“…We observed an increase in the activities of enzymes involved in the degradation of labile C (CB, AG, BG) with the decrease in the aggregate size. This result is consistent with other studies that reported increased activity of enzymes involved in degradation of labile C with a decrease in aggregate size (Qin et al ., ; Lagomarsino et al ., ; Ling et al ., ; Nie et al ., ). On the other hand, the activity of NAG (i.e.…”

Soil carbon (C) stabilisation is known to depend in part on its distribution in structural aggregates, and upon soil microbial activity within the aggregates. However, the mechanisms and relative contributions of different microbial groups to C turnover in different aggregates under various management practices remain unclear. The aim of this study was to determine the role of soil aggregation and their associated microbial communities in driving the responses of soil organic matter (SOM) to multiple management practices. Our results demonstrate that higher amounts of C inputs coupled with greater soil aggregation in residue retention management practices has positive effects on soil C content. Our results provide evidence that different aggregate size classes support distinct microbial habitats which supports the colonisation of different microbial communities. Most importantly our results indicate that the effects of management practices on soil C is modulated by soil aggregate sizes and their associated microbial community and are more pronounced in macro-aggregate compared with micro-aggregate sizes. Based on our findings we recommend that differential response of management practices and microbial control on the C turnover in macro-aggregates and micro-aggregate should be explicitly considered when accounting for management impacts on soil C turnover.

“…Thus, SOM chemical fractionation techniques, combined with the natural abundance of stable C isotopes, have been considered effective approaches for quantifying SOM dynamics in agroecosystems (Dalal et al, 2013;Mazzilli et al, 2014;Wang et al, 2015). Black soils (Mollisols) have a large organic matter content, and are the most fertile and productive soils in northeastern China (Ling et al, 2014;Dou et al, 2016b). Recently, the productivity of Mollisols in China has been declining because of unsustainable agricultural practices (Xie et al, 2014).…”

Summary Agricultural measures that alter soil carbon (C) and nitrogen (N) dynamics might affect biogeochemical cycling. We combined soil chemical fractionation with isotope analyses to investigate C and N dynamics of soil organic matter pools (SOMP) after 25 years of cropping with the application of manure. Soil samples (0–20‐ and 20–40‐cm depths) were taken from the control (CK, i.e. the initial soil condition) and two cropping treatments: continuous maize (Zea mays L.) (MM) and maize–soya bean (Glycine max (L.) Merr.) rotation (MS). Samples were separated into recalcitrant and labile fractions and analysed for C and N content, δ13C and δ15N values, and soil C and N recalcitrance indices (RIC and RIN). Long‐term MM and MS cropping with manure application increased the soil organic carbon (SOC) storage considerably (1852.69 g C m−2 on average) because of enhanced recalcitrant C (RC) and labile C (LC). Soil organic nitrogen (SON) storage (166.79 g C m−2 on average) was also increased in MM and MS treatments from the accumulation of recalcitrant N (RN). In contrast, labile N (LN) was reduced in soil under MM and MS compared with CK. Storage of SOC was greater for MS than MM, but RIC was larger for MM than MS in the top layer, indicating that MM cropping might be more effective for future soil C sequestration because of the greater proportion of stable C stored. The RIN values were larger in cropped soil than in CK at 0–20‐cm depth. Moreover, the δ13C values indicated that the turnover rates of soil C were faster in MS than in MM. The more enriched δ15N values and decreased C:N ratios of SOMP occurred in soil under MM than under MS, indicating a greater loss of soil N with MM cropping. Highlights We investigated soil C and N dynamics under long‐term cropping combined with manure. We combined soil chemical fractionation with isotope analyses to determine C sequestration and turnover. Long‐term cropping increased recalcitrant C and N and labile C but decreased labile N. Continuous maize cropping would be better for stable C accumulation than maize–soya bean rotation.

El aporte de las hortalizas a la seguridad alimentaria y desarrollo económico de Colombia y la problemática ambiental mundial, justifica el interés de diseñar estrategias productivas sostenibles para la agrocadena. Se desarrolló un estudio para evaluar el efecto de la aplicación de aceites esenciales y agroinsumos en cultivos de ají, fríjol y berenjena en Codazzi, Cesar. La metodología comprendió el análisis de compatibilidad entre pesticidas utilizados en estas hortalizas, aceites de Lippia alba y Cymbopogon citratus, respecto al efecto biocida in vitro sobre cepas nativas de Macrophomina phaseolina, Phytophthora capsici y Colletotrichum gloeosporioides. En campo, se aplicó tiabendazol individual y combinado con los aceites. Se midieron indicadores fisicoquímicos y microbiológicos de suelo, incidencia de plagas y enfermedades y rendimiento de cultivos. Los aceites controlaron in vitro hasta el 97 % de fitopatógenos y exhibieron compatibilidad con carbendazim y tiabendazol. En campo, se observó control de enfermedades hasta del 67 % con C. citratus + tiabendazol respecto al testigo (P=0,00), rendimientos cercanos al promedio regional, mejores condiciones microbiológicas y fisicoquímicas del suelo. En conclusión, existen diferencias en el efecto edáfico entre tratamientos, fue más favorable la combinación de aceites y el agroquímico respecto al efecto individual de cada producto sobre las variables evaluadas. Lo anterior exhorta a continuar evaluaciones en campo con aceites para elucidar la duración de los efectos descritos.
