“…The plant species of the mangroves have their development influenced by the physical and chemical soil characteristics [30] which may compromise the growth and structure of species [31]. Texture, potential redox, pH, cation exchange capacity, organic carbon and electro conductivity can influence nutrient uptake by plants, despite the difference of selectivity of each species to remove nutrient from the same environment [32][33][34].…”

The preservation of mangrove ecosystem requires knowledge on soil Morphology, Physical and Chemical Characteristics, for understanding the requirements for their sustainability and preservation. Seven pedons of mangrove soil, five under fluvial and two under marine influence, located in the Subaé River basin were described and classified.Samples of horizons were collected for physical and chemical analyses, including Pb and Cd. The moist soils were suboxidic, with Eh below 350 mV. The pH of the pedons under fluvial influence ranged from moderately acid to alkaline, and pedons under marine influence was around 7.0. Mangrove soils under fluvial influence were characterized with the highest Pb and Cd concentrations in the pedons, which could be perhaps due to it closeness to the mining company Plumbum, while the lowest Pb concentrations was registered in the pedon furthest from the factory. Because the pedons had at least one metal above the reference level they were considered potentially toxic. The soils were classified as Gleissolos Tiomórficos Órticos (sálicos) sódico neofluvissólico, according to the Brazilian Soil Classification System and as Thiomorphic orthic Gleysol (salic) sodicluvissol (potentially toxic, very poorly drained) according with FAO. The pedon under marine influence was classified in the same subgroup, but the metal concentrations met the acceptable standard.

“…Nutrient levels in mangrove leaves are species-dependent (Sereneski-De Lima, et al, 2013aMadi, et al, 2015. However, variations exist due to site conditions, seasons, and the biotic alteratins of the environment's physicochemical setting (Deborde, et al, 2015;Medina, et al, 2015).…”

“…However, variations exist due to site conditions, seasons, and the biotic alteratins of the environment's physicochemical setting (Deborde, et al, 2015;Medina, et al, 2015). For instance, higher K levels in the leaves of two Brazilian mangroves; R. mangle and Laguncularia racemose were reported in the dry season, whereas Ca and Cu were found to be high in the rainy season (Bernini, et al, 2010;Madi, et al, 2015).…”

The wastewater discharge into the marine environment may affect the integrity of the mangrove ecosystem. In this context, the possible effect of secondary-treated municipal wastewater discharge on the nutrient concentrations in the leaves and soils of Tubli Bay gray mangrove (Avicennia marina (Forsk.) Vierh.) was assessed at three sites. Physical properties and the percent of organic matter content in mangrove soil were measured. The nitrogen concentration was measured using the Kjeldahl method. Extractable phosphorus was quantified using the dry-ash method. Plant and soil concentration of K, Ca, Mg, and Na was determined using an inductively coupled plasma analyzer. Soil organic matter was estimated using the dry-ash method. The results showed no significant differences in the mangrove leaves’ nutrient concentration between sites regarding all the measured variables except N and Na. Wastewater discharge significantly affects mangrove leaves N content at the Tubli site where heavy wastewater loads are discharged. Leaf nutrients’ concentration followed the order: Na> K> N> Mg> Ca> P. Nutrients were concentrated in the topsoil layers in the following order: Ca > Mg > Na > K > N > P. Nutrient level showed a decreasing pattern with soil depth, except for Ca. Significant differences were observed in N and P’s levels in the soil layers between the affected site and the other two sites. Furthermore, the soil analysis indicated significant differences in N and P levels in the Tubli site soil compared to the other two sites due to wastewater discharge. No significant correlations were found between nutrient levels in the leaves of mangrove and its underlying soils. Additionally, the release of wastewater into the Bay significantly increased soil organic matter in the affected site. The study’s findings indicate that the continued release of the secondary effluent into the Tubli Bay may alter the Bay ecosystem’s Physico-chemical properties in general and mangrove survival in particular.
