“…In the present study, N concentration was significantly higher in the fraction of the thin roots and the lowest in the stump. The N loss due to stump removal was 167 kg ha À1 at the Elva site (Table 7), which is almost two times higher than that reported in a Finnish study (Merilä et al, 2014). However, both average N concentrations in the different fractions and harvested stump biomass were mostly higher in our study than in the Finnish case (Hellsten et al, 2013).…”

“…At nutrient-poor sites additional nutrient removal may cause significant depletion of the soil. The extent of nutrient removal depended on the tree species, the harvesting method and the intensity of harvesting (Merilä et al, 2014). Stump lifting may affect also nutrient transformation processes in the soil e.g.…”

“…We had no data about aboveground biomass and nutrient accumulation before the clear-cut of the study sites. However, spruce allocates a considerable share of nutrients in the foliage (Lõhmus, 1987;Palviainen and Finer, 2012;Merilä et al, 2014) and in the case of ''stems + stumps'' harvesting a large amount of nutrients remains at the site.…”

“…For example, forest residue decomposition and nutrient release affect the storage characteristics of soil nutrients and improve the soil nutrient supply capacity (Hyvönen et al 2000;Merilä et al 2014). Organic management has been advocated to improve the sustainability of apple production systems (Reganold et al 2001).…”

Changes in the physical structure and nutrients contents of apple branches were explored after decomposition, and the soil quality of an orchard was evaluated after returning apple branches in situ. Scanning electron microscopy, X-ray diffractometry, and Fourier transform infrared spectroscopy were used to analyse the structural changes of the experimental material. The results showed that the structure of this material is obviously destroyed in the transverse sections and longitudinal sections. Collapsed cell walls had a negative effect on complete branches, which presented sharp decreases in cellulose contents and the partial removal of lignin and carbohydrate contents by the third year. In a final analysis of the nutrients in the branches, there was an obvious decline in macroelements (e.g., phosphorus and potassium), whereas manganese, which is a limiting factor, increased by 4-fold compared with the control. The results indicated that the addition of mulch from branches can be used to maintain a high soil quality in the third year of decomposition.

“…In managed forest ecosystems the increased demand on the use of post-harvest residues is likely to cause signifi cant decreases in soil biodiversity, soil fertility and stability (Helmisaari et al 2011 ;Merilä et al 2013 ). Many of the factors negatively infl uencing soil biodiversity are discussed in Chap.…”

Interactions in Soil: Promoting Plant Growth

View full text Add to dashboard Cite

Soil is a complex milieu of physical and biological entities that regulates the availability of nutrients for plant growth. The interactions between the elements of the soil biota and the plants during this process are complex and often rely on feedbacks between the plants and the great diversity of soil organisms that function to regulate processes to support plant growth. The rhizosphere and its mycorrhizal component are important parts of the connection between the plant and soil through its roots. This zone is a 'hot-spot' of microbial activity and trophic interactions with other soil organisms. It is here that growth of the plant root is infl uenced by nutrient availability, induction of root growth stimulating auxins, the interaction with plant pathogens and herbivores. Ecosystem engineers in the form of earthworms and other burrowing fauna are important in altering both the physical structure of soil and rates of decomposition of organic residues. A little researched component of soil is viruses. Their interaction with microbial and faunal communities is introduced here. Many of the soil processes infl uencing plant growth and the diversity of soil organisms is infl uenced by human activities ranging from agricultural and forestry practices through urbanization to the infl uence of pollution from industrial processes. To help us with the understanding of the interactions between biodiversity and function, new molecular tools involving metagenomics and transcriptomics are evolving, and are discussed here as an emerging suite of tools that can be applied to soil ecology. The chapter introduces the detail to come in subsequent chapters of this book.
