[Audio] Aerobic rice is an innovative practice in rice cultivation which has the potential to create greater efficiency and sustainability. Rather than flooding fields with water, this type of rice cultivation does away with the need for puddling and is planted in non-saturated soil. Such a method has the potential to save resources, such as water, and also to reduce emissions of greenhouse gases, potentially leading to increased yields..

[Audio] A land evaluation framework for promoting aerobic rice cultivation in the dry and intermediate zones of Sri Lanka has been devised. This framework not only provides farmers, agricultural professionals, and stakeholders with the knowledge and tools to make informed decisions regarding land suitability but it also offers a comprehensive understanding of the process and its significance in determining the suitability of an area for aerobic rice cultivation. This knowledge can help farmers make more informed decisions on what types of rice to grow, leading to increased yield and profits..

[Audio] Rice is an essential crop in Sri Lanka, offering aliment and sustenance to a lot of people. Particularly important for the production of aerobic rice is the Dry and Intermediate Zones, which have different types of soil, fertility, topography and water resources. To benefit from this variety of land characteristics a land evaluation framework was developed in order to design the best land-use to optimize the potential of the land for aerobic rice production. By implementing this framework, farmers are able to better manage their land, thus obtaining higher yields and better living conditions..

[Audio] Rice Fields Paddy Cultivation is an issue of great significance. This discussion will focus on the land assessment system for aerobic rice farming in Sri Lanka's dry and intermediate zones, which have experienced a sharp rise in agricultural problems lately due to lack of water sources and unpredictable climatic conditions, leading to a difficult financial situation for farmers in need of a dependable and sustainable solution. Aerobic rice farming could be a good substitute for usual paddy cultivation in dry and intermediate zones where rainfall is reduced and irrigation is not available. Everyone should collaborate to bring the advantages of aerobic rice farming to Sri Lanka's dry and intermediate zones, thereby ensuring a better life for the farmers living there..

[Audio] Today, I want to discuss the land evaluation framework, which can help farmers in Sri Lanka's dry and intermediate zones increase their yields and economic prospects. To do this, we need to evaluate factors such as soil quality and water availability, and use this information to identify the most suitable areas for aerobic rice farming. We also need to help farmers make informed decisions about their crops. By doing this, we can ensure the effective implementation of this new, water-efficient rice farming approach..

[Audio] Aerobic rice is a modern and improved way to cultivate rice that is kinder to the environment and yet just as productive. It is a farming method that does not involve puddling the soil and keeping it continuously saturated with water. Different irrigation techniques are used such as furrow irrigation, drip irrigation, or intermittent flooding to provide the plants with water only when necessary. This helps conserve water resources more effectively. This method also results in improved soil aeration, which helps the plants to get the nutrients they need and leads to better root development. All of this adds up to a farming technique that is more sustainable to the environment and just as productive as traditional paddy farming methods..

[Audio] Aerobic rice cultivation provides advantages for both farmers and the environment. Controlled irrigation and optimized water usage contribute to better water conservation in comparison to non-aerobic rice cultivation. In addition, better water management and aeration lead to increased productivity, resulting in higher grain yields with more efficient use of resources such as water and fertilizers. Furthermore, aerobic rice cultivation also lowers greenhouse gas emissions, like methane, therefore it is a more sustainable agricultural method..
