We sampled sewage sludge from 13 wastewater treatment plants across three states. We found every resident adds microplastics to farmland, in dried sewage sludge (biosolids) used as fertiliser.
The health of our soils is poor – and getting worse. Here’s why that matters and what we can do about it
Sydney’s 14 wastewater treatment plants could be modified to also accept food waste, research shows. The ‘anaerobic digestion’ process would produce energy as well as nutrients for reuse.
Insect-eating birds such as swifts and yellow wagtails are particularly vulnerable.
A third of South Africa’s farming income depends on irrigation. Disruptions in power supply put huge chunks of the country’s agricultural fortunes at risk.
Many of our rivers are overloaded with nutrients from fertiliser run off and wastewater. Algal blooms, fish kills and poor water follow. One solution? Nutrient offsetting.
New research finds that some common houseplants take in nutrients from outside the soil.
A slowdown in price rises, combined with the shift to less aggressive rate hikes, is good news for the minister’s budget initiatives on growth.
Pulses are important for many reasons. They are packed with nutrition, resilient and crucial for achieving food security in Africa.
Several batches of palm kernel product imported for dairy farms contained certain chemicals above a safe limit – and there’s an ethical quandary in supporting an industry linked with deforestation.
For now there is little hope of a peace deal, but back-channel agreements show that Ukraine and Russia are at least talking.
This crucial fertiliser component is mostly found in just five countries.
The ravages of climate change and hunger do not occur in isolation, but are part of the system we have built.
A key ingredient for a green future is currently derived from fossil fuels.
Algorithms can help determine what farm inputs and policies can boost food production.
How well Morocco manages challenges to its fertiliser industry will affect its own development and the stability of food supplies across the world.
The impacts of Russia’s invasion of Ukraine will pass, but the impacts of climate change will not.
Up to 42,000 tonnes a year of microplastics are removed from sewage, spread on fields as fertiliser and eventually wash back into watercourses.
Wheat and bread play a central role for food security and political stability in Sudan.
