ABSTRACT
In Chapter 2, the authors focus on the importance of precision-based soil and nutrient management practices tested on rice farms in the eastern part of India and the potential for reducing GHG emissions. This is highly relevant for countries such as India, Vietnam, Myanmar, Bangladesh, and Thailand with large areas under rice production, where the use of excess amounts of fertilizer and chemicals, especially nitrogen fertilizer, is a serious problem for the environment and health of people. The chapter shows the importance and benefits from the use of tools ranging from the simple leaf colour chart to innovative digital tools and their relevance to improve nutrient use efficiency. The chapter towards the end provides guidelines/models and policy recommendations for upscaling precision soil and nutrient management in rice systems and other related food crops.
