Controlled Traffic

Challenges for dryland farming on the Loess Plateau of China are continuous nutrient loss, low soil organic matter and crop yield, and soil degradation. Controlled traffic, combined with zero or minimum tillage and residue cover, has been proposed to improve soil structure and crop yield. From 1998 to 2006, we conducted a field experiment comparing soil organic matter and wheat productivity between controlled traffic and conventional tillage farming systems. The field experiment was conducted using 2 controlled traffic treatments (zero tillage with residue cover and no compaction, shallow tillage with residue cover and no compaction) and a conventional tillage treatment. Results showed that controlled traffic treatments significantly increased soil organic matter and microbial biomass in the 0–0.30 m soil profile. Controlled traffic with zero tillage significantly increased total N in the 0–0.05 m soil profile. The mean yield over 8 years of controlled traffic treatments was >10% greater than that of conventional tillage. Controlled traffic farming appears to be a solution to the cropping problems faced on the Loess Plateau of China.

Abstract. An overview of the land surface process field experiment series conducted in the Chinese Loess Plateau mesa region in 2004, 2005, 2006, 2007 and 2008 (abbreviated as LOPEX04, LOPEX05, LOPEX06, LOPEX07 and LOPEX08 hereafter) was presented. The general objectives of the experiment series, observations and preliminary results are summarized and presented in this paper. The research topics proposed by using the LOPEXs datasets are also prospected.
