The effects of drip fertigation of NPK and vermicompost extract (VCE) on soil fertility
status of arecanut-only and arecanut-cocoa systems were assessed in a 4-year field
study. In arecanut, soil pH was reduced over initial levels. At 0–30 cm deep, fertigation
of 75 percent NPK to arecanut only and organic-matter recycling in arecanut + cocoa
maintained significantly greater soil organic carbon (SOC) and soil-test phosphorus
(P). At the first depth, soil potassium (K) was significantly greater with 75 percent NPK
(246 mg kg−1) than other treatments. In cocoa, soil pH varied significantly due to
fertigation at both depths. The SOC was reduced due to 75 percent NPK at the first
depth. In cocoa, the P availability increased significantly with application of VCE at 20
percent N. Fertigation of 75 percent NPK maintained significantly greater soil K and
soil Mg than other treatments. The results suggest that drip fertigation of NPK sustains
the soil fertility status in arecanut and cocoa.
