Mathematical modelling approach to understanding the effect of Mg-rich synthetic gypsum used as fertilizer on growth of Hevea brasiliensis in acid soils (2025)
Journal Article

Knowledge of plant growth dynamics is essential where constraints such as COVID-19 lockdown restrictions have limited its field establishment. Thus, modeling can be used to predict plant performance where field planting/monitoring cannot be achieved....

Real-time assessment and measurement of soil carbon in agricultural land of Gloucestershire at a farm-scale (2024)
Presentation / Conference Contribution

Previous research promoted carbon assessment and flow of human and natural capital to remediate atmospheric carbon emissions on farms. However, differences among types of agricultural land are often not included as part of measurement methods. This s...
