Carl Luedecke originated from Saxony. After graduation as an agricultural engineer from the Agricultural Academy of Bonn-Poppelsdorf in 1882 he became Lecturer at the Agricultural Institute of Göttingen. In 1890, he was appointed cultural engineer of Hesse County in Mainz. Two years later, Luedecke gained the doctoral title from the Leipzig University. He was appointed associate professor of cultivation technology at Breslau University in 1897 and promoted to full professor there in 1920. Ferdinand Zunker (1885-1956) took over in 1923 as his successor.

Luedecke was an expert in the soil sciences and thus indirectly in hydraulics. His early works considered the soil and hydrologic conditions of the German Rhine Province and the Odenwald Region between the cities of Darmstadt and Kassel. In hydraulics, Luedecke was interested in the Cipolletti weir, an overfall structure introduced in the 1880s by Cesare Cipolletti (1843-1908). This weir has a trapezoidal front shape and should provide an almost linear increase of overflow depth with discharge. The Cipolletti weir was popular among agricultural engineers in the first decades of the 20th century, but actually has only historical relevance. Luedecke made further works on soil drainage and investigated the relationship between rainfall and runoff. He also proposed methods to drain Dutch marshlands and polders close to the Maas River. Luedecke was for a long time the Editor of the German journal Der Kuturtechniker, which was published from 1898 and disappeared only during World War II. Luedecke was the true motor of this relatively small journal, because of his constant supply of small notes on new machinery, on novel methods and on news in agricultural engineering.
