Which fertilizer is most effective for plant growth?
Most gardeners should use a complete fertilizer with twice as much phosphorus as nitrogen or potassium. An example would be 10-20-10 or 12-24-12. These fertilizers usually are easy to find. Some soils contain enough potassium for good plant growth and don’t need more.
How does phosphite help plants?
Phosphite (Phi) is emerging as a novel plant biostimulator. Phosphite has been shown to improve crop yield and quality, as well as stimulate environmental stress responses in horticultural crops. Phi has not been proved to have a direct effect on plant nutrition, and should not be considered as a proper fertilizer.
What is the difference between phosphate and phosphonate?
Phosphonates are generally capable of offering the same level of scale control as phosphates but can be included in formulations at concentrations one order of magnitude lower than phosphates. Although not readily biodegradable, phosphonates are not immune to photodegradation, hydrolysis or biodegradation over time.

How do you make potassium phosphite?
The most common phosphite is potassium phosphite, and is made by mixing a solution of potassium hydroxide with phosphonic acid. Potassium phosphite is also referred to as mono- and di-potassium salts of phosphorous acid on some phosphonate product labels.
Why is 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.
Why are phosphates in fertilizer?
The function of phosphorus in plants is very important. It helps a plant convert other nutrients into usable building blocks with which to grow. Phosphorus is one of the main three nutrients most commonly found in fertilizers and is the “P” in the NPK balance that is listed on fertilizers.
When to apply super phosphate to a garden?
When to Apply Super Phosphate to a Garden Soil pH Levels Affect Phosphorous Availability. Soil pH levels affect the availability of phosphorous for plant use, with the greatest availability when soil pH is between 6.5 and 7.0. Super Phosphate Mixed into Soil. Banding Super Phosphate Benefits Plants. Super Phosphate for Established Plants.
What is high P fertilizer?
High-phosphorus fertilizers help boost root development and increase a plant’s productivity. This type of fertilizer is especially useful when starting new plants, trees and lawns.
What is low phosphorus fertilizer?
Fertilizing with a low phosphorus fertilizer has advantages, but it is possible to go too far and provide insufficient levels of phosphorus, which stops plant growth. When using low phosphorus fertilizers, it is best to monitor the phosphorus levels in the growing medium and plant tissue to minimize deficiencies.
