The biochemical composition of organic fertilizers largely determines their nutrient supply characteristics following soil application as well as their potential impact on soil microbial communities. Yet, limited information is available regarding the biochemical composition of organic fertilizers derived from different nutrient sources. Here, we qualitatively analyzed the presence and abundance of proteins, lipids, and metabolites in a liquid fish fertilizer (LFF) product and a type of granular organic fertilizer (GOF) commonly used in organic vegetable production, using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Our results suggest that the presence and abundance of proteins, lipids, and metabolites differ greatly between GOF and LFF. The qualitative analysis shows LFF as a rich source of metabolites, while complex proteins and long-chain saturated fatty acids are dominant in GOF. The degree of biochemical composition complexity may help explain the varying impacts of different types of organic fertilizers on nutrient availability, soil health, and environmental quality.

有机肥料的生化组成在很大程度上决定了其施用于土壤后的养分供应特性以及对土壤微生物群落的潜在影响。然而，关于源自不同养分来源的有机肥料的生化组成的信息有限。在此，我们使用液相色谱 - 串联质谱法（LC-MS/MS）对一种液体鱼肥（LFF）产品和一种有机蔬菜生产中常用的颗粒有机肥（GOF）中的蛋白质、脂质和代谢物的存在及丰度进行了定性分析。我们的结果表明，GOF和LFF之间蛋白质、脂质和代谢物的存在及丰度差异很大。定性分析表明，LFF是代谢物的丰富来源，而复杂蛋白质和长链饱和脂肪酸在GOF中占主导地位。生化组成的复杂程度可能有助于解释不同类型有机肥料对养分有效性、土壤健康和环境质量的不同影响。
