Tujuan

  • Memberi kelapa sawit asupan potasium yang cukup untuk menghasilkan hasil panen yang optimal;
  • Membatasi hilangnya unsur potasium dari lingkungan.

Standarisasi

Pupuk potasium diaplikasikan menurut prinsip 4R: right type (jenis yang tepat), right amount (jumlah yang tepat), right place (lokasi yang tepat), right time (waktu yang tepat).

Waktu pelaksanaan

Tidak pada saat puncak musim hujan.

Frekuensi

  • Pada semua jenis tanah: 2--3 dosis per tahun (sekali dalam 4-6 bulan);
  • Pada tanah berpasir dan tanah gambut: 3-4 dosis per tahun (sekali dalam 3-4 bulan).

Kebutuhan waktu tenaga kerja

2-4 jam per hektar.

Peralatan dan perlengkapan

  • Ember, kantong atau
  • Timbangan dapur
  • Spidol hitam
  • Mangkuk (ukuran 1.5 – 2 L)
  • Pupuk

Dosis

See: Table 4; Table 5; Table 6; Table 7.

Who

Farmers and their families or hired labourers.

How

Apply potassium fertiliser by following these steps:

Step 1. Before application, remove noxious weeds and slash ground cover to 50 cm height.
Step 2. Weigh the amount of fertiliser 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 up any fertiliser clumps into small pieces before application (see Figure 21).
Step 5. Apply the fertiliser in the following way:
  • For palms younger than 7 years after planting, K should be applied evenly in the weeded circle;
  • For palms 7—10 years after planting, K should be applied in a band around the weeded circle;
  • For palms greater than 10 years after planting, K should be broadcast over the frond stack and in the inter-row, apart from the harvesting path;
  • Apply bunch ash in the weeded circle 1.

If palms are on the edge of a river, road or ditch, avoid applying fertilisers on the side of the palm closest to the edge (if fertiliser is being broadcast).

Data recording

Every fertiliser application should be recorded in a log book as shown in the example below.

Date Time Location Activity Input type Input amount Input costs Labour input Labour costs
