“…Values represent the mean of 12 samples ± standard error. (2000) and Campos et al (2012) argued that high rates of basal respiration can occur either as a result of a large pool of labile C substrates or rapid oxidation of a smaller pool. Thus, high basal respiration may indicate either ecological stress and degradation or a high level of ecosystem productivity.…”

© iForest -Biogeosciences and Forestry IntroductionSoil health and quality may be successfully monitored through the use of two microbial indexes: (i) the microbial biomass, which is defined by the living component of soil organic matter, excluding the macrofauna and plant roots; and (ii) soil microbial respiration (basal respiration), which is described by the respiration without the addition of an organic substrate to soil (Jenkinson & Ladd 1981, Alef 1995, Sparling 1997. The microbial biomass is small and labile as compared with other ecosystem components; however, because of its key role in the mineralization of nutrients such as C, N, P and S, it is considered a reliable indicator of changes in soil characteristics (Jenkinson & Ladd 1981, Powlson et al. 1987, Balota et al. 2003. Balota et al. (2013) report that changes in the microbial properties of soil may lead to important changes in soil quality, thus affecting nutrient cycling and plant development. Haris (2003) clearly affirmed that the microbial community serves as an indicator of the re-establishment of connections between ecological functions of the biota in disturbed ecosystems. Despite the large variations in mineralogy, soil texture and land use type, extreme environments usually show low organic matter and very low microbial biomass contents, which indicate poor soil quality and limited site productivity (Sparling 1997, Guénon et al. 2013.Soil basal respiration is a well-established parameter to be measured through the decomposition process, and it is defined as the overall activity or energy spent by the indigenous microbial pool (Anderson & Domsch 1990, Sparling 1997. Insam et al. (1991) argued that soil basal respiration reflects the availability of slow-flowing C for microbial permanence and is a measure of basic turnover rates in soil.Robinia pesudoacacia L. (black locust or false acacia) is a deciduous, broad-leaved, light-demanding, medium-sized pioneer tree ranging in height 20-25 m. Black locust is regarded as an invasive, non-indigenous species in many parts of Europe, such as Germany, Italy and Turkey (Ansin & Özkan 1997, Cierjacks et al. 2013. It is well-adapted to grow on different types of soil and environmetal conditions, though it avoids compacted or wet soils. Indeed, its demand for aerated soil is the reason why black locust can be primarily found in disturbed sites from poor to fertile soils (Sabo 2000, Cierjacks et al. 2013. Black locust shows a rapid growth and adaptability, for it has been utilized for soil conservation or fuel wood, as well as for early reforestation of barren soils at disturbed sites (Landgraf et al. 2005, Keskin & Makineci 2009, Noh et al. 2010). However, in Turkey it has been long cultivated as an ornamental plant and it can be currently found in schoolyards, roadsides or other marginal lands (Ansin & Özkan 1997). This tree species is characterized by an extensive root system (Zhou & Shangguan 2005) nodulated by diverse nitrogen-fixing Rhizobium communities, providing the host with an advantage over na...

“…Application of organic materials as soil amendments is an important management strategy that can improve and uplift soil-quality characteristics and alter the nutrient cycling through mineralization or immobilization turnover of added materials (Khalil et al, 2005;Campos et al, 2013;Baldi and Toselli, 2014;Novara et al, 2013;Hueso-González et al, 2014;Oliveira et al, 2014). Use of local organic materials derived either from livestock or plants have been attaining worldwide support for improving the fertility and productivity potential of degraded and nutrient-poor soils (Huang et al, 2004;Tejada and Benítez, 2014).…”

Abstract. Application of plant residues as soil amendment may represent a valuable recycling strategy that affects carbon (C) and nitrogen (N) cycling in soil-plant systems. The amount and rate of nutrient release from plant residues depend on their quality characteristics and biochemical composition. A laboratory incubation experiment was conducted for 120 days under controlled conditions (25 • C and 58 % waterfilled pore space) to quantify initial biochemical composition and N mineralization of leguminous and non-leguminous plant residues, i.e., the roots, shoots and leaves of Glycine max, Trifolium repens, Zea mays, Populus euramericana, Robinia pseudoacacia and Elaeagnus umbellata, incorporated into the soil at the rate of 200 mg residue N kg −1 soil. The diverse plant residues showed a wide variation in total N, C, lignin, polyphenols and C / N ratio with higher polyphenol content in the leaves and higher lignin content in the roots. The shoot of Glycine max and the shoot and root of Trifolium repens displayed continuous mineralization by releasing a maximum of 109.8, 74.8 and 72.5 mg N kg −1 and representing a 55, 37 and 36 % recovery of N that had been released from these added resources. The roots of Glycine max and Zea mays and the shoot of Zea mays showed continuous negative values throughout the incubation. After an initial immobilization, leaves of Populus euramericana, Robinia pseudoacacia and Elaeagnus umbellata exhibited net mineralization by releasing a maximum of 31.8, 63.1 and 65.1 mg N kg −1 , respectively, and representing a 16, 32 and 33 % N recovery, respectively. Nitrogen mineralization from all the treatments was positively correlated with the initial residue N contents (r = 0.89; p ≤ 0.01) and negatively correlated with lignin content (r = −0.84; p ≤ 0.01), C / N ratio (r = −0.69; p ≤ 0.05), lignin / N ratio (r = −0.68; p ≤ 0.05), polyphenol / N ratio (r = −0.73; p ≤ 0.05) and (lignin + polyphenol) : N ratio (r = −0.70; p ≤ 0.05) indicating a significant role of residue chemical composition and quality in regulating N transformations and cycling in soil. The present study indicates that incorporation of plant residues strongly modifies the mineralizationimmobilization turnover (MIT) of soil that can be taken into account to develop synchronization between net N mineralization and crop demand in order to maximize N delivery and minimize N losses.

“…The chronosequence approach is frequently used to evaluate plant succession after disturbance, comparing sites that differ only in time since agricultural abandonment Rühl et al, 2005). The climatological gradient approach is also applied in soil science, hydrology and geomorphology (Campos et al, 2014;Cerdà, 1998a;Lozano-García et al, 2016;Parras-Alcántara et al, 2015).…”
