Nitrogen is an essential plant growth component and plays a vital role in the development of healthy foliage. While you can buy chemical fertilizers that are high in nitrogen, you can also make natural organic fertilizers by understanding natural products that are high in nitrogen and can be mixed with the soil.
Step
Step 1. Use compost
Compost is organic matter that has decomposed / decomposed. Compost piles usually contain a variety of nutrients that benefit plants, including potassium, phosphorus, and nitrogen. Regarding nitrogen, the bacteria in the compost break down the substance into ammonium, which other bacteria convert into nitrate so that it can be absorbed by plant roots. Compost is made up of a lot of nitrogen-rich material, including leafy greens, other vegetables, and moist fruit that supplies a lot of nitrogen to the fertilized soil.
Step 2. Add the composted coffee grounds
Coffee grounds can be mixed directly with the soil, or first added to the compost heap. Coffee grounds contain as much as 2% nitrogen by volume, which is high for a nitrogen-containing material. In addition, although some people are worried about the acid content of coffee, this only applies to coffee beans. Coffee grounds that remain after brewing, usually have a pH close to neutral, which is around 6.5-6.8.
You can add coffee grounds directly to the soil by mixing the damp powder into the soil by spreading it over the soil surface and then covering it with organic mulch
Step 3. Try using composted manure
Sheep, cow, and pig manure contains the most nitrogen, followed by poultry and dairy cow manure. Horse manure also contains nitrogen, but its concentration is much lower than that of other animals. Composted animal manure is better to use because the bacteria have started to break down the nitrogen into a form that plants can absorb.
Be aware, the use of animal waste has its drawbacks. Animal manure tends to increase the salt content in the soil, and the use of animal manure will increase weed growth
Step 4. Mix the blood meal to get instant fertilizer
Blood meal aka blood meal is an organic product made from dried blood, and contains a total of 13 percent nitrogen. This amount is quite large for the fertilizer component. You can use blood meal as a nitrogen fertilizer by sprinkling it over the soil and then watering it with water to dissolve it, or you can mix blood meal with water and use the solution as a liquid fertilizer.
- Because of its fast action, blood meal is an excellent source of nitrogen for nutrient-dense crops, such as lettuce or corn.
- Blood meal can also be used as a component in compost or other organic matter accelerators because it increases the speed of the decomposition process.
Step 5. Carefully feed the cotton seed meal
This fertilizer component is made from powdered seeds of the cotton plant. Some people consider it the second best nitrogen source after blood meal. However, unlike blood meal, cotton seed meal does not break down quickly so it takes a long time for plants to get nitrogen.
The biggest disadvantage of cotton seed flour is its negative impact on soil pH. This material makes the soil very acidic. Therefore, you need to monitor the pH level of the soil carefully if you want to make organic fertilizer from this material
Step 6. Use crab meal, feather meal, or leather meal for a slow-acting fertilizer
This product is made from crab powder, feathers, and cowhide, and each ingredient contains a large amount of nitrogen. However, all of these components break down in a relatively long time, and will not provide enough nitrate for plants that eat quickly. However, this material is quite good as a fertilizer or compost mixture because it can maintain a constant nitrogen content throughout the growing period.
Step 7. Try using biosolids and wood
Biosolids and processed wood materials such as sawdust, wood chips, and sewer waste (which need to be processed before being used as fertilizer) contain nitrogen and can be used as fertilizer. It's just that you have to make sure the biosolids used have been processed. Otherwise, this fertilizer will provide more risks than benefits. Furthermore, there are many fertilizers that are better than biosolids and wood because these materials decompose slowly and produce little nitrogen. However, these two fertilizers still provide the nutrients the soil needs. Wood debris also adds a "harbor" for plants.
Step 8. Plant nitrogen-fixing plants
Certain plants, such as legumes and clover, store nitrogen in their root nodules. These nodules release nitrogen into the soil gradually while the plant is alive, and when the plant dies, improving overall soil quality.
- Just toss the beans on the ground. Many people suggest green beans because they are not very big but grow fast.
- Try plowing the soil to get nitrogen back into it. When settling your plot in the seventh year, spread the green beans. Do not harvest green beans, and allow the seeds to fall to the ground to adjust for nitrogen levels, especially if you are going to plant a high-eating crop, such as corn in the following year.
