Growing Spinach in Samburu
Soil suitability analysis based on Samburu's nutrient profile
Generally not ideal — Samburu is poorly suited to Spinach. Samburu's soil (pH 8.28, alkaline) gives Spinach a suitability score of 18/100. Match fertilizer to Samburu's nitrogen and phosphorus levels for the best result.
Samburu County is a challenging environment for Spinach (soil-match score 18/100) and will need significant amendment before planting. At an average pH of 8.28 the soil sits above Spinach's preferred 6–7.5 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.67 g/kg, P 42.1 mg/kg, K 387 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Spinach prefers loam soils, while Samburu is largely sandy, so drainage and organic-matter management matter more here. Samburu receives approximately 350 mm/year — well below Spinach's minimum of 600 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Spinach is the #47 soil match of the 106 crops we assess for Samburu County. Spinach's full potential is about 8,000 kg/acre (~KES 200,000/acre at KES 25/kg), but at Samburu's 18/100 suitability a realistic target here is closer to 1,800 kg/acre (~KES 45,000/acre) unless the constraints above are addressed.
Better matched to Samburu's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

| Factor | Samburu soil | Spinach needs | Status |
|---|---|---|---|
| pH | 8.28 | 6–7.5 | Adjust |
| Nitrogen | 0.67 g/kg | min 1.2 g/kg | Low |
| Phosphorus | 42.1 mg/kg | min 12 mg/kg | OK |
| Potassium | 387 mg/kg | min 150 mg/kg | OK |
| Rainfall | 350 mm | 600–1,400 mm | Low |
| Altitude | 900 m | 0–2,500 m | OK |
Top dressing guide
Samburu's nitrogen (0.67 g/kg) is 56% of the 1.2 g/kg Spinach needs, so the standard 0.5 bags/acre is raised to 0.75. Split it across two applications to limit leaching.
Recommended seed varieties
No variety in our list is specifically rated for Samburu's 900 m altitude and 350 mm rainfall, so all 2 are shown. Confirm with your agrovet before buying.
