Changes in soil physical and chemical properties were evaluated in several on-farm studies located in rainfed, hardsetting red Al®sols (Ferric Luvisols) and in irrigated, self-mulching Vertisols (Chromic Vertisols) of eastern Australia. The objective of the studies was to evaluate changes in soil physical and chemical properties with time under commercial farming situations where changes had be...

Organochlorine pesticides (OCPs) such as DDT and DDE have been detected in the surface 0.2m of Vertisols in the lower Namoi Valley of north western New South Wales, Australia even though they have not been applied to crops since 1982. However, their presence in the deeper soil horizons has not been investigated. The objective of this study was to determine if OCPs were present to a depth of 1.2...

The sustainability of land management was assessed for a sugar cane plantation using soil Ž . chemical and physical properties as indicators. The plantation 6000 ha was established in 1979 on a broad alluvial plain and the majority of the soils are classified as Eutric and Mollic Fluvisols Ž . Ž . 73% and Eutric Vertisols 23% . Average annual rainfall is about 2000 mm with a dry season Ž from M...

considerable information exists in the literature showing that expansive layer silicates are not the only clay minerals present in vertisols. however, the presence of a very high clay content dominated by fine clay, regardless of the clay type, together with the wetting and drying cycle in the soil can also produce a high shrink-swell potential. we studied some vertisols with diverse parent mat...

Vertisols are important agricultural soils in the region. These soils are under various vegetables, sunflower and wheat cultivation. Fifteen soil sites were selected in this research. This research was carried out to determine background levels of total and DTPA extractable Fe, Mn, Zn, Cu, Ni, Cr, Pb, Co, and Cd with some important soil properties.

Hydrological monitoring is crucial to designing agricultural water management (AWM) interventions. This study characterizes the soil hydraulic properties of Alfisols and Vertisols develops rainfall-runoff-soil loss relationships through long-term hydrological monitoring. Two types landform techniques, i.e., raised bed flat bed, were followed in three paired watersheds 2–5 ha, characterized by d...

In the Senegal valley, it is commonly considered that the Acid Sulfate Soils of the delta are fossil soils overlain by more recent sediments, and that the Vertisols, which abruptly overlie a thick sandy horizon, result from a change in the sedimentation mode of the river. However, we show that both soils belong to the same pedological system extending from the delta to the limit of the last mar...

The aim of this investigation was to select effective Pseudomonas sp. strains that can enhance the productivity of soybean-wheat cropping systems in Vertisols of Central India. Out of 13 strains of Pseudomonas species tested in vitro, only five strains displayed plant growth-promoting (PGP) properties. All the strains significantly increased soil enzyme activities, except acid phosphatase, tota...

This study aimed to evaluate the effects of soil amendment and phosphorus fertilizer application techniques on chemical properties dry land Vertisols, P absorption efficiency by maize yield. The was conducted farmer's located in Noelbaki Village, Central Kupang District, Regency, East Nusa Tenggara, Indonesia. during two planting seasons, namely rainy season 2020/2021 (PS-1) 2021 (PS-2). used t...
