Growing Parsley in Garissa

Soil suitability analysis based on Garissa's nutrient profile

Quick answer

Generally not ideal — Garissa is poorly suited to Parsley. Garissa's soil (pH 7.96, alkaline) gives Parsley a suitability score of 1/100. Match fertilizer to Garissa's nitrogen and phosphorus levels for the best result.

Garissa County is a challenging environment for Parsley (soil-match score 1/100) and will need significant amendment before planting. At an average pH of 7.96 the soil sits above Parsley's preferred 6–7.5 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.61 g/kg, P 37.7 mg/kg, K 407 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Parsley prefers loam soils, while Garissa is largely sandy, so drainage and organic-matter management matter more here. Garissa receives approximately 250 mm/year — well below Parsley's minimum of 600 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Parsley is the #76 soil match of the 106 crops we assess for Garissa County. Parsley's full potential is about 4,000 kg/acre (~KES 400,000/acre at KES 100/kg), but at Garissa's 1/100 suitability a realistic target here is closer to 50 kg/acre (~KES 5,000/acre) unless the constraints above are addressed.

Better matched to Garissa's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

Bags per acre in Garissa
0.50.3

Garissa's nitrogen (0.61 g/kg) is 51% of the 1.2 g/kg Parsley needs, so the standard 0.3 bags/acre is raised to 0.5. Split it across two applications to limit leaching.
