“…These results support previous research into this area on beneficial effects of mulch on soil activity (Tu et al 2006;García-Orenes et al 2010). Under field conditions, mulched soybean showed greater values of dehydrogenases, protease, and acid and alkaline phosphatases than unmulched soil (Siczek and Frąc 2012).…”

“…However, straw mulch effect on enzymes activities was strongly dependent on mulching levels and some adverse effects at straw mulching higher than 15,000 kg ha -1 were observed (Zhang et al 2015). Straw mulch effect on soil enzymatic activity was also dependent on soil compaction level (Siczek and Frąc 2012). The study of Govaerts et al (2007) indicated that soil microbial biomass C and N was significantly higher for residue retention compared to residue removal in a long-term field experiment.…”

The importance of flavonoids in rhizospherelegumes symbiosis has been recognized as critical. However, the limited data are available about their impact on soil microbial communities. In rhizosphere, it remains unclear whether flavonoids, mulch or their joint effects influence on soil microbial diversity and enzymes activity. Therefore, in this study, the effects of flavonoids and straw mulching on soil microbial functional diversity, fungi abundance and enzymes activity (dehydrogenases, protease, acid phosphomonoesterase) in pea rhizosphere were evaluated. The field study was conducted in Lublin, Poland (51°15 0 N, 22°35 0 E), on a Haplic Luvisol. Flavonoids were applied on pea seeds and after sowing soil surface was covered with straw mulch. In soil rhizosphere sampled three times during the vegetative period of pea were determined: dehydrogenases, protease and acid phosphomonoesterase activities, metabolic potential of soil bacteria, microbes number and predominant fungal species. The results showed that dehydrogenases and protease activities were significantly increased with time during pea growing season. Significant increase in dehydrogenases activity was observed after flavonoids and mulch influence. There was no impact of studied factors on acid phosphomonoesterase. The effects of flavonoids and mulch on biodiversity indices were related to sampling terms. Straw mulching increased potentially antagonistic fungi in pea rhizosphere. The results of this study can be useful in understanding the effects of flavonoids and mulch on microbial activity and dynamics in pea rhizosphere which is very important in soil quality and crop production.

“…Terms & Conditions of access and use can be found at http:// www.tandfonline.com/page/terms-and-conditions Introduction Soil is a complex and dynamic biological system, where microorganisms play an important role in transformation of soil organic matter and therefore can affect plants growth. Microorganisms take part in carbon, nitrogen, phosphorus and other macroelements cycles in soil environment and can transform their unavailable form into components available for plants (Magdoff & van Es 2000;Siczek & Frąc 2012). On the other hand, plants can influence microbial community by controlling the quality and quantity of organic substrates that bulk soil contains (Viketoft et al 2005).…”

Microorganisms and their interactions with plant and soil provide soil environment integrity. The structural and functional diversity of microbial population in soil is necessary to maintain resistance to environmental perturbations. The aim of this study was to compare metabolic activity and genetic diversity of soil microbial communities at different depths under two soil managements. The experiment included five following soil objects: GR20 -rhizosphere from grassland (0-20 cm), GNR20 -nonrhizosphere grassland (0-20 cm), GNR40 -nonrhizosphere grassland (30-40 cm), BF20 -bare fallow (0-20 cm), BF40 -bare fallow (30-40 cm). Metabolic activity was assessed by dehydrogenases activity and community level physiological profiling using EcoPlates. The study also included genetic diversity assessment, with the use of denaturing gradient gel electrophoresis to reveal genetic structure of ammonia-oxidizing bacteria (AOB). The results showed that soil metabolic and biological activity decreased with soil depth and decreased in bare fallow objects. Highly utilized substrates in both management systems belonged to compounds of microbial biomass. These microbial substrates were amino acids, especially L-asparagine, and fungal substrates were mannitol and N-acetyl-Dglucosamine. In grassland soil highly degraded substrates additionally included D-cellobiose and d-xylose, which are compounds of plant cell walls. Analysis of genetic differentiation among treatments showed unique AOB structure in soil rhizosphere. This was mainly caused by the availability of roots exudates, including amino acids and carbohydrates.

“…(Nannipieri et al, 2012). Several studies have focused specifically on compost and crop residues, such as straw, used as mulch or soil amendment (Siczek and Frac, 2012;TerAvest et al, 2011). In spite of this and with the exception of plant litter in natural forests and wood chips, very few of these studies address lignocellulosic residues such as those present in almond shells.…”

The recycling of almond shell as mulch would allow avocado orchards to be managed organically, maintaining plant yield and improving soil conditions simultaneously. This study aims to analyze the long term effects of successive applications of almond shell as mulching for organically grown avocado. Effects on soil properties, enzyme activities and soil carbon storage as well as avocado yield and growth were studied in comparison to no-tillage conventionally managed (using mineral fertilizers and herbicides) avocado. In 2002, 2007 and 2012 almond shells were applied in a 7 cm thick layer (26.0 kg dry matter m-2) covering 4 x 8 m per tree. After a 10 year period a new soil organic horizon was established in the organic treatment, and the upper mineral soil layer (0-25 cm) enhanced its C content from 43 g kg-1 in F to 91 in g kg-1 , and proportionally P and N contents. The high lignin content of almond shells, 362 g kg-1 , led to low organic matter degradation, 37% for the 10-year period. Nevertheless, this reduced rate of organic matter mineralization was sufficient to supply the needed nutrients and to maintain or even increase fruit yield in the organic treatment. Urease, β-glucosidase, dehydrogenase, protease and phophomonoesterase showed high microbiological activity in the organic layer decreasing in mineral layers. Enzyme activities were significantly correlated to soil OC (organic C) content and site specific soil moisture. Reduced mineralization and high surface microbiological activity make almond shell an ideal mulch for avocado trees combining increased soil organic C content and agricultural benefits.
