Yamaha Remotely Piloted Helicopters
Yamaha unmanned helicopters are designed for a wide range of industrial and research applications and have been operating commercially since 1991. Originally engineered for agricultural spray applications on rice paddies in Japan, Yamaha units are now also being used in Australia, Korea, New Zealand, Thailand and the United States. Yamaha has established a Spray Services office in Napa, CA to ...

Management of rice paddy fields affects greenhouse gas emissions
How rice paddy fields are managed significantly influences the release of greenhouse gases (GHGs), a recent study concludes. Permanently flooded soils release more methane than soils that are flooded and then dried between production periods, for example. In general, the researchers recommend growing other crops in dried soil between production cycles, as well as limiting nitrogen fertilisers, to ...

Nepal`s shifting rains and changing crops
With weather becoming more erratic every year as a result of climate change, Nepali farmers are progressively shifting their approach, turning vast areas of rice paddies into small-scale vegetable farming. Vegetables are more resilient as they can be hand watered in case of drought. Farmers say that with rains that used to come in April now shifting as late as mid-June, vegetables that can be ...

Rice paddies raise methane threat
Directly seeding rice into fields rather than transplanting it into flooded paddies would dramatically reduce methane emissions and slow down climate change, according to scientists studying the staple crop. A number of experiments in Asia, particularly in the Philippines and Japan, show that a change in the way rice is grown would have considerable other benefits in saving water and improving ...

Rice paddies synergise with fish farming
By combining aquaculture with wet paddy farming in its coastal areas Bangladesh can meet food security and climate change issues, says a new report. The approach promises more nutritious food, without causing environmental damage, and has the potential for a 'blue-green revolution' on Bangladesh’s existing crop areas extending to about 10.14 million hectares and an additional 2.83 million ...

Fighting selenium deficiency
Approximately 1 billion people worldwide suffer from a deficiency of selenium, an essential nutrient for liver, heart, thyroid, and immune function. Since selenium deficiency is prevalent in Southeast Asia, researchers are studying the best biofortification for lowland rice production. In a study funded by the Commonwealth Government of Australia, the soil retention of three types of selenium was ...

Crops and soil threatened by floods in the Midwest
Here, in some of the best soil in the world, the stunted stalks of Dave Timmerman's newly planted corn are wilting in what sometimes look more like rice paddies than the plains, the sunshine glinting off of pools of collected water. Although time is running out, he has yet to plant all of his soybean crop because the waterlogged soil cannot support his footsteps, much less heavy machinery. Mr. ...

Compost and climate change: a novel mitigation strategy?
Native soils are thought to take up more of the greenhouse gas methane than land used for farming. This study shows that, while agriculture can exert an adverse impact on soil methane uptake, the application of soil conditioners like compost may compensate for loss of the methane sink function. The researchers propose new land management strategies based on this finding. Agriculture has become ...

Vietnam eyes water-saving technology for its rice farms
Agriculture experts say application of alternate wetting and drying (AWD) technology in Vietnam’s rice farms, one of South-East Asia’s largest rice-producing countries, holds great promise in cutting water use and greenhouse gas emissions from rice cultivation without sacrificing yield output. Vietnam along with Bangladesh and Colombia recently partnered with the Climate and Clean ...

Rising temperatures take their toll on rice pest
A warming climate and occasional extreme high temperature events in tropical countries are likely to limit both the survival and distribution of the brown planthopper, a pest that has devastated rice crops in India, Indonesia, Thailand and Vietnam, according to UK researchers. The scientists, based at the University of Birmingham, measured the upper thermal thresholds that could be survived by ...

Typhoon-stricken farmers receive first emergency seeds
One month after Typhoon Haiyan struck a devastating blow to the Philippines, farmers who lost essential crops and supplies are receiving the first wave of emergency seeds, restoring hope for a productive planting season and much-needed food for the coming year. FAO and the Philippines' Department of Agriculture (DA) have begun delivering the first rice and corn seed allocations to rural ...

Cows’ diets get environmental boost
It is a tiny molecule with a mouthful of a name, 3-nitrooxypropanol, but European scientists say it could make all the difference. It could convert a cow or a sheep from a monstrous methane-producing machine into something a little more environmentally friendly. In doing so, it could increase the energy that a ruminant could employ in making milk or meat. And, according to a new research ...

Floods wash away Pakistan`s crop research efforts
The recent Pakistan floods have caused substantial damage to the country's crop research, washing away new seed varieties and test crops planted in the fields, and damaging buildings and equipment, leaving the country's research institutes in disrepair. So far, the floods have killed more than 2,000 people and affected a further 21 million, killed 200,000 livestock and destroyed 4.25 million ...

Feed Pellet Extruder Machine For Fish Feed Making
Fish feed is a vital factor to be concerned in fish farming. Fish feed extruder machine for making feed pellets. High quality fish feed can improve fish living environment and ensure healthy growth of fish stock. Therefore, before farmers opt the diet for fish, they should first know the basic nutritional needs of fish. Carbohydrates, protein, fat, vitamin, and minerals are the essential ...

Scientists take on greenhouse gas challenge
Swiss scientists have found a way to turn the potent greenhouse gas methane into the fuel methanol – with help from water and a simple catalyst. Meanwhile, US researchers have tested a way to convert methane into biofuels, specialised chemicals or even cattle feed with help from one microbe from rice fields and another from a Siberian lake. And in Norway, engineers are testing something ...

Bats can help protect rice farms against pests
Bats that prey on a major rice pest in Thailand could save paddy harvests worth millions of dollars and help contribute to better food security, scientists say in a paper published in Biological Conservation in March. Using data from a previous study and their own field survey, the scientists came up with a value of the predation of the wrinkle-lipped bat (Tadarida plicata) on the white-backed ...
