Grow green onions at low cost with ditch manure fertilization technology

This video explains the practical technology of growing green onions at low cost by adopting ditch manure fertilization. Green onions have shallow root systems and fast growth rates with a high nutrient demand during the growing period. Traditional extensive fertilization methods such as flood irrigation and broadcast spreading easily cause nutrient volatilization and loss as well as uneven fertilization. They may also burn the stems and leaves of green onions and greatly reduce the nutrient absorption efficiency of the roots. Ditch manure fertilization perfectly matches the growth habits of green onions and serves as an efficient and practical preferred method for field fertilization. During operation, farmers carry buckets filled with decomposed manure water and walk steadily along the green onion ridges. The manure water is evenly poured into the furrows between two rows of green onions to fully cover the bottom of the furrows and moisten the soil around the root growth area. Compared with traditional full-area flood irrigation, ditch manure fertilization enables precise and targeted fertilization, keeping nutrients retained in the soil layer where green onion roots are densely distributed. It allows the roots to quickly and directly absorb organic nutrients to continuously supply growth for stems and leaves. Meanwhile, it effectively avoids fertilizer exposure and volatilization as well as nutrient loss, and prevents stem and leaf burns caused by direct contact with fertilizer. This technology is simple to operate with no additional cost investment, making it highly suitable for small-scale scattered planting by farmers. It can also improve the rhizosphere soil of green onions, promote robust root development, and help achieve stable yield and better quality of green onions.
