“…In a sense, salt marsh deposits may be termed either soil or sediment because of their many ambivalent characteristics (Edelman and van Staveren, 1958;Cotnoir, 1974). Marsh substrates commonly exhibit inherent pedologic structures (in addition to sedimentary structures) and identifiable soil types and horizons.…”

“…The above ground mangrove biomass correlated significantly with soil factors (Boto and Wellington, 1984). Many marsh soils contain large amount of sulphur which is oxidized to sulphate when exposed to air (Cotnoir, 1974). Mangrove soils generally were high in clay, organic matter, cation exchange capacity, Al, SO4 , Fe and exchangeable bases than non-mangrove soils.…”

The present study provides an analysis the growth performance of mangrove forests (Avicennia marina and Rhizophora mucronata) and the concentrates on the environmental factors (soil) that affect on the mangroves along Egyptian-African Red Sea coast. The growth performance of R. mucronata was higher in association with A. marina than in pure stands. Moreover, A. marina trees growing in association with R. mucronata were taller than plants growing in pure community. Plants growing (size index) at high tide attained the highest values of growth attributes. In comparison, A. marina growth attributes differed between the three locations of the three tide levels. The highest values of the growth parameters were recorded for A. marina growing at the medium tide in pure stands. However, the growth values of A. marina growing in mixture with R. mucronata were higher at low tide than those at either high or medium tides. The total mean of Soil Bulk Density (SBD) of the A. marina (1.24 g cm³) was higher than that of the R. mucronata (1.16 g cm³) and mixed stands (1.12 g cm³). The results shows that both ordination techniques clearly indicated that electric conductivity, CaCO3, K+, Ca++, Cl-, Na+ and Mg++ were the most important parameters determining the current distribution of mangrove pattern in the Egyptian Red Sea coast. The results showed that there is a similarity between the soil samples in different of the study locations as whole area is a coastal. In the current study the variability of ecosystem structure and function is generally a product of interactions between its different components. In the extreme arid environmental conditions of arid lands these interactions are of high significance, so that slight irregularities in one component of the ecosystem are likely to lead to substantial variations in others, so creating distinct micro habitats.

Invasion of Nypa palm into mangroves is a problem in the Cameroon Estuary. Soil variability is one of the dominant features that support Nypa palm establishment. The objective was to characterize the soil under the different mangrove stands; Purely Nypa palm stands (A), mixed stands i.e Nypa palm and other mangrove species (B) and other mangrove species i.e Nypa palm free (C), determine the principal soil characteristic critical for Nypa spread. 9 plots of 20 x 20 m were laid in each of the sites. 27 soil samples were collected in the North, West, South East and Center at a depth of 30 cm in these three sites using a soil auger. The results in the three sites indicated that; soils were acidic (3.87- 4.39), pH values did not significantly differ (alpha >0.05), organic matter was low in A (12.32%) and B (16.35%).Soil Organic Carbon ranged from (4.52 to 7.06%). High percentage of organic carbon content was recorded in C (7.06%). Low percentage of organic carbon was found in A (4.52%). Total nitrogen varied from 1.04 g/kg, 1.70g/kg, 1.80 g/kg in sites C, A and B. In all the mangrove stands, the values of Exchangeable Ca content were below 4.0 cmolkg-1. Soil texture in the three sites were; sandy, clay and silt. Power test showed no significant different in soil types between the three sites (p>0.05). According to the component matrix the factor is positively loaded by soil EC, moisture content, organic matter, organic carbon, N, C/N, CEC, Ca, Mg, K, Na, Clay, Silt, and negatively loaded by the percent sand. This study therefore, suggests that since soil plays key role in Nypa palm establishment, there should be constant monitoring of soil quality to forestall drastic changes that will jeopardize the survival of the mangroves. Nypa palm seedlings should also be physically removed from mangrove forest to prevent colonization. In addition, more mangrove seeds should be planted in deforested mangrove areas to close the window of opportunity for the palms.
