Evidence of a plant genetic basis for maize roots impacting soil organic matter mineralization
نویسندگان
چکیده
Maize root traits associated with soil organic matter (SOM) mineralization were demonstrated to have a heritable genetic basis. We show length, diameter and cumulative root-derived C be strong predictors of SOM-C identify two candidate genes enhanced rates. There is potential target these enhance release nutrients from SOM support crop nutrition within sustainable maize cropping systems.

Effect of Living Roots on Soil Organic Matter Decomposition
Published information is contradictory about the inhibitory or stimulatory effect of living roots on soil organic matter d~m~sition. In this study, i4C-labelled rye straw was exposed in fertilii or unfertilized soil with or without plants (winter rye, Se&e cereuIe) for 49 days under semi-controlled conditions. Our objective was to study the effect of roots on soil organic matter mineralization ...
متن کاملRyegrass - derived pyrogenic organic matter changes organic carbon and nitrogen mineralization in a temperate forest soil
Pyrogenic organic matter (PyOM) is considered as a technique to improve soil fertility and store carbon (C) in soil. However, little is known regarding soil organic C and nitrogen (N) mineralization in PyOM-amended soils. To investigate the relationship between the C and N mineralization rates and the possible consequences in terms of C storage and N availability, we incubated ryegrass-derived ...
متن کاملCarbon mineralizability determines interactive effects on mineralization of pyrogenic organic matter and soil organic carbon.
Soil organic carbon (SOC) is a critical and active pool in the global C cycle, and the addition of pyrogenic organic matter (PyOM) has been shown to change SOC cycling, increasing or decreasing mineralization rates (often referred to as priming). We adjusted the amount of easily mineralizable C in the soil, through 1-day and 6-month preincubations, and in PyOM made from maple wood at 350 °C, th...
متن کاملSoil organic matter and management of plant-parasitic nematodes.
Organic matter and its replenishment has become a major component of soil health management programs. Many of the soil's physical, chemical, and biological properties are a function of organic matter content and quality. Adding organic matter to soil influences diverse and important biological activities. The diversity and number of free-living and plant-parasitic nematodes are altered by rotat...
متن کاملOrganic matter turnover in soil physical fractions following woody plant invasion of grassland: Evidence from natural
Soil physical structure causes differential accessibility of soil organic carbon (SOC) to decomposer organisms and is an important determinant of SOC storage and turnover. Techniques for physical fractionation of soil organic matter in conjunction with isotopic analyses (dC, dN) of those soil fractions have been used previously to (a) determine where organic C is stored relative to aggregate st...
