Abstract:
Particle size and free iron oxides content distribution along Sedimentary and Basement complex toposequences in South Western Nigeria was investigated. Representative soil samples totaling nine mini-pits (45 cm x 45 cm x 70 cm)  were taken based on topographic position. Conventional methods were used in the determination of pH, particle size distribution while the free iron oxides were determined using Dithionite-Citrate-Bicarbonate (DCB) and Acid Ammonium Oxalate methods. Results indicated that, soil texture was loamy sand surface horizon and increasing proportion of clay with depth, exc

Abstract:
Lowland rice in Lao PDR is predominantly grown under drought-prone, rainfed conditions in the wet season. We utilised a farmer participatory variety selection (PVS) approach in combination with multi-location yield trials (MLTs) conducted in high- and low-toposequence positions to test advanced breeding lines with the aim of improving the efficiency of the rice-breeding program and encouraging rapid adoption of improved lines. Upper position fields were utilised to screen for traits for unfavourable environments, including drought resistance, while lower fields were used to target yield potent

The pedological investigations were carried out on a soil toposequence of the semi-arid region on the basaltic landscape of western India and landform-soil relationship was established. In the study, seven soil profiles, representative of the summit, escarpment, lower pediment, undulating lands, plains and valley in a toposequence were studied. The study indicated that the soil development and its properties were following the toposequence. The profile development was least at the summit and best in the plains of the toposequence.

Abstract:
This study demonstrates the significant influence of toposequence position on soil properties and hydrological conditions, affecting crop yield. Variations in toposequence position lead to differences in soil properties; physical and chemical properties may vary minimally or maximally depending on the slope’s location. As slope increases, soil moisture and organic carbon rise, while bulk density, pH, and soil temperature decrease. Soils along a toposequence reveal that landscape position, erosion, aspect, and drainage impact soil depth, particle size distribution, and CEC. Understanding topogr

Abstract:
Drought is a major limiting factor for the production of rainfed rice in the Mekong Region. Thus, estimation of the length of growing period (LGP) based on estimation of the development of water deficit is essential for sound planning of agricultural development. A recently developed soil-water balance model was used to quantify the availability of water for rice crops and yield reduction due to water deficit. Field water availability is known to be largely affected by soil type and rainfall pattern, and their separate effects were investigated in this study of a spatial analysis of LGP, using

Rivers and streams are adversely affected by an increase in sedimentation in their waters from eroding land. High sediment loads in streams can bury fish eggs and prevent hatching, increasing nutrients in the water causing algae blooms, or even contaminating the water with heavy metals carried in or on the aggregates. The erodibility of soil is valuable knowledge to all land users so that we may predict soil loss and its potential to pollute streams. This is done by using the Revised Universal Soil Loss Equation (RUSLE). By predicting soil loss from a given landscape, land managers can take mi
