“…This high pH values correspond with data from the other reclaimed soils in the Most region (Růžek et al 2003). From this aspect, the environment was markedly unnatural for the growth of domestic forest tree species (Andersson et al 2004). Development of the pH value between the first and the second monitoring period documents a gradual decrease in the soil reaction on the research plots (approximately about 0.5 degree after 5 years).…”

ABSTRACT:The paper presents the results of relatively long-term research focused on spoil bank revitalization processes in the North Bohemian Brown Coal Basin after the first three years of observations. The biological activity of soil (namely catalase and phosphatase activity), indicators of basal and potential soil respiration, ammonification and growth, development and nutrition status of forest plantations were selected as indicators of this revitalization process. These parameters were determined in five localities of different age of reclamation where different technological approaches and tree species compositions were used. The results confirm the distinct time dependence of revitalization processes. From the aspect of biological activity older reclamations are close to natural forest soil. The enrichment of top soil layer with organic matter before the plantation (by ploughing in cellulose fibres and peat addition) increased some parameters of soil biological activity. The positive amelioration effect of black alder (Alnus glutinosa) was also confirmed.

Soil Health refers to the ecological equilibrium and the functionality of a soil and its capacity to maintain a well balanced ecosystem with high biodiversity above and below surface, and productivity. To understand and use soil health as a tool for sustainability, physical, chemical, and biological properties must be employed to verify which respond to the soil use and management within a desired timescale. Attributes with a rapid response to natural or anthropogenic actions are considered good indicators of soil health. Among the physical indicators, soil texture, aggregation, moisture, porosity, and bulk density have been used, while among chemical indicators total C and N, mineral nutrients, organic matter, cation exchange capacity, among others are well established. However, most of them generally have a slow response, when compared to the biological ones, such as microbial biomass C and N, biodiversity, soil enzymes, soil respiration, etc., in addition to macro and mesofauna. Thus, a systemic approach based on different kinds of indicators (physical, chemical and biological) in assessing soil health would be safer than using only one kind of attribute. Many human activities have caused desertification, loss of biodiversity, disruption of aggregates, loss of organic matter and nutrients, among others. Today, it is imperious to maintain soil health and productivity with increasing emphasis on reforestation and recuperation of degraded areas through the use of organic amendments, reintroduction of plants, soil fauna and microorganisms. This review focused on an integrative view on indicators of soil health to be used as tools for prediction of sustainability in production systems.

“…In the early stage, N addition may increase the decomposers' activity (Molina et al 1983;Madritch and Hunter 2003) and promote N release. However, in the later stage, the cumulative N addition effect tends to induce C-based limitation of microbial decomposer activity (Thirukkumaran and Parkinson 2000;Andersson et al 2004), limiting N release. In the present study, N loss in the CM plots was faster under the three N addition treatments than the control group in the first 8 months of decomposition but became significantly slower under N60 and N90 treatments after 12 months (Fig.…”

Aims The litter decomposition effects of N deposition in combination with management practices are still unclear. The aims of this study were to test the individual and interactive effects of the two factors on Moso bamboo leaf litter decomposition. Methods The experiment was conducted in Moso bamboo forests over a 24-month period and included three N addition treatments (low N, 30 kg N ha −1 yr −1 ;medium N, 60 kg N ha −1 yr −1 ; and high N, 90 kg N ha −1 yr −1 ) and two management practices (conventional management and intensive management). Results The low-N treatment significantly increased the annual decomposition rate, whereas the high-N treatment significantly decreased the annual decomposition rate (P<0.05). Intensive management alone did not significantly influence decomposition, but it amplified both the positive effects of the low-N treatment and the negative effects of the high-N treatment on litter decomposition. Intensive management weakened the positive effects of N addition on N loss but enhanced the positive effects on P loss during the early stage. Conclusions The effects of increasing N deposition in a plantation ecosystem were altered by the management practices, and these changes should be considered when estimating the biological effects of N deposition at regional and global scales.
