Understanding Soil pH
What is Soil pH?
Soil pH is a measure of the acidity or alkalinity of the soil, determined on a scale that ranges from 0 to 14. A pH of 7 is considered neutral, while values below 7 indicate acidic conditions, and values above 7 indicate alkaline conditions. Understanding soil pH is crucial for effective turf management, as it plays a significant role in the availability of nutrients essential for grass growth.
Acidic soils (pH less than 7) can hinder the availability of key nutrients, while alkaline soils (pH greater than 7) can lead to nutrient lockout, where essential elements become unavailable to plants. For instance, in acidic soils, nutrients like phosphorus can become bound to soil particles, making them less accessible to grass roots. Conversely, in alkaline soils, micronutrients such as iron may become less soluble, leading to deficiencies.
In New Zealand, soil pH can vary significantly from region to region, influenced by factors such as rainfall, parent material, and land use. Understanding the specific pH range of your soil is vital for selecting the right turf management products and ensuring optimal grass health.
