Silicophytoliths from a Pampean native tree community (Celtis ehrenbergiana community) and their representation in the soil assemblage por De Rito, María Victoria, Fernández Honaine, Mariana, Osterrieth, Margarita, Morel, Eduardo

“…Soilsilicophytoliths were counted and described, and their abundances were referred in relation to total soil mineralogy.Morphologies were similar between species and were mainly derived from the epidermal, vascular andsclerenchymatic tissues. …”

Managing soil organic carbon in tropical agroecosystems: evidence from four long-term experiments in Kenya por Laub, M., Corbeels, Marc, Couedel, A., Ndungu, S.M., Mucheru-Muna, M., Mugendi, D., Necpalova, M., Waswa, W., Broek, M. van de, Vanlauwe, Bernard, Six, Johan

“…The relative annual change of SOC contents showed a higher site specificity in farmyard manure, Calliandra and Tithonia treatments than in the control treatment, suggesting that the drivers of site specificity in SOC buildup (soil mineralogy, soil texture, climate) need to be better understood for effective targeting management of organic resources. …”

Exploring the West African forest island phenomenon: scientific insights gained, successes achieved and capacities strengthened por Logah, V., Azeez, J., Compaore, H., Mesele, S.A., Ocansey, C.M., Bougma, A., Tetteh, E.N., Veenendaal, E.M., Lloyd, J.

“…Our results showed that the forest islands do not differ significantly from the adjoining ecosystems in soil mineralogy implying that their formation was anthropogenically driven. …”

Critical bulk density for a Mollisol and a Vertisol using least limiting water range: effect on early wheat growth por Wilson, Marcelo German, Sasal, Maria Carolina, Caviglia, Octavio

“…These findings provide an interesting platform for the management of soils with similar textural classes and different clay mineralogy, particularly when they are present in the same paddock across the landscape.…”

Nutrient management por Haque, I., Abebe, M., Mamo, T., Dibabe, A.

“…Due to their high moisture- storage capacity, they have high production potential and this potential remains underutilised because of the difficulty of managing these soils. This paper summarises available information on chemical properties, N, P and mineralogy. …”

Maize response to macronutrients and potential for profitability in sub-Saharan Africa por Kihara, Job Maguta, Huising, Jeroen, Nziguheba, Generose, Waswa, Boaz Shaban, Njoroge, S, Kabambe, V., Iwuafor, E., Kibunja, C.N., Esilaba, Anthony O., Coulibaly, A

“…Chances for profitability are highest when soil organic carbon is 1–2 % and control maize grain yield is 1–3 t ha−1 but also depends on relatively static soil properties (primarily texture and mineralogy) that are not under farmer control. …”

Capacidad de intercambio catiónico en suelos de cenizas volcánicas recientes por Guerrero, Jose I., Bornemisza, Elemer

“…Very low CEC was observed for the very recent surface soils which increased for subsoils. The more developed soils showed the contrary tendency Air drying reduced CEC when determined with Na, but it was little affected, when divalent cations were used Organic matter destruction has a variable effect on the CEC of the studied samples probably due to their variable mineralogy. …”

Adsorcao de nitrato em Latossolos sob vegetacao de cerrado por Velloso, Ary Carlos Xavier

“…At given pH, adsorption was concentration-dependent in a manner consistent with the Langmuir equation In soils with similar chemical and mineralogical compositions in the Ap and B horizons, the lower nitrate adsorption of the Ap horizons was attributed to the dif-ferences in the organic matter content To determine the nitrate vemaining in the supernatant liquid, the nitrate elec-trode method and the spectrophotometric method using the ultraviolet range (200 mm) were used, which were checked against the phenoldisulfonic method.…”

Pores size distribution and pores volume density of mollisols and vertisols under different cropping intensity managements with no - tillage por Behrends Kraemer, Filipe, Castiglioni, Mario Guillermo, Morras, Héctor José María, Fernández, Patricia, Alvarez, Carina

“…Pore parameters were related to management variables, to clay mineralogy and to several soil physical and chemical properties allowing to i) evaluate the effects of cropping intensification on soil physical properties; ii) evaluate the effects of intrinsic and dynamics factors on the behaviour of pore variable; iii) build an optimal pore size frequency curve to assess soil health. …”
