The Soil and Environmental Sciences Research Centre (SESRC) of BNARI seeks to formulate innovative technologies that contribute towards the creation of a safe environment which also enhance sustainable agriculture practices for wealth generation by end users. To achieve this aim, SESRC engages in research activities that lead to a less disease-prone environment, improving growth and yield of food crops, encouraging the use of efficient irrigation practices and nutrients management strategies. Scientists at this centre also engage themselves in research activities in the area of nutrient mining from agricultural and municipal solid waste for sustainable agriculture. Ultimately, SESRC seeks to lead Ghana’s effort to create a sanitized environment and a sustainable approach to enhancing food security and the livelihood of her ever-growing population. The centre also houses the Compost Plant and the Black Soldier Fly (BSF) Facility, which are involved in producing nutrient-rich compost for organic crop production. Compost research from the Centre has led to the establishment of Compost Manufacturing Plants at Ashaiman by Safisana, and Nungua farms by IWMI.

Climate Smart Agriculture

Climate change is a reality and its effect may be detrimental to agricultural development in Ghana. Currently, the effect of climate change is localised and mostly lie within the range of natural climate change. However, in the longer-term climate change is likely to have a bigger effect on food supply than any other factor affecting agricultural productivity. Climate change is associated with drought and emerging new pests and diseases which pose greater more complicated challenge to food production. To mitigate against changing climate, BNARI is conducting series of research to develop crops which are resilient the effects of climate change. Principally, BNARI aims at developing drought tolerant plant species, use small-scale drip irrigation for vegetable production as a climate change mitigation, drought and water use efficiency studies in crops. The institute is also using neutron probe to study water use efficiency and soil-nutrient water management for crop production. This is done with the aim of obtaining the highest possible yield with as minimum fertilizer and water input as possible.

The centre also conduct research into nutrient use efficiency of high value crops such as (cabbage, cucumber, tomatoes, okro) and staple crops (cereals, cassava) as a climate change mitigation measure. Stable isotope techniques are used to assess the nutrient uptake by plants from the applied fertilizer. Based on the assessment results, the efficient use of the applied fertilizer by the plant is calculated and appropriate recommended rate is proposed for that specific plant. This helps to reduce nutrient losses to the environment and potentially decrease requirements for chemical fertiliser.

SERC employs the greenhouse method of growing tomatoes to shield the tomatoes from excess heat and unwanted pests which helps to grow crops all year round. This technique extends the growing season of prized crops
