Crop Residues in Wheat-Oilseed Rape Rotation System: a Pivotal, Shifting Platform for Microbial Meetings

Nitrogen Fertilizer Management for Enhancing Crop Productivity and Nitrogen Use Efficiency in a Rice-Oilseed Rape Rotation System in China

The use of efficient rates of nitrogen (N) fertilizer application is important with regard to increasing crop productivity and maintaining environmental sustainability. Rice-oilseed rape rotations are a mainstay of the economy and food security of China. Therefore, a field experiment was carried out during 2011-2013 in Honghu to identify the most appropriate N application rates for enhancing cr...

Impact of Shortened Crop Rotation of Oilseed Rape on Soil and Rhizosphere Microbial Diversity in Relation to Yield Decline

Oilseed rape (OSR) grown in monoculture shows a decline in yield relative to virgin OSR of up to 25%, but the mechanisms responsible are unknown. A long term field experiment of OSR grown in a range of rotations with wheat was used to determine whether shifts in fungal and bacterial populations of the rhizosphere and bulk soil were associated with the development of OSR yield decline. The commu...

Crop Rotation Effects on Soil Microbial Populations, Biomass and Diversity under Wheat in a Brown Loam

The inclusion of grain and green manure (GM) or forage legumes in cereal production systems on the Prairies does improve the fertility and quality of soils (Wright 1990; Campbell et al. 1992; Green and Biederbeck 1995; Biederbeck et al. 1998). Legume-based cropping systems can also reduce nitrogen losses and greatly increase the proportion of crop residuecarbon that is sequestered in stable soi...

Urea and ammonium nitrate as sources of N for wheat,sugarbeets and chickpeas in A 3-year crop rotation

Crop Establishment Practices Are a Driver of the Plant Microbiota in Winter Oilseed Rape (Brassica napus)

Gaining a greater understanding of the plant microbiota and its interactions with its host plant heralds a new era of scientific discovery in agriculture. Different agricultural management practices influence soil microbial populations by changing a soil's physical, chemical and biological properties. However, the impact of these practices on the microbiota associated with economically importan...
