How will the farms of the future feed a projected 9.8 billion people by 2050? Berkeley Lab's 'smart farm' project marries microbiology and machine learning in an effort to reduce the need for chemical fertilizers and enhance soil carbon uptake, thus improving the long-term viability of the land while increasing crop yields.
In research published in Scientific Reports, scientists from the University of Plymouth have shown that creatures which develop in hypoxic (low oxygen) conditions in the marine environment could experience previously unseen hindered development, and become compromised as adults.
A new lightweight, low-cost agricultural robot could transform data collection and field scouting for agronomists, seed companies and farmers. The TerraSentia crop phenotyping robot, developed by a team of scientists at the University of Illinois, will be featured at the 2018 Energy Innovation Summit Technology Showcase in National Harbor, Maryland. The robot measures the traits of individual plants using a variety of sensors, including cameras, transmitting the data in real time to the operator's phone or laptop computer.
The Rassafa cotton cultivar is a relatively new variety grown in the dry areas of the Eastern Mediterranean region. Farmers have targeted the higher seed cotton yield and they assume the greater yields would need augmented N fertilizer and water quantity. So, water and nitrogen fertilizer requirements of this new cultivar need to be quantified and optimized.
Kansas State University researchers have discovered the mechanism by which pigweed develops resistance to glyphosate, a popular herbicide.
UMD researchers have pulled together forty years of data to quantify the effects of Bt field corn, a highly marketed and successful genetically engineered technology, in a novel and large-scale collaborative study. By tracking European corn borer populations, this study shows significant decreases in adult moth activity, recommended spraying regimens, and overall crop damage in vegetable crops such as sweet corn, peppers, and green beans.
An effort to improve crop yields and reduce fertilizer use applied top-down and bottom-up approaches to reach 20 million smallholder farmers across China.
With the rise of herbicide-resistant weeds in most grain and vegetable crops, farmers are looking for alternatives to herbicides to control weeds. Cover crops offer one potential weed management tool. Their use in specialty crops is limited, and no testing has been done so far in edamame. However, a new University of Illinois study reports that early-killed cereal rye shows promise for edamame growers.
This is the first comprehensive review of gaps in risk assessments for adjuvants in pesticide formulations which are not currently subject to safety assessments. Ignoring the potential dangers of other ingredients in commonly used commercial pesticides leads to inaccuracies in the safety profile of the pesticide solution, as well as confusion in scientific literature on pesticide effects. The review suggests that new regulations are needed to protect people and the environment from toxic pesticide ingredients.
Researchers from the CAS institute of Atmospheric Physics implemented a passive ammonia monitoring network based on the diffusive technique with monthly integrated measurements at 53 sites since September 2015 and presented the spatial distributions and seasonal variations in atmospheric NH3 on a national scale in China.
