Fertilizer Schedule for Coffee
Generally, the advisory on fertilizer application is given based on soil test values.
If the soil testing is not done so far, it is advised to collect the soil sample (block wise) and send it to Coffee Research Sub Stations.
Based on the soil test values, the quantities of fertilizer required to be applied block-wise will be given for the next 3 years.
Application of Sulphur during post monsoon time is very important as Sulphur plays a key role in flower bud initiation.
