A Bauchi-based agricultural expert, Muhammad Kamal Adamu, has urged farmers to adopt the use of organic fertilizers, describing them as safer, healthier, and more environmentally friendly compared to chemical fertilizers.
Kamal, an extension agent with the Bauchi State Agricultural Development Programme (BSADP), made the call while featuring on Albarka Radio’s agricultural programme, Fam Beta Radio. He noted that organic fertilizers not only enrich the soil but also promote healthy crop production and protect human health.
He warned that continued use of chemical fertilizers poses long-term risks to the soil and the environment, due to harmful chemical components that degrade soil quality and contaminate the ecosystem.
Kamal demonstrated a simple and affordable method of producing fish-based organic fertilizer, explaining that a mixture of one kilogram of fish, one litre of water, and molasses produces an effective liquid fertilizer. He advised that the mixture be stored in a shaded area to ferment before use.
“After fermentation, the mixture should be sieved and applied to crops as it improves soil nutrients and enhances plant growth without negative environmental effects,” he explained. He added that any type of fish can be used, and if farmers only wish to fertilize their crops, the organic mix is sufficient. However, additional natural ingredients may be included if pest control is also desired.
On application frequency, the expert said organic fertilizers release nutrients gradually, suggesting two to three applications, and in some cases up to four or five times depending on soil condition. He advised farmers to assess soil quality before application for best results.
Kamal disclosed that many large-scale farmers have, over the last four to five years, successfully embraced organic fertilizers, often recording better outcomes than with chemical fertilizers.
He also highlighted other organic options such as banana peels, eggshells, poultry droppings, and green manure. According to him, water soaked with banana peels can be sprayed on crops to supply nutrients, while powdered eggshell—rich in calcium—benefits pepper and tomato cultivation.
Kamal emphasised that organic fertilizers remain cost-effective and environmentally friendly, and he encouraged farmers to adopt them for improved yields and long-term soil sustainability.
