Cover Cropping-Mediated Regulation of Phyllosphere Microbial Health and Rice Yield.

Soil Health
Planting a simple off-season ground cover—clover, rye, or vetch—before your rice or vegetable beds can seed the leaf surfaces of your next crop with beneficial microbes that crowd out pathogens before they take hold.
Scientists discovered that planting cover crops (plants grown in the off-season to protect and enrich soil) changes which tiny organisms live on rice leaves. These leaf-surface microbes, when shifted by cover cropping, help rice plants stay healthier and produce more grain. It's a chain reaction that starts in the soil and ends up improving the crop above ground.
Key Findings
Cover cropping significantly altered the composition of microbial communities on rice leaf surfaces (the phyllosphere), not just in the soil.
The microbiome changes on rice leaves were associated with reduced disease pressure and improved plant health indicators.
Rice plots preceded by cover crops showed measurable yield increases compared to plots without cover crops.

Growing cover crops before rice seasons reshapes the microbiome living on rice leaves, and that microbial shift correlates with healthier plants and higher grain yields.

Rice is a cereal grain and in its domesticated form is the staple food of over half of the world's population, particularly in Asia and Africa. Rice is the seed of the grass species Oryza sativa —or, much less commonly, Oryza glaberrima. Asian rice was domesticated in China some 13,500 to 8,200 y...
