Decaying plant residues are not the only source of P in the soil. Manure and other organic residues (e.g., biosolids, composted manures, food waste residuals) contain phosphorus in plant available ...

When producers pay special attention to managing phosphorus (P), it can lead to profitable crop production. The best way to use fertilizers to meet P requirements changes with crop, soil properties ...

Soil pH is one of the most important factors influencing phosphorus management decisions. To determine the available phosphorus (P) of Minnesota plants, use the Bray-1 test when soil pH is 7.4 or less ...

Nitrogen (N) and phosphorus (P) are essential nutrients for all living organisms. Soil, fertilizer, and manure are all sources of N and P to growing crops. Atmospheric deposition (the air we breathe ...

An adequate supply of available P in soil is associated with increased root growth, which means roots can explore more soil for nutrients and moisture. Phosphorus occurs in most plants in ...

Researchers looking into effective ways of adding phosphorus (P) to increase soil fertility have saved organic farmers a lot of time and money. In a recent paper in the Canadian Journal of Soil ...

and on original approaches to better understand P speciation, bioavailability (inorganic and organic forms, different oxidation states) and biogeochemistry in a wide range of aquatic ecosystems.

For this reason, P use is most efficient when soil contact with fertilizer is limited, such as by banding. Phosphorus efficiency is greatest when applied with the seed, providing the amount does not ...

New Product of the Year runner-up RhizoSorb puts an emphasis on phosphorus sustainability from start to finish.

Successive applications of phosphate fertilisers can exceed the phosphorus (P) requirements of plants and soil, resulting in surface accumulation and loss to aquatic systems, and therefore require ...
