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.

Availability of Phosphorus in Nilgiri Soils

Madras Agricultural Journal, 1967
Availability of phosphorus in soils is one of the factors affecting crop production. In acid soils, though total phosphorus is high, its availability is very low due to adverse environmental and resulting pedogenic factors. An attempt was made therefore, to assess the phosphorus availability in soils of Nilgiris, and to study the effect of rainfall ...

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 ...

Biological and Chemical Determination of Available Phosphorus in Soil

Zentralblatt für Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene. Zweite Naturwissenschaftliche Abteilung: Allgemeine, Landwirtschaftliche und Technische Mikrobiologie, 1973
Summary A study for correlating some biological and chemical methods to determine available phosphorus as affected by some soil properties was carried out, using 30 Egyptian soil samples. The Aspergillus method appeared to be superior in the quantities of phosphorus extracted from soil, followed by the Olsen and then the Egner method.
