Soil acidification, the drop in soil pH, is due to several factors including leaching of nitrate nitrogen, nutrient uptake by crops and root exudates, 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 in managing soil acidification and the subsequent impact on vegetable crops.

Read this useful fact sheet to find out more about the causes and effects of soil acidification, how liming increases soil pH differently depending on your soil type, different products, as well as managing paddock variability.
