Managing Soil pH For Optimum Turf Quality

Soil pH is the foundation of soil fertility and turfgrass nutrition. It is measured on a logarithmic scale, with each pH unit representing a tenfold change in relative acidity or alkalinity. Cool eason turfgrasses prefer a pH range of 6.5-7.0 where nutrients are at their greatest level of availability. Soils with a pH below 5.5 can be toxic to turf growth. Soil pH is driven primarily by climate, arent soil material, irrigation water quality and to a lesser degree, nitrogen fertilization. Acidic soils should be amended with lime. In specific circumstances, alkaline soils can be amended with elemental sulfur…
