Arbuscular mycorrhizal fungi biofertilization improves Cyperus esculentus growth, yield, and nutrient uptake while restoring degraded Paleudults in Southeastern Nigeria
Degraded Typic Paleudults in Southeastern Nigeria are characterised by strong acidity, severe phosphorus fixation, low organic matter, and depleted cation exchange capacity—conditions that severely constrain tigernut ( Cyperus esculentus L.) productivity and drive unsustainable mineral fertilizer dependence in...
