“…Therefore, the C : N : P stoichiometry of soil microbes during vegetation restoration is nutrient dependent, and is not homeostatic, on the Loess Plateau (Peng & Wang, 2016). Our results support those of Zhang, Xu, et al (2019).…”

“…Increased SOC, STN, and STP content generates substrates for use by microorganisms, accelerating the metabolism of microorganism (Bowles, Acosta-Martinez, Calderon, & Jackson, 2014), and promoting soil enzyme activities. Soil available nutrients also impact soil enzyme activity (Cui et al, 2018b;Xu et al, 2017;Zhang, Ai, et al, 2019;Zhang, Xu, et al, 2019).

Soil ecoenzymatic stoichiometry reflects the nutrient flow of ecosystems. While knowledge exists on how the secondary succession of plants affects soil physicochemical properties and soil ecoenzymatic activity, less is known about how soil ecoenzymatics change during this process. We investigated five typical stages of the entire succession process of vegetation on the Loess Plateau, China. These stages included: (1) farmland stage (0 years), (2) grassland stage (30 years), (3) shrub land stage (60 years), ( 4) the pioneer forest stage (100 years), ( 5) the climax community stage (160 years). Soil ecoenzymatic activity, microbial biomass, and soil physicochemical properties were measured. Our research showed secondary succession significantly changed soil enzyme activity, and the metabolic activity of soil microorganisms significantly declines as secondary succession progresses. N limitation in the soil microbial community was weak initially and then gained strength. P nutrient limitation was strong initially, and then weakened. Soil ecoenzymatic C : N : P acquisition ratios deviated from 1 : 1 : 1. Thus, secondary succession on the Loess Plateau is nutrient dependent, but not homeostatic. Soil physicochemical properties and plants were important factors for soil enzyme activities. In addition, soil available nutrients were better than soil total nutrients to reveal changes in soil ecoenzymatic activities and stoichiometry.This study demonstrated the regularity of soil nutrient cycling during the secondary succession of vegetation, providing new insights on the mechanisms of nutrient flow.

“…The soil properties also determined the soil enzyme activities under temporal variation, particularly for soil dissolved organic matter (DOM, mainly referred to as DOC and DON) ( Figure 4). This has also been reported in previous field manipulation experiments [40] and in consistent with our previous study [41]. The DOM will stimulate the plants and soil microbes to release more enzymes that promote the decomposition process and eventually lead to the temporal variation in soil enzyme activities [7,42].…”

Variability in soil enzyme activity may have important implications for the knowledge of underground ecosystem functions driven by soil extracellular enzymes. To illustrate the temporal variation in soil enzyme activity after afforestation, we collected soil samples during different vegetative growth periods in three Caragana korshinskii Kom. stands of different ages (20, 30, and 40 years) and in a slope cropland in the Loess Plateau. These samples were used to analyze the catalase, sucrase, urease and alkaline phosphatase activities, the soil water content and the available soil nutrients (i.e., dissolved organic carbon, dissolved organic nitrogen, and available phosphorus). The results illustrated that the soil enzyme activities significantly increased following afforestation and varied with temporal variation. Overall, soil enzyme activities were higher in June and August, particularly, and both alkaline phosphatase and sucrase were more sensitive to temporal variation than the other two enzymes. In addition, redundancy analysis showed that soil enzyme activities were greatly correlated with soil nutrients, especially for dissolved organic carbon and dissolved organic nitrogen. Therefore, the results highlighted the importance of soil enzyme activities to soil nutrients under temporal variation following afforestation in the Loess Plateau, which may have practical significance for forest managers’ fertilization management of plantation in different seasons and different stand ages.

Over 80% of tree species form ectomycorrhizal (ECM) symbionts, which are essential for maintenance of forest ecosystem health and effective soil nutrient uptakes by host trees (Barrett et al., 2011;Smith & Read, 2008). The ECM roots facilitate soil nutrient uptake through branching root tips and emanating hyphae. The ECM-infested roots vary greatly in shape and structural configurations (Agerer, 1987(Agerer, -2006Agerer, 1991) and are functionally differentiated in the capacity of soil exploration range. Agerer (2001) classified the ECM roots into five types based on the extent of soil exploration: the contact exploration (smooth mantle and only a few emanating hyphae), the short-distance exploration (ECM root with a voluminous envelope of emanating hyphae but no rhizomorphs), the medium-distance exploration (ECM root with rhizomorphs), the long-distance exploration (ECM root with long
