Unlocking the Power of Slow-Release Fertilizers in Modern Farming

Farming is a big deal in any country's economy. To grow plants well and get more crops, farmers need to water their fields and give the soil the right nutrients. With more people in the world, we need more food. So, farmers use synthetic fertilizers to help plants grow faster. But these fertilizers can dissolve too quickly in water or soil, making plants take in too many nutrients. This can hurt the environment by causing run-off, leaching, and turning nutrients into gas. To fix this, we need materials that can hold water and let nutrients out slowly.One solution is slow-release fertilizer hydrogels, or SRFHs. These are like natural plant food that gives crops water and nutrients over time. They help plants grow better and produce more food. This review looks at how SRFHs are made, what they can do, and how they work in smart farming. It also talks about how soil microbes react to these fertilizers and what the future might hold for SRFHs. SRFHs are made by mixing different things together. They can hold a lot of water and release nutrients slowly. This is good for plants and the environment. Farmers can use less fertilizer and still get good results. SRFHs can also help soil microbes stay healthy. In the future, SRFHs could be even better. Scientists are working on making them more effective and easier to use. This could help farmers grow more food with less harm to the environment.
