Cake fertilizer is not a single nitrogen fertilizer and potassium fertilizer. Cake fertilizer is an organic fertilizer, which is mainly made from plant residues. Cake fertilizer not only contains very rich nitrogen, phosphorus and potassium, but also other trace elements. It is a natural Good fertilizer.

Bean cake is also rich in nitrogen, phosphorus and potassium and other trace elements. After fertilization, the effect on soil pH is relatively small, which can improve soil properties and facilitate plant growth.

Compared with compound fertilizer, bean cake has stronger soil fertilizer retention ability, and long-term use will not appear the phenomenon of soil fertility decline and soil compaction, which is very suitable for urban flower-growing families who lack garden soil.

Can the cake fertilizer be directly mixed into the soil as a base fertilizer?

1. The cake fertilizer can be directly mixed into the soil as a base fertilizer, but it is not recommended. If it must be used as a base fertilizer, the amount used must not be too much, and it is advisable not to exceed 1% of the total soil amount.

2. Cake fertilizer can also be used as top-dressing fertilizer, but if it is used as top-dressing fertilizer, it usually needs to be fermented and decomposed before use, because cake fertilizer will generate a lot of heat after soil fermentation, which will easily cause the roots of crops to be burned.

3. Before the cake fertilizer is fermented, first crush it and pour it into the container, then add an appropriate amount of soil and mix it evenly, and then add water. The amount of water should be determined according to the amount of cake fertilizer and soil.
