Nanoparticles – a new study suggests they could stunt crop growth

A new study on nano-zinc oxide and nano-cerium oxide, two common nano particles, suggests that they can accumulate in crops such as soybeans and may stunt soil- fertilising bacteria. These findings may have food supply implications. Zinc oxide (ZnO) and … Continue reading

Lessons from Hanoi

The 2nd Global Conference on Agriculture, Food Security and Climate Change, which took place in Hanoi, Vietnam in early September, stressed the urgency of “climate-smart” agriculture. This seeks to increase agricultural productivity in an environmentally and socially sustainable way, whilst … Continue reading

Sentinel plants for pathogen detection

A Colorado State University laboratory is developing a unique plant-based method of detecting the arrival of high risk agricultural pathogens in new areas which will allow widespread, continuous and real-time monitoring. By designing receptors that influence the plant’s signalling pathway, … Continue reading

Replacing herbicides with robots

A US company has received funding to commercialise a prototype weed-pulling robot that will reduce herbicide use. The ‘lettuce-bot’ uses algorithms to detect and differentiate between plants, even if they are touching. When it detects a weed, it injects enough … Continue reading

Will pork be off the menu next year?

A global shortage of cereal crops, driven mainly by drought in the US, has lead to huge spikes in the cost of pig-feed. This in turn means that the cost of producing a pig is now much higher than the … Continue reading

New soil-free farms reduce land and water pressure

This gallery contains 1 photo.

The Waseda University in Japan has developed an alternative technology which allows farmers to grow crops without soil. Not only does this offer the potential to reduce land use pressure (by negating the need for nutrient-rich soil), it also offers … Continue reading

New agricultural methods could halve food price inflation

New research by The International Food Policy Research Institute has found that resource conservation technologies could halve increases in food prices. If drought resistant varieties for rain-fed crops are fully adopted over the next 30 years this could increase maize, … Continue reading
