Can necrotic leaves or roots of plants be used as fertilizer?

Overview:OK.

The premise is that it cannot be used as fertilizer for the same kind of plants.

Details:Because plant necrotic organs, including leaves or roots, not only contain cellulose, but also contain protein and a variety of minerals, and these substances can be decomposed by microorganisms, can release nitrogen and other macronutrients, but also contain a certain amount of trace elements, so plant necrotic leaves, roots and other organs can be used as fertilizer. For example:

Green manure is a typical example.

No matter what kind of plant necrotic organs are used as fertilizer, they must be fermented in advance, otherwise, direct application is easy to hurt the seedlings, and its nutrients are not easy to be absorbed.

[The author's room morning bell press words:Necrotic organs and tissues of the same type of plants cannot be treated as fertilizer. For example:

Necrotic watermelon vines cannot be used for watermelons, nor can they be used as fertilizer for all other Cucurbitaceae plants; The straw of a necrotic potato cannot be used as fertilizer for potatoes or plants of the Solanaceae family such as eggplants and tomatoes. The reason is that all kinds of necrotic plant organs carry a large number of germs or viruses, which are easy to cause disease proliferation.

If you want to use it as fertilizer, it is best to expose it to the sun for a few days, otherwise it is easy to get infected, especially for the same plant.

1. Plant necrotic leaves or roots generally contain harmful substances such as germs, which may be used as fertilizer, which may cause crops to be infected with germs and get sick again. Therefore, the remaining plants and diseased plants in the field should be cleaned up in time during the annual crop rotation.

2. Choice of fertilization: you can choose to use water-soluble fertilizer, water-soluble fertilizer is a healthier, high safety factor, and hormone-free water-soluble fertilizer, fast dissolution, high absorption rate, fertile leaf water-soluble fertilizer, flush fertilization, reasonable fertilization, not excessive fertilization, conducive to crop growth and development.

It depends on how the leaves of the plant die, if they die early and dry up, they can be used as fertilizer, if the leaves are invaded and necrotic by some foreign bacteria, then they cannot be used.

If you only use a small number of leaves, cut them into small pieces and bury them directly in the pot. If there are many leaves, they cannot be directly paved and used, and they must be fermented and corrupted first, otherwise the dead leaves will accumulate a lot of heat in the natural decay process, and the consequences for the plant can be imagined. The yellow leaves of bamboos are mainly due to poor drainage, and it is recommended to replace them with humus soil that is more conducive to drainage.

1. Slowly pour tap water into the pot for a long time, let the water dilute the fertilizer, and drain it from the bottom hole.

2. Change the soil, but it depends on whether the plants can change the soil in the summer, so as not to hurt the roots too heavily and cause death.

Compost is an organic fertilizer made by using animal and plant remains and excrement containing fertilizer components, plus soil and minerals, under high temperature and humid conditions, fermentation and decomposition, microbial decomposition and repentance. Compost is an ancient type of fertilizer that must be made by collecting the right materials, such as straw, stems, weeds, fallen leaves from trees or livestock manure, and then mixing them properly.

Add an appropriate amount of calcium cyanamide to promote its fermentation, and then cover it with broken mats, rags, straw or plastic cloth to avoid loss of fertilizer. Then every once in a while.

After about three or four weeks, you can move this compost into the field and start using it.
