Soil reengineering is a process that involves the redesign of soil profiles to improve the conditions for crop growth. This can include adding organic and inorganic soil improvers, adjusting soil pH, and improving soil structure to enhance water retention and nutrient availability. The goal is to create a more favourable environment for plant roots to access water and nutrients. Soil reengineering has been shown to potentially double grain yield and water use efficiency, especially in favourable seasons. However, the long-term sustainability and economic returns of these improvements are still key questions being investigated by researchers.
