CH 4 release rates from rice paddies were measured in Vercelli, Italy, in during a complete vegetation period, using a static box system. The rice paddies were found to be a source of atmospheric methane during the time of flooding. Significant differences in the CH 4 release rates of unfertilized field plots and plots fertilized with mineral fertilizer CaCN 2 were not observed. The CH 4 release rates show strong diurnal variations, with highest values in the late afternoon and lowest values in the early morning, which coincides with the temperature variation in the upper soil layer 1—10 cm.

Outliers: The Story of Success - Part 2, Chapter 8, Rice Paddies and Math Tests Summary & Analysis

Chapter 8 is called "Rice Paddies and Math Tests. Rice paddies, Gladwell explains, are complicated systems that require careful planning and regular attention. They must be perfectly level, the plants must be properly spaced and the paddies must be irrigated properly. They are usually weeded and harvested by hand and two crops can be planted and harvested each year. Unlike the cultivation of crops like wheat, which require very little attention during the growing season, rice requires the farmer to be working on his paddies continually throughout the year.

The rice is grown in paddies which are small but require close monitoring and coordination. The people that cultivate rice need know how it's fertilized, how to maintain certain water levels, how to choose which type of rice to plant. Gladwell emphasizes rice has been fundamental to the chinese diet and economy for centuries.

Jump to navigation. Rice is the staple food of 3 billion people, providing one-fifth of calories consumed worldwide. Its cultivation is responsible for at least 10 percent of agricultural greenhouse gas emissions and 9 to 19 percent of global methane emissions. That is because flooded rice paddies are ideal anaerobic environments for methane-producing microbes that feed on decomposing organic matter, a process known as methanogenesis. There are four general techniques, best used in combination, to improve rice production and reduce emissions:. These techniques can make rice production efficient, dependable, and sustainable, helping to meet growing demand for this staple food without causing warming.
