据1980年7月份(林业文摘)报导,1954年到1976年新西兰森林施肥面积共54529公顷,其中90%是幅射松林。1957年施用尿素,过磷酸盐和水硼酸钠计折合纯氮560吨,磷515吨,硼28吨,另外钾36吨,镁22吨,主要是苗圃施NpK复合肥料和白云石。预计1985年施用肥料将含纯氮14000吨、磷3000吨、钾70吨、镁30吨,硼130吨。据1980年4月份(林业文摘)报导,东德森林施肥(尿素)面积由1953年的10,200公顷
As reported in July 1980 (Forestry Abstracts), forest fertilization in New Zealand totaled 54,529 hectares from 1954 to 1976, 90% of which were Pinus elliottii. In 1957, urea, sodium perphosphate and sodium borate were calculated as 560 tons of pure nitrogen, 515 tons of phosphorus, 28 tons of boron and 36 tons of potassium and 22 tons of magnesium, respectively. The main application was NpK compound fertilizers and dolomite in nurseries. Fertilizers are expected to be applied in 1985 with 14,000 tons of pure nitrogen, 3,000 tons of phosphorus, 70 tons of potassium, 30 tons of magnesium and 130 tons of boron. As reported in April 1980 (Forestry Abstracts), the area of fertilization (urea) in East German forests increased from 10,200 hectares in 1953
