Notes
1) Only one entry phase for the six-year rotation.

Fertility treatments for maize/tomato and wheat systems include conventional mineral fertilizer, full organic fertilizer (manure + legume cover crops), and a winter legume cover crop without an additional N source. The wheat system also includes a wheat-fallow with no fertilizer added.

Wheat systems included irrigated vs. rainfed treatments.

Randomized Complete Design
Rotation treatments involve the presence and absence of a winter legume cover crop in a tomato-maize system or a wheat-fallow system. The tomato-maize system also tests organic and conventional fertility practices. The maize-fallow system also tests irrigation practices. There is an additional grassland system.

All systems were standard tillage except in 2003-2007, when maize/tomato systems were split into standard vs. reduced-tillage subplots.
