Rice is a staple food for Malaysians. With global demand for rice increasing, Malaysia needs to become more self-sufficient in rice production. However, with fertile land in short supply, farmers may need to increase their rice production on land that was previously idle and less fertile, such as the acid sulphate soils that occur along Malaysia's coastal plains.
Marked with high acidity (soil pH< 3.5), acid sulphate soils contain high levels of aluminium (Al). Under normal circumstances, they are not suitable for crop production. Major agronomic problems common to these soils include Al toxicity, decreased availability of phosphorus, nutrient deficiencies and iron toxicity.
In the study, Shamshuddin Jusop and colleagues at the Universiti Putra Malaysia treated an acid sulphate paddy with ground magnesium limestone (GML), hydrated lime and liquid lime. Prior to the treatments, the pH of water from the rice field was 3.7 and the Al concentration was 878 uM. Rice plants grown under these conditions would normally suffer from acid and aluminium stress, thus retarding and/or minimizing rice growth and yield.
For their experiment, the researchers tested paddy variety MR 219 - the most common variety grown in Malaysia. In the first season, rice plants were affected by drought while in the second, they were infested with rice blast fungus. Despite this, the rice yield was 3.5 tons (t) per hectare, or almost as much as the average national yield of 3.8 t per hectare. This was achieved by applying 4 tons of GML per hectare, at a cost of US$382. Since one ton of rice sold at the market price of US$318, "the yield obtained is worth the effort and cost," the authors conclude.

Code Halos - aka "digital fingerprints" - are the key organizing principle to understand a) how dumb things become smart and b) how to monetize this dynamic. In his session at @ThingsExpo, Robert Brown, AVP, Center for the Future of Work at Cognizant Technology Solutions, outlined research, analysis and recommendations from his recently published book on this phenomena on the way leading edge organizations like GE and Disney are unlocking the Internet of Things opportunity and what steps your o...

Scott Jenson leads a project called The Physical Web within the Chrome team at Google. Project members are working to take the scalability and openness of the web and use it to talk to the exponentially exploding range of smart devices. Nearly every company today working on the IoT comes up with the same basic solution: use my server and you'll be fine. But if we really believe there will be trillions of these devices, that just can't scale. We need a system that is open a scalable and by using ...

How do APIs and IoT relate? The answer is not as simple as merely adding an API on top of a dumb device, but rather about understanding the architectural patterns for implementing an IoT fabric. There are typically two or three trends: Exposing the device to a management framework Exposing that management framework to a business centric logic Exposing that business layer and data to end users. This last trend is the IoT stack, which involves a new shift in the separation of what stuff happe...
