Can vegetable oil be used as fertilizer?

Vegetable oil as fertilizer

Vegetable oil can be used as fertilizer, or it can be used directly as fertilizer. Adding a small amount of vegetable oil around the soil of the original plant can slowly make the soil more fertile. The fertilizer effect lasts for a long time and is suitable for the growth of perennial plants.

Vegetable oil can be used as flower fertilizer, but because it takes a long time to decompose, it is best to add it to the soil before planting flowers. After a period of decomposition, the flowers can be planted. It can be used as a fertilizer for flowers and is suitable for growing flowers such as roses or peonies that are suitable for fertile soil.

How to make fertilizer from vegetable oil

1. Make holes in the soil

Vegetable oil cannot be directly poured near the roots of the plants, as this will cause the soil to have poor air permeability and easily breed pests. First, you need to poke a few small holes at the edge of the soil.

2. Pour a small amount of vegetable oil

Then pour a small amount of vegetable oil into the small holes, just enough to cover the mouth of the holes. Too much vegetable oil will cause the soil concentration to be too high, which is harmful to plants.

Key points for using vegetable oil fertilizer

1. Use in small amounts

Vegetable oil is a solution with a high organic matter content. If too much is applied, it can easily cause the roots to absorb water back into the soil, causing the plant to dry out or even die.

2. Do not use near plants

If vegetable oil is used near plants, it may seep into the soil and form an oil film near the roots of the plants, which will make it difficult for the roots of the plants to breathe and easily cause them to wither and die.
