The ultimate crop yields that farmers harvest depends on the use of fertilisers.
Many of our planet’s ecosystems depend on the health of soil.
If we want to reduce carbon emissions and preserve planetary ecosystems, we need to protect our soils.
Ghana’s Green Revolution has not been as successful as portrayed.
Realities on the ground tell a different story from the claim that a Green Revolution ensures food security and increased income for smallholder farmers in Ghana.

Guano helped humans farm the world’s driest desert, new research finds.
If rolled out worldwide, our method could replace a quarter of all the synthetic nitrogen fertiliser used in agriculture.
Ammonium nitrate in granular form is the basis for many nitrogen fertilisers.
What do ammonium nitrate and iodine have in common? Both substances are of immense service to humankind, and the history of their discovery is closely linked to that of the production of explosives.
Agriculture is the dominant cause for the increasing N₂O concentrations. Emissions must be reduced if we hope to stabilise Earth’s climate.
It’s painfully clear nature is buckling under the weight of farming’s demands. There’s another way – but it involves accepting nature’s limits.

And why development funders should listen to smallholder farmers
Phosphorus was first discovered by boiling down thousands of litres of urine.
We need phosphorus for life, as well as for fertiliser to help plants grow, but raw supplies are limited.
Wildflowers, bees and butterflies – your lawn is a vibrant ecosystem waiting to be unleashed.
Feeding pigs seaweed could make them, us and the planet healthier without contributing to antibiotic resistance in bacteria.
Every flush by a typical toilet sends about 6 to 16 litres of fresh water to wastewater treatment centres.
Existing toilets aren’t a good fit for parts of sub-Saharan Africa because many areas lack water and there’s often no proper plumbing.
Crops, soils and fungus are a tricky mix.
An ancient relationship between plants and fungi could be used in sustainable agriculture. But there’s still a lot we don’t know, and new research suggests these fungi can sometimes do more harm than good.
Ammonia production is one of the most energy-intensive industrial processes on the planet.
Producing ammonia, which is a key ingredient in fertilizers, is one of the world’s most energy-intensive chemical manufacturing processes. Now there’s a new low energy option in development.
The new funding is focused on measures that are already in the foreground.
The federal government’s new $500 million funding package for the Great Barrier Reef seems predominantly focused on the tactics that are already being tried, without much success.
Coffee’s usefulness doesn’t have to end here.
Plenty of cafes these days will let you take home some used coffee grounds, to put on your garden. It’s a versatile material with loads of potential uses - as long as you treat it properly first.

There were some African food security initiatives from 2017 that deserve a special mention for the precedent they set.
Water quality is one of the major issues that threatens the Great Barrier Reef’s health.

The updated plan for improving water quality on the Great Barrier Reef still doesn’t address the need to curb intensively farmed crops such as sugar cane, and to enforce existing environmental laws.
