Much of Texas’ wheat may be grazed as a part of a dual-use crop. But many fields are still prepared using conventional tillage, which may not efficiently capture rainfall — a key to economic success in a semi-arid environment, said a Texas AgriLife Research scientist. Dr. Paul DeLaune, environmental soil scientist at the Texas AgriLife Research and Extension Center at Vernon, said tillage operations can increase soil compaction, thereby increasing runoff.
