1. What is oil cake fertilizer?
Oil cake is a secondary product of the vegetable oil pressing process. There are many different types of oil cake such as: peanut oil cake, coconut oil cake, sesame oil cake…
Even though the oil cake is a waste, the oil cake still contains many useful nutrients for plants. Most nutrients are in high energy form, plants cannot “eat” them immediately. Therefore, if you process oil cake properly, you will get high quality oil cake fertilizer and organic fertilizer – a super fertilizer that any plant loves. The characteristic of oil cake fertilizer is that it dissolves slowly, so its use is limited for direct fertilization. If applied directly, people will find it has an unpleasant odor, creating a favorable environment for harmful microorganisms to act and affect plants.
Therefore, experts recommend applying oil cake fertilizer indirectly. Specifically, we need to soak or incubate according to the instructions. Before fertilizing, you should combine it with probiotics to eliminate odors. If you combine this fertilizer with composted manure, it will bring great results.
In short, oil cake fertilizer is a type of fertilizer composted from patented oil cake biological products. There are 2 types of oil cake fertilizer: powdered oil cake fertilizer (dry fertilizer) and organic protein compost from oil cake (water fertilizer). Depending on the purpose of use, people can choose the type of oil cake fertilizer and the appropriate composting method

8. Answering questions related to incubation of oil cake
Incubating oil cakes is not difficult, but not everyone can do it successfully. Therefore, there are still many questions surrounding this topic:
- How long can the oil cake be brewed? From 45 to 50 days from the time of incubation, you can use it! However, if you incubate the product with EM biological products, the incubation time will be shortened to 30 to 40 days.
- Signs that the oil cake has been successfully incubated? Your composting of oil cake has been successful if the product does not have a foul odor but has a light aroma of fermenting organic fertilizer. This type of fertilizer, when applied directly to the soil, will easily decompose, providing the soil with important and necessary nutrients.
- Should oil cakes be incubated with EM or with Trichoderma? People can use either of these two products. However, Trichoderma will be more effective: it helps to quickly decompose oil cake while minimizing odor. EM’s level of nutrient resolution is also not as effective as Trichoderma.
- What is the dosage of oil cake fertilizer for plants? For green vegetables, you should fertilize 1 kg of fertilizer for 5 to 7 m2 of land, and water periodically. If it is roses or orchids, fertilize with 200 to 300g of banh tam fertilizer/corner/month. Particularly for fruit trees, depending on whether the tree is large or small, we will fertilize from 500g to 2kg/root.
- What are common mistakes when composting oil cake? If you compost this type of organic fertilizer but cannot control the humidity, do not regularly stir the mixture or store the product in humid temperatures, it will lead to the compost stinking and degrading. Therefore, people remember to regularly check the compost mixture to promptly correct any errors.
