Sustainable Oil Palm Farming / Applying boron (B)
Download: Module 4: Fertiliser Application
- Provide oil palms with sufficient boron to produce optimum yields;
- Limit the loss of boron to the environment.
Boron fertiliser is applied according to the 4R principle: right type, right amount, right place, right time.
Not during very wet periods.
Once per year.
Labour time required
2—4 hours per hectare.
Equipment and materials
- Bucket, bag or wheelbarrow
- Kitchen scales
- Black marker pen
- Cup or small bowl
Farmers and their families or hired labourers.
Boron fertiliser is applied in small quantities and is toxic when applied in too large amounts.
Apply boron fertiliser by following these steps:
|Step 1.||Before application, remove all weeds from the weeded circle.|
|Step 2.||Weigh the amount to be applied in a bowl or cup, using kitchen scales.|
|Step 3.||Mark the bowl / cup at the right amount using a black marker pen.|
|Step 4.||Break any clumps into small pieces before application of fertiliser.|
|Step 5.||Apply boron fertiliser evenly in the weeded circle for palms of all ages.|
Note: Boron fertiliser is mildly toxic, so it is best not to eat, drink or smoke during application and to wash hands immediately after application.
Every fertiliser application should be recorded in a logbook as shown in the example below.
