Effect of drainage systems in the water release rate in the process of drying wheat and corn grain

Basic aim of this research is to determine the influence of various types of pipe drainage upon water release rate in the process of drying wheat and corn kernel grown on a hydromorphic type of soil. The research was conducted a period of three years (1998-2001). Seven different types of drainage systems were built on pseudogleyic-gleyic soil (various clearances of drainage pipes with gravel used or not used in the drainage ditch above the pipes). Based on soil humidity measurement data (to the soil depth of 60 cm), acquired by means of gravitational method in the period of vegetation, it is clear that the most favorable humidity occurred on soil with drainage type A3-1 (clearances of drainage pipes being 25 meters, gravel used), with both cultures. The yield gained also shows that the most favorable drainage type is A3-1. The process of drying the kernel to the storage humidity value took the shortest time in the type A3-1. Results of this research contribute to energy savings in the process of drying wheat and corn crop. Additionally, the results can be used for selecting systems of drainage in dealing with excess water on hydromorphic soil types.
