Growing up in disadvantaged communities can take a toll on children, with greater stress leading to mental health issues and delays in psychological development. But a decade’s worth of research suggests there’s an effective and nearly free remedy that may level the playing field with their advantaged counterparts: time in nature. 

Tile drainage is common in U.S. Midwest agricultural fields, helping to remove excess water and aerate the soil. While the practice enhances crop productivity, it can cause phosphorus to leak into nearby waterways, where it contributes to harmful algal blooms. Directing tile-drain runoff through a structure filled with biochar – a form of charcoal produced from organic waste – provides a potential remedy for phosphorus pollution, but the method is novel and not fully explored.

Conservation tillage practices, such as no-till and reduced till, are critical for sustainable agriculture, and they are gradually becoming popular with farmers across the Midwest. Monitoring tillage usage can provide insights into soil health, water levels, and nutrient loss, as well as guide management and policy decisions. 

Last week, the U.S. Department of Agriculture announced a substantial reorganization of the Forest Service, moving its headquarters to Salt Lake City, Utah, and closing its existing regional offices. According to the announcement, the move is designed to move leadership “closer to the forests and communities it serves.” 

As winter comes to a close, many people look forward to warmer temperatures and spring blooms, but for land managers working to preserve or restore oak-dominated forests, it is prescribed burn season. Fire brings more light into forests, which is crucial for young oak tree growth, but many land managers are concerned about how non-native plants affect fire intensity and young tree survival rates.

Hydrological models represent water movement in natural systems, and they are important for water resource planning and management. But the models depend on reliable input data for weather factors, and precipitation can be very difficult to measure and represent accurately.

In a world where increasing demands for food security and energy strain existing resources, scientists are looking for new ways to maximize both. One potential option, agrivoltaics, integrates solar photovoltaics with crops. A new study examines the agricultural and economic trade-offs that come with installing solar arrays on working farms across the Midwest.

The soil microbiome is critical for the ecosystem, and agricultural practices that promote microbial diversity can support plant health and help protect against pests. But it is unclear which practices are most beneficial, and what motivates farmers to choose them.

Corn bred with genes from wild relatives can reshape soil microbial communities and reduce nitrogen loss — with no yield reduction — according to new research from the University of Illino

The ubiquitous plastic beverage bottle makes up about half of plastic waste collected for recycling in the U.S. Most recycled plastic is processed domestically, but a portion is traded overseas.
