3. How to use

Plant ash is a relatively common farmyard fertilizer, as well as an organic fertilizer and potassium fertilizer. The main ingredient in it is potassium carbonate, which contains relatively large amounts of potassium and phosphorus. It can be used as a root fertilizer or as a foliar fertilizer. When using, be careful not to use it together with phosphate fertilizers and acidic fertilizers.

1. Main ingredients

The main ingredient is potassium carbonate, which contains almost all the mineral elements found in plants. The potassium content in plant ash is relatively high, usually around 6%-12%, of which 90% is water-soluble and exists in the form of carbonate. The second is the content of phosphorus, which is usually around 1.5%-3%. In addition to these, it also contains iron, copper, magnesium, sulfur, zinc and other nutrients.

2. What is fertilizer

Plant ash can be used as fertilizer. It is also a relatively common farmyard manure. After use, it can sterilize and prevent diseases and insect pests. It is also an organic fertilizer, very suitable for acidic soil or clay, and can be used as a mulch for seedlings. Because it contains more potassium, it is also a potash fertilizer.

It is an alkaline fertilizer. Do not use it together with acidic fertilizers and farmyard manure. If you want to spray on the leaves, you need to filter it before use, so as not to cause pollution to the leaves and flowers of the plants.

3. How to use

Normally It can be used as a top dressing on the roots, or you can spray the leaves with a less concentrated liquid. It is suitable for potassium-loving plants such as sunflowers, potatoes, grapes, etc. When using it, do not mix it with phosphate fertilizer, as it may cause low fertilizer efficiency.
