Decline in Soil pH levels threatens agriculture in Mbogwe

GEITA: THE Department of Agriculture, Livestock and Fisheries in Mbogwe District has raised concerns over a decline in soil pH levels in the area, which is severely affecting crop cultivation.

The district’s soil health research programme has also highlighted a critical deficiency in essential plant nutrients, leading to reduced crop quality and production.

Mbogwe District Soil Health Research Programme Coordinator, Ms Magreth Mashauri, shared these findings during a recent presentation on soil testing.

She explained that the soil health initiative was launched in February 2024 following the provision of a soil testing machine by the Ministry of Agriculture.

“We collected 602 soil samples from 590 individuals across the 17 wards of Mbogwe District Council,” Ms Mashauri stated, adding that the analysis revealed significant deficiencies in phosphorus—a vital nutrient for plant root strength and water absorption.

The results also indicated that soil pH levels ranged between 5 and 7, which is below the optimal range for healthy crop growth.

This decline in soil health is affecting agricultural output across the district. Additionally, urea and potassium levels were found to be lacking, both crucial for strong plant growth.

Assistant Chief Agricultural Officer for Mbogwe District, Mr Simon Masanja, stressed the need for improved soil management. He advised farmers to apply 600-800 kg of compost manure per hectare and 50-80 kg of limestone per hectare to maintain soil fertility.

“We recommend the use of NPK, DAP and TSP fertilisers during planting, followed by the application of CAN fertilisers six weeks post-planting,” said Mr Masanja.

Speaking on behalf of the district commissioner, Mbogwe District Service Officer, Mr John Sungura, urged agricultural officers to use tablets provided for accurate data collection, which is critical for advancing the district’s agricultural sector.
