Abstract

In silviculture, timber cutting(nutrient output) has been studied extensively, whereas nutrient input (fertilization) has been ignored. This has led to unbalanced nutrient concentrations in soil ecosystems as well as acidic and barren soils. In southern Sichuan, an important tree plantation base in China, rainfall is the main nutrientinput source for the forest system. Results of a rainfall input analysis indicated that pH increased with rainfall, was slightly acidic with light rain, and was neutral with medium and heavy rain. Also, N, P, K, Mg and Si decreased with rainfall in the order of: Ca N K Mg P Si. The 52.26 kghm- 2a- 1 of nutrient input from rainfall in the forestsof southernSichuanwas partitioned as: N12.39 kghm- 2a- 1, P0.84 kghm- 2a- 1, K 12.27 kghm- 2a- 1, Ca 23.90 kghm- 2a- 1, Mg 2.53 kghm- 2a- 1, and Si 0.33 kghm- 2a- 1 with nutrients higher than average. In addition, the annual Si input from rainwas 1.2%- 5.5% of the Si output of timber.[Ch, 4 tab. 16 ref.]
