But how to fertilize the soil and improve plant development without the traditional fertilizers? The report of GLOBO RURAL talked with several urban mints, who told us the methods, techniques, and recipes of organic fertilizers that they apply in their gardens:


One of the main animal friends from the garden, the worms are essential in the formation of a healthy soil, rich in nutrients. In a report in the Green Cities section, we show how the journalist Alex Branco, an urban gardener 35 years ago, set up a small- hole to produce humus and natural liquid biofertilizer.

The earthworm nursery is divided into three floors: in the first, the earthworms mix with the earth and with the remains of plants and leaves; In the second, the compounds deposited by the animals are dammed; The third floor stores the liquid that flows from the first three, used by Branco as a liquid biofertilizer.


The natural fertilizer tip of Cau? Azeredo is a solution based on nettles. He recommends harvesting the leaves of the plant and soaking them in a bucket of water for about a week, away from the sun or exposed to very low or very high temperatures. After seven days, Azeredo explains that it is necessary to remove the leaves from the water and dispense them, storing only the liquid, which can be sprayed weekly on the soil and vegetables in the garden. Finally, he reminds us that it is important not to forget to wear gloves when you collect the nettles!

Do not dispense crab shells, shrimp or lobster when lunch or dinner is over. The recommendation is from Mint S?lvia Salles, who has used shells of crustaceans as fertilizer for her garden for almost five years. She recommends opening a hole that is more than 40 cm deep in the soil and allowing the crustacean remains to remain on the ground for about a month. Then it is possible to remove them from the hole and place them on another piece of soil, repeating the process and obtaining the same results. The composting with crustacean shells benefits the land with a large amount of phosphorus and nitrogen.

Remains of fish

The parts of fish not used in meals, such as tails, heads, and entrails, be used to fertilize the soil, especially those in which plants that need a lot of nitrogen, such as corn and tomato, will be planted. The instructions are the same as for crustaceans: dig a hole with at least 40 cm depth and place the fish remains there, blocking the space and planting on top.

Coffee grounds

The idea of the mint Adalberto Ferrara is to enjoy everything you can in your home garden, made up of pots made with pet bottles and a fenced-in flowerbed with reused pallets. The fertilizer you use also agrees with and this thought. After brewing coffee, Ferrara disposes of the lees around the plants and seedlings of his garden. In addition to ward off slugs and snails, the coffee grounds are rich in phosphorus , potassium and nitrogen. Another option, according to the mint , is to dilute the remains of the coffee beans and create a liquid fertilizer , which can be sprayed once a day in the garden.


When weeding the yard, do not dispense the cut grass. Collect good handfuls and deal with the earth. In addition to leaving the environment greener, the herbs are a rich source of nitrogen. When it decomposes , the newly cut grass enriches the soil in which it was placed with various nutrients beneficial to the development of any vegetable.


Also known as comfrey or comfrey , the Symphytum officinale is rich in magnesium , potassium , phosphorus , and vitamins and minerals different. Cultivating the herb was the alternative that mint Viviana Frezarinni found to produce her own organic fertilizer . After being harvested, she recommends that the leaves be mixed with water – about half a glass of water per leaf – and left in the sun for one to three days. The water is then drained and the leaves applied directly to the soil.



Another product that goes into the trash, but can turn into an important organic fertilizer, since it is rich in calcium and potassium , is the eggshell . Claudio Poletto has used the technique for about three years and says that the method has drastically increased the resistance of plants and decreased the number of malevolent larvae to the development of plants . He recommends that the houses be washed, crushed into minute grains, and added to the surroundings of each seedling .

Wood Ash

Rich in potassium , phosphate and trace elements , the wood ash can be effective in increasing the resistance of plants, as well as combating pests . The tip of the mint Camila Fl?r is to mix the ashes – about a quarter of a cup – with a liter of water and spray in the vegetable garden once a month.


The most common method among urban miners , composting is a mixture of nitrogen-rich food and substance debris such as straw , grass and dry leaves . Mint Fabiana Mendes usually grinds the remains of food and mixes it with the substances already mentioned, adding and mixing everything to earth, before planting a new seedling. The mint Leandro Castelli prefers to put the compost on the soil, not inside it, and said to obtain good results with the method.

Animal husbandry

Another type of organic abound already widely used by urban miners is the dung of herbivorous animals such as cows , sheep and horses . What many people do not know is that animal waste can not be deposited on the land right away. They need to remain mixed and diluted in the water for at least two weeks, exposed to the sun for most of the day, explains the mint Samantha Kusniaruk, who is also trained in botany . After the time quoted above, you can use the liquid generated in the process to spray on the plants, as well as using the tanned manure to fertilize the soil . If the mint adds manure as soon as it is produced by the animal,
