Biochar addition regulates soil phosphorus fractions and improves release of available phosphorus under freezing-thawing cycles.

Science of the Total Environment, 2022
Currently, the shortage of phosphorus resources is becoming more and more serious. In general, phosphorus fertilizer is poorly utilized in soil and tends to gradually accumulate.

Biochar phosphorus fertilizer effects on soil phosphorus availability

Chemosphere, 2020
Biochar is a potential material for making slow-releasing phosphorus (P) fertilizers for the sake of increasing soil P use efficiency and mitigating P losses. However, the long-term effects of P-laden biochars on soil P availability remains unconcerned.

Trichoderma strains accelerate maturation and increase available phosphorus during vermicomposting enriched with rock phosphate

Journal of Applied Microbiology, 2020
To suggest microbial inoculation as a tool to shorten organic residues stabilization and increase rock phosphate (RP) solubilization through vermicomposting, thus increasing nutrient content in plants and making it more appealing to farmers.

Availability of residual phosphorus in high phosphorus soils

Communications in Soil Science and Plant Analysis, 2002
Although we know soil phosphorus (P) can rapidly increase when fertilizer or manure is continually applied at rates exceeding crop removal, there is little information on the rate of P release from high P soils as a function of soil type. Surface samples (0–5 cm) were collected from five major soil types in Pennsylvania (Chester silt loam, Conotton ...

Phosphorus Availability from Phosphorus-Amended Water Treatment Residual

Communications in Soil Science and Plant Analysis, 2004
Abstract Water treatment residual (WTR) is a by-product generated from drinking water treatment facilities that often contains considerable amounts of aluminum (Al) or iron (Fe). Application of WTR to agricultural land can cause deficiencies in soil phosphorus (P).

Phosphorus: Ruminal Availability and Effects on Digestion

Journal of Animal Science, 1983
The availability of P for ruminal digestion in vivo from a mono-dicalcium phosphate containing 21% P (mono-dical), a mono-dicalcium phosphate containing 18.5% P (dical), and defluorinated rock phosphate was compared with sodium phosphate (Na2HPO4 X 7H2O). Mono-dical, dical and defluorinated rock phosphate were found to be 88, 62 and 40% as available as

Autoclaving Soil Samples Affects Algal‐Available Phosphorus

Journal of Environmental Quality, 2005
ABSTRACTUnwanted microbial interference in samples used for biological assays of P availability has routinely been eliminated by autoclaving samples before inoculation with algae. Twenty‐three soils were selected to evaluate the relationship between algal growth in P‐deficient solutions containing small quantities of soil and the level of P determined ...

Evaluation of available phosphorus in highly phosphorus-deficient soils

Plant and Soil, 1964
In a greenhouse experiment single superphosphate was supplied in varying rates to lettuce test plants grown in soils of very low phosphorus availability.

Phosphorus Source and Soil Properties Effects on Phosphorus Availability

Soil Science, 2011
Phosphorus (P) application in excess of crop needs has increased the concentration of P in soils and has been linked to freshwater eutrophication leading to P-based nutrient management. However, insufficient data are available relating soils properties, P-source solubility, and rate and time of application to develop sound guidelines. We investigated P
