Other claims from this paper (11)
- Observation Soil pH and available phosphorus content differed significantly by sampling site.
- Observation Phosphorus absorption coefficient varied markedly and significantly among sites.
- Observation AM fungal spore density differed markedly and significantly by soybean and maize sampling site.
- Association AM fungal spore density in soybean fields was negatively correlated with available phosphorus content.
- Association AM fungal spore density in soybean fields was positively correlated with phosphate adsorption.
- Mechanism The authors interpret higher available soil phosphorus from fertilizer as lowering AM fungal spore density.
- Association AM fungal spore density was generally higher in soils with higher phosphate absorption coefficient.
- Observation The authors consider this tendency marked in soils with a low phosphate adsorption coefficient.
- Association Soybean root infection ratio was positively correlated with AM fungal spore density.
- Association Soybean root infection ratio was negatively correlated with available phosphorus content.
- Recommendation The authors recommend avoiding excessive phosphorus fertilizer application.
