Abstract:This article shows that ground orthoclase feldspar is a suitable source of potassium for pine seedlings. Depending on conditions, feldspars and other potash-bearing minerals or rocks may wholly or partially replace commercial potash fertilizers in forest nurseries. The use of difficultly soluble potash minerals effects a material reduction in the fluctuation of soluble salts in nursery soils.
