Urban or rural fragments: which soil use in forest surroundings induces greater litter deposition?

The aim of the present experiment was to determine if the supply of biofertilizers could differently stimulate the native microbiota, thus determining different patterns of organic material decomposition processes. The microbial composition of soil and litter was investigated by next generation sequencing using a metabarcoding approach. The chemical structure of the decomposing litterbags was investigated through the TG-DTA analysis and NIR spectroscopy. The study was conducted in an apricot orchard in Italy, and two different type of biofertilizers (AMF and Trichoderma spp.) were compared to unfertilized control over one year. Bacteria and fungi in soil, 162 days from litter deposition, evidenced differentiated clusters for control and both biofertilizers; on the other hand, only fungal composition of litterbags was modified as a consequence of Trichoderma spp. supply; no effect was observed in the bacterial community of litterbags. NIR and TG-DTA analysis evidenced a significant change over time of the chemical composition of litterbags with a faster degradation as a consequence of Trichoderma spp. supply testified by a higher degradation coefficient (1.9) than control (1.6) and AMF (1.7). The supply of biofertilizers partially modified the bacteria community of soil, while Trichoderma spp. Influenced the fungal community of the litter. Moreover, Trichoderma spp. Evidenced a faster and higher degradation of litter than AMF-biofertilizers, laying the foundation for an efficient use in orchard.

Abstract The invasive Cryptostegia madagascariensis occupies riparian areas covered by tropical Cambisols throughout the North-eastern Brazil however litter is known regarding its ability to impact litter inputs, and ecosystem processes. This study aimed to characterize the effects of the invader on the litter deposition, soil physical-chemical properties, litter nutrient content, and the litter decay rate in a Tropical Cambisol. Comparisons of native and invaded environments showed that C. madagascariensis alters the quantity of litter deposition during both dry and rainy seasons. In contrast to native species, C. madagascariensis litterfall displayed litter seasonal variation (rainy vs. dry season), however invaded sites had higher litter biomass compared to native sites. C. madagascariensis litter was enriched in soil organic matter, N, P, and K contents as compared to the native litter. Compared to native environments, invaded ones had significantly decreased soil temperature and soil water content. Results suggest that C. madagascariensis enhances litter and N, P, and K availability in ways that have potential to impact soil ecosystem in the Tropical Cambisols from Caatinga ecoregion, Brazil.

The One

The litter is an important way of returning the organic matter to the soil, through the cycling of the nutrients, aiding in the development of the vegetation present in the ecosystems. The study aimed to estimate the spatio-temporal variation of deposition, accumulation and decomposition of the litter present in the preserved caatinga vegetation, located in the RPPN Fazenda Tamanduá in Santa Terezinha-PB, Brazil and the interference of climatic variables in the dynamics of these events. The research was conducted at RPPN Fazenda Tamanduá, in Santa Terezinha-PB, Brazil. The deposition of litter on 20 collectors of 1.0 m × 1.0 m was collected monthly in two periods: period I (August/2015 to July/2016) and period II (August/2016 to July/2017), the collected material was separated into leaves, branches + barks, reproductive and miscellaneous fractions. To estimate the rate of decomposition the litter accumulated on the forest floor was quantified using a 0.5 m × 0.5 m metal frame. The deposition of the total litter in periods I and II was 2,356.83 kg ha-1 and 1,163.67 kg ha-1, respectively. The leaf fraction was the one that contributed the most during the two collection periods. The analysis of the data allowed to conclude that the total litter deposition in the two periods is in line with the average production for the Caatinga. The increase in precipitation provided higher deposition of litter after the rainy season. Due to several factors, the decomposition of litter in the caatinga is slower than in other biomes.
