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 …

We studied microbiological processes in organic P transformations in soils cultivated with
conventional and biological farming systems during the 13th and 14th year of different …

Lower P‐input levels in organic than conventional farming can decrease soil total and
available P, which can potentially be resupplied from soil organic P. We studied the effect of …

Today on many sites organic farming might neglect phosphorus (P) fertilization due to soil
reserves build up by P fertilization of former farming systems. Additionally organic farming …

Phosphorus (P) is a major nutrient for all living organisms and a key production factor in
agriculture. In crop production, it is usually supplied to soils through fertilisers or recycled …

Phosphorus deficiency is wide-spread due to the poor solubility of soil P and the rapid
formation of poorly available P after P addition. Microbes play a key role in soil P dynamics …

There is a lack in knowledge about microbially mediated phosphorus (P) transformation
processesin soils. In this thesis, existing isotopictechniquesfor measuringP0 mineralisation …

The aim of this work was to assess to which extent organic farming practices would affect the
accumulation of total and available phosphorus (P) in a cropped soil in comparison to …

A number of organic farms in Flanders were sampled to investigate the general phosphorus
(P) status and degree of P saturation (Psat) of the soils. Where possible, the soil P status …

Phosphorus (P) is an essential plant nutrient that needs to be managed carefully in organic
systems so that crop yield and quality remain sustainable without contributing to …
