“…The clay content for Lds was significantly higher than that for other land types. According to the content of each fraction in soils, Lss, U, and Lg were classified as silt loam (SiL), and Lds was classified as silty clay loam (SiCL), which were consistent with a previous study (Tsujimoto et al 2013). According to Hatta et al (2010), kaolinite is the dominant clay mineral in the soils of the ZFP due to the high weathering that results in less holding capacity for water and nutrients.…”

“…In this region, Yamamoto et al (2012) developed a method of assessing flood probability in order to select suitable areas where water for rice farming can be obtained naturally. Tsujimoto et al (2013) showed that seasonal flooding played a crucial role in the N-supplying capacity of soil on the floodplains, and this capacity was quantitatively predicted as a logarithmic function of the distance from a main river. In this study, we aimed to identify the suitable areas for rice cultivation by evaluating the characteristics of soil in the floodplains of SSA.…”

This study aimed to identify suitable areas for rice cultivation by evaluating the soil characteristics of underdeveloped land in Sub-Saharan Africa. Two transect lines were set on the Zaw floodplain (ZFP) along the White Volta River in the Northern Region of Ghana for a detailed survey on land types and soil sampling. Land types identified along the transect lines were upland (U), lowland grass (Lg), lowland shallow swamp (Lss), and lowland deep swamp (Lds). The soil texture for U, Lg, and Lss was classified as silt loam (SiL), while Lds was classified as silty clay loam (SiCL). Soil pH (H2O) was above 6 for U and Lg, and below 6 for Lss and Lds. Extractable S and available Zn were significantly greater in Lds than in other land types. Available Cu, Mn, Ni, and total nitrogen (T-N) were significantly lower in U, and total carbon (T-C) was significantly greater in Lds than in other land types. Factor analysis indicated that Lds had better soil fertility and sulfur availability than other land types. However, it seemed unsuitable for rice production due to deep water depth during the rainy season. Although Lss seemed to be relatively less suitable than Lds due to low soil fertility and low sulfur availability, the water depth in Lss was not as deep as in Lds. Access to a water source was easier in Lss than in Lg; thus, the Lss land type was considered comparatively suitable land for rice production in the study area. Nevertheless, the result implies that soil fertility and sulfur could be constraints, thereby requiring the proper application of fertilizer.Discipline: Watershed and regional resources management Additional key words: Soil fertility, sulfur deficiency, food security, Tamale

“…Homma et al (2003) showed that relative elevation is an important factor determining spatial variation in SOC and clay in a mini-watershed in Northeast Thailand. Tsujimoto et al (2013) also found that soil TC content showed significant correlation with elevation and distance to the reservoirs in a floodplain of the White Volta River in the Northern Region of Ghana. However, they could not adequately explain the cause of large variations in soil TC content among locations close to water reservoirs, ranging from around 5.0 to 40.0 g , by using such topography data as elevation, slope, etc.…”

“…Such a large variation in SOC or soil TC content is not limited to the regional scale. Tsujimoto et al (2013) focused on a narrower area of a few square kilometers that included a floodplain of the White Volta River in the Northern Region of Ghana, and found that floodplains had higher soil TC content, with a maximum of 40.2 g kg . However, the factors causing spatial variation of soil TC content in a small area of a floodplain have not been well studied.…”

Agricultural fires in the southeastern U.S. during SEAC⁴RS: Emissions of trace gases and particles and evolution of ozone, reactive nitrogen, and organic aerosol

et al. 2016

View full text Add to dashboard Cite

Emissions from 15 agricultural fires in the southeastern U.S. were measured from the NASA DC‐8 research aircraft during the summer 2013 Studies of Emissions and Atmospheric Composition, Clouds and Climate Coupling by Regional Surveys (SEAC4RS) campaign. This study reports a detailed set of emission factors (EFs) for 25 trace gases and 6 fine particle species. The chemical evolution of the primary emissions in seven plumes was examined in detail for ~1.2 h. A Lagrangian plume cross‐section model was used to simulate the evolution of ozone (O3), reactive nitrogen species, and organic aerosol (OA). Observed EFs are generally consistent with previous measurements of crop residue burning, but the fires studied here emitted high amounts of SO2 and fine particles, especially primary OA and chloride. Filter‐based measurements of aerosol light absorption implied that brown carbon (BrC) was ubiquitous in the plumes. In aged plumes, rapid production of O3, peroxyacetyl nitrate (PAN), and nitrate was observed with ΔO3/ΔCO, ΔPAN/ΔNOy, and Δnitrate/ΔNOy reaching ~0.1, ~0.3, and ~0.3. For five selected cases, the model reasonably simulated O3 formation but underestimated PAN formation. No significant evolution of OA mass or BrC absorption was observed. However, a consistent increase in oxygen‐to‐carbon (O/C) ratios of OA indicated that OA oxidation in the agricultural fire plumes was much faster than in urban and forest fire plumes. Finally, total annual SO2, NOx, and CO emissions from agricultural fires in Arkansas, Louisiana, Mississippi, and Missouri were estimated (within a factor of ~2) to be equivalent to ~2% SO2 from coal combustion and ~1% NOx and ~9% CO from mobile sources.
