Fertilisation et gradients de potassium dans des sols en pente au Maroc
Résumé
In slope soils, exchangeable K levels vary depending on the distance between the measurement location and the bottom of the slope. To avoid the need of measuring K content throughout the slope, an experimental relation is proposed to estimate K content anywhere on the slope when bottom values are known. Another relation is proposed to estimate clay content, which also varies along the slope gradient. In conclusion, determination of potential K dressings for slope soils is discussed.Téléchargements
