That depends on what's meant by the word "available". In general, the nitrates are the quickest acting or most "available" to plants, however different species of plants can uptake different forms. Usually though, complex nitrogen compounds must be broken down to simpler compounds before plants can uptake them. Also, different formulations (of fertilizers) can change the way a plant uptakes nutrients. Usually, the quickest acting is a water soluble fertilizer (a powder that dissolves readily in water). Then, there are granular fertilizers that work a bit slower, and finally there are slow-release types that take weeks to months to release.
Nitrite is the form of nitrogen that is most readily usable by plants Plants need nitrogen for the synthesis of the peptide bonds in proteins.

What part of the nitrogen cycle is most responsible for making nitrogen available for plants?
The process of nitrogen fixation is most responsible for making nitrogen available for plants. This is when certain bacteria in the soil or in the roots of leguminous plants convert atmospheric nitrogen into a form that can be taken up by plants as nutrients.
How do most plants meet their nitrogen needs?
Most plants meet their nitrogen needs by absorbing nitrate and ammonium ions from the soil through their roots. Some plants also form symbiotic relationships with nitrogen-fixing bacteria, which convert atmospheric nitrogen into a form that plants can use. This process is important for plant growth and development.
Which forms of nitrogen are usefull to producers?
Producers primarily use nitrate (NO3-) and ammonium (NH4+) forms of nitrogen as they are readily available to plants and can be absorbed and utilized efficiently. Nitrate is the preferred form for most plants, while ammonium can be toxic if present in excess. Nitrogen-fixing bacteria can also convert atmospheric nitrogen into ammonium, making it available to plants in the soil.
Do plants take in nitrogen directly from the atmosphere?
Most plants cannot take in nitrogen directly from the atmosphere. Instead, they rely on nitrogen-fixing bacteria in the soil to convert atmospheric nitrogen into a form that plants can absorb, usually in the form of nitrate or ammonium. Leguminous plants, like peas and beans, have a symbiotic relationship with nitrogen-fixing bacteria in their root nodules.
Most crop plants acquire their nitrogen mainly in the form of?
Most crop plants acquire their nitrogen mainly in the form of nitrate and ammonium ions from soil. Plants take up nitrogen through their root systems where it can be used for protein synthesis and other essential processes. Nitrogen is a crucial nutrient for plant growth and development.

Even though considerable nitrogen is available in the air most plants do not use the nitrogen in the air why not?
Plants cannot directly use nitrogen gas (N2) from the air because they lack the enzymes required to convert N2 into a form (like ammonia or nitrates) that they can assimilate. Therefore, plants rely on nitrogen-fixing bacteria in the soil to convert atmospheric nitrogen into a usable form. This nitrogen fixation process allows plants to obtain the necessary nitrogen for growth and development.
Why is nitrogen a limiting nutrient?
This is because the particular form of nitrogen found in air “nitrogen gas“ cannot be assimilated by most organisms. For example, “Nitrogen nutrients are water-soluble and as a result they are easily drained away”, so that they are no longer available for plants.

In what form most organisms obtain nitrogen?
Most organisms obtain nitrogen in the form of nitrate (NO3-) or ammonium (NH4+). These forms of nitrogen are usually present in the soil and can be taken up by plants. Animals then obtain nitrogen by consuming plants or other animals.
Do plants take in nitrogen directly from the atmosphere?

Instead, they rely on nitrogen-fixing bacteria in the soil to convert atmospheric nitrogen into a form that plants can absorb, usually in the form of nitrate or ammonium. Leguminous plants, like peas and beans, have a symbiotic relationship with nitrogen-fixing bacteria in their root nodules.
What form must the nitrogen be in?
In order to be used by most plants, nitrogen must be in the form of nitrate (NO3-) or ammonium (NH4+). Plants cannot directly use atmospheric nitrogen (N2) as a nutrient source.
Most crop plants acquire their nitrogen mainly in the form of?
Most crop plants acquire their nitrogen mainly in the form of nitrate and ammonium ions from soil. Plants take up nitrogen through their root systems where it can be used for protein synthesis and other essential processes. Nitrogen is a crucial nutrient for plant growth and development.
Where do most plants get nitrogen from?
Most plants get nitrogen from the soil, where it exists in various forms such as nitrate, nitrite, and ammonium. Some plants, like legumes, also have a symbiotic relationship with nitrogen-fixing bacteria that convert atmospheric nitrogen into a form that plants can use. Nitrogen is a vital element for plant growth as it is a key component of proteins, enzymes, and chlorophyll.
What form must nitrogen take before plants and animals can use it?
Nitrogen must be in the form of ammonium (NH4+) or nitrate (NO3-) before plants and animals can use it for growth and development. These forms of nitrogen can be taken up by plant roots and further utilized in biological processes.
What is the most important fungi or bacteria for nitrogen fixation?
Rhizobium bacteria are the most important for nitrogen fixation in soil. They form a symbiotic relationship with leguminous plants, such as peas and beans, by forming nodules on their roots where they convert atmospheric nitrogen into a form that the plants can use.
