Outside Asia, no country produces as much rice as does Brazil. It is the ninth largest rice producer in the world. Average annual yields are close to 15 million tons.Rice production in Brazil is a multi-billion dollar industry. It employs hundreds of thousands of people, directly and indirectly.Given the importance of rice farming in Brazil, […]
In a newly published study, researchers dug into how fertilizing with manure affects soil quality, compared with inorganic fertilizer. Ekrem Ozlu of the University of Wisconsin-Madison and his team studied two fields in South Dakota. From 2003 to 2015, the research team applied either manure or inorganic fertilizer to field plots growing corn and soybeans. […]
India's first fully organic state, Sikkim, won top prize in a UN-backed award on Friday, with organisers saying its policies had helped more than 66,000 farmers, boosted tourism and set an example to other countries. Sikkim was declared fully organic in 2016 after phasing out chemical fertilisers and pesticides and substituting them with sustainable alternatives. […]
Scientists expect climate change influences the geographical distribution of microbes in the soil, but few studies have dug deeply into that relationship. A study published this week in mSystems suggests the connection can drag across decades. After sequencing soil samples from North American and the Tibetan plateau, and comparing those to historical climate records, an […]
The findings come from an analysis of the rates of change of carbon in soil by scientists at Rothamsted Research where samples have been collected from fields since 1843. They are published today in Global Change Biology. The idea of using crops to collect more atmospheric carbon and locking it into soil's organic matter to […]
Globally, forest trees are increasingly at risk from habitat destruction, pests and disease, and a changing climate. But the guidelines for effective preservation of a tree species’ genetic diversity and adaptive potential have been limited to simple mathematical equations for crop collections from the 1970s, or best guesses based on intuitions. Globally, forest trees are […]
An international research team found that planet warming drove major changes in vegetation and future warming may drive similarly dramatic changes around the world. As the last ice age came to an end and the planet warmed, the Earth’s vegetation changed dramatically, reports a University of Arizona-led international research team in the journal Science. The […]
Widespread use of proven agricultural land management practices can help slow global warming. Low-tech ways of improving soil quality on farms and rangelands worldwide could pull significant amounts of carbon out of the atmosphere and slow the pace of climate change, according to a new UC Berkeley study. The researchers found that well-established agricultural management […]
In a new study published in the Proceedings of the National Academy of Sciences, researchers reveal techniques – inspired by the study of information theory – to track how changes in precipitation alter interactions between the atmosphere, vegetation and soil at two National Science Foundation Critical Zone Observatory sites in the western United States. “Information […]
A new research study published in the journal Invasive Plant Science and Management tackles those questions and provides insights that can benefit land managers. Researchers from Miami University investigated the relative importance of seed dispersal, canopy disturbance, and soil disturbance on four invasive species growing in a mature Maryland forest: wine raspberry, Japanese barberry, multiflora […]
