Abstract
Urea Deep Placement (UDP) is an advanced fertilization method designed to optimize nitrogen use in irrigated rice farming. This technology involves placing urea briquettes, also known as urea supergranules (USG), at a depth of 7-10 cm in flooded paddy fields, approximately 7-10 days after transplanting rice seedlings. The urea briquettes, which are placed between every four plants, dissolve gradually, providing a steady supply of nitrogen throughout the rice crop's growth cycle. UDP offers several benefits, including a reduction in nitrogen fertilizer use by 30%, increases in paddy yields by 15-30%, improved grain quality, and a decrease in weed infestation. Additionally, it helps lower production costs, providing farmers with increased gross profit margins. However, the technology does present some constraints, such as the need for heavy soils, good land leveling, a consistent water supply, and the manual labor required for briquette placement. Despite the additional cost of urea briquettes, UDP technology contributes to more efficient fertilization practices, promoting sustainability and higher crop productivity.
