Which of the following methods is NOT typically used for planting seed?

Hand planting is not typically considered a method for planting seed on a larger scale, especially in the context of erosion control and land restoration, where the focus is often on efficiency and coverage. While it can be useful for selective planting or in smaller areas, it is not practical for extensive applications or sites that require significant seed dispersal over large areas.

Mechanical drills, hydraulic methods, and broadcasting are more commonly employed techniques for seed planting. Mechanical drills allow for precise placement and depth control of seeds, which is essential for optimal germination and growth in many contexts. Hydraulic methods are effective for quickly and evenly distributing seeds along with water or mulch, which can be especially beneficial on slopes or in hard-to-reach areas. Broadcasting involves spreading seeds over the surface, either by hand or mechanically, and is a widely-used method for establishing ground cover quickly, particularly in large regions.

Thus, while hand planting has its merits in certain scenarios, it is less applicable in comprehensive erosion and sediment control strategies where uniformity and coverage are critical.
