“…As observed previously by Cearreta et al (2002) and Fernández et al (2010), the main constituents of the sedimentary sequences in the salt marshes of the southern Bay of Biscay are detrital materials deposited from estuarine waters whereas organic materials from the vegetated surface are rapidly consumed during burial. Organic matter contents in the Busturia core were very low and exhibited a progressive decrease with depth, in accordance with previous studies in other regenerated and natural salt marshes from the same coastal area (Cearreta et al, 2002).…”

“…Recovering natural system dynamics must include the disturbances which cannot be controlled in initiating restoration, but must be considered when designing restoration projects. The changing pattern in soil nutrients of the reclaimed marsh is a result of the combined effects of drivers over time, such as wind, flooding, drought and rainfall (Fernandez et al 2010;Hung et al 2013). The effects of seawall reclamation on salt marsh and its soil environments might be reflected at various spatial and temporal scales.…”

“…Salt marshes that regenerated on abandoned land reclaimed by seawalls have been used, to certain extent, as natural analogues for salt marsh development. Particular attentions have been given to the succession of plant communities (Bakker et al 2002;Bozek and Burdick 2005;Wolters et al 2005;Garbutt and Wolters 2008) and restoration of soil nutrient pools, soil seed bank (Santin et al 2009;Fernandez et al 2010;Hung et al 2013;Zhang et al 2013;Bai et al 2014;Gilland and McCarthy 2014;Wang et al 2014). Those researches could provide general information on the design and management of coastal marsh restoration schemes (Garbutt and Wolters 2008).…”

Coastal salt marsh has been globally fragmented by man-made coastal seawalls. However, the dynamic changes in community structure and abiotic environments in these regenerated marsh after seawall reclamation are largely unknown. We analyzed the seasonal changes of soil nutrient pools and the direction effects on them. The results showed that soil total nitrogen (TN) has decreased but soil organic carbon (SOC) has increased from May to September. Direction has influenced the patterns and seasonal changes in soil TN and SOC. The potential influencing factors have been largely contributed to soil salinity reduction, vegetation growth, microorganism activities with different seasonal characteristics. Researches on seasonal dynamic of marsh regeneration after seawall reclamation can provide us helpful information to understand mechanism of marsh restoration and design coastal marsh restoration projects.

“…It has been an important regional practice to offset the negative impact of fast population growth and urbanization progress on farmland shortage [1][2][3]. However, the newly reclaimed coastal mudflat areas generally have brackish shallow groundwater table and high content of salt in the soils, which impede the growth of plants [4]. To make the soils suitable for crop production, land drainage is required to lower the water table and leach the soluble salts from the soil profile.…”

Experimental Study on the Potential Use of Bundled Crop Straws as Subsurface Drainage Material in the Newly Reclaimed Coastal Land in Eastern China

Initial land reclamation of the saline soils often requires higher drainage intensity for quick leaching of salts from the soil profile; however, drainage pipes placed at closer spacing may result in higher cost. Seeking an inexpensive degradable organic subsurface drainage material may satisfy such needs of initial drainage, low investment and a heathy soil environment. Crop straws are porous organic materials that have certain strength and endurance. In this research, we explored the potential of using bundled maize stalks and rice straws as subsurface drainage material in place of plastic pipes. Through an experimental study in large lysimeters that were filled with saline coastal soil and planted with maize, we examined the drainage performance of the two organic materials by comparing with the conventional plastic drainage pipes; soil moisture distribution, soil salinity changed with depth, and the crop information were monitored in the lysimeters during the maize growing period. The results showed that maize stalk drainage and the rice straw drainage were significantly (p < 0.05) more efficient in removing salt and water from the crop root zone than the plastic drainage pipes; they excelled in drainage rate, leaching fraction, and lowering water table; and their efficient drainage processes lowered salt stress in the crop root zone and resulted in a slightly higher level of biomass. The experimental results suggest that crop straws may be used as a good organic substitute for the plastic drainage pipes in the initial stage land reclamation of the saline coastal soils.
