Practical approaches to prevent waterlogging in low-permeability fields.
Heavy clay soils present a unique challenge for agricultural drainage due to their low hydraulic conductivity. This article examines the key factors that influence drainage design in such conditions, including soil texture, compaction layers, and seasonal water table fluctuations. We discuss the role of envelope materials and proper spacing of drain lines to ensure long-term performance. Field observations from recent projects highlight common pitfalls and practical solutions for improving soil aeration and crop health.

Guide
A guide to measuring and forecasting groundwater levels for better irrigation planning.
Accurate water table monitoring is essential for understanding the dynamics of subsurface water flow and making informed drainage decisions. This post covers the installation and use of piezometers, data loggers, and remote sensing tools to track groundwater levels over time. We also explore how collected data feeds into predictive models that help farmers anticipate saturation events. Practical tips on sensor placement and data interpretation are included, based on our experience in regional farming estates.

Case Study
How electromagnetic induction and soil sampling reveal salinity hotspots.
Soil salinity is a growing concern in irrigated regions, and effective management starts with accurate mapping. This article compares traditional soil sampling with electromagnetic induction surveys, highlighting the strengths and limitations of each approach. We present case studies where salinity maps guided the placement of drainage systems and leaching programs. The results show significant improvements in crop productivity and soil health when salinity is addressed proactively.
