In this study, soil organic P (Po) and low-molecular-weight organic acids (LMWOAs) were quantified under different land uses in order to investigate the effect of N2 fixing tree introduction on phosphorus cycle. Soils were collected from plantations

Publikováno v: Geoderma

A better understanding of the composition of organic phosphorus (organic P) and low-molecular-weight organic acids (LMWOAs) in soil will make it possible to predict phosphorus cycling, improve biomass production and help phosphorus management in fore

Eucalypts, fast-growing trees, are planted in nutrient-poor soils such as sandy savannas in Congo, and deplete highly soil macronutrients such as N and P. To increase N inputs, the N-fixing tree species acacia was intercropped in eucalypt plantations

14. Rencontres Hélio-SPIR: Spectrométrie proche infrarouge et hétérogénéité, Nov 2013, Montpellier, France

La validation des méthodes et l’évaluation de l’incertitude sont deux exigences de la norme ISO 17025. L’utilisation de la spectroscopie proche infrarouge à des fins d’analyse quantitative nécessite par conséquent l’estimation de la ju
