However, manure application rates can be reduced with the use of N fertilizer in topdressing.
The aim of this study was to evaluate crop responses to different application rates of animal manure sources, used alone and supplemented with mineral N topdressing, in a no-tillage system.
The study was carried out from 2005 to 2008 on a Hapludalf soil.
The treatments consisted of rates of 10, 20 and 30 m3 ha-1 of pig slurry (PS), and of 1 and 2 t ha-1 of turkey manure (TM), applied alone and supplemented with topdressed N fertilizer (TNF), as well as two controls, mineral fer...
