Integrated Soil Fertility Management (ISFM) on Coconut + Lanzones (Lansium domesticum Corr) Agro-ecosystem in Southern Mindanao, Philippines (1993 - 2007): with Emphasis on the Multi-nutrient Coconut-Specific Mineral Fertilizer*. Part I. Crop Productivity, Quality and Profitability

摘要

A 15-year (1993-2007) integrated soil fertility management (ISFM) of coconut + lanzones fruit agro-ecosystem was conducted using five fertilizer combinations (PCs) in a dominantly tropical wet climate (Koppen-Geiger Climate Classification Kottek et al2006) of Davao, Southern Mindanao (07°05'N 125°37'E), It aimed to determine the response of this agro-ecosystem to the combined multi-nutrient fertilizer N+P+K+C1+S+B (14-5-20-0.02B-15.5C1-4.5S) and organic fertilizer (OF) sources at different ratios
