Anhydrous ammonia is generally the cheapest source of N; however, the method of application is less convenient and requires more power than other forms. Nitrogen solutions are a mixture of urea and ammonium nitrate in water, providing 28 to 32 percent N content. These solutions offer a convenient alternative to anhydrous ammonia, with easier application and handling, although they may be slightly more expensive. When considering nitrogen fertilizer options, it is essential to balance cost-effectiveness with practicality and efficiency in application methods.

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.
Are cucumbers nitrogen-fixing?
Cucumbers do not fix nitrogen. However, other legumes like peanuts, cowpeas, soybeans, and fava beans are efficient nitrogen fixers. These crops can fix all the nitrogen they need, up to 250 lb per acre, without requiring additional fertilization. This information is supported by studies conducted by Walley et al. in 1996 and Cash et al. in 1981.
What is the best cheap nitrogen fertilizer?
The best affordable nitrogen fertilizer solution is nitrogen-fixing plants. These plants host rhizobia bacteria on their roots, which transform atmospheric nitrogen into usable nitrogen compounds for their growth. This makes them a cost-effective and efficient option for enriching soil with nitrogen. Other alternatives to consider for inexpensive nitrogen fertilization include:
1. Alfalfa meal
2. Feather meal
3. Blood meal

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).
What are the most common nitrogen fixers?
Common nitrogen fixers include leguminous plants such as peanuts, peas, and beans, which form a symbiotic relationship with rhizobium bacteria to add nitrogen to the soil. Peanuts specifically develop a structure called a peg after pollination, extending into the soil for growth. Harvesting occurs when the peanut plant’s leaves begin to yellow at the end of the growing season. Treating seeds with rhizobium bacteria before planting enhances nitrogen fixation.
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.
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.
Do sugar peas fix nitrogen?
