Abstract
Salaojituskoetoiminnasta Suomessa
Highlights
50 % are tile drainage, 15 % nailed wooden case or bored wooden pipe drainage, while about 35 % are drained by other methods, which for the most part consist of brush drainage
10 % of the field area is nowadays cultivated without ditches: the total cultivated area drained with open ditches amounts to almost 2.000.000 ha., and the total length of the open ditches to at least 1.600.000 km
The increasing use of machines in field cultivation has made it urgently necessary to determine the best way to eliminate the disadvantages caused by open ditches
