Phosphate Fractions in Calcareous Vertisols and Inceptisols of Spain

Soil Science Society of America Journal, 1989
Abstract 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, 1975
ABSTRACTPotentiometric 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, 1989
Abstract 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, 1999
Abstract 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, 2004
To 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'.

Role of Inceptisols in the Hydrology of Mountainous Catchments in Southeastern Brazil

Journal of Hydrologic Engineering, 2016
AbstractMantiqueira Range is the most important headwater region in southeastern Brazil, being responsible for streamflows that feed a significant part of Brazilian hydroelectric energy production. This region is extremely fragile with endemic species like those that compose the upper mountain cloud forest (UMCF), and the dominant soils are typical ...

Phosphorus Availability in Entisols, Inceptisols, and Mollisols of Iraqi Kurdistan

Soil Science, 2019
In this work, we investigated phosphorus (P) availability of three soil orders (Entisols, Inceptisols, and Mollisols) in the Kurdistan Region of Iraq. Addition of P fertilizers causes chemical and physical fixation of P due to the high amounts of calcium carbonate often present in the soils of this region.

ZINC ADSORPTION IN VERTISOLS AND INCEPTISOLS OF TAMIL NADU

Madras Agricultural Journal, 1991
Zinc 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.

Influence of Sugarcane Cropping on the Quality of an Oxisol and an Inceptisol in Mauritius

Communications in Soil Science and Plant Analysis, 2010
Productive capacity of Mauritius soils could be declining with sugarcane monoculture. Effects of short- and long-term sugarcane cropping on quality of an Oxisol and an Inceptisol were assessed to a depth of 50 cm. In the short term ( 50 years), OM and microbial biomass increased with inputs of crop residues, whereas exchangeable base levels improved in
