Geomatics-based mapping of hydraulic soil properties for agricultural management

Abstract EN

Soil water is one of the most important information as input to land surface, ecological and hydrological models.

Reliable soil water information with current coverage in the area is needed for proper cultivation management.

A number of 460 soil profiles data were evaluated for the performance of estimates inverse distance weighting to map some of the soil quality properties.

Maps with the investigated coverage were produced with the soil information available about soil texture and organic matter.

It was observed from the results that increasing the number of soil profiles to cover the area in detail helped to overcome its unknown reliability.

The results also demonstrated that hydraulic properties of field soils can improve predictions for such models using remote sensing data.

A reliable soil water map can serve multiple purposes, including scientific research and application of models on different geographical scales.

It is also essential for the development and spatial implementation of a comprehensive soil quality (SQ) indicator planned by the investigated study.
