of the substrate, provides nutrients, stimulates microbial activity, and contributes to environmental sustainability. Understanding how enrich your plants with organic matter It is key to keeping them looking vigorous, healthy and resistant, both in gardens and in urban orchards or indoor plants.
Why is organic matter so essential for plants?
When looking for plants to thrive, one of the most repeated pieces of advice is to ensure well-aerated soil, with drainage capacity, but also rich in organic matterThis is because organic matter performs several vital functions:
- Water retention: It acts like a sponge, improving the soil's ability to absorb and retain moisture, ensuring that roots have a constant supply without waterlogging.
- Facilitates aeration: The presence of organic matter makes the substrate less compact. This allows oxygen to reach the root zone, promoting essential metabolic processes and plant growth.
- Contribution of essential nutrients: During the decomposition process, organic matter releases key nutrients such as nitrogen, phosphorus, and potassium, which are essential for plant growth. It also creates and increases humus, which stabilizes soil structure and reduces erosion.
- Stimulation of microbial life: Microorganisms (bacteria, fungi, worms, etc.) that feed on organic matter promote a balanced ecological environment, benefiting plant health and contributing to the natural suppression of pathogens.
- Carbon storage: The use of organic matter helps to sequester carbon in the soil, which helps reduce carbon dioxide emissions into the atmosphere, thus contributing to the fight against climate change.
What makes up organic matter in gardening?
For organic matter to fulfill its functions, it must be composed of a series of elements and substances. These are organic waste of animal and plant origin, microorganisms and complex substances:
- Plant remains: Includes dried leaves, shredded branches, pruning remains, grass clippings, withered flowers, and leftover plant material after harvesting.
- Waste of animal origin: Manure from herbivorous animals (cow, horse, chicken, rabbit), as well as waste derived from agriculture and livestock.
- Microorganisms: Bacteria, fungi, yeasts, worms and other soil organisms responsible for the decomposition of matter and its transformation into nutrients that can be assimilated by plants.
- Complex chemicals: Such as humic and fulvic acids, which improve soil structure and its ability to retain nutrients and water.
These components vary depending on the preparation method and the ingredients used. In all cases, balance and proper maturation ensure a compost or organic fertilizer quality.
Advantages of using organic matter and homemade organic fertilizers
The use of organic fertilizers made from organic matter offers multiple benefits for both plants and the environment. Among the most notable advantages are:
- Increases soil fertility: It improves nutrient retention, stimulates microbial life, and creates an ideal environment for root development.
- Reduces the need for chemical fertilizers: It reduces dependence on synthetic products, promoting more sustainable and environmentally friendly gardening and farming.
- Prevents soil erosion and wear: Strengthens the structure and water retention capacity, helping to maintain long-term fertility.
- Facilitates waste recycling: Turning organic household or garden waste into compost helps reduce the amount of trash and the ecological footprint of the home.
- Protects plants from pests and diseases: Healthy, balanced soil increases plants' natural resistance to external agents, reducing the need for pesticides.
How to add organic matter to plants: practical and effective methods
There are several ways to enrich the substrate and improve plant vitality using natural or processed organic matter. Here are the most effective and practical methods:
Compost application
El compost It is one of the most popular and easiest fertilizers to produce or acquire. It is made by the decomposition of plant and animal waste in the presence of oxygen. You can buy mature compost at specialty stores, or better yet, make it at home with your own organic waste. This practice reduces the volume of household waste and ensures a balanced and personalized nutrient intake.
Compost must be well "cured," meaning it must have fully decomposed to avoid unpleasant odors or the presence of pathogens. You can consult our complete guide for make homemade compost.
animal manure
El manure Fertilizer derived from herbivorous animals (cattle, horses, chickens, rabbits) is a high-value traditional fertilizer. It is used fresh or, preferably, fermented or composted to prevent the presence of harmful microorganisms and neutralize unpleasant odors. This fertilizer is rich in nitrogen, phosphorus, and organic matter, improving both soil fertility and structure.
Plant residues and pruning remains
Los pruning remains, grass clippings and dry leaves They can be mixed with the substrate to create natural fertilizer, always ensuring that they are not infected with fungi or pests to avoid spreading problems. This material, once crushed or chopped, provides carbon, nutrients, and helps aerate the soil.
Layer of mulch or mulch
El mulching Mulching involves covering the soil surface with organic materials such as wood chips, coconut fiber, straw, bark, dry leaves, or mature compost. This protects plant roots from extreme temperatures, reduces evaporation, and, as the plant gradually decomposes, adds organic matter and nutrients.
cover crops
Sow cover crops Such as clover, alfalfa, vetch, and mustard help improve soil quality, prevent erosion, and attract pollinators. When incorporated into the soil before flowering, they enrich the substrate with fresh organic matter and nitrogen, benefiting the main crops.
