The soil properties of planted forests – topsoil depth, soil structure, rooting depth, hard pans, erosion risk, soil texture, water holding capacity, nutrient supply – all have an impact on forest productivity. Below see some videos that explain soil sampling to determine productivity of forest soils:

- Planted Forest Soils (Scion publication, August 2017)
Planted forest soils provide many benefits including growing timber and fibre, cleaning water through filtering, and regulating flooding by storing water. New Zealand has a wide diversity of soil types. They are generally young and naturally acidic with low levels of nitrogen, phosphorus, and sulphur. Planted forests are typically on low fertility or steep terrain land that is not suitable for agriculture. Best management practices and ongoing improvements are needed for planted forest soils to continue to provide multiple benefits to New Zealanders. This includes maintaining fertility in a low nutrient input production system, especially as many of New Zealand’s planted forest soils are now supporting their third rotation There are also challenges in reducing soil loss through erosion in steep, erodible country, particularly during harvest.
