Which kind of soil structure would be typical for a good seed bed?

Granular soil structure is ideal for a good seed bed primarily because it promotes optimal conditions for seed germination and root development. This structure consists of small, rounded aggregates that create a well-aerated environment with ample pore spaces. The granules allow for adequate water infiltration and drainage, which prevents waterlogging and encourages strong seedling growth.

Additionally, the loose nature of granular soil provides easy access for plant roots, allowing them to expand freely and effectively utilize nutrients. This structure also facilitates the movement of air, which is crucial for root respiration. In contrast, other soil structures, such as platy, blocky, and massive, tend to have limitations that can hinder seed bed quality. For example, platy structures may create compacted layers, while massive structures lack porosity and drainage, adversely affecting seedling establishment and growth.
