“…Wu et al [69] highlighted the conversion of organic waste into fertilizer via black soldier fly larvae (BSFL), noting its positive impact on photosynthetic parameters and the overall biomass of corn plants and roots. Furthermore, multiple authors [39][40][41] advocated composting or vermicomposting organic waste, utilizing earthworms like Eisenia fetida, as a beneficial approach to managing organic waste.…”

“…Additionally, other scholars [35][36][37][38] underscore the importance of considering N 2 O and CH 4 emissions when using organic fertilizers. Yao et al [39] substantiated that leaving corn stalks in the field increased N 2 O emissions. Conversely, He et al [40], in their evaluation of various fertilization methods, found that an organic fertilizer resulted in the highest N 2 O emissions when compared to chemical fertilization, chemical/organic combinations, and control groups without fertilization.…”

The cultivation of corn holds immense importance as a foundational global grain crop, catering to human sustenance and serving as vital animal feed. Moreover, corn plays a substantial role in biofuel production. Additionally, cultivating corn can have a positive effect on crop rotation by improving soil quality and reducing erosion. In a pot trial using six distinct compost variations derived from different organic wastes as fertilizers for GS210 corn, specific indices, such as Fv/Fm (0.80, 0.80, 0.81), Fv/F0 (4.07, 3.99, 4.03), PI (4.62, 4.22, 5.21), and RC/ABS (1.71, 1.68, 2.01), exhibited the highest values. Interestingly, mineral fertilization with NPK displayed significant benefits on various growth parameters like plant height (188.9 cm), cob length (17.50 cm), grains per cob (324.0), and thousand-grain weight (MTZ) (285.2). The difference in the cob grain count between NPK mineral fertilization and the control reached 168.5 grains, which was statistically confirmed. Furthermore, the grain’s protein content notably increased with mineral fertilization (9.5) compared to the control (8.5). While organic fertilizers showed lower outcomes (9.1–9.3) than NPK mineral fertilization, they generally outperformed the control (8.5). This prompts the need for future studies to assess the effectiveness of individual organic fertilizers in combination with mineral nitrogen fertilization.

“…The N 2 O data suggest that higher portions of easily accessible organic C in smaller WC sizes promoted N assimilation or immobilization and contributed to the reduced emissions. There is no consensus regarding the effect of crop residues on N 2 O emissions as some reported increases (Yao et al, 2023) and others decreases (Zhang et al, 2023;Zhou et al, 2017). A meta-analysis showed that crop residue incorporation generally increased soil N 2 O emissions compared to residue removal and the effects on N 2 O emissions could be predicted by easily degradable fraction, structural fractions, and N returned with crop residues (Abalos et al, 2022), and crop residue maturity (Lashermes et al, 2022).…”

Incorporating large amounts of woody biomass into soil, such as in whole orchard recycling (WOR), can promote carbon sequestration, nutrient recycling, and ecosystem health in agricultural fields. Yet uncertainty regarding the effects of WOR on soil carbon (C) and nitrogen (N) dynamics influences management decisions. The objective of this research was to evaluate the effects of woodchip (WC) size and interaction with N fertilization on carbon dioxide (CO2) and nitrous oxide (N2O) emissions. An 8‐month incubation experiment incorporating WC (4% w/w, equivalent to ∼40 tons per acre) in four sieved sizes (0.2–1.6, 1.6–3.2, 3.2–6.4, and 6.4–12.7 mm) with and without N applications was conducted. All treatments with WC showed that CO2 emission peaked within the first week, then decreased drastically afterward. The CO2 peak delayed as the peak value decreased (WC size increased). The finest WC (<1.6 mm) yielded the lowest total CO2 emissions and resulted in the greatest increase in soil C at the end of incubation. Nitrogen application reduced total CO2 emissions by 1% in the smallest WC size and by 8%–9% for those larger than 1.6 mm. The N2O emissions spiked following each fertilizer application with lowest total emissions from the smallest WC size, suggesting substantial N immobilization. The results imply that larger WC sizes can delay C mineralization and reduce initial N immobilization risks, but the smallest WC size may have stabilized and increased soil organic carbon. This research increased our understanding on WC mineralization that can be used in WOR management.
