Agricultural Experts Advocate for Soil-Specific Fertiliser Strategies to Enhance Crop Yields

In a recent meeting at the 2026 Nigeria Fertiliser Summit held in Abuja, agricultural experts urged a departure from blanket fertiliser recommendations, advocating for soil-specific applications to boost crop yields. The summit, co-organized by the Institute of Agricultural Research and Training (IAR&T) and the Fertilizer Producers and Suppliers Association of Nigeria (FEPSAN), brought together stakeholders to discuss the critical role of phosphorus in crop production and food security.

Presenting findings from the Regional Hub for Fertilizer and Soil Health for West Africa and the Sahel, experts revealed that the phosphorus requirements for maize and rice in northern Nigeria can vary dramatically, from zero to over 60 kilograms of phosphorus pentoxide per hectare. This variance underscores the necessity for farmers to understand their soil's unique properties and nutrient requirements rather than relying on uniform fertiliser practices that may not suit their specific agricultural conditions.

Prof. Vincent Aduramigba-Modupe, a soil scientist and modelling expert at IAR&T, emphasized that enhancing agricultural productivity is not solely about increasing fertiliser input. “Farmers must be equipped with the knowledge of their soil’s characteristics to make informed decisions about nutrient application,” he stated, highlighting the potential cost savings and improved productivity that can be achieved through tailored fertiliser strategies.

With phosphorus playing a crucial role in root development, crop growth, and grain formation, the availability of this nutrient is heavily influenced by soil conditions and farming practices. Experts warn that without a shift towards more personalized fertiliser recommendations, farmers may continue to incur unnecessary costs and experience suboptimal yields.

This call for change comes at a pivotal time in Nigeria's agricultural sector, where the need for increased food production is more pressing than ever. As the nation grapples with food security challenges, adopting soil-based fertiliser strategies could prove essential in enhancing agricultural sustainability and productivity.
