Surface runoff and relief
This refers to the flow of rain or meltwater over soil surfaces, governed by the field's slope, topography, and the physical characteristics of the terrain.

Surface runoff dictates soil moisture distribution and the potential for erosion. Managing the relief is essential to retain water within the field, preventing the loss of topsoil and the leaching of essential nutrients into low-lying areas.
Practitioners utilize contour farming, terracing, and minimum tillage techniques to manage water velocity effectively. Proper layout of drainage systems is vital on sloping terrain to mitigate soil degradation and prevent gully formation.
A common error is plowing along the slope, which significantly increases erosion risks. Furthermore, neglecting field micro-topography during sowing leads to uneven crop development, characterized by waterlogging in depressions and moisture deficits on ridges.
