Transplanters are specialized tools or machines used in agriculture to move young plants or seedlings from one location to another. They help ensure that plants are placed in the soil at the right depth and spacing, which is crucial for their growth and development. This process can be done manually or with the help of mechanical transplanters, which can increase efficiency and reduce labor costs. These devices are commonly used in the cultivation of crops like rice, vegetables, and flowers. By automating the transplanting process, farmers can save time and improve the overall health of their plants, leading to better yields and more productive farming practices.
