If you are using for Nitrogen fixation we highly recommend using a cowpea inoculant. The Elite cowpea is a bush type cream southern pea that produces heavy yields of 7″ pods with cowpeas that are delicious and easy to shell. This cowpea is one of the most productive of all the cream peas.

Do beans and peas fix nitrogen?

Yes, beans and peas fix nitrogen. Legumes like beans, peas, and clovers have a symbiotic relationship with soil bacteria. This relationship enables them to convert atmospheric nitrogen (N2) into ammonium nitrogen (NH4), which enriches the soil.

Additional information:
1. Nitrogen fixation by legumes reduces the need for synthetic fertilizers.
2. The process helps improve soil fertility and productivity.
3. Legumes are commonly used in crop rotation to enhance soil health.
4. Nitrogen-fixing plants play a crucial role in sustainable agriculture practices.

Do pea plants fix nitrogen?

Yes, pea plants fix nitrogen. Legume crops like peas, beans, peanuts, and soy are able to fix nitrogen from the air. They thrive in nitrogen-deficient soils with the aid of Rhizobium bacteria, which promote the formation of nodules on the plants’ roots. This symbiotic relationship helps the leguminous plants to access and utilize nitrogen for their growth and development.

What beans are good for nitrogen-fixing?

Other grain legumes like peanuts, cowpeas, soybeans, and fava beans are excellent for nitrogen-fixing. They can fix up to 250 lb of nitrogen per acre, meeting their nitrogen requirements, except for what they absorb from the soil (Walley et al., 1996; Cash et al., 1981). These legumes generally do not require fertilization.

What is a nitrogen-fixing plant?


A nitrogen-fixing plant is a type of plant, such as legumes, that has a symbiotic relationship with soil bacteria. This relationship enables these plants to convert atmospheric nitrogen (N2) into a usable form, ammonium nitrogen (NH4), which enriches the soil.

1. Legumes, including beans, peas, and clovers, are common examples of nitrogen-fixing plants.
2. They work in partnership with soil bacteria to transform atmospheric nitrogen into a form that can be absorbed by plants.
3. The ammonium nitrogen produced by these plants benefits the soil by enriching its nutrient content.
4. This process plays a crucial role in natural ecosystem balance and agricultural sustainability.

Which legume doesn t fix nitrogen?

Which legume does not fix nitrogen?
Legume plants like peas, beans, and clover are known for their ability to fix nitrogen from the air with the help of symbiotic bacteria in their roots. However, one legume that does not fix nitrogen is the peanut. Peanuts have a shallow root system that limits their ability to form nodules with nitrogen-fixing bacteria, making them dependent on nitrogen in the soil for their growth.

Do nitrogen-fixing plants add nitrogen to soil?

Yes, nitrogen-fixing plants like peanuts, cowpeas, soybeans, and fava beans add nitrogen to the soil. These plants can fix up to 250 lb of nitrogen per acre by utilizing this process, making them self-sufficient in terms of nitrogen needs. They are efficient in enhancing soil fertility without the requirement for additional fertilization practices, as supported by studies (Walley et al., 1996; Cash et al., 1981).

The Unfortunate Truth About Nitrogen Fixing Plants

Do sugar peas fix nitrogen?

Yes, sugar peas fix nitrogen. Alfalfa (Medicago sativa) is recognized as one of the most potent nitrogen fixers within the legume family. It can fix between 250-500 pounds of nitrogen per acre. Additionally, alfalfa is rich in iron, phosphorus, potassium, magnesium, and various trace minerals, making it beneficial for enhancing soil fertility and crop growth. Moreover, it can improve crop rotation systems and reduce the need for synthetic fertilizers.

Do all beans fix nitrogen?

Not all beans fix nitrogen. Many heterotrophic bacteria in the soil can fix nitrogen independently. Some examples of such nitrogen-fixing bacteria are Azotobacter, Bacillus, Clostridium, and Klebsiella.

1. Not all legumes have a symbiotic relationship with nitrogen-fixing bacteria.
2. Some legumes, like soybeans and alfalfa, have nodules containing Rhizobium bacteria for nitrogen fixation.
3. Other legumes, such as peanuts and chickpeas, can fix atmospheric nitrogen without the help of symbiotic bacteria.
4. Legumes like lentils and beans may not have as high nitrogen-fixing capabilities as other legumes.

