What is phosphates or phosphites?
A phosphate phosphite is a chemical compound or salt that contains phosphate and phosphite anions (PO33- and PO43-). These are mixed anion compounds or mixed valence compounds. In these phosphate and phosphite form bridging ligands to hard metal ions.
What is the difference between phosphate and phosphonate?
Phosphonate fungicides and fertilizers are absorbed by plants and incorporated into cells as phosphite ions (H2PO3-). The fact that this ion has one less oxygen atom than phosphate means that it does not act in the same manner as phosphate in plants.
What is the difference in molecular formula between phosphate and phosphite?
Biologically, the fundamental differences between phosphate and phosphite are vast. The difference in molecular structure between phosphate and phosphite means that phosphite cannot substitute for phosphate in the essential biochemistry of life. Phosphite molecules have bond angles of 107 degrees.
Is phosphorus and phosphate fertilizer the same?
There should be no difference in P fertilizer sources, as long as nutrient analysis differences are taken into account. While there are certain situations where one product performs better, phosphorus fertilizer recommendations are the same regardless of the phosphate fertilizer source.
What is phosphonate used for?
3.3. 5. Phosphonates. Phosphonates are strong complexing agents used in bleach-containing detergents for the stabilization of the active by preventing its catalytic decomposition due to heavy metal traces.
Why is the phosphonate so acidic?
the phosphonate is deprotonated with a relatively weak base, sodium methoxide. Why is the phosphonate so acidic? Phosphonate has multiple oxygen atoms, which are electron withdrawing. In addition to this, the double bond between Phosphorus and oxygen allows for resonance structures, creating an even stronger acid.
Is phosphite and phosphate the same?
In context|chemistry|lang=en terms the difference between phosphate and phosphite. is that phosphate is (chemistry) any salt or ester of phosphoric acid while phosphite is (chemistry) the anion po33-, or the trivalent radical po3.
What natural fertilizer is high in phosphorus?
Bone meal is an excellent high-phosphorus fertilizer with an average N-P-K ratio of 3-15-0. The phosphorous in bone meal takes a few months to become available to plants via microbial processes in the soil. It also contains calcium, another essential plant nutrient.
Why is it phosphate instead of phosphide?
In context|chemistry|lang=en terms the difference between phosphate and phosphide. is that phosphate is (chemistry) any salt or ester of phosphoric acid while phosphide is (chemistry) any binary compound of phosphorus, especially one in oxidation state −3.
Can phosponates replace phosphorus fertilizers?
Results of studies conducted in both countries demonstrated that phosponates were not effective substitutes for phosphate fertilizer. Scientists found that yields of legumes and grasses treated with calcium phosphite were lower than phosphate-treated plants, and in most cases, lower than controls plants receiving no phosphorus.
How is Phosphite used in photosynthesis?
Although the phosphite ion can be transported into plant cells, it does not appear to be involved in any phase of phosphorus metabolism (ATP production, photosynthesis, or respiration). Over time, phosphonate fertilizer can be converted by bacteria to phosphate in soil, where it can be taken up and metabolized by plants.
What is the difference between phosphonate fertilizers and fungicides?
Phosphonate fungicides and fertilizers should not be confused with phosphate-derived fertilizers such as ammonium phosphate and triple super phosphate. Even though phosphonate and phosphate compounds are very similar chemically, they differ significantly in how they act in plants and fungi.
Does calcium phosphite affect plant yields?
Scientists found that yields of legumes and grasses treated with calcium phosphite were lower than phosphate-treated plants, and in most cases, lower than controls plants receiving no phosphorus. However, a second crop seeded into the same soils that were treated with calcium phosphite showed improved yields.
