A nutritional study of grand fir and amabilis fir in the greenhouse

2012
Grand fir (Abies grandis (Dougl.) Lindl.) and amabilis fir (A. amabilis (Dougl.) Forbes) were grown in sand cultures from seed for two growing seasons in a greenhouse. The effects of deficiencies of nitrogen, phosphorus, potassium, calcium, magnesium, and sulphur on the growth and development of the seedlings were studied.
