History
Before the LTE was established, soil management practices included wheat/soybean-maize rotation under no-tillage for more than 10 years.
Management
No-till since 1995.

Design period: Nutrient reposition and Sequences in soybean based rotations (2006—)

Design Type
Randomized complete block design
Design description
The LTE has six treatments. Each treatment corresponded to a cropping sequence-fertilization strategy combination, including soybean (Sy), wheat (Triticum aestivum L.) as a cover crop (CC), wheat for grain production crop, and maize (Zea mays L.), under no-tillage in a rainfed condition. Experimental plots are 5.3 m wide × 30 m long.
