Agricultural practices can contribute to soil acidification, or the drop in soil pH.

This can be due to several factors including leaching of nitrate nitrogen, nutrient uptake by crops and root exudates, the build-up of soil organic matter and use of nitrogenous fertilisers containing ammonium and urea.

Choosing the right lime product and applying it at the correct rate is important to manage soil acidification and the subsequent impact on vegetable crops.

Read this useful fact sheet from the Soil Wealth ICP project to find out more about the causes and effects of soil acidification, how liming increases soil pH differently depending on your soil type and tips to manage paddock variability.
