Soil organic P (Po) mineralization plays an important role in soil P cycling. Quantitative
information on the release of available inorganic P (Pi) by this process is difficult to obtain …

We studied the effect of an arbuscular mycorrhizal fungus (AMF), Glomus intraradices, on
the uptake of phosphorus (P) and zinc (Zn) by maize (Zea mays) in two types of …

Core Ideas More orthophosphate was found in extracts from soils managed conventionally.
More neo‐IHP was found in extracts from soils managed conventionally. Proportions of …

High levels of soil phosphorus (P), combined with the status of fertilizers and manures
applied, form what is called the source term in the critical source‐area (CSA) concept. This …

This chapter evaluates the consequences of practices used in organic farming on
phosphorus (P) balances at farm and field levels, soil inorganic P (Pi) availability for crops, P …

Use of isotope methods to measure the availability of phosphorus (P) in soils that are well
supplied with P is well established. We have evaluated such methods for acid tropical soils …

Fertilization should be based on a proper diagnosis of the plant nutritional status. Without,
there is always the risk of under fertilization causing economic losses by not exploiting the …

In the countries of the Baltic Sea Region (BSR) different extraction-methods are used to
assess plantavailable amounts of P in soils. Target of this knowledge report was the inter …

English To allow the comparison and interpretation of data obtained by different soil P tests,
different established extraction methods were investigated and statistically inter-calibrated …

Little information exists on the effect of land use management on isotopically exchangeable
phosphate (P) in agricultural soils of Burkina Faso. The 0–10 cm layer of 30 soils was …
