Artificial fertilisers provide short-term gains but lead to severe long-term disadvantages, including soil toxicity and reduced fertility. In contrast, organic fertilisers offer an affordable alternative that enhances soil health and agricultural output over time. Sourced from minerals, animal manure, sewage sludge, and plant residues, these organic inputs contribute valuable organic matter to the soil. Their application improves essential soil characteristics, notably soil structure, texture, aeration, and water retention capacity, whilst also promoting robust root development. Consequently, adopting integrated nutrient management strategies that combine scientific management with diverse organic inputs supports sustained soil productivity. This approach fosters optimum plant growth, higher crop yields, and improved produce quality on a continuous, long-term basis.
Long-term reliance on artificial fertilisers can harm soil fertility and create toxicity, threatening sustainable food production. Organic fertilisers present a cost-effective solution that replenishes organic matter, strengthens soil structure, and enhances water retention. By adopting integrated nutrient management based on organic inputs, growers can maintain healthier soils and sustain crop yields and crop quality over time.
The abstract outlines broad agronomic principles rather than a proprietary product or technology. The underlying practices could be applied by agricultural producers and waste managers utilising animal manure, crop residues, or sewage sludge within integrated nutrient management programmes. However, as this is a general conceptual review recommending the appropriate use and scientific management of existing organic sources, the abstract does not indicate a specific commercial development pathway or readiness level.

As a key component of agricultural sustainability, organic fertilizer contributes greatly to improving soil fertility. Therefore, the objective of this review is to revise the role of organic fertilizer on agricultural product and productivity. The newly sourced artificial fertilizer had a short-term benefit, but it had severe long-term side effect such as soil toxicity and decline soil fertility. Afterward, the idea of organic farming was acceptable to developed organic agriculture system. The use of organic fertilizers has advantage of being cheap, improving soil structure, texture and aeration increasing the soils water retention abilities and stimulating healthy root development. Organic fertilizer has many sources such as minerals, animal source, sewage sludge and plant. Vegetables, animals and residue materials had a contribution to improve soil organic matter content in soil. Therefor it is recommended that, using integrated nutrient management is a continuous improvement of soil productivity on longer term basis through appropriate use of organic fertilizers (i.e. animal manure, plants residue and sewage sludge) and their scientific management for increments of optimum growth, yield and quality of different crops.
