Can lard residue be used as fertilizer? How to ferment lard into fertilizer?

Oil residue fertilizer is a high-quality farmyard manure made from the residue left after pressing and removing the oil from plant seeds that are rich in oil. It is usually used for crops with high economic value such as vegetables and fruit trees.

Oil residue can be used as fertilizer, but it needs to be fully fermented before it can be used for fertilization. It can make peanuts grow better, but if it is not fermented and directly contacts the roots of flowers, it may damage the roots of the plants.

Oil residue fertilizer production

When making oil residue fertilizer, you can add it directly to the bottom of the soil. After fermenting for 1-2 months, it can be applied as fertilizer. You can also mix it with the soil. Then add lime and pesticides, place it under the sun for fermentation, or mix it with clean water, put it in a sealed container, and ferment it in a cool and ventilated place. When using it, just take the clear liquid on the top.

Use of oil residue fertilizer

1. Long roots

When using oil residue fertilizer, be sure to add water to dilute it in proportion to reduce the concentration before normal fertilization can be carried out. However, it should be noted that it must be used in small amounts and multiple times to better play its role.

2. Insecticide

The application time can generally be chosen 3 weeks before sowing, because the residue fertilizer will generate high temperature when it decomposes and ferments in the soil, producing various organic acids, which can kill all pests in the soil.
