Physical properties of a Mollisol, an Oxisol and an Inceptisol
Soil and Tillage Research, 1990Abstract An Inceptisol (Andept) from Ecuador, an OOxisol (Ustox) from Columbia and a Mollisol (Udoll) from the U.S.A. were studied. The clay in the Andept was >85% amorphous with allophane being predominant. The Ustox contained sesqui-oxides of iron and aluminum and kaolinite, while the Udoll contained hydrous mica, quartz and kaolinite in the clay ...

Extractable aluminium in New Zealand Andisols and Inceptisols
Geoderma Regional, 2020Abstract It is critical to have a soil test that allows for the measurement of potential toxicity. A laboratory experiment was undertaken to investigate the effects of changing the concentration of salt in the extract and extraction time of the standard CaCl2 and KCl soil Al tests on the Al concentrations extracted from 13 soils from four New Zealand

1983
Publisher Summary The concept of Inceptisols is essentially two fold, that is (1) those soils that have undergone some modification of the parent material but not to the extent that diagnostic horizons such as spodic, argillic, or oxic have formed and (2) soils that do not adequately fit into any other soil order. Some have termed Inceptisols as the “

Phosphate Fractions in Calcareous Vertisols and Inceptisols of Spain
Soil Science Society of America Journal, 1989Abstract Calcareous Vertisols and associated Inceptisols are abundant around the River Guadalquivir Valley, southern Spain. They support a profitable rainfed agriculture; little is known, however, about their phosphate status and fertility.

“Chloritized” Vermiculite and Smectite in some Inceptisols and Spodosols
Soil Science and Plant Nutrition, 1987“Chloritized” vermiculite and smectite in the B horizons of two Inceptisols derived from volcanic ash and two Spodosols were studied by a combination of methods. The “chloritized” minerals did not expand with Mg- or Ca-saturation and glycerol solvation and did not collapse upon K-saturation and heating at 300°C after treatment with dithionite-citrate ...

CHARGE CHARACTERISTICS OF AN OXISOL AND AN INCEPTISOL FROM HAWAII
Soil Science, 1975ABSTRACTPotentiometric and counter-ion adsorption techniques were used to study the effects of pH, electrolyte concentration, and phosphate treatment on charges associated with a Typic Gibbsihumox and a Typic Hydrandept.

Phosphate Sorption by Calcareous Vertisols and Inceptisols of Spain
Soil Science Society of America Journal, 1989Abstract The study of phosphate sorption by soils has practical interest but little is known on the quantitative importance of phosphate sorption by Vertisols and the soil properties affecting it. In this study we examined phosphate sorption by 24 samples of calcareous Vertisols and associated Inceptisols of ...

Repeated Bray‐2 extractions of an Inceptisol and an Andisol
Communications in Soil Science and Plant Analysis, 1999Abstract Bray‐2 extractable phosphorus (Bray2‐P) is commonly used to measure plant‐available P in soil. The pool size of extractable P in the residual soil should be reduced after extraction. Phosphorus, once released with the Bray‐2 solution, is resorbed by the soil during the extraction‐filtration period.

Humic acid and fertilizers on nutrition of rice in an Alfisol and Inceptisol
Madras Agricultural Journal, 2004To study the fertilizers and humic acid on nutrient uptake in Alfisol and Inceptisol, two field experiments were conducted during rabi 2001 with various levels of fertilizers and humic acid treatments. A large increase was recorded in the uptake of nutrients for the application of humic acid (HA) upto 40 kg ha'.

ZINC ADSORPTION IN VERTISOLS AND INCEPTISOLS OF TAMIL NADU
Madras Agricultural Journal, 1991Zinc adsorption in sixteen surface soil samples of Vertisol and Inceptisol was studied over a wide range of zinc solution concentrations (2.5 to 200 ppm). The zinc adsorption data conformed to Freundlich equation for the entire range of concentration tested. The Freundlich constants 'k' and 'n' were derived for zinc in these soils.
