Potassium Budget for Forest Nursery Soil

Abstract:

Fertilizer potassium is lost rapidly by leaching and fixation from the pool of exchangeable potassium in a sandy, forest nursery soil during the first year of seedling growth. In the second year, when the seedlings require large quantities of this element, the supply of exchangeable potassium is depleted to very low levels. This study shows that it would be very difficult to build up appreciable reserves of available potassium in sandy nursery soils, and it is questionable whether the potassium requirement of a 2-year-old seedling crop can be met by a single, presowing fertilizer application.
