WebNitrogen (N) makes up approximately 79% of the atmosphere. Even though there is an abundance of Nitrogen in the atmosphere, plants’ ability to take advantage of this is very limited. Atmospheric Nitrogen is only readily available to a couple of plant species with the assistance of symbiotically associated N-fixing microbes. WebApr 3, 2024 · The forms of phosphorus most readily accessed by plants are orthophosphate ions (H 2 PO 4–, HPO 42-) whose availability depends on soil pH. Application of chemical fertilizer temporarily increases the concentration of the plant-available phosphorus pool in soil and supports the plant phosphorus needs during their vegetative and reproductive …

WebNitrogen is Not Readily Available But these are only a few advantages that don’t matter significantly. And the reason we are saying that nitrogen is not readily available everywhere like regular air. Even the stores like Costco only provide regular nitrogen inflation services for new nitrogen tire owners, not the existing ones. Manure in storage facilities typically lacks free oxygen. High rates of biological activity in liquid storages, dry manure stacks, and compost piles exceed the rate of oxygen supply creating anaerobic conditions. Under these conditions all mineral nitrogen in the storage is converted to the ammonium form … See more Most commercial nitrogen fertilizers are 100 percent plant available when applied to the soil.
