Can lard residue be used as fertilizer?

Lard residue as fertilizer

Lard residue can be used as fertilizer, but it cannot be directly applied to the soil, otherwise it will cause plant seedlings to burn. It is best to wait until the lard residue is fermented and then stir the lard residue into the soil, which will be beneficial to the growth of plants.

Lard residue can be used as flower fertilizer. The oil and protein contained in lard residue will be decomposed into nitrogen, phosphorus and potassium elements and absorbed by the roots of plants. This way, less organic fertilizer needs to be applied. It is very suitable for applying to honeysuckle and ivy.

How to make fertilizer from lard residue

1. Composting: Vegetable lard residue and other vegetables can be poured on the ground or soil according to the amount, covered with a layer of soil, watered and fermented. If the amount is not large, the high temperature generated is not sterile and does not kill insects. It is best to expose it to the sun for a few days to kill insect eggs and bacterial damage.

2. Fertilization: Put the lard residue into a container and add a certain amount of water for distillation. The clear water after distillation can be used as top dressing, and the residue can be mixed into the soil as base fertilizer.

Key points for using lard residue fertilizer

1. Use after it is fully decomposed: Immature oil residue will burn the seedlings, cause the appearance of maggots where flies lay eggs, damage the roots of crops, and make the crops grow poorly.

2. Pay attention to controlling the concentration: add water in a certain proportion to dilute and lower the concentration before watering the flowers. It is recommended to do it in small amounts multiple times.
