“…Application of organic manure increased stocks of SOC and SMBC. On one hand, this could be caused by the higher amount of organic carbon and microbial biomass carbon added by organic manures, and on the other hand, increased carbon input resulted in long-term nutrient accumulation (Kaur et al 2005 ; Joergensen et al 2010 ; Wang et al 2010 ), so TN, TP and TK in organic manure treatments were significantly higher than those in mineral fertilizer treatments. Long-term mineral fertilizer applications resulted in loss of organic matter (Jenkinson 1991 ; Aref and Wander 1997 ).…”

In this study, the effect of mineral fertilizer and organic manure were evaluated on soil microbial biomass, dehydrogenase activity, bacterial and fungal community structure in a long-term (33 years) field experiment. Except for the mineral nitrogen fertilizer (N) treatment, long-term fertilization greatly increased soil microbial biomass carbon (SMBC) and dehydrogenase activity. Organic manure had a significantly greater impact on SMBC and dehydrogenase activity, compared with mineral fertilizers. Bacterial and fungal community structure was analyzed by polymerase chain reaction (PCR)-denaturing gradient gel electrophoresis (DGGE). Long-term fertilization increased bacterial and fungal ribotype diversity. Total soil nitrogen (TN) and phosphorus (TP), soil organic carbon (SOC) and available phosphorus (AP) had a similar level of influence on bacterial ribotypes while TN, SOC and AP had a larger influence than alkali-hydrolyzable nitrogen (AHN) on fungal ribotypes. Our results suggested that long-term P-deficiency fertilization can significantly decrease soil microbial biomass, dehydrogenase activity and bacterial diversity. N-fertilizer and SOC have an important influence on bacterial and fungal communities.Electronic supplementary materialThe online version of this article (doi:10.1007/s13213-014-0889-9) contains supplementary material, which is available to authorized users.

“…Recently, the plantation area of Chinese fir has been enlarged due to an increased demand for timber. However, the yield and productivity of pure Chinese fir plantations are extremely low because of low photosynthetic efficiency, poor soil fertility, and nonscientific management practices (Wang et al 2010;Tian et al 2011;Zhang and Wang 2012). Continuous planting on the same site is an important reason for the decline in soil fertility and the decreases in wood volume and productivity (Ding and Cheng 1995;Zhang et al 2004;Tian et al 2011).…”

Abstract& Key message A high-density plantation inhibited growth and biomass accumulation of Cunninghamia lanceolata (Lamb.) Hook. saplings, as well as their photosynthesis. This inhibition was enhanced in a soil that had been previously planted with the same species. The main factors limiting photosynthesis and growth were leaf-level irradiance and nutrient availability, mainly of P and Mg. & Context The planting density and continuous planting greatly affect the photosynthesis and productivity of Chinese fir plantations. The effects of high density and of continuous plantations over several revolutions need be disentangled. & Aims In this study, the responses of C. lanceolata seedlings to a high planting density were tested. Two soils were compared: a soil from a secondary forest and one from a continuous Chinese fir plantation. The study focused on growth and the potential processes involved in deduced photosynthesis. & Methods C. lanceolata seedlings were planted in wooden boxes (100×100×50 cm) with high and low planting densities (16 vs 1 plant m −2 ) in two types of soil. & Results Under the high planting density, C. lanceolata showed less growth and biomass accumulation at the individual level and lower photosynthetic rate and instantaneous photosynthetic nutrient use efficiency (PNUE and PPUE) at the leaf level. These negative effects were larger in soils that have been continuously planted with Chinese fir. The low photosynthesis was related to low phosphorus and magnesium contents in the leaves, changes in the foliar N/P and chlorophyll a/b ratios, and the limitation of the mesophyll conductance. & Conclusions The study showed that a high planting density induced enhanced competition for nutrients (particularly for P and Mg) and that this competition is enhanced in soils from continuous plantations compared to soils from natural forests.

“…Although there have been many studies on microbial properties in different forest ecosystems (Aikio et al 2000;Wang and Wang 2008;Wang et al 2010;Susyan et al 2011;Wang et al 2011), processes and changes that occur during forest succession are poorly understood, particularly in the subtropical zones of China. Subtropical zones were originally primary forests that have been disturbed by human activities during the past centuries.…”

To better understand the effects of forest succession on soil microbial activity, a comparison of soil microbial properties and nutrients was conducted between three forest types representing a natural forest succession chronosequence. The study compared a pine (Pinus massoniana) forest (P F ), a pine and broadleaf mixed forest (M F ) and an evergreen broadleaf forest (B F ), in the Yingzuijie Biosphere Reserve, Hunan Province, China. Results showed that soil nutrients in the M F and B F plots were higher than in the P F plots. The range in microbial biomass carbon followed a similar pattern with B F having the greatest values, 522-1022 mg kg -1 , followed by M F 368-569 mg kg -1 , and finally, P F 193-449 mg kg -1 . Soil nutrients were more strongly correlated with microbial biomass carbon than basal respiration or metabolic quotient. Overall, forest succession in the study site improved soil microbial properties and soil fertility, which in turn can increase primary productivity and carbon sequestration.
