- ... Numerous innovations in tillage systems have significantly altered agricultural production in North America. Mechanical, biological, and chemical innovations reduced labor requirements, increased yields and crop residues, and reduced pest impacts. Regional trends in tillage systems and equipment are the result of evolving design driven by soil, plant and climate factors that affect erosion, water ...

- ... Since CO(2) is a primary input for crop growth, there is interest in how increasing atmospheric CO(2) will affect crop productivity and alter cropping system management. Effects of elevated CO(2) on grain and residue production will be influenced by crop selection. This field study evaluated soybean [C3; Glycine max(L.) Merr.] and grain sorghum [C4; Sorghum bicolor (L.) Moench.] cropping systems m ...
