Brazil harvests two crops in the same year. Enter both—if you only grow one, leave the second one blank.
Open ditches do drain water, but they eat up the field: each channel takes up land that could be productive, blocks machine traffic, and is a hazard. Buried drainage returns the entire area to production—yielding two crops.
A machine stuck in mud means downtime, wasted diesel, and often the need to rent tracked equipment to finish planting or harvesting within the window. Add up the annual cost of this (for both crops).
The grain you never even get to harvest: the waterlogged patch where the harvester can’t go and the crop stays on the stalk, rotting. Direct loss, every rainy year.
The silent loss. Even where water does not rise to the surface, saturated subsoil deprives roots of air (without aeration, the plant cannot breathe or absorb nutrients) and disrupts soil temperature. The crop “doesn’t take off”—and that’s the extra yield that drainage restores.
Heavy rain right after planting rots the seed, forms a crust, and causes poor stand — and you replant. In poorly drained soil, this becomes routine in rainy years: you spend more on seed, delay the cycle, and push the harvest out of the window.
* The estimated investment is calculated by multiplying the cost per hectare by the total area. The actual amount varies depending on soil type, depth, and spacing—Techduto tailors the project to your specific area.
And the climate adds to the challenge. During El Niño, the South experiences excessive rain (and operations grind to a halt) while the Midwest/Mato Grosso faces drought. During La Niña, it’s the opposite: too much rain in the Midwest and drought in Rio Grande do Sul. Wherever you are, one of these two extremes will hit you—and in a year with too much water, all of the above goes through the roof. Drainage takes your crop out of this lottery.
Educational estimation tool. Results depend entirely on the values you enter and do not replace a technical design. Brazil has over 60 million hectares with potential for drainage (Embrapa); in floodplains and low-lying areas, subsurface drainage replaces open ditches, reclaims land, and restores the aeration that roots need.
