Effects of Continuous Sugar Beet Cropping on Rhizospheric Microbial Communities

Effects of different 3-year cropping systems on soil microbial communities and rhizoctonia diseases of potato.

ABSTRACT Eight different 3-year cropping systems, consisting of soybean-canola, soybean-barley, sweet corn-canola, sweet corn-soybean, green bean-sweet corn, canola-sweet corn, barley-clover, and continuous potato (non-rotation control) followed by potato as the third crop in all systems, were established in replicated field plots with two rotation entry points in Presque Isle, ME, in 1998. Cro...

Potential legacy effects of biofuel cropping systems on soil microbial communities in southern Wisconsin, USA

Soil microbial community structure is clearly linked to current plant species composition, but less is known about the legacy effects of plant species and agricultural management practices on soil microbial communities. Using microbial lipid biomarkers, we assessed patterns of community-level diversity and abundance at depths of 0-10 and 10-25 cm from three hay (alfalfa/orchardgrass) and two co...

Residual effects of sugar beet vinasse on plant growth

Residual effeet of a eoneentrated and depotassitied beet vinasse on growth and mineral eomposition of taH feseue (Festuca arundinacea) was studied. Results were compared with those obtained for a mineral fertilizer treatment and a control. Vinasse and inorganie fertilizer had been previously applied to two different soils at two rates for tive years. High doses of vinasse produeed the highest y...

Breaking continuous potato cropping with legumes improves soil microbial communities, enzyme activities and tuber yield

This study was conducted to explore the changes in soil microbial populations, enzyme activity, and tuber yield under the rotation sequences of Potato-Common vetch (P-C), Potato-Black medic (P-B) and Potato-Longdong alfalfa (P-L) in a semi-arid area of China. The study also determined the effects of continuous potato cropping (without legumes) on the above mentioned soil properties and yield. T...
