Slag is the waste residue left after burning coal. It contains certain trace elements, but it is difficult to absorb without processing. Let it burn fully first to ensure that no coal remains, and then remove the cokeed part. Strain the rest through a sieve to separate the coarse and fine residue. Fine slag mixed with soil can be used as a substrate, but do not put too much, accounting for one-third of the total. Coarse residue is difficult to absorb, but it can be placed on the bottom of the basin to increase drainage and breathability.

1. Full combustion

1. Full combustion

The slag itself is produced by the combustion of coal. However, the combustion is usually incomplete and there is still a certain amount of coal in it, which does not help the growth of the plants. So you need to burn it on one side first and burn the big pieces.

2. Selection

Burning If the time is too long, it will easily produce coke. Coke only contains carbon and no other nutrients, so it needs to be removed. The rest needs to be filtered through a sieve to separate the residues of different thicknesses, each of which has its own use.

3. Mix soil

Compared Fine slag should be mixed with soil, and it is not advisable to put too much fine slag. Although it contains trace elements, it also affects the drainage and air permeability of the soil. Generally, the composition of soil is more than two-thirds.

4. Pad on the bottom of the pelvis

Coarse slag is not easy for plants to absorb their nutrients, so it is only used at the bottom of the pot to increase the drainage and air permeability of the pot soil.
