Abstract
|
|
|
|
Available phosphorus(P2O5) in conventionally cultivated soil was more abundant in two fold than that of organically cultivated soil. Relative density of Arbuscular Mycorrhizal Fungi (AMF) was higher in organically cultivated soil, That of welsh onion cultivated soil was the highest, that of strawberry was followed and then that of pepper, respectively. Relative density of AMF was inversely proportioned to available soil phosphorus. Phosphorus content of crop and relative density of AMF were more abundant in organically cultivated crop or soil. However available soil phosphorus content was much in conventionally cultivated soil. The phosphorus contents between soil and crop were negatively correlated. The phosphorus content of crop was increased as the relative density of AMF increased. Relative density of AMF in the organically cultivated soil and phosphorus content of the crop with organic cultivation were higher than those of conventionally cultivated.
