This document discusses soil pH tolerances for various vegetable crops. It divides crops into four categories based on their pH preferences: acid soil crops that prefer pH 4.0-5.5, somewhat acid soil crops with pH 5.0-6.5, very acid to alkaline soil tolerant plants from pH 5.0-7.0, and moderately alkaline soil plants tolerating pH 6.0-7.5. Each category lists the crops and their optimum pH ranges. The document provides a detailed yet concise reference for matching vegetable crops to different soil acidity levels.
