Nitrogen fertilizer is one of the nutrients necessary for plant growth, however, in home gardening, buying commercial nitrogen fertilizer can be a bit inconvenient. Therefore, it is necessary to find a way to replace nitrogen fertilizer at home. Here are a few alternatives to commercial nitrogen fertilizers to help you provide adequate nutrients to your plants.
Method 1: Use household food waste**
Kitchen waste, such as leaves, peels, leftovers, etc., is rich in organic matter and nitrogen, which can be used as nitrogen fertilizer for plants**. Put this food waste in a compost bin, add the right amount of water, and after a period of fermentation, you can get a nitrogen-rich fertilizer. The use of this fertilizer can provide adequate nutrients to the plants while also helping to improve soil quality.
Method 2: Use legume fertilizer**
Legumes are a very effective nitrogen fertilizer**. Put cooked soybeans, mung beans or black beans in a compost bin, add an appropriate amount of water, and ferment them to get a nitrogen-rich fertilizer. This fertilizer not only provides adequate nutrients to the plants, but also helps to improve the soil structure.
Method 3: Use plant ash**
Grass ash is a very effective potassium fertilizer and also contains a certain amount of nitrogen. Mix plant ash with an appropriate amount of water, stir well, and filter out the excess water to obtain a nitrogen-rich fertilizer. The use of this fertilizer provides adequate nutrients to the plants while also helping to strengthen the plant's resistance to disease.
Method 4: Use fish tank water**
Fish tank water is rich in organic matter and nutrients, which can be used as nitrogen fertilizer for plants**. After filtering out the bait and fish droppings in the fish tank, dilute them in a certain percentage and water the plants. This fertilizer not only provides adequate nutrients for the plants, but also helps to keep the water quality of the fish tank fresh.
