The objective of this work was to determine the effect of sampling time and field heterogeneity on the soil fertility tests (pH, organic matter, N, P, K, Ca, Mg). The sampling on Ap horizons was repeated in May, July and October of 1976 at 25 locations of a clay loam soil (Kamouraska Series) and a sandy soil (Vien Series).

Analysis of available soil phosphate by isotopic dilution method, observed as kinetics between 1 and 100 min after the injection of 32PO43− in the soil–solution system, allows the measure of three kinetics parameters: r1/R, r1 is the radioactivity remaining in the solution after 1 min of isotopic exchange and R the total radioactivity injected in the ...

Pour remédier à la baisse de la fertilité des sols, les pratiques de gestion de la fertilité les plus performantes doivent être identifiées. L’objectif de cette étude est d’analyser les performances économiques de la production du maïs sous différents pratiques de gestion de la fertilité des sols au Nord du Bénin. Cette étude a été conduite
