Phosphorus Liberator

Phosphorus Liberator is a soil-applied product that dissolves existing phosphorus locked up in the soil, making it available to plants and improving soil health.

Phosphorus Liberator contains carboxylic acid salt – an organic compound with the ability to break down calcium phosphate found in soil, into crop available form.

By using organic acid complexes, bound calcium phosphate is released in a manner that is not possible with water alone, and is neutralised with a counter-ion that allows the freed calcium phosphate to stay in solution.

By keeping phosphate in solution, the bonds with other minerals such as calcium are broken. Once broken down, phosphate is then available in the soil for uptake by the plant as nutrition.

Phosphorus is critical for crop growth, particularly during important phases such as germination, rooting, flowering and seed production. Deficiency of this important mineral can lead to reduced growth, tillering and tuberisation, and necrosis of older leaves.

The carboxylic acid technology found in Phosphorus Liberator also releases soil-bound manganese, whilst feeding saprotrophic fungi – organisms that help to degrade organic matter and release other nutrients found in soil.

With potential restrictions to phosphorus management on the horizon, effectively utilising existing soil-bound nutrients and improving water quality will be pivotal.

Phosphorus Liberator offers the following benefits:

  • Improves soil heath and access to nutrition
  • Supports plant growth and establishment through increased rooting
  • Maximises phosphate and fertiliser efficiency

Phosphorus Liberator trials 

Agrovista trials conducted autumn 2019 at a site in Leominster show a visible improvement in the establishment of oilseed rape following an application of Phosphorus Liberator at 5l/ha.

Images show 10 days post application.

Phosphorus Liberator also performs well during difficult oilseed rape establishment conditions, such as this high-trash site in north Yorkshire.

 

Winter wheat early crop assessment, Suffolk 2020

A winter wheat crop assessment conducted in Suffolk in January 2020 shows the positive impact Phosphorus Liberator can have on average plant and root weight.

Spring bean development, Oxford 2020

An assessment on spring beans in Oxford 2020 also shows favourable results.
