How to make alum fertilizer water

Friends who like to grow flowers should have heard of the word "alum fertilizer water", which is a kind of organic fertilizer liquid mixed with ferrous sulfate. After full fermentation, it becomes dark green with sour taste, and it can promote growth and make leaves turn green like oil. However, when making alum fertilizer water, it often produces stench in the fermentation process of organic fertilizer. Therefore, everyone is afraid to make alum fertilizer water indoors, mostly in open places with good outdoor air circulation. Do you have alum fat water that doesn't stink? Yes, I'll teach you how to make the simplest alum fertilizer. It doesn't stink at all. Can be made indoors and raise acidic flowers and plants. It grows well, the leaves are green and shiny, and it is more ornamental.

Making material

A 5-liter oil drum, 0.5 kg of orange peel, 0.5 kg of banana peel or apple peel (one or more other peels are acceptable, but the total amount cannot exceed the amount of orange peel), 5 g of compound fertilizer and 5 g of ferrous sulfate.

manufacturing method

1, cut all kinds of peels.

Cut the prepared peel into pieces with scissors, not too much, as long as it can be put into the oil drum.

Step 2 throw bottles

Put the cut skin and compound fertilizer into an oil drum and fill it with water. Don't fill it with water, just three-quarters of the volume of the oil drum. If the water is too full, an accident may occur during fermentation.

Step 3 ferment

Cover the prepared oil drum, put it in a warm and well-lit place for fermentation for 3 days, then add 5 grams of ferrous sulfate, cover and stir evenly, and continue fermentation. At this time, attention should be paid to fermentation, and the lid should be opened and deflated the next day to prevent the gas in the bottle from exploding too much.

4, made of alum fertilizer and water.

The mixture in the oil drum is fermented until it does not produce gas (it may take about 3 months in winter and 1 month in summer). At this time, the liquid in the bottle becomes dark green, which is what we call alum fat water.

Step 5 use

Through our introduction, I believe everyone has a deeper understanding of the production method of alum fertilizer water.