Crop rotation
La crop rotation In vegetable or container gardens, it prevents nutrient depletion, facilitates the incorporation of waste from different species, and reduces the risk of disease. Alternating crops from different families allows for more rational use of the land and a gradual increase in available organic matter.
How to make homemade organic fertilizer step by step
To elaborate organic fertilizer at home It's simple and very rewarding. Here's a step-by-step guide based on the most recommended methods:
- Choose the right place and container: Choose a well-ventilated, partially shaded area. You can use a compost bin, a wooden box, or a tub with drainage and aeration holes.
- Prepare the foundation: Place a 10-15 cm layer of “brown” (carbon-rich) material, such as dry leaves, thin twigs, brown cardboard, or wood chips.
- Alternate layers of green and brown materials: Add kitchen scraps such as fruits, vegetables, coffee grounds, and crushed eggshells ("green" material, rich in nitrogen), followed by a layer of brown material. Maintain a ratio of 3 parts brown to 1 part green for an optimal balance of carbon and nitrogen.
- Regulates humidity: Lightly moisten each layer so the pile resembles a wrung-out sponge. Avoid excess water to prevent unpleasant odors and rot.
- Oxygenates and removes: Stir the mixture every one or two weeks using a shovel or rake to promote oxygenation and accelerate the decomposition process.
- Control the temperature: It is normal for compost to reach high temperatures during the process (it can exceed 45°C), which is a sign of active decomposition and sanitization of the final product.
- Wait the necessary time: The compost will be ready in 2 to 6 months, depending on the climate, batch size, and materials. When it has a dark color, a loose texture, and a forest-like scent, you can apply it to your plants.
Recommended materials and other homemade tricks
- Banana peels: They are a rich source of potassium and phosphorus, ideal for root and fruit development. You can chop them up and bury them directly in the substrate.
- Coffee grounds: They provide nitrogen, improve drainage, and attract worms. Use them sparingly and mix them in to prevent compaction.
- Crushed eggshells: They are an excellent natural source of calcium and even act as a barrier against snails and slugs if spread on the surface.
- Dry leaves: Shred leaves and alternate layers with green waste to create balanced compost and enhance microbial activity.
- Cardboard and inkless paper: They can be added in pieces as an additional source of carbon.
Materials to avoid in home compost
- Animal waste such as meat, bones, and dairy products, which attract pests and produce unpleasant odors.
- Remains of diseased or infested plants, to prevent the spread of pathogens.
- Plants with mature seeds (can germinate in finished compost).
- Coal ash, chemically treated products, or pet droppings.
Vermicompost and worm castings: high-quality organic fertilizer
El vermicompost o earthworm humus It is the result of the decomposition of organic matter by worms (Eisenia foetida or Californian red worm). It can be produced at home using a vermicomposter and offers several useful products:
- Solid humus: It has the appearance of loose soil, is rich in nutrients and beneficial microorganisms, and improves soil structure.
- Leachate (liquid humus): The liquid collected from the vermicomposter serves as organic fertilizer for irrigation.
Worm castings are particularly recommended for potted plants, urban gardens, and organic farming.
Troubleshooting organic fertilizer production
- Ammonia smell: Excess "green" material (nitrogen). Add more dry leaves or "brown" material.
- Rotten smell: Lack of oxygen or excess moisture. Stir and add dry materials.
- Very dry compost: Add green waste or water lightly.
- Appearance of insects: Cover the surface with dry leaves or a final layer of brown material.
Eco-friendly tips to boost the health and sustainability of your plants
- Use only organic and homemade fertilizers: They provide nutrients naturally, improve the soil in the long term, and avoid harmful chemicals.
- Pest control the natural way: Use homemade solutions such as garlic or onion infusions, or grow aromatic plants (mint, basil, rosemary) to repel insects.
- Sustainable irrigation: Take advantage of rainwater or reuse water from washing fruits and vegetables.
- Opt for sustainable pots and containers: Choose recycled materials, ceramics or clay instead of plastics.
- Respect the natural cycle of each plant: Learn about their specific light, water, and nutrient needs so they can grow in harmony with their environment.
- Mulching: It protects roots, retains moisture, and continuously adds nutrients as it decomposes.
Enrich your plants with organic matter It's a fundamental strategy for growing productive crops, vibrant ornamentals, or self-sufficient urban gardens. Reusing household and technical waste through composting, vermicomposting, or mulching allows us to care for plants in an ecological way, saving resources and reducing our environmental impact, ensuring healthier and more sustainable gardens and harvests year after year.
