“…In the lower trough, a somewhat more evolved profile of dark and black chroma (10YR 3/1), A1 AC1g C1g horizon sequence and Gleyc Arenosol morphology (COL-3) (FAO, 2015) is developed, which mainly supports grasses (Agrostis The soil profiles have been described and classified according to the standards of FAO (1977) and FAO (2015). The color was determined following the Munsell scale (Munsell, 1990), pH according to Guitián and Carballas (1976) and electrical conductivity (EC) according to USDA (1973) and Duchaufour (1975).

The wetlands on the quartz sands aeolian sheet make up one of the ecosystems most recognized and important of the Doñana National Park and Doñana Biological Reserve (South Spain). More than 650 temporal small-lakes have been surveyed in the abundant sand depressions of the aeolian sheet, the most are a hydro-geomorphological dune-small-lake system. This paper studies the pedological processes around Colón small-lake ecosystem wetland (COL), one of the more interesting temporal small-lakes. The movement of fine particles through sand dunes ("sand washing") and their subsequent accumulation in depth is the process responsible for the formation of a large part of the small and medium small-lakes in the Eolian Litoral Sheet of Doñana. Their bodies of water are supported by these clay layers generated corresponding sometimes to ancient soil horizons formed under previous different ecological conditions. The vegetation, the soil morphology and the evolution of the physical-chemical processes studied in this geosystem small-lake of Colón allow understand this phenomenon of chronologies very recent.

“…properties were analyzed: soil organic carbon (SOC), determined using a calcination method [7]; texture, determined using a diffraction laser [8]; pH (potassium chloride -KCl), determined using ISO methodology 10390:2005 (ISO 10390:2005). The amounts of Pb and Cu were measured by flameless atomic absorption spectroscopy (detection limits for Pb = 0,5 mg/g and for Cu = 0,1 mg/kg), and Hg was measured by flame atomic absorption spectroscopy (detection limits for Hg = 0,1 mg/kg).…”

“…Soils from the control and apple mint pots corresponding to 9 and 30 DAI were air-dried and sieved through a 2 mm mesh for physicochemical analyses. Soil pH was measured using 2:1 water/soil extracts [40]. Organic matter was determined using a muffle furnace (ELF 11/14B, Carbolite Gero Ltd., Hope Valley, UK) at 360 • C for 3 h. The cation exchange capacity (CEC) and exchangeable cation contents were determined according to Peech et al [41].…”

The need to find alternatives to synthetic herbicides has led to the evaluation of the use of allelopathic biomass from different agroforestry species as soil amendments for weed control. Mentha suaveolens Ehrh. (apple mint) could be a suitable candidate as an ecoherbicide due to its availability in the agroecosystem, well-studied biological activities, and known chemical composition. For the present study, two greenhouse pot experiments were conducted by incorporating flowering aerial biomass of apple mint into the soil. In the first one, the potential phytotoxic effects of M. suaveolens at doses 1 and 2% were evaluated on the germination and growth of maize and its accompanying weeds. In a second temporary assay, the duration of phytotoxicity and the effects of apple mint (0.5% dose) on the physicochemical properties of the soil were elucidated. The soluble (phenolics and organic acids) and volatile compounds potentially releasable from the allelopathic biomass were identified. The apple mint exerted adverse effects on the germination and growth of dicotyledonous weed species, especially Amaranthus retroflexus and Solanum nigrum, with almost 100% inhibition, as well as on the growth of monocotyledonous weeds such as Digitaria sanguinalis, with a reduction of more than 95%. On the contrary, maize yield and soil properties pH, CECe, organic matter, and exchangeable cations were improved by the ecoherbicide. Chemical analyses of apple mint aerial biomass revealed the presence of 7 phenolic compounds, 9 organic acids, and 32 volatiles. For this study, the effects of incorporating M. suaveolens aerial biomass into soil were evaluated for the first time, and it was demonstrated that it has potential as an eco-friendly plant-based tool for Integrated Weed Management.
