Conventional wisdom has it that the friability of clay soils and their slaking behavior is dependent on their organic matter content, and the consequential penetration resistance is an indication of the plant available soil for optimum root development.
Increasing plant available water with the appropriate hydraulic conductivity to mobilize irrigation water and nutrients is therefore one of the most critical consideration of any fertigation program.With today's advancements in precision agriculture and the reliance of liquid fertigation systems, the mechanical deployment of large volumes organic matter as well as powders of gypsum or lime can be somewhat problematic.
The CHT alternative mechanism, which is the subject of this website, can be seen at work in the attached chart, notice the arresting of the slacking behavior and the consequent retention of water with the soil. The full presentation can be found here. (28 pages)
Detailed reporting of CHT's fertigation deployed soil conditioners to influence slaking behavior maybe found below:
The robustness of the application of CHT soil ameliorants can also be seen, in the video below, demonstrating that overcoming consolidation and reducing penetration resistance will lead to increase infiltration, less water logging and better root growth.
