Growing Garlic in Kisii
Soil suitability analysis based on Kisii's nutrient profile
Possible but challenging — Kisii is only marginally suited to Garlic. Kisii's soil (pH 5.21, strongly acidic) gives Garlic a suitability score of 42/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Kisii County is a challenging environment for Garlic (soil-match score 42/100) and will need significant amendment before planting. At an average pH of 5.21 the soil is moderately acidic, below Garlic's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen and potassium — measured at N 1.09 g/kg, P 13.1 mg/kg, K 151 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing those deficits. Garlic prefers sandy loam soils, while Kisii is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Garlic is the #79 soil match of the 106 crops we assess for Kisii County. Garlic's full potential is about 3,000 kg/acre (~KES 825,000/acre at KES 275/kg), but at Kisii's 42/100 suitability a realistic target here is closer to 1,575 kg/acre (~KES 433,125/acre) unless the constraints above are addressed.
Better matched to Kisii's soil: Tea, Macadamia, and Pineapple — each scores higher on the same soil.

Top dressing guide
Kisii's nitrogen (1.09 g/kg) is 91% of the 1.2 g/kg Garlic needs, so the standard 0.5 bags/acre is raised to 0.75. Split it across two applications to limit leaching.
