Biomass estimations and carbon stock calculations in the oil palm plantations of African derived savannas using IKONOS data
This study developed biomass models to calculate carbon stock levels of the West African oil palms (Elaeis guineensis) using multi-date wet and dry season IKONOS images. Two benchmark areas of theExpand

Assessing the effect of soil tillage on crop growth: A meta-regression analysis on European crop yields under conservation agriculture
Abstract Many strategies exist to combat soil degradation through erosion and compaction on agricultural fields. One of these strategies is conservation agriculture (CA). Reduced or no-tillageExpand

Maize Yield as Affected by Organic Inputs and Urea in the West African Moist Savanna
Nutrient depletion is a major constraint to crop production for moist savanna soils, and inputs of nutrients are required to overcome this constraint. The impact of sole and combined applications ofExpand

Long-term soil organic carbon dynamics in a subhumid tropical climate: 13C data in mixed C3/C4 cropping and modeling with ROTHC
Abstract Scanty information on long-term soil organic carbon (SOC) dynamics hampers validation of SOC models in the tropics. We observed SOC content changes in a 16-year continuously croppedExpand

Integrated Plant Nutrient Management in Sub-Saharan Africa: From Concept to Practice
Soil degradation and nutrient depletion have become serious threats to agricultural productivity in Africa. Soils cannot supply the quantities of nutrients required and yield levels decline rapidlyExpand

A comparison of the contributions of clay, silt, and organic matter to the effective CEC of soils of subSaharan Africa
The contributions of clay, silt, and organic matter (OM) to the effective cation exchange capacity (ECEC) of soils in subSaharan Africa were examined using data from more than 2131 soil samplesExpand

Assessment of labile phosphorus fractions and adsorption characteristics in relation to soil properties of West African savanna soils
Abstract A large proportion of total P in the soils of the area is unavailable to plants and consequently P is the second most limiting nutrient. The labile and moderately labile phosphorus fractionsExpand

Phosphorus losses from agricultural land to natural waters are reduced by immobilization in iron-rich sediments of drainage ditches.
Redox reactions involving iron (Fe) strongly affect the mobility of phosphorus (P) and its migration from agricultural land to freshwater. We studied the transfer of P from groundwater to openExpand
