  Organic fertilizers ll OPEN ACCESS Using organic fertilizers offers an effective strategy for preserving soil organic carbon (SOC) levels and preventing soil salinization. Derived from natural sources like animal manure, compost, or cover crops, organic fertilizers deliver numerous benefits to soil health and fertility.65 By introducing organic matter into the soil, these fertilizers contribute to SOC enrichment. This organic matter serves as a carbon source that stimulates the activity of soil microorganisms, leading to the decomposition of organic materials. Consequently, this process releases essential nutrients into the soil, supporting plant growth while increasing SOC levels. By maintaining or augmenting SOC, organic fertilizers enhance soil structure and bolster water-holding capacity,66 effectively reducing the risk of soil salinization. Furthermore, organic fertilizers are vital in enhancing nutrient cycling and availability in the soil. The organic matter in these fertilizers acts as a reservoir of nutrients, slowly releasing them over time, thus reducing the likelihood of nutrient leaching and runoff.67 This efficient nutrient management helps maintain a balanced soil ecosystem and prevent the accumulation of salts, a major cause of soil salinization. Having said that ensuring a consistent and reliable supply of organic materials can be difficult due to factors such as availability, transportation, and cost. Second, determining the optimal application rates and timing of organic fertilizers demands a thorough understanding of soil characteristics and crop requirements.
