Grainews: Control drainage costly, but beneficial

Tiling can improve soil conditions, accelerate warming, boost crop growth and reduce nutrient runoff.

Tile drainage can significantly improve soil conditions by accelerating warming and reducing compaction, allowing farmers to access fields earlier in the season, according to a University of Manitoba expert.

Ranjan Sri Ranjan, a professor in the department of biosystems engineering at the University of Manitoba, says water needs five times more heat to warm up compared to dry soil — and the only source of energy to warm soil is the sun.
