Phosphorus management issues for crop production: A review

July, 2021

Phosphorus (P) is an essential element for plant growth. On account of its low solubility in soil, P is often a limiting factor to optimum crop growth and therefore P fertilisation is an important aspect of nutrient management plans to ensure profitable and sustainable crop production. Plant P availability is controlled by sorption, desorption and precipitation of P from P released during weathering of P minerals and...

This study aimed to study physicochemical and microbiological parameters during nonnonkoumou production. A total of 15 samples were analyzed during this study at a rate of 3 samples per fermentation time (T0 h, T6 h, T12 h, T18 h and T24 h). The physicochemical analyses showed a drop in pH (from 7.03 ± 0.028 to 4.59 ± 0.021) during the 24 h of fermentation. The titratable acidity increased from 0.30...
