1. How to make your own potassium fertilizer
Potassium is one of the 17 essential elements needed for plant growth. If there is a lack of potassium, the leaves of the plant will appear spotty and the tips of the leaves will dry up, so pay attention to the application of potassium fertilizers. Now many potash fertilizers are chemical fertilizers. In fact, natural potash fertilizers can also be made by themselves. Here are some ways to make natural potash fertilizers:
1. Method 1
Prepare the fruit peels and rotten vegetable leaves, put them in the bucket, then add two-thirds of the bucket’s capacity of sand and soil, mix evenly, seal the bucket with film, and let it ferment for about 1-2 months. It can be used as potash fertilizer, or directly used as loam for growing plants.
2, Method 2
Twigs, straws, leaves, tea leaves, fruit peels, wood, etc. are all rich in potassium, which can be used in these raw materials. Put any kind of ash into the bucket, set it on fire, and burn it off. The remaining ashes are plant ash, which is a good potash fertilizer. It can be applied directly to the soil surface, or you can take out part of the ash and mix it with water and stir, and then take out the upper layer after precipitation. A clearer liquid is used for watering the flowers.
3. Method 3
The remaining tea water after drinking tea, rice washing water and the water after cleaning the milk bottle are rich in potassium, which can be used for Use directly for watering flowers.
4. Method 4
Rinse the egg shell with clean water, crush it, and mix it with sand in a ratio of 1:3.
5. Method 5
Prepare chicken and fish bones, rinse them with water, soak them for 12 hours, and then use a pressure cooker to steam the bones After about 20-30 minutes, take out and crush the bones with a wooden pestle, add half of the sand and stir well after it has been decomposed.
2. What raw materials are used for homemade potash fertilizers
Potassium fertilizers used on a large scale in industry are generally made from potash mines, including potash salts , anhydrous kaleite, kaleite, carnallite, potassium-containing well water, lake water and brine, etc. If you make your own sylvite, you mainly use the common raw materials in life, including:
1. Woody raw materials, including tree branches, corn straw stalks, leaves, tea leaves, wood, peanut bran, etc., preferably hardwood.
2. Bone raw materials: fish bones, chicken bones, egg shells, etc.
3. Water: tea water, rice water, and water for cleaning milk bottles.
4. Peel: fruit peel, rotten vegetable leaves, etc. Among them, banana peel is more commonly used.
