(No Panacea for Poor Tropical West African Soils and Expensive Fertilizers)22 Options for Soil Organic Carbon Maintenance under Intensive Cropping in the West African Savannah; 23 On-farm Research and Operational Strategies in Soil Fertility Management; 24 Recommendations; Index | |
Sommario/riassunto: | 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 rapidly once cropping commences. This book addresses these issues. |
