Can potassium nitrate be used as fertilizer?

Potassium nitrate as fertilizer

Potassium nitrate can be used as a fertilizer, and can be used directly as a fertilizer. It contains a large amount of potassium and magnesium elements, which can supplement the organic matter needed for plant growth. Applying it to the soil can improve the fertility of the soil.

Potassium nitrate can be used as flower fertilizer. If it needs to be decomposed quickly during use, it can also be mixed with water and used by irrigating it into the soil. It can be used as a fertilizer for growing flowers. It is generally suitable for growing roses, kalanchoe, Clivia and other flowers.

How to make potassium nitrate fertilizer

1. Mix water

Potassium nitrate can be applied directly to the soil, but its decomposition rate is slightly slow. If it is water-soluble, its speed of action can be greatly increased. The first step is to prepare the aqueous solution.

2. Sprinkler or watering

After the potassium nitrate aqueous solution is prepared, you can choose to use a watering can to water it and spray it on the leaves of the plant, or you can choose to water it in the growing soil of the plant and use it as topdressing.

Key points for using potassium nitrate fertilizer

1. Choose flowers

Potassium nitrate is a fertilizer that contains a lot of potassium. Although it also contains nitrogen and magnesium, if it is used for a long time on flowers that do not need potassium, it will easily cause excessive potassium in the soil, which will cause adverse effects.

2. Watering location

When watering, keep potassium nitrate aqueous fertilizer as far away from the roots of the plants as possible to avoid instantaneous excessive soil concentration, which will cause reverse water absorption and root dehydration, and even plant death.
