How to Make Odor-Free Fish Intestine Fertilizer? Essential "Golden Fertilizer" Secrets for Beginners_Q&A on vegetable cultivation

For balcony vegetable growers or small home garden enthusiasts, fish intestine fertilizer is a "treasure organic fertilizer" — made from free fish intestines collected from vegetable markets, it is rich in nitrogen and phosphorus. It can make leafy vegetables lush and thick with dark green leaves, and fruits and melons sweet and juicy. However, many beginners hesitate to try it because they worry about the stench during fermentation. In fact, as long as you master 3 core skills, you can easily achieve the effect of odor-free fish intestine fertilizer. Beginners can succeed on the first try, completely saying goodbye to the "smelly fertilizer trouble".

First, let’s talk about why it’s worth taking the time to make fish intestine fertilizer. Fish intestines are common "waste materials" at fish stalls, which can be collected for free without any cost, saving money compared to buying chemical fertilizers. After fermentation, the nutrients are easily absorbed by plants. Spinach and Chinese cabbage grown with it grow 20% faster than those with ordinary fertilizers, and their leaves are more glossy. Moreover, organic nutrients can improve the soil; with long-term use, the soil will become more and more loose, and the vegetables grown will taste more fresh and sweet. More importantly, if the method is correct, fish intestine fertilizer is odor-free and does not attract insects, so you don’t have to worry about affecting the home environment at all.

The key question is: How to make fish intestine fertilizer without odor? This is the most concerned issue for beginners. Master these steps well, and you can ensure that the fish intestine fertilizer is odor-free. The first step is to do a good job of pre-treatment. When collecting fish intestines, be sure to ask the fish stall owner to help remove the gallbladder — if the gallbladder breaks, it will not only make the fertilizer bitter, but also easily breed bacteria and aggravate the odor, which is the "hidden killer" that causes fish intestine fertilizer to smell bad. After returning home, rinse the fish intestines briefly, drain the water and set them aside. There’s no need to cut them too finely, to avoid the outflow of juice which causes odor. This is the foundation for achieving odor-free fish intestine fertilizer.

Next is the core "layered deodorization fermentation method", which is the key step to make fish intestine fertilizer odor-free, and beginners can easily achieve it by following the steps. Prepare a 5-liter plastic bucket with a lid, ordinary garden soil, and orange peels or grapefruit peels (these are the "secret weapons" for making fish intestine fertilizer odor-free). First, spread a 5 cm thick layer of garden soil at the bottom of the bucket to separate the fish intestines from the bucket wall and reduce the leakage of odor. Then spread a 2-3 cm thick layer of fish intestines, and then completely cover the fish intestines with garden soil, making sure that no part of the fish intestines is exposed — the less contact with air, the lighter the odor, which is the core principle of odor-free fish intestine fertilizer. Alternate layers of "soil - fish intestines" until it is 10 cm away from the bucket mouth. Finally, spread a 10 cm thick layer of garden soil to seal the top, and put a few orange peels. The fresh fragrance of the peels can neutralize the remaining odor and further strengthen the effect of odor-free fish intestine fertilizer.

Sealing also requires attention. If this step is not done well, the efforts to make fish intestine fertilizer odor-free may be in vain. Tighten the bucket lid, but do not seal it completely. Use a needle to poke 3-5 small holes on the top of the lid to allow the gas produced during fermentation to escape, avoiding excessive pressure inside the bucket which may cause the bucket to burst, and at the same time preventing the accumulation of odor. Then place the bucket in a cool and ventilated corner of the balcony, and do not expose it to the sun. High temperature will accelerate the diffusion of odor and destroy the odor-free state of the fish intestine fertilizer.

Beginners also care about how to judge whether the fermentation is completed and whether the fermented fertilizer can still remain odor-free. In spring and summer, when the temperature is high, fermentation can be completed in about 1.5-2 months; in autumn and winter, when the temperature is low, it takes more than 3 months. When you open the bucket lid, if you can’t smell the fishy smell, but only the fresh fragrance of soil and fruit peels, and the fish intestines have completely decomposed and the soil has turned dark black, it means the fermentation is successful. Such fertilizer can always remain odor-free, so you can use it with more peace of mind.

Finally, let’s talk about the precautions for beginners when using it. The fermented fish intestine fertilizer is a high-concentration fertilizer, so it must be diluted — mix 1 spoonful of fertilizer with 10 times the amount of clear water, and pour it directly around the soil at the roots of vegetables. Do not splash it on the leaves to avoid burning the leaves. For leafy vegetables, water them once every 15 days; for fruits and vegetables such as tomatoes and peppers, use it before the bud formation period, which can promote flowering and fruit setting. There is no need to worry about odor throughout the process, because we have done every step to ensure the fish intestine fertilizer is odor-free.

Many beginners also worry about attracting insects. In fact, you can just sprinkle a layer of plant ash on the top soil layer. It can not only prevent insects but also supplement potassium, and at the same time, it will not affect the odor-free effect of the fish intestine fertilizer. By following this method, making odor-free fish intestine fertilizer is no longer a problem, and even beginners can easily do it. Next time you buy fish, remember to take the fish intestines home and try making this "golden fertilizer". The vegetables grown with this odor-free fish intestine fertilizer will definitely surprise you.
