Subsoil Manuring - A Viable Input Management Option for Improving Agricultural Productivity

Many farmers around the world struggle particularly during dry seasons with the tilth and aggregation in the clay subsoil, a new technology may significantly boost the soil's capacity to provide water to plant roots. The system of incorporating high rates of organic nitrogen-rich material into the upper layers of dense clay subsoils called Subsoil Manuring. Transformation of the subsoil's physical and chemical properties is most likely due to an increase in bacterial and fungal activity in the subsoil. Improving the physical properties in the subsoil enables the crop roots to enter and explore the clay and extract soil water in these layers - water that would otherwise not have been available to the crop.
