Nitrogen Rich Organic Fertilizer

Unlocking the Potential of Nitrogen Rich Organic Fertilizers: A Comprehensive Guide

Nitrogen rich organic fertilizers might be animal, plant, or manure based.

Plant-Based Organic Nitrogen Sources

Organic soil supplements derived from plants are known as Plant-Based Organic Nitrogen Sources, such as alfalfa meal, soy meal, and cottonseed meal, are light and will not attract animals when placed into the soil or potting mix.

These are typically balanced organic fertilizers, providing just trace levels of potassium and phosphorus in addition to nitrogen. Plant-based organic nitrogen sources are less concentrated and contain a smaller percentage of nitrogen than animal-based organic nitrogen sources, requiring higher application rates.

They also only function well in warm soil since they depend on an active soil food web to release their nutrients. These are soil amendments for the summer. When utilizing a plant-based organic nitrogen fertilizer, soil temperatures should be at 10–15° C or above for best effects.

Animal-Based Organic Nitrogen sources

Animal-based organic nitrogen Sources are the greatest choice for a high nitrogen organic fertilizer. These include cattle sector byproducts (blood meal), poultry industry byproducts (feather meal), fisheries byproducts (fish meal, crab meal, shrimp meal), warm casting, and bat guano. Fertilizers made from animals perform best in the cool months of spring and fall because they release their nutrients more quickly than organic fertilizers made from plants or the majority of manure.

They are beneficial when growing vegetables in containers since the little soil volume frequently require a high organic nitrogen fertilizer to maintain leafy growth. They are also useful when soils are weak or depleted.

A blood meal is an example of an animal-based organic nitrogen fertilizer that, if used improperly or too close to established plants, can “burn” the delicate vegetable roots. They should be mixed into the soil a few days before planting to avoid this. If you don’t have time to wait, mix them completely in a 5-gallon compost bucket, topdress the area around the plants, and lightly push a garden claw into the top inch or two (2-5 cm) of soil.

Keep your distance from plant stems at least 6″ (15 cm). After cultivation, thoroughly water with a water wand or an overhead sprinkler. Animal-based fertilizers may attract rats, raccoons, opossums, and other unwanted nocturnal visitors in addition to burning roots.

Manure-Based Organic Nitrogen sources

Composted animal manures, like poultry manure, are an excellent source of nitrogen for organic gardens. It is critical to age or compost manure before using it in organic vegetable gardens, especially where food comes into touch with the soil. Composting destroys or degrades pathogens such as E. coli and salmonella.

1. Compost

Kitchen scraps and yard debris, such as banana peels, orange rinds, grass clippings, and raked leaves, are used to make compost. Compost, which may be prepared from kitchen scraps and yard trash, adds nitrogen and other nutrients to your garden soil. Compost contains between 1.5% and 3.5% nitrogen. It is a slow-release fertilizer containing phosphorus and potassium.

2. Bat Guano

Bat guano is a good source of nitrogen, comprising 5.5% to 8% nitrogen by weight. A good portion of nitrogen, some phosphorous, and some potassium are all present in bat guano, making it a well-balanced fertilizer.

Because it is difficult to locate bat guano on your own, you will most likely need to purchase it from a store or online. The effectiveness of bat guano lasts for about a month and has a slow release time. One problem with bat guano is that it has a low pH. (very acidic). Because of the quick pH change, it should be used carefully to prevent burning your plants.

Only use bat guano directly in high-pH soils. Otherwise, you’ll have to include it in your compost pile to decrease the acidity.

The excrement from bats can eventually be used as a source of rock phosphate when it hardens into rock strata, which is interesting information that you should know (Rock phosphate is frequently used in fertilizers to provide plants with phosphorus.) Bat guano also includes 4% to 8.6% phosphate and 1.5% potassium by weight, making it an excellent all-purpose fertilizer with ample of each component.

3. Fish Emulsion

Nitrogen Rich Organic Fertilizer

Fish emulsion is made from the byproducts of fish processing for fish oil or fish meal. The leftovers of fish that have been processed for fish oil or fish meal are used to make a fish emulsion. Because fish emulsion contains 5% nitrogen by weight, it is a better nitrogen source than most types of manure and compost.

Furthermore, 1% of phosphorus and 1% of potassium are present in the fish emulsion. It is quick to release and lasts for two weeks. You can either spray fish emulsion on the foliage (for foliar feeding) or apply a diluted solution to the soil.

4. Cottonseed Meal

Nitrogen Rich Organic Fertilizer

Cottonseed meal is the byproduct of extracting cottonseed oil from cotton seeds. Cottonseed meal contains 4% to 6% nitrogen by weight, making it superior to most manure and compost. Cottonseed meal is created from the residue after the seeds and oil have been extracted.

Cottonseed meal has a slow to medium rate of release and lasts between 4 and 6 weeks. Because cottonseed oil is slightly acidic, it’s best to mix it into compost instead of applying it directly to plants. Cottonseed oil also includes 2.5% to 3% phosphorus by weight and 1.6% potassium by weight, making it a well-balanced fertilizer that is a solid all-around supply of the key three nutrients.

5. Soybean Meal

Nitrogen Rich Organic Fertilizer

People and animals consume soybean meal as a protein and energy source. Soybean meal is prepared by first extracting soybean oil from the beans. Ground soybean husks may be present in soybean meals.

Soybean meal has a nitrogen content of 6.5% by weight, as well as lesser amounts of phosphate and potassium. Because soybean meal contains 6.5% nitrogen by weight, it can also be used as fertilizer.

6. Crab Meal

Nitrogen Rich Organic Fertilizer

Chitin-rich soil amendments promote the growth of chitin-eating microorganisms. When the crab shells are gone, they morph into nematodes, which are rich in chitin. The nematode-limiting effect appears in 4-8 months, or sooner in warm soils with high N levels.

7. Mix Coffee Grounds In The Soil

Coffee grinds contain a lot of nitrogen. The grounds can either be mixed into the soil or added to your compost pile. Coffee grounds take time to break down and release into the soil, but they also help to aerate the ground and promote drainage.

8. Pant Nitrogen-Fixing Plants

Nitrogen Rich Organic Fertilizer

Certain plants are referred to be nitrogen-fixing plants, which implies that as they grow, they will contribute nitrogen to your soil. Beans and legumes are the two most important to include in your beds. They fix nutrients rather than taking nitrogen from the soil. Therefore think about planting beans and legumes where you grew nitrogen-hungry plants the year before.

One reason crop rotation is so important and should be planned out over several years due to this. Also, it’s crucial to remember that you should reduce or stop feeding the garden beds or locations where you had bean crops the previous year. There can be too much nitrogen in the soil as a result.
