Over 500 Farmers Trained in Soil Health, Lime Application to Boost Yields in Northern Ghana
Tamale, July 15, 2025 — More than 500 smallholder farmers across the Northern and Upper West Regions have been trained in soil health restoration and effective lime application, through a collaborative initiative aimed at improving crop yields, input efficiency, and long-term agricultural resilience.
The training sessions, which took place from July 4 to 11 in the communities of Tumu, Sakai, Sang, and Sankpala, were organised by Agrisolve Ghana Ltd., in partnership with TerraCalco Ghana and Sesi Technologies, under the flagship Farmer School Project. The project seeks to address declining soil fertility by equipping farmers with practical, science-based tools and techniques.
At the heart of the demonstrations was FarmSense, a rapid soil testing system developed by Sesi Technologies. The tool provided real-time data on soil pH, nutrient levels, and organic matter, enabling farmers to make informed decisions on fertilizer use and soil amendments. Three FarmSense Soil Test Centres have now been established at Agrisolve’s GreenConnect hubs to ensure continued access throughout the season.
TerraCalco Ghana supplied over 50 metric tons of agricultural lime and led hands-on sessions on correct lime dosage, application timing, and integration with tillage practices. Farmers participated in live demonstrations comparing full-lime, half-lime, and control (no-lime) plots to observe first-hand the effects of lime on crop growth.
“These demonstrations are opening our eyes,” said Ruth Laadi Issah, a soybean farmer in Tumu. “I now understand why my fertilizer wasn’t working before — the soil was too acidic.”
Agrisolve Ghana, as the lead implementer, coordinated farmer mobilisation, technical facilitation, and partnerships with the Ministry of Food and Agriculture (MoFA). The company’s Project Manager, Raymond Enye, said the field days have sparked strong interest among both older and younger farmers.
“When farmers show up in these numbers and engage this deeply, it tells us they’re ready for change. We’re not just demonstrating — we’re driving adoption,” Enye added.
The training marks the beginning of a four-phase program that includes soil testing and lime application in July, fertilizer and pest management in August, crop growth monitoring in September, and yield comparisons at harvest between October and December.
The partners have called on government agencies, development organisations, and agribusinesses to support the project’s scale-up and help build a new model of soil-conscious, data-driven farming in Ghana’s rural north.
