Vegetable manure for indoor cultivation

Vegetable manure for greenhouse cultivation is a natural fertilizer that enriches soils in macro and micro elements. This substance can be used to prevent and control pests and diseases. It consists of fragments of plants fermented in water, releasing the components they contain when decomposing. This type of solution has been used for some time in organic agriculture, domestic cultivation and permaculture practices. Many tend not to use manure, associating it with something disgusting. However, it is good to learn about this process, which makes it possible to avoid artificial products. This time, in this article, we will discuss use, preparation and properties of manure.

Vegetable manure for cultivation in a polytunnel

Such a concoction can be prepared with many species and varieties of plants. Although its smell is not very pleasant, it is impossible to deny the resulting positive effects. Importantly, manure is easy to prepare, free of charge, organic and natural. For most supporters of organic farming, it is one of the main method to fertilize and control pathogens under a garden tunnel. Depending on the type of substance, as well as its composition, it helps fight fungi and molds. It is effective when aphids, diaspines, mites, etc appear on a given site.

How to prepare manure?

The main rule to prepare manure is to immerse plants in water and let them ferment. Some preparations require mixing from time to time, in order for substances to be released from decaying green mass. When leaves break up, the substance is ready. It should be remembered that this is a highly concentrated preparation which could damage crops in undiluted form. Therefore, depending on the application, it must be incorporated in the right proportions. In polytunnels, the most commonly used manures are based on:

  • Nettle

1 kg of fresh plants without flowers is mixed with 10 l of water; the liquid is ready after 14 days. After this maturation time, one avails of a universal manure that can be used to feed most vegetables, trees and flowers. It is also recommended for lawns and potted plants. Effective against pests, to be diluted in a ratio of 1:20. When it comes to fungal diseases: 1:10.

  • Equisetum

Proportions will be similar to the previous one. Diluted (1:10), it provides soil with silicon, which is involved in the fight against pathogens and increase resistance of crops to mechanical damage.

  • Garlic

Mix 75 g of crushed garlic cloves with 0.5 kg of fresh leaves. Such a concoction is used to consolidate crops and fight against fungal diseases. It is often used when cultivating strawberries to eliminate mildew and fight against carrot fly. For crops and fruit trees, the preparation is diluted as 1:10.

  • Dandelion

In this case, you have two options for the preparation of the liquid manure: with or without flowers. With flowers, you get a liquid with a lot of phosphorus and potassium, ideal for acidic plants that produce fruits and flowers. The base without flowers is saturated with nitrogen, making it ideal for damaged soils. That way, the substrate is boosted: soil formation, minerals, release of nutrients.

  • Field horsetail

Plunge 1 kg of plants in 10 l of water, keep for 5 days during which the preparation must be mixed regularly. This one contains a lot of silicon, which strengthens plant cells and makes them more resistant to fungal attacks. To water plants, a ratio of 1: 5 is required and 1: 2 should be followed to control pests such as scale insects, red spider mite, or diaspididae. Importantly, horsetail manure does not smell as bad as others.

  • Elderberry

Mix 1 kg of shoots, flowers and leaves into 10 liters of water. After 5 days, the solution should be ready. If the plot is infested with moles or voles, this black mixture can be introduced into mounds and holes. Its smell has a deterrent effect on animals, discouraging them from settling in sites where the liquid is used.

  • Tansy

Add 1 kg of finely chopped leaves in 10 liters of water, then mix, allowing to ferment for 20 days. After this delay, the liquid manure should be ready. Undiluted, it is used on ants to eliminate them. If larvae infest the soil, this mixture will remove them. In that case, the substance should be mixed with the soil.

Biological cultivation in a polytunnel

Vegetable manure effectively replaces artificial pesticides for indoor cultivation. These weedkillers, although very effective, are also toxic. This is why it is beneficial to look for natural compositions before resorting to harmful means. For this reason, there is now a growing interest in these biological solutions.
