“…S1). In our study, 26.0% straw N recovery was shown in maize at the maturity, moreover, a substantial amount of recalcitrant N in the straw [37,38] under this equivalent N amendment experiment was mainly responsible for the significantly (P < 0.05) lower 39.5 -47.8% exogenous substrate N uptake in the shoots from the R1 stage, 11.6 -29.1% of exogenous substrate N uptake in the roots from the V8 stage in the urea plus straw treatment compared with the urea-only treatment (Fig. 1a & b), and the lower straw N recovery in different maize parts in the 15 NS + U treatment than the other two treatments ( Table 2).…”

A 15N maize pot experiment was conducted to compare the N value of fertilizer alone and fertilizer combined with straw at an equivalent N rate. The four treatments were control (CK), 15N-urea, 15N-urea plus straw, and 15N-straw plus urea. Soil N pools, maize N and their 15N abundance were determined during maize growth. At maturity 26.0% of straw N was assimilated by maize in the urea plus straw treatment. From the eighth leaf stage to maturity, urea plus straw had a significantly (P < 0.05) higher concentration and percentage of exogenous substrate N present as soil total N (TN), particulate organic N (PON), and mineral associated total N (MTN) in bulk and rhizosphere soils than the urea-only treatment. From silking to maturity in the urea plus straw treatment, rhizosphere soil significantly (P < 0.05) increased the percentage of exogenous substrate N present as inorganic N (Inorg-N) and MTN, and significantly (P < 0.05) decreased that present as PON and microbial biomass N (MBN) compared with the bulk soil. From the eighth leaf stage to maturity, rhizosphere soil significantly (P < 0.05) increased the percentage of straw N present as Inorg-N and MTN except for MTN at the silking stage, and significantly decreased (P < 0.05) that present as PON compared with the bulk soil. Overall, straw was an available N source to the crop, and the increase in straw N availability needs to be considered from the interaction of fertilization practices and the crop rhizosphere.

“…In our study, the effect was similar in both tillage systems because the climatic condition in our subtropical environment might have minimized the effect of partial or full incorporation into the soils. However, continuation of residue management in rice-based systems enhances C sequestration after 4 or 6 years [15], and after 12 years [52]. In our study, the ISFM with LC and BS were like the RD for SOC content.…”

“…Agegnehu et al [51] found that the trend of plant N uptake increases in relation to organic amendments and N levels are similar to the increments in the plant growth, yield, and soil nutrient status. After conducting a 7-year experiment, Takahashi et al [52] suggested that continuous application of rice straw contributes to the improvement of soil fertility and the promotion of growth and N uptake of paddy and upland crops. Conversely, Phongpan and Mosier [53], in a 1-year experiment in Thailand, observed no difference in N uptake between rice residue retention and no residue retention, which is in opposition to our results.…”

Bio-Compost-Based Integrated Soil Fertility Management Improves Post-Harvest Soil Structural and Elemental Quality in a Two-Year Conservation Agriculture Practice

The impacts of integrated soil fertility management (ISFM) in conservation agriculture need short-term evaluation before continuation of its long-term practice. A split-split plot experiment with tillage (minimum tillage, MT vs. conventional tillage, CT) as the main plot, residue (20% residue, R vs. no residue as a control, NR) as the sub-plot, and compost (Trichocompost, LC; bio-slurry, BS; and recommended fertilization, RD) as the sub-sub plot treatment was conducted for two consecutive years. Composite soils were collected after harvesting the sixth crop of an annual mustard-rice-rice rotation to analyze for nutrient distribution and soil structural stability. The LC increased rice equivalent yield by 2% over RD and 4% over BS, and nitrogen (N) uptake by 11% over RD and 10% over BS. Likewise, LC had higher soil organic carbon (SOC), N, and available sulphur (S) than BS and RD. Conversion of CT to MT reduced rice equivalent yield by 11%, N uptake by 26%, and N-use efficiency by 28%. Conversely, soil structural stability and elemental quality was greater in MT than in CT, indicating the potential of MT to sequester C, N, P, and S in soil aggregates. Residue management increased rice yield in the second year by 4% and corresponding N uptake by 8%. While MT reduced the yield, our results suggest that ISFM with Trichocompost and residue retention under MT improves soil fertility and physical stability to sustain crop productivity.

Reducing ammonia (NH 3) volatilization is a practical way to increase nitrogen (N) fertilizer use efficiency (NUE). In this field study, soil was amended once with either cotton (Gossypium hirsutum L.) straw (6 t ha −1) or its biochar (3.7 t ha −1) unfertilized (0 kg N ha −1) or fertilized (450 kg N ha −1), and then soil inorganic N concentration and distribution, NH 3 volatilization, cotton yield and NUE were measured during the next two growing seasons. In unfertilized plots, NH 3 volatilization losses in the strawamended and biochar-amended treatments were 38-40% and 42-46%, respectively, less than that in control (i.e., unamended soil) during the two growing seasons. In the fertilized plots, NH 3 volatilization losses in the straw-amended and biochar-amended treatments were 30-39% and 43-54%, respectively, less than that in the control. Straw amendment increased inorganic N concentrations, cotton yield, cotton N uptake and NUE during the first cropping season after application, but not during the second. In contrast, biochar increased cotton N uptake and NUE during both the first and the second cropping seasons after application. Furthermore, the effects of biochar on cotton N uptake and NUE were greater in the second year than in the first year. These results indicate that cotton straw and cotton straw biochar can both reduce NH 3 volatilization and also increase cotton yield, N uptake and NUE. In addition, the positive effects of one application of cotton straw biochar were more long-lasting than those of cotton straw.
