Assessment of net primary productivity of maize (Zea mays L)‐based agroecosystems is
dependent on both above and belowground dry matter production that is ultimately returned …

Root-derived C influences soil microbial activities that regulate N transformations and
cycling in soil. The change in 13C abundance of soil microbial biomass was used to quantify …

Shoot to root ratios (S: R) at peak standing crop are commonly used to estimate the annual
crop residue C inputs to the soil from the root biomass left in the soil at harvest. However …

The transfer of photosynthate below ground by roots may be a major input to the soil C pool,
but is quantitatively the least understood, due to the technical difficulties associated with its …

Root traits are important to crop functioning, yet there is little information about how root traits
vary with shoot traits. Using a standardized protocol, we collected 160 soil cores (0− 210 cm) …

Root biomass is the most commonly studied root parameter to investigate below ground
crop response to environmental conditions and carbon cycling in agroecosystems. Root …

Crop residues are potential biofuel feedstocks, but residue removal may reduce soil carbon
(C). The inclusion of a cover crop in a corn bioenergy system could provide additional …

Background and aims In agroecosystems, carbon (C) inputs come from plant roots, retained
shoot residues and in some cases from applied manures. Manure and shoot derived C …

Root biomass is one of the most relevant root parameters for studies of plant response to
environmental change, soil carbon modeling or estimations of soil carbon sequestration. A …

In order to quantify rhizosphere respiration (Rrh) during the growing season, we monitored
the isotope ratio (δ13C) of soil CO2 in a corn (Zea mays L.) crop that was grown on a soil …
