Cover Crops: Good for Water Quality?

Cover crops have been a popular management strategy to reduce nutrient runoff from agriculture. However, evidence suggests that some cover crops may in fact release nutrients, instead of keeping them out of the water. One study explores whether five types of cover crops release phosphorus, and how that may impact water quality in the important Great Lakes region.

Dung Beetles and Soil Bacteria Promote Food Safety.

Having a diverse farm benefits everyone Not only will the soils be richer and the number of different crops grow higher but also diversity may also potentially be safer. By limiting the use of pesticides and maintaining various landscapes throughout a farmland, organic farming increases the number of insects, namely beetles, and bacteria that help break down potential pathogens before they infiltrate the growing crops. Jones and colleagues examined 70 vegetable fields throughout California and conducted several laboratory experiments to find that organic farms had richer, more diverse communities of beetles and soil bacteria that help breakdown foodborne pathogens.

Your resolution to eat healthy is saving the earth (more than you realize)

How much energy went into your last meal? According to a recent study, probably way more than you think. Food is responsible for 20-30% of global carbon emissions, but most people are terrible at judging the environmental cost of what they eat. Why is this? And what can we do?

Certified coffee farmers are environmentally friendly and compensated for their efforts: Imagination or reality?

Do you go to the grocery store and look for the Fair Trade™ or Rainforest Alliance™ certified coffee? Many consumers prefer to buy certified coffee because they believe there is an economic benefit to the farmer, environmental benefits, or both. However, do these certifications actually improve farmer income and/or protect important environmental services? A recent study conducted in Uganda suggests that farms that are double or triple certified for coffee production suffer trade-offs between economic and environmental benefits.

Seeing the Forest for the Trees

Satellites have changed our ability to see the globe. We can now use satellite data is to monitor change in the amount of land covered by forests, and determine the reasons for that change. In this article, we discuss recent findings global forest monitoring and the impact of supply chain decisions by corporate actors.

City phosphorus, country phosphorus: can we mitigate P in different environments?

Phosphorus is essential for life, but there is such thing as too much of a good thing. In excess, phosphorus can cause algal blooms, creating dead zones in bodies of water. How do we prevent phosphorus from entering water systems? Katrina Macintosh and her team did a comprehensive review to track phosphorus from diffuse sources to find out.

Near-death experiences: sublethal effects of pesticides on pollinating insects

Negative impacts of pesticides on pollinators can take different forms: direct kills on contact (called lethal effects) or indirect effects, through the pollinators’ abilities to reproduce (called sublethal effects). These sublethal effects are generally not spotted by regulatory bodies through traditional ecotoxicological tests, but have severe impacts on pollinator health.

Can solar farms help agricultural farms?

Electricity and food are two things each of us consumes every day. It is possible that by making smart choices, we can help grow more food while also generating electricity. Pollinating insects are an important part of agriculture in the US, and we can make electricity choices to increase the number of those insects near our farms.
