• Lacewings: Lacewings are also predators of aphids, as well as other pests such as mites and caterpillars.
• Bees: Bees are essential pollinators for many fruits, vegetables, and flowers.
• Butterflies: Butterflies are also important pollinators, and they can also help to control pests by laying their eggs on the leaves of plants that are infested with pests.
• Moths: Moths are important pollinators for many night-blooming plants, such as orchids and evening primroses.

Nordhagen's research on beneficial insects is helping to shed light on the important role that these insects play in sustainable agriculture. By understanding how beneficial insects function, farmers can manage their fields to attract and support these insects, which can help to improve crop yields and reduce the need for pesticides.

3. Soil health

Soil health is the capacity of soil to function as a vital living ecosystem that sustains plants, animals, and humans. It is influenced by a variety of factors, including soil texture, structure, organic matter content, and microbial activity. Arlen Nordhagen is an ARS scientist who studies soil health. His research has shown that soil health is essential for sustainable agriculture.

• Soil texture and structure
  Soil texture refers to the size and shape of soil particles. Soil structure refers to the way soil particles are arranged. Both soil texture and structure can affect soil health. For example, sandy soils have large particles that allow water to drain quickly. This can make it difficult for plants to get the water they need. Clay soils have small particles that hold water tightly. This can make it difficult for air to reach plant roots.
• Organic matter content
  Organic matter is the decaying remains of plants and animals. It is an important component of soil health because it provides nutrients for plants and helps to improve soil structure. Soils with high organic matter content are more fertile and have better water-holding capacity than soils with low organic matter content.
• Microbial activity
  Microbial activity is the activity of microorganisms in the soil. Microorganisms are essential for soil health because they help to decompose organic matter, cycle nutrients, and suppress plant diseases. Soils with high microbial activity are more fertile and have better water-holding capacity than soils with low microbial activity.

Nordhagen's research on soil health is helping to develop more sustainable and environmentally friendly farming practices. By understanding how soil health can be improved, farmers can manage their soils to improve crop yields and reduce their environmental impact.

4. Sustainable agriculture

Sustainable agriculture is a farming system that aims to produce food and other agricultural products in a way that meets the needs of the present without compromising the ability of future generations to meet their own needs. It is based on the principles of ecology, economics, and social equity.

  Sustainable agriculture practices protect and improve the natural environment. For example, farmers may use cover crops to prevent soil erosion, or they may plant trees to provide windbreaks and wildlife habitat.
• Economic sustainability
  Sustainable agriculture practices are economically viable for farmers. For example, farmers may use crop rotation to improve soil fertility and reduce the need for fertilizers.
• Social sustainability
  Sustainable agriculture practices promote social equity and justice. For example, farmers may pay fair wages to their workers and provide them with safe working conditions.

Arlen Nordhagen is an ARS scientist who conducts research on sustainable agriculture practices. His research has shown that sustainable agriculture practices can improve soil health, crop yields, and farm profitability. For example, Nordhagen's research has shown that cover crops can increase soil organic matter content, improve soil structure, and reduce soil erosion.

By understanding how sustainable agriculture practices can improve soil health and crop yields, farmers can adopt these practices to improve their profitability and reduce their environmental impact.

5. Climate change

Climate change is a major threat to global food security. It is causing changes in temperature, precipitation, and extreme weather events, which can all have a negative impact on crop yields. Arlen Nordhagen is an ARS scientist who is conducting research on how to mitigate the effects of climate change on agriculture.

• Rising temperatures
  Rising temperatures can reduce crop yields by causing plants to grow too quickly, which can lead to lower yields and reduced quality. Nordhagen is researching ways to help crops tolerate higher temperatures, such as by developing heat-tolerant varieties and using irrigation to cool plants down.
• Changes in precipitation
  Changes in precipitation patterns can also have a negative impact on crop yields. Too much rain can lead to flooding, which can damage crops and make it difficult to harvest them. Too little rain can lead to drought, which can also damage crops and reduce yields. Nordhagen is researching ways to help crops tolerate drought, such as by developing drought-tolerant varieties and using irrigation to water crops during dry spells.
• Extreme weather events
  Extreme weather events, such as hurricanes, floods, and droughts, can also have a devastating impact on agriculture. These events can destroy crops, damage infrastructure, and make it difficult for farmers to get their products to market. Nordhagen is researching ways to help farmers prepare for and recover from extreme weather events, such as by developing disaster preparedness plans and providing farmers with access to financial assistance.

Nordhagen's research is helping to develop more sustainable and resilient farming systems that can withstand the challenges of climate change. By understanding how climate change is affecting agriculture, farmers can adapt their practices to reduce their vulnerability to climate change and continue to produce food for a growing population.
