Microbes and plants: A dynamic duo

Certain bacteria living in sorghum roots work together with the plant to reduce drought stress, leading to overall plant success. The microbiome plays a critical role in determining crop productivity, and manipulating it may hold the key to developing crops that can thrive in harsh conditions.

Choosing the right cover crop to protect the soil

A recent study tested various cover crops to determine their effectiveness in protecting soil. While some cover crops had little impact, others showed promise in reducing erosion and nutrient loss. Researchers recommend choosing cover crops that can survive winter, grow well in spring, and hold onto soil for extended periods.

Wild cousins may help crops battle climate change

Researchers tested using wild crop relatives in breeding programs to improve crop resilience. The results showed that these relatives provided increased resistance to heat, drought, and some diseases, making them a promising approach to address climate change adaptation. However, breeders must also consider the potential impact on indu...

Climate change could increase rice yields

A new study suggests that climate change may increase rice yields in Japan and other tropical areas due to longer growing seasons. Researchers found that combining a normal harvest time with a high cutting height can lead to higher yields in rice ratooning, a farming practice where the crop is cut and regrown.

The story behind a uniquely dark, wetland soil

A team of scientists investigated an unusual wetland soil in California, discovering its peculiar properties that misled initial classification. By analyzing color, water content, vegetation, and chemical composition, they applied a new method to accurately classify the soil as hydric, crucial for conservation.

Putting zinc on bread wheat leaves

Researchers applied zinc foliar application to hard red spring wheat cultivars, increasing grain zinc concentration above the target level of 40 mg kg-1. The second application at flowering stage was necessary for this achievement, and price incentives are needed to motivate farmers to adopt biofortification.

GPS isn't just for road trips anymore

Researchers found that GPS-guided tractors can reduce overlap and gaps in field coverage by up to 6% and 16%, respectively, leading to increased crop production and environmental benefits. This technology has the potential to be adopted by small farms, which currently lag behind larger producers in terms of technology adoption.
