abstract
Hydroponic farming has garnered interest as a sustainable agriculture method because of its ability to produce higher yields and efficiently use resources. This abstract investigates the benefits associated with utilising agricultural waste in hydroponic systems. Hydroponic systems can optimise resource efficiency and lessen environmental effect compared to conventional soil-based farming by recycling materials like Stalks and leaves left over from harvests. By decreasing dependency on artificial fertilisers and protecting natural resources, this approach offers a sustainable substitute. The viability and advantages of using crop residues as a component of hydroponic medium in sustainable production systems are examined in this abstract. When handled appropriately and incorporated into hydroponic systems, crop residues which are usually regarded as waste can function as beneficial organic substrates. These crop residues improve the growing media general fertility and health by contributing vital nutrients, organic matter, and microbial diversity. Reducing the use of synthetic fertilisers reduces the carbon footprint associated with their manufacturing and transportation, as well as nutrient runoff. By repurposing agricultural by-products, using crop wastes may also reduce production costs and support the circular economy. Crop residue also minimise soil erosion and the requirement for traditional tillage, which in turn improves soil health and biodiversity when used in hydroponic media. Enhancing nutrient release from crop leftovers and creating specialised hydroponic systems that can efficiently use a variety of agricultural wastes would require more study. The incorporation of agricultural leftovers into hydroponic systems, however, is an important step in improving food production's sustainability and resistance to global issues like resource shortages and climate change. Crop residue-based hydroponics has the potential to completely transform agriculture and open the door to a more sustainable future with further research, innovation, and teamwork efforts.
