intercropping enhances productivity and maintains the most soil fertility properties relative to sole cropping. | yield and nutrient acquisition advantages are frequently found in intercropping systems. however, there are few published reports on soil fertility in intercropping relative to monocultures. a field experiment was therefore established in 2009 in gansu province, northwest china. the treatments comprised maize/faba bean, maize/soybean, maize/chickpea and maize/turnip intercropping, and their correspoding monocropping. in 2011 (the 3rd year) and 2012 (the 4th year) the yields and some soil chemica ... | 2014 | 25486249 |