Do peanuts add nitrogen to soil?

Do peanuts contribute nitrogen to soil? Peanuts primarily absorb nitrogen during their growth stages, with developing roots and leaves being the main nitrogen sinks during vegetative phases, and flowers, fruits, and seeds serving as the major nitrogen-consuming sinks in the reproductive stage (Masclaux-Daubresse et al., 2010).

1. Peanuts absorb nitrogen mainly during growth stages.
2. Developing roots and leaves are primary nitrogen sinks in vegetative phases.
3. Flowers, fruits, and seeds are major nitrogen-consuming sinks in reproductive stages.

What legumes fix nitrogen?

Legume crops such as beans, peanuts, and soy fix nitrogen from the air, thriving in nitrogen-deficient soils with the assistance of Rhizobium bacteria. These bacteria induce the formation of nodules on the roots of leguminous plants, enhancing nitrogen fixation. This symbiotic relationship enables legumes to pull nitrogen from the atmosphere and improve soil fertility.

Which is the fastest nitrogen fixing plant?


The fastest nitrogen fixing plant is alfalfa (Medicago sativa). It is one of the most potent nitrogen fixers among legumes, capable of fixing 250–500 lb of nitrogen per acre. Alfalfa is rich in iron and provides significant amounts of phosphorus, potassium, magnesium, and trace minerals. This makes it a valuable crop for improving soil fertility and health.

Is corn a nitrogen fixer?

Yes, corn is a nitrogen fixer because it has rhizobia bacteria on its roots that convert atmospheric nitrogen into nitrogen compounds for the plant’s benefit.

1. Corn is considered a moderate nitrogen fixer compared to legumes like soybeans and clover.
2. The presence of rhizobia bacteria on corn roots helps improve soil fertility by fixing nitrogen.
3. Growing corn in a crop rotation system can contribute to sustainable agricultural practices by reducing the need for synthetic nitrogen fertilizers.

Do dandelions fix nitrogen?

Yes, dandelions are capable of fixing nitrogen. Alfalfa, known scientifically as Medicago sativa, is a proficient nitrogen fixer among legumes and can fix between 250-500 pounds of nitrogen per acre. Additionally, alfalfa is rich in iron and serves as a good source of phosphorus, potassium, magnesium, and essential trace minerals for plant growth.

What plant fertilizer has the most nitrogen?

The plant fertilizer with the highest nitrogen content is commonly found in legumes. While certain legumes excel in fixing nitrogen, others like common beans are less effective with a nitrogen-fixing capacity of less than 50 lb N per acre. To optimize bean production in New Mexico, an additional 30-50 lb of fertilizer nitrogen per acre is needed to achieve the maximum economic yield.

Do sweet peas add nitrogen to soil?

Yes, sweet peas can add nitrogen to the soil. Other legumes like peanuts, cowpeas, soybeans, and fava beans are known to fix nitrogen efficiently, meeting most of their needs without additional fertilization. These legumes can fix up to 250 lbs of nitrogen per acre and are often not fertilized (Walley et al., 1996; Cash et al., 1981). This natural nitrogen-fixing process can benefit the soil’s health and fertility over time.

Do all peas fix nitrogen?

But legumes, including yellow peas, provide another way. Legumes have built-in nitrogen “fixers.” Most pea plants flourish in symbiotic relationship with rhizobia, bacteria that live in nodules in the legumes’ roots.

In conclusion, peas are excellent nitrogen-fixing plants that can benefit both the soil and surrounding vegetation. When choosing the best peas for nitrogen-fixing, consider factors such as climate, soil conditions, and intended use. Whether you opt for garden peas, snow peas, or snap peas, incorporating these legumes into your crop rotation or garden can contribute to improved soil fertility and sustainability. Experimenting with different pea varieties can help you find the ones that work best for your specific needs, ultimately leading to healthier plants and a more productive garden. So, explore your options and start reaping the benefits of nitrogen-fixing peas today!
