So, to see how well hydrogel 2.0 works in soils, the researchers ran a sequence of experiments, which for starters measured the pace of water and fertilizer release.

Many fertilizer bags are labeled as fast- or slow-release, indicating how quickly the nutrients are available to the plant. Fast-release types dissolve in water and are readily available.

UF/IFAS researchers are testing how effective these products are by putting them in mesh bags and burying them alongside corn ...

Scientists are now working on a possible solution to that problem, by developing a sustained-release fertilizer that takes the form of tiny glass beads. SUBSCRIBE LOG IN ...

AMES, Iowa – Iowa State University researchers weren’t looking for a slow-release fertilizer that could feed crops while protecting water quality, but they may have found one. Researchers looking to ...
