6 types of organic fertilizers readily available at home for growing clean vegetables.
(Baonghean.vn) - Organic fertilizer is very good for plants, especially for families who want to grow clean vegetables at home. Making your own organic fertilizer ensures effectiveness and saves costs... Below are some types of waste that can be used to make organic fertilizer.
1. Eggshell
Eggshells have many useful applications in vegetable growing and gardening. Eggshells are made up of over 95% minerals, including up to 37% calcium carbonate – an essential element for plant growth – along with significant amounts of magnesium, potassium, iron, and phosphorus.
Eggshells provide a rich source of calcium for plants. To utilize this material, you can crush or grind eggshells before mixing them into the soil so they decompose faster, helping the soil absorb nutrients more easily. In addition, eggshells neutralize pH levels, making the soil more porous and promoting faster plant growth and development. Importantly, both raw and cooked eggshells can be used as fertilizer.

2.Vbanana peel
Ripe banana peels are rich in potassium. You can dry the peels, then grind them into a powder and spread it on the soil. Alternatively, you can ferment the peels in water; soak 3 banana peels in 3 liters of water for about 3 days. Then, use this water to water your plants.
Banana peels can be used as a potassium fertilizer to promote plant growth, which is very good for home-grown vegetables or plants like tomatoes, eggplants, and some flowering plants such as begonias and primroses, helping them bloom quickly and last longer.This fertilizer provides nutrients to the plants, so only use enough for the entire season; do not overuse it.

3. Tea leaves, coffee grounds
Using used tea leaves and coffee grounds as fertilizer for potted plants and ornamental trees not only helps the soil retain moisture but also makes the plants healthier. This method is quite simple; just spread the used tea leaves or coffee grounds on the surface of the soil. Note that the water must be removed from these materials, only the solids should be used, as the tea water can cause the soil to lose its aeration. Also, do not pour hot used tea leaves directly onto the plants; let them cool before applying to avoid damaging them.
Plants that thrive in acidic soil, such as roses, sweet potatoes, potatoes, and aloe vera, greatly benefit from coffee grounds fertilizer. Similar to tea leaves, coffee grounds should be applied only after they have cooled. Additionally, coffee grounds can help deter snails and other insects.

4. Soybean pulp and coconut pulp
Families who regularly make soy milk and coconut oil can utilize the leftover pulp as fertilizer for their houseplants. Specifically, mix soybean pulp and coconut pulp in a 1:1 ratio with composted soil for about a month, then use it as fertilizer for plants. This fertilizer helps loosen the soil and increases its organic matter content.

5. Leftover food
After use, leftover food items such as vegetables, fruit peels, tea bags, rice water, etc., can all be saved and used as fertilizer. These materials should be stored and composted in styrofoam or plastic containers with lids. For fried foods containing oil, pour a layer of water to drain off the excess oil before adding them to the container. Keep the compost container away from living areas to avoid unpleasant odors, and stir the mixture once a day to facilitate decomposition.
The mixture can be left to ferment for a few weeks or longer. Afterwards, strain the liquid into another container to water the vegetables, and use the remaining composted residue as fertilizer for the plants in appropriate amounts.

6. Aquarium water
- Nowadays, many people use aquariums to decorate their homes and improve the feng shui. Each time you change the water in the aquarium, you should save some of it to water the plants. This water contains plenty of nitrogen and other nutrients that help the plants grow strong and healthy.
