Establishment
Emergence through early rootingUniform stand, fine roots, modest fertility
Help Sweet Potato establish uniformly in loose soil. Avoid fresh concentrated fertilizer in direct contact with young roots.
Crop growing guide
Sweet Potato
Ipomoea batatas
A spreading storage-root crop requiring healthy cuttings, loose ridges, and restrained nitrogen after canopy establishment.
Sweet potato first covers the soil with vines, then shifts assimilates into selected storage roots. Excess nitrogen or repeated vine rooting can favor foliage over marketable roots.
For practical cultivation, Sweet Potato needs its light, water, root-zone aeration, and nutrition managed as one system. The guidance below organizes those needs by growth stage; final field or container rates should follow the product label, plant size, local conditions, and soil or media analysis.
Ideal growing conditions
- Light
- Full sun for canopy production and underground storage growth.
- Climate
- Warm seasonal conditions matched to the crop, with a relatively dry harvest window.
- Water
- Even moisture during establishment and bulking; reduce excess water near harvest.
- Soil
- Deep, loose, well-drained soil without compaction or standing water.
- Soil pH
- 5.5–6.8
Nutrition by growth stage
Canopy development
Early leaf and stem expansionBalanced top growth, root exploration
Build enough Sweet Potato leaf area to power storage growth, but do not overuse nitrogen and delay root or tuber formation.
Root or tuber bulking
From storage initiation through enlargementPotassium, phosphorus, even moisture
Shift Sweet Potato toward balanced phosphorus and potassium while keeping soil loose and evenly moist.
Maturation
Final weeks before harvestSkin set, dry matter, harvest quality
Avoid late nitrogen and excess water as Sweet Potato matures; both can reduce dry matter and storage quality.
Alitura fertilizer program
Match each product to the crop stage and root zone. Final rates should follow the product label, soil condition, and local agronomic advice.
Potato Special Mix
Special organic blend formulated for vegetable plant growth and crop quality.
From IDR 28.000 / Kg(Packaging 20Kg)
Recommended for
Root or tuber bulking · Maturation
Kentang Special Mix organic nutrition can support Sweet Potato when its use follows crop stage, soil condition, and the product label.
Best timing
Introduce during active growth and the higher-demand stages listed above; avoid a large corrective dose close to harvest or dormancy.
How to apply for this crop
Apply to moist soil around the active Sweet Potato root zone, keep material away from stems or crowns, water in, and adjust the amount to plant size and field or container conditions.
General product guidance
Apply around the active root zone or mix into the planting media according to the package label, then water lightly. Adjust the amount to plant size, soil condition, and crop stage.

Green Dust
Natural Source of Potassium and Volcanic Mountain Minerals
From IDR 28.000 / Kg(Packaging 20Kg)
Recommended for
Establishment · Canopy development
potassium-rich mineral support provides a defensible foundation for Sweet Potato without replacing soil or leaf analysis.
Best timing
Use during soil preparation, establishment, or recovery, then reassess before the next growth stage.
How to apply for this crop
Spread evenly through the cultivated root zone or media, mix lightly where appropriate, and never pile fertilizer against Sweet Potato.
General product guidance
Green Dust is a fine powder mixed into soil or growing media. As a general guide, work a small handful (roughly 30-50 g per plant) into the soil around the root zone, or blend evenly through your potting/growing mix before planting. For beds and fields, broadcast lightly and incorporate into the topsoil. Apply at planting and again during the fruiting or flowering stage when potassium demand peaks. Water in well after application. Because Green Dust is high in potassium, use it as a targeted boost rather than a sole fertilizer, and pair it with a nitrogen source for balanced growth. Always confirm rates against your crop and soil conditions; when in doubt, start light and adjust.
Mistakes to avoid
- Using compacted or stony soil that deforms roots and tubers.
- Continuing heavy nitrogen after storage growth should begin.
- Keeping the root zone saturated near maturity and reducing storage quality.
- Lift or manage sprawling vines where excessive secondary rooting reduces storage-root bulking.
