Predicting soil phosphorus buffer coefficients using potential sorption site density and soil aggregation by Wang, X., Jackman, J.M., Yost, R.S., Linquist, B.A.

“…The use of clay as a predictor of the P buffer coefficient has been suggested for soils of similar mineralogy. However, it has not been satisfactory for soils with a wide range of soil mineralogies but relatively high clay content. …”

Spectroscopy and swelling soils: An integrated approach by Kariuki, P.C.

“…The potential of spectral data to discriminate the soils based on the clay mineralogy differences was thus concluded to show spectroscopy to have a potential at mapping swelling soils an assumption that was finally confirmed thr ough correlations between the spectral parameters and the established swelling pot ential indices. …”

Physical properties and moisture retention characteristics of some Nigerian soils by Lal, R.

“…Clay and sand contents are correlated with various soil moisture constants. The textural analysis may therefore be used to estimate moisture holding capacity at different suctions for these and similar soils with a predominantly uniform clay mineralogy, dominated by kaolinite and sesquioxides. …”

Short-term effects of agricultural practices on the soil structure and hydrodynamic in a deep tilled hardened sandy-silty volcanic–ash soil (cangahua) in Ecuador by Podwojewski, Pascal, Janeau, Jean L.

“…For these soils, no tillage and a permanent soil cover (pasture) would be the best agricultural option.…”

Genesis of subtropical soils with stony horizons in NE Argentina: Autochthony and polygenesis by Morras, Hector, Moretti, Lucas Martin, Piccolo, Gabriel Agustin, Zech, Wolfgang H.

“…In contrast, different analytical evidences, particularly the vertical and geographical variations in the SOM-stable carbon isotope ratios and the mineralogical composition of fine and coarse fractions, suggest that these red subtropical soils are polygenetic, being the result of a two-fold process linked to paleoecological fluctuations. …”

Replication Data for: Maize response to macronutrients and potential for profitability in sub-Saharan Africa by Kihara, Job Maguta

“…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. …”

Unravelling causes of poor crop response to applied N and P fertilizers on African soils by Sileshi, Gudeta W., Kihara, Job Maguta, Tamene, Lulseged D., Vanlauwe, Bernard, Phiri, Elijah, Jama, Bashir

“…However, the conditions under which non-responsiveness occurs, its underlying causes and its probability of occurrence on different soil types are not well understood. Using data from 542 sites and 14 soil types in 23 African countries, we provide novel insights into the linkage between lack of response to applied N, P and K, the mineralogy of soils and their resilience to erosion. …”

Storage of nutriments in black anthropogenic soils from the East-African Great Lakes Region by Delstanche, S., Asten, Piet J.A. van, Gaidashova, S.V., Delvaux, B.

“…We determined soil physico-chemical properties and total elemental contents, as well as soil mineralogical constitution.Typical black anthropogenic soils similar to the Amazonian Dark Earths (Terra Preta) occurred where banana cropping was ancient and soils benefited from frequent supply of organic manure and ash cooking residues. …”

Agricultural loess soils along a climosequence evidenced different susceptibility to acidification by simulated N-fertilization by Iturri, Laura Antonela, Buschiazzo, Daniel Eduardo

“…Thus, the Haplustolls were the less affected soils by acidification due to their high amount of free limeand soil organic matter (SOM) as well as the smectitic mineralogy of their fine mineral fractions, clay and silt. …”
