Relación del contenido de materia orgánica con el pH de los análisis de suelo en cinco provincias de Huánuco

Abstract: Los objetivos fueron (a) Evaluar el efecto del CIC (Capacidad de Intercambio Catiónico), pH, saturación de Ca+2 sobre la acidez cambiable en suelos de la región Huánuco, (b) determinar el efecto del CIC y arcilla sobre la MO (materia orgánica) total y, (c) medir el efecto de la MO total pH sobre la acidez cambiable y pH. Se estudiaron 130 suelos agrícolas de cinco provincias de la región Huánuco: Huánuco, Pachitea, Ambo, Yarowilca, Huamalíes. Los datos se colectaron de los trabajos de investigación realizados … Show more

“…Additionally, the nitrogen content was higher in soils under ‘chiwa’ soils due to the possibility that residue decomposition could contribute significant amounts of N to the soil 20 . Furthermore, we registered that both traditional tillage systems had acidic soils which may reflect an inadequate use of fertilizers in the potato cultivation 24 , or the geological origins of these soils 25 , or soil leaching as a result of irrigation or rainfall 26 . On the other hand, the phosphorus content was similar between the systems; however, these soils can be classified as low-phosphorus soils, which is typical of acidic soils where the mineralization of phosphorus is limited 27 .…”
