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.
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.
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.
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.
Plants that can use nitrogen from the atmosphere are known as nitrogen fixers. The legume or pea family of plants are famous for being able to do this.Most plants don't have this ability.
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.

The most usable form of nitrogen for plants is nitrate (NO3-).
Plants most easily use nitrate form of nitrogen. They can also use ammonium form, but nitrate is preferred because it is more readily available in soil and easier for plants to absorb.
Plants most easily use nitrate (NO3-) as the form of nitrogen for their growth and development.
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.
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.

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.
