“…Badacsonyi, Bates & Tuba (2000) observed in a non-Mediterranean temperate ecosystem that P and K absorption were not affected by drought in some moss species, but also that in some cases drought increased the capacity to retain K in biomass. Sottocornola, Boudreau & Rochefort (2007) observed that increases in P availability and capture enhanced the moss's rewetting capacity when water availability increased.…”

We conducted a 6 year field experiment in an evergreen Quercus ilex forest where we simulated the increased drought projected by Global Circulation Models (GCM) and ecophysiological models for the immediate decades. We tested the hypothesis that enhanced drought will change C, N, P, K, Ca, Fe, Mg, Mo and S concentrations of the widespread moss Hypnum cupressiforme Hedw. and its capacity to absorb nutrients of soil-borne or airborne origin. During the period of study, from 1999 to 2005, the soil moisture in the drought treatment was on average 9% lower than the soil moisture in the control plots. Drought increased the K concentration by 10% and the C concentration by 6%, and decreased the Fe and Mo concentrations by 33% and 18%, respectively, and the N/P content ratio by 15%. A principal component analysis showed that 69% of the variation in moss elemental concentrations is explained by the drought treatment. Drought increased the enrichment factors of several elements, mainly of P, K, Ca, Mg, S and Mo, relative to bedrock extracts, thus showing that the proportion of these elements absorbed from the atmosphere had been increased by drought. The results show that drought increased the concentration of elements linked to drought resistance such as C and K, and decreased the contents of others important for plant productivity such as Mo and Fe. Drought thereby changed moss stoichiometry, and this could also affect the palatability and quite probably, the moss-herbivore relationships and decomposition rates.

“…Moss affects soil properties; in particular, it alters soil fertility through the accumulation of total N, K or alkali-soluble N, available K, P, and organic matter in the soil [14,15]. For example, moss enriches the P in soil during moss growth [16]; i.e., the more P is absorbed by mosses, the less P is left in the soil [17]. Meanwhile, moss is very sensitive to its environment and easily alters the water content and the nutrients in the environment with its growth [18][19][20][21].…”

Using moss as a bio-indicator to evaluate soil quality in litchi orchard

Moss, was frequently found growing in litchi orchards. However, less known about whether it can be used as a visual bio-indicator for evaluating soil fertility and health. Therefore, soil chemical and biological properties, microbial community structures and the metabolic functions of microbes in soils between moss- and non-moss-growth areas were analyzed using traditional and high-throughput sequencing technologies. The results showed that pH and the contents of and available phosphorus (AP) in moss growth areas were significantly lower than those of non-moss growth areas, but the contents of alkali-hydrolyzable nitrogen (AN) and available potassium (AK) were significantly increased. In comparison with the soil of the non-moss-growth area, the abundances of hypotrophic microorganisms, such as Chloroflexi, Cyanobacteria and WPS-2 enriched in the soil of the moss-grown area. Moreover, the proportions of eutrophic microorganisms, such as Proteobacteria and Firmicutes also declined in the soils of the moss-growth area. Furthermore, the metabolic pathways of soil bacteria and fungi were also degraded in the moss-growth area. All above results indicated that not only lower soil fertility, but also soil microbial diversity also declined in moss growth area which compared to those of non-moss growth area. In one word, moss can be considered using as a visual bio-indicator for representing soil degradation in litchi orchards.
