Creation of furrow micro-catchments using an ox-driven plough is a traditional seedbed preparation practice among agropastoral communities inhabiting arid and semi-arid environments in Kenya. The process involves minimal soil disturbance by intentionally creating shallow furrows (about 20 cm depth) using an ox-driven plough. Oxen commonly used predominantly have a light and bright skin coat. This is aimed at reflecting away excess heat from the sun. Consequently, the oxen are less fatigued and can therefore plough for a longer period of time. The furrow microcatchments are intentionally created across the slope to harvest rainwater to prolong water availability for seed germnination and subsequent growth and development of emerging seedlings. Furthermore, the ox-plough breaks the soil hard-pan common in dryland environments. Therefore, the microcatchments also facilitate seedling root penetration to the lower horizons. Prolonged water availability, especially in dryland environments, promotes growth and development of fast growing and early maturing drought tolerant crops and indigenous pasture production, consequently better crop yields and pasture production.

Rainwater harvested along micro-catchments improves soil moisture content and prolongs water availability.
Micro-catchments reduce the kinetic energy of rainwater by trapping runoff, thus reduce soil loss.
Damage on neighbours fields is greatly reduced. Micro-catchments trap rainwater, thus reduces runoff which might damage a neighbours field, especially located downslope.
Damage on public and private roads is greatly reduced. Micro-catchments trap rainwater, thus reduces runoff which might damage infrastructure
