Aerial imagery captures the distinct effects of two organic amendments—rice straw and biochar—applied at varying rates as a partial substitute for chemical fertilizer. Contrasts in canopy development demonstrate that both the type and the application rate of the amendment significantly influence rice growth patterns, highlighting the two amendments as potential sustainable fertilizer alternatives. Labels indicate one representative replication of a treatment from a randomized field trial.

The environment has just as much impact on a crop’s traits as its DNA. Ongoing research on how to incorporate this data to effectively select for the healthiest, hardiest, and highest-yielding crops was recently reviewed in The Plant Genome journal.
