“…4). Similar retentions have been estimated for grain maize harvest residues in some experiments of comparable duration (Liang et al, 1998;Bolinder et al, 1999;Collins et al, 1999), while others (Angers et al, 1995;Clapp et al, 2000) reported that 21-37% of the residue input was retained in soil after 11-13 years of continuous maize. However, the retention of residue C in soil reported in the literature is often flawed by crude estimates of the amount of C returned in harvest residues, roots and stubbles.…”

The present experiment was designed (1) to allow the effect of soil type to be studied under identical weather conditions, eliminating any potential effects of soil-climate interactions on plant growth and C turnover in soil, and (2) to ensure that the various soils were under the same, well-defined management throughout the experimental period.…”

Silage maize has replaced fodder beet as energy-rich winter forage for housed cattle. In Denmark silage maize now occupies more than 4% of the arable land, but little is known on the effect of continuous silage maize on soil carbon dynamics under NW European cropping conditions. Soil total-C and natural 13 C abundance were determined every 2-3 years in four Danish arable soils (0-20 cm) continuously cropped to maize for 14 years under identical climatic conditions. A set of soils was sampled after 11 years with maize and analysed for total-C and maize-derived C in >2 mm plant residues, in <2 mm soil, and in 250-2000 m particulate organic matter (POM). Inputs of C in maize roots and stubbles induced an average annual increase in soil total-C of 90-470 kg C ha −1 . When soils were amended with an additional annual input of 8 t DM ha −1 in chopped above-ground maize biomass, soil C storage increased 110-940 kg C ha −1 per year. No changes in soil C/N ratio were observed. Carbon from maize roots and stubbles accumulated in the soil at an annual rate of 250-490 kg C ha −1 ; with an additional annual input of 8 t DM ha −1 , the accumulation rate was 710-980 kg maize-C ha −1 . After 14 years with continuous silage maize, maize-derived C accounted for 7-18% of the total soil C; with additional maize biomass inputs, maize-C made up 18-31%. The retention in soil of the C added in above-ground maize biomass averaged 11-15%. The >2 mm maize residues accounted for 7-21% of all the maize-C retained in soil after 11 years of maize cropping. Between 17 and 41% of the maize-C found in <2 mm soil was associated with POM. The amount and composition of the POM reflected the intensity of maize residue inputs but POM did also include biologically recalcitrant organic matter derived from pre-maize vegetations. In Danish light-textured soils with moderate C concentrations and with a history of cereal dominated cropping, continuous silage maize was able to increase soil C storage. Changes in 13 C natural abundance showed that the accumulation of maize-C was substantial even in soil showing moderate changes in soil total-C.

“…C input through maize residues during the period 1999-2015 was only 5.1 Mg ha −1 in the Control, but ranged from 7.1 to 14.1 Mg C ha −1 in the treatments amended with N, straw or both ( Table 2). Cultivation of grain maize can provide an annual C input of 5-15 Mg ha −1 (Clapp et al 2000;Liang et al 1998). However, the C input from forage maize is usually much lower, since most of aboveground biomass is harvested.…”

Fate of straw- and root-derived carbon in a Swedish agricultural soil

To maximise carbon (C) storage in soils, understanding the fate of C originating from aboveground and belowground residues and their interaction with fertiliser under field conditions is critically important. The use of 13 C natural abundance provides unique opportunities to separate both C sources. We investigated the effect of 16 years of C3 straw and C4 root input, with and without nitrogen (N) addition, on SOC stocks and C distribution in soil fractions in the long-term frame trial at Ultuna, Sweden. The straw C input was fixed at 1.77 Mg ha −1 year −1 , while the root input depended on maize plant growth, enabling studies on how N fertilisation affected (i) stabilisation of residues and (ii) plant C allocation to belowground organs. Four treatments were investigated: only maize roots (Control), maize roots with N (Control + N), maize roots and straw (Straw) and maize roots, straw and N (Straw + N). After 16 years, 5.6-8.9% of the total SOC stock in the 0-20 cm soil layer was maize-derived. In all four treatments, the relatively labile SOC fractions decreased, while the proportion of more refractory fractions increased. Based on allometric calculation of root inputs, retention of maize roots was 38, 26, 36 and 18% in the Control, Control + N, Straw and Straw + N treatments, respectively. The estimated retention coefficient of C3 straw in the Straw + N treatment was higher than that in the Straw-N treatment. We interpreted these results thus (1) roots were better stabilised in the soil than straw; (2) N fertilisation caused a shift in root to shoot ratio, with relatively more roots being present in Ndeficient soil; and (3) N fertilisation caused greater stabilisation of residues, presumably due to increased microbial C use efficiency.

Long‐term no‐tillage management and crop residue amendments to soil were identified as an effective measure to increase soil organic carbon (SOC). The SOC content, SOC stock (SOCs), soil carbon sequestration rate (CSR), and carbon pool management index (CPMI) were measured. A stable isotopic approach was used to evaluate the contributions of wheat and maize residues to SOC at a long‐term experimental site. We hypothesized that under no‐tillage conditions, straw retention quantity would affect soil carbon sequestration differently in surface and deep soil, and the contribution of C3 and C4 crops to soil carbon sequestration would be different. This study involved four maize straw returning treatments, which included no maize straw returning (NT‐0), 0.5 m (from the soil surface) maize straw returning (NT‐0.5), 1 m maize straw returning (NT‐1), and whole maize straw returning (NT‐W). The results showed that in the 0–20 cm soil layer, the SOC content, SOCs, CSR and CPMI of the NT‐W were highest after 14 years of no‐tillage management, and there were obvious differences among the four treatments. However, the SOC, SOCs, and CSR of the NT‐0.5 and NT‐W were the highest and lowest in 20–100 cm, respectively. The value of δ13C showed an obviously vertical variability that ranged from –22.01‰ (NT‐1) in the 0–20 cm layer to –18.27‰ (NT‐0.5) in the 60–80 cm layer, with enriched δ13C in the 60–80 cm (NT‐0.5 and NT‐1) and 80–100 cm (NT‐0 and NT‐W) layers. The contributions of the wheat and maize‐derived SOC of the NT‐0.5, NT‐1 and NT‐W increased by 11.4, 29.5 and 56.3% and by 10.7, 15.1 and 40.1%, relative to those in the NT‐0 treatment in the 0–20 cm soil layer, respectively. In conclusion, there was no apparent difference in total SOC sequestration between the NT‐0.5, NT‐1, and NT‐W treatments in the 0–100 cm soil layer. The contribution of wheat‐derived SOC was higher than that of maize‐derived SOC.
