Biomass dynamic and nutrient accumulation of natural restoration at early stage after fallow in clear-cutting forestland of Chinese fir plantation
杉木林采伐迹地撂荒后植被恢复早期的生物量与养分积累

Fallow is one of the key practices used in traditional Chinese fir management sy stem to sustain long- term site productivity through increasing soil n utrient contents. The underlying principle of the practice is based on the hypot hesis that vegetative regrowth of native plants after fallow results in the accu mulation of high nutrient contents in these plants by increasing nutrient uptake due to their root system. When the regrowth is slashed and retained on the site , the nutrients returned to soil can...
