To effectively contribute to climate change mitigation, agronomists are increasingly focused on minimizing the application of synthetic fertilizers and pesticides while ensuring that crop yield and quality are not compromised. Plant biomass and organic fertilizers are known to improve soil quality, boost plant growth, and suppress diseases. However, their overall effectiveness remains limited, hence the need for further research to enhance their agricultural performance. This study aims to explore the potential application of two natural sources (manure digestate and crop ) for crop fertilization and protection. During the growing season, winter wheat was fertilized twice (21-25 BBCH and 30-35 BBCH) with synthetic, organic (pig manure digestate), and combined synthetic-organic fertilizers. biomass was incorporated before sowing and planted in strips. The soil chemical composition, crop overwintering, weediness, and diseases were assessed after two years of the respective treatments. The results showed that the organic carbon content increased by 1-5% after fertilizing winter wheat with pig manure digestate and combining fertilizers (organic and synthetic). Additionally, fertilizer or pesticide use had a significant effect on the soil pH process. Combining synthetic and organic fertilizers increased the amount of mobile phosphorus in the soil by 38%. In conclusion, combining synthetic fertilizers with organic fertilizers is the most effective approach to maintain healthy soil conditions and prevent damage to sprouts in the soil. Overall, our findings offer more opportunities for organic and sustainable agricultural processes by integrating pig manure digestate and biomass as a natural approach to minimizing synthetic fertilizer and pesticide use.
为了有效地促进气候变化缓解，农学家越来越关注在确保作物产量和质量不受影响的同时，尽量减少合成肥料和农药的使用。已知植物生物质和有机肥料可以改善土壤质量、促进植物生长并抑制病害。然而，它们的整体效果仍然有限，因此需要进一步研究以提高其农业性能。本研究旨在探索两种天然来源（沼液和作物生物质）在作物施肥和保护方面的潜在应用。在生长季节，冬小麦分两次（21 - 25叶龄期和30 - 35叶龄期）施用合成肥料、有机肥料（猪粪沼液）以及合成 - 有机混合肥料。生物质在播种前施入并条播种植。在各自处理两年后，评估土壤化学成分、作物越冬情况、杂草生长情况和病害情况。结果表明，用猪粪沼液和混合肥料（有机和合成）给冬小麦施肥后，有机碳含量增加了1 - 5%。此外，肥料或农药的使用对土壤pH值变化过程有显著影响。合成肥料与有机肥料混合使土壤中有效磷含量增加了38%。总之，将合成肥料与有机肥料结合是维持土壤健康状况和防止土壤中幼苗受损的最有效方法。总体而言，我们的研究结果通过将猪粪沼液和作物生物质作为减少合成肥料和农药使用的天然方法进行整合，为有机和可持续农业生产过程提供了更多机会。
