1. Assessment of Performance of APSIM Model with Experimental Data from the Short-term Biochar Experiment at Guinea Savanna Zone (Nyankpala), Ghana

A three-year season, short-term study (2017–2019) was conducted at farming for the future UDS-Nyankpala, near Tamale in the Guinea Savannah Zone of Ghana. It was done to assess the effect of five different sources of biochar applications on rice-cowpea intercrop system on soil nutrient status and upland rice productivity. The experimental treatments comprised a control, 5 t/ha rates of high and low pyrolysis (400-7000C) of biochar. Five different sources of biochar (groundnut...

2. Integrating Models and Data to Observe the Effect of Biochar Used in a Rice-Cowpea Intercrop System on Soil Hydrological Properties

Physical properties of biochar like small particle size are highly porous and can modify soil properties and help to enhance soil water dynamics. However, there has been no consistent long-term measurements of change in soil physical properties due to biochar application under real field conditions. The objective was to assess the impact of biochar use in a rice-cowpea intercrop system on soil hydraulic properties at the field by integrating a modeling with soil water content measurements in two...

3. Simulate Plant Growth Response to Biochar applications on upland rice-cowpea intercrop and Inorganic N and P on a Ferric luvisols Soil in Ghana

Five different sources of biochar (groundnut shells, rice husk, poultry manure, sawdust, and corn cobs) at a rate of 5t/ha were incorporated into the soil at a depth of 30 cm during field experiments in Nyankpala in Ghana. A split plot factorial design arranged in a randomized complete block with 4 replications was used. The uniqueness of the studies was that cowpea and inorganic fertilizer treatments were added to aid upland rice-cowpea N and P content of the biochar. These studies provide a...

4. Does the combination of conservation agriculture and fertilizer microdosing improve soil chemical properties in semi-arid Zimbabwe in the short term?

Crop yields in the fragile semi-arid areas of Zimbabwe have been declining over time due to decline in soil fertility resulting mainly from droughts and lack of fertilizers. However, conservation agriculture (CA) and fertilizer micro-dosing (MD) have the potential to sustainably improve crop yields. A field experiment was set-up to assess the effects of integrating CA and MD on soil quality. It was hypothesized that the two practices improve soil chemical properties (soil organic carbon (SOC),... A. Shumba

5. Les engrais minéraux issus du diagnostic sol améliorent la fertilité chimique et la production cacaoyère à l’Est, au Centre-Sud et au Sud-Ouest de la Côte d’Ivoire

Une étude sur la fertilisation minérale raisonnée a été faite sur trois ans, à l’Est (Indénié-Djuablin), au Centre-Sud (Lôh-Djiboua) et au Sud-Ouest (Nawa) de la Côte d’Ivoire afin, d’évaluer les effets de 6 formules d’engrais minéraux sur la fertilité du sol et la production cacaoyère. Ainsi, sur chaque site, le dispositif expérimental a été en bloc de Fisher,... A. Kotaix
