“…Al ox ranges from 0.54 cmol c kg À1 in a subsoil horizon to 2.02 cmol c kg À1 in an organic soil horizon. The sizes of the Al-pools in the soils in the two catchments are in the same range as in the acidic forest soils in Chongqing and Guiyang (Liao et al, 1997) and in acidic forest soils in Europe and North America (Berggren and Mulder, 1995;Koptsik and Koptsik, 1995;Koptsik and Silaeva, 1996). The concentration of exchangeable Fe is low, which may limit the availability of this important plant nutrient (Wang et al, 1989).…”

Distribution of Al-, Fe-and Mn-pools was investigated in five forest soil profiles (consisting of four horizons) in each of two Hunan catchments (BLT and LKS) where acid deposition has been considered critical. Al-and Fe-pools were higher in BLT than those in LKS, but Mn-pools much lower in BLT. Mn-pools vary from topsoils to bottom soils, but there are different trends for different Mn speciation. Al-and Fe-pools, except amorphous Fe ox , were positively correlated to contents of soil organic matter (OM) showed by the loss on ignition in the two catchments. Accumulation of Al-and Fe-pools may occur in the area where soil organic matter was enriched (e.g. in top soil and rhizosphere soil). However, no direct correlation is observed between Mn and OM. Acidic atmospheric deposition may affect transforming among speciations of Al-, Fe-and Mn-pools and leaching of soil Al, Fe and Mn through formation of soluble organometal dissolved Al which was potentially toxic, increased. There were significant correlations between Al-pools complexes or change of oxidation-reduction conditions. Mn ex (exchangeable Mn) and Mn ox (amorphous and organic Mn) were highly linearly correlation with soil pH values at LKS but at BLT. Under acid deposition, the availability of the nutrient Fe increased with the amount of dissolved Al, which was potentially toxic, in the two catchments. There are no significant correlations between Al ex (exchangeable Al) and Mn ex , Fe ex (exchangeable Fe) and Mn ex in this work, indicating potentially toxic Mn increase seldom accompanying with Al increase in the two catchments.

“…concentrations. Release of Al 3+ is an important acid buffering process in acid soils (Mulder et al, 1989;Berggren & Mulder, 1995;Larssen et al, 1999). Considering the depletion of base cations from the soil complex under N treatments (Fig 5a), a consequence of elevated H + production (low pH) is the dissolution of Al from soil (van Breemen et al, 1983;Schulze, 1989;Krusche et al, 2003).…”

Elevated anthropogenic nitrogen (N) deposition has greatly altered terrestrial ecosystem functioning, threatening ecosystem health via acidification and eutrophication in temperate and boreal forests across the northern hemisphere. However, response of forest soil acidification to N deposition has been less studied in humid tropics compared to other forest types. This study was designed to explore impacts of long-term N deposition on soil acidification processes in tropical forests. We have established a long-term N deposition . We measured soil acidification status and element leaching in soil drainage solution after 6-year N addition.Results showed that our study site has been experiencing serious soil acidification and was quite acid-sensitive showing high acidification (pH (H2O) <4.0), negative water-extracted acid neutralizing capacity (ANC) and low base saturation (BS,< 8%) throughout soil profiles.Long-term N addition significantly accelerated soil acidification, leading to depleted base cations and decreased BS, and further lowered ANC.

“…Nonetheless, the levels of soil organic matter in all the agro-ecological zones were low. The low soil organic carbon content could be due to rapid decomposition of organic matter promoted by the prevailing high temperatures and high humidity [42], and continuous cropping without the return of crop residues to replenish the soil organic C stock [43]. The slightly low soil pH may be attributed to continuous cropping and leaching of soil basic cations [44].…”

The study was conducted to assess the influence of different agro-ecological zones and cropping seasons on the incidence and severity of maize streak disease (MSD) in Ghana. Field surveys were conducted in two districts each of the coastal savannah, forest, and transitional agro-ecological zones of the Volta region to assess the incidence and severity of MSD in farmers' fields, during the 2014 minor and 2015 major cropping seasons. The disease assessment was carried out in 12 fields from each district, and for each field on both maize plants growing under tree shade and in open parts of the field. The plants were scored for disease severity based on a 1-5 visual scale (1=no infection and 5=very severe infection). Percentage total N, available P, exchangeable K, organic matter levels and pH were determined from soil samples collected from each of the fields surveyed. Incidence and severity of MSD on maize plants growing under tree shade and in open parts of the fields were significantly higher (P<0.05) in the transition zone than in the forest and coastal savannah eco-zones during the 2014 and 2015 cropping seasons. Mean incidence and severity of MSD on maize plants growing under tree shade were significantly higher than those in the open part of the fields in both cropping seasons. The levels of MSD incidence and severity recorded in 2014 were significantly higher (P<0.05) than 2015. Low levels of soil total N, available P, exchangeable K and organic carbon were detected across the three agro-ecological zones. Incidence and severity scores of MSD were significantly and negatively correlated with soil total N, available P, exchangeable K and organic matter (P<0.01). In conclusion, MSD incidence and severity vary with the cropping seasons and agro-ecological zones and are partly affected by low soil fertility levels and tree shades.
