Today we take a leaf sampling unit (LSU) of plam oil. Before we take a LSU we have already make a mark sign at the palm oil for sampling. The plant sample must be representative from the whole areal. It must be healthy, far from the street and good production. We take a sample at the 17nd leaf. We demonstrate to the foreman/mandor before the get started. The functional of LSU are that we can know the condition of nutrition of our plant and we can know the fertilizer we need. This LSU we send to iopri/ppks the get the result.
