Add brown sugar

1. First of all, the retting is not fully retched before it has a taste. The really fermented fertilizer has only a little sour taste and no odor. Brown sugar can accelerate fermentation and shorten the odor stage in the fermentation process

2. Acidic fermentation is good. If you are not sure about pH, you can buy a bag of pH test paper to test yourself. The following figure shows the fully fermented, with a pH value of about 3

Add orange peel

1. Chop orange peel, grapefruit peel and orange peel into small pieces and pour them into a container for composting. Such retting fertilizer not only has a small odor, but also has a faint fragrance

2. Unscrew the lid once every 4 or 5 days at the beginning, once a week after half a month, then once a month, and then don't put it later. More gas is produced at the beginning and less and less at the back

Retting for 2 months, unscrew the cover and smell it. If there is no smell, it can be used

Add EM bacteria

1. EM bacteria are commonly used in agriculture. When composting, pour some EM bacteria into the barrel to speed up the fermentation and eliminate the odor

2. The following figure shows the results of fermentation for one week after using EM bacteria. In the jar are all kinds of fruit peels and fruit dregs left after juicing. You can see that they have basically begun to soften and rot

Put a glass seal at the mouth of the bottle. It can be used in a month. There is no smell at all

Add distiller's grains

1. Distiller's grains contain a lot of lactic acid bacteria and yeast, which is a natural starter. When composting, pour a little distiller's grains into it, which can greatly shorten the composting time

2. Composting after adding distiller's grains will not stink, but will have a faint aroma of wine. For example, the composting in the figure below adopts the sandwich composting method, that is, a layer of soil, a layer of kitchen waste, and another layer of soil... After adding distiller's grains in the middle, colonies grow in a week, and the kitchen waste in the middle is also quickly retted

Add oleander leaves

1. Oleander is poisonous. Everyone must know it. Adding oleander leaves during composting can kill insect eggs and disperse small insects

2. Crush the oleander leaves, put them directly into the compost barrel and stir them

Add quicklime

1. Flower friends often complain that their hard retting fat has given birth to insects, so they have to throw it away. In fact, you can add some quicklime powder to the composting bucket

2. With quicklime, it can not only sterilize and disinfect, but also contain a large amount of calcium fertilizer, which can supplement nutrition for plants in the later stage
