What Sustainable Practices Are Common in Generational Farming?

Passing down the family farm to future generations is at the heart of the American farming industry. While large corporate “factory farms” often make the news as the face of the farming industry, you might be surprised to learn that as of 2021, 96 percent of US farms were owned by families, with 88 percent of them being small family farms.

The families running these farms work hard to preserve land and resources for future generations to make a living off of and enjoy. That’s why many generational farms are at the forefront of sustainable farming practices, focusing on maintaining soil health, conserving water, and protecting biodiversity.

Sustainability isn’t just important for the success of current farmers. It’s also critical for future generations of farmers—and for the planet, too.

What Is Generational Farming?

Generational farms are those that have been passed down through multiple generations of a family. Generational farms often focus on the long-term financial and environmental sustainability of their operations. Water conservation, soil management, and preserving biodiversity are all top priorities.

Farms that have been in the family for decades are often run by people who have a deep knowledge of their land. They understand how to maximize their yields while minimizing their impact on the surrounding environment. For this reason, many generational farms are at the forefront of adopting new practices and technologies that help them work together with natural resources.

Crop Rotation

Crop rotation is one of the most important sustainable farming techniques. It involves alternating the crops planted in a field to maintain the soil’s nutrients and reduce pests and disease.

Potatoes, for instance, need a high quantity of nutrients, like nitrogen, potassium, and phosphorus, in order to grow. If a farmer were to plant potatoes in the same field every single year, the soil would soon become depleted of these important nutrients.

While synthetic fertilizers can be added to compensate, crop rotation is a more natural way to ensure that plants grow healthier, without the extra cost or environmental impact of chemical additives.

Growing a cover crop can also help naturally break cycles of pests, weeds, and diseases, which reduces the need for chemical pesticides.

What type of crops do farmers use as cover crops?

It largely depends on the climate they’re working in and the crops they’re growing. A potato farmer might opt to use legume crops like clover or peas, which are great for introducing nitrogen back into the soil. Other farmers may use a mixture of rye, wheat, oats, turnips, or mustard.

Soil Conservation

Soil is the lifeblood of generational farmers and the agricultural industry as a whole, retaining water and holding all the nutrients plants need to grow. But erosion and nutrient depletion can have a serious impact on the health of the soil, the quality of crops produced, and the overall financial viability of a farm. To help combat these issues, many generational farms turn to sustainable soil conservation practices.

Traditional plowing can disrupt soil structure, which can lead to future erosion and excess water runoff. As a result, many farmers have moved to no-till or reduced-till farming, which preserves the health of the land and minimizes soil disturbance.

Many farmers also compost. This involves recycling all the organic matter produced by the farm into a natural, nutrient-rich fertilizer. Compost returns vital nutrients back to the soil, without the added cost or environmental impact of chemical fertilizers.

Water Management

Growing healthy crops would be impossible without proper, sustainable water management. Even small family farms can grow hundreds of thousands of pounds of produce every year—and that requires a lot of water.

Drip irrigation has been around for centuries and is one of the most efficient ways to water crops. It minimizes evaporation and runoff by delivering water directly to a plant’s roots. Farmers who need to keep large fields watered also use center-pivot irrigation systems. These are large sprinklers that efficiently distribute water to a whole field.

Water management isn’t just about irrigation. It’s also helpful for farmers schedule watering for when their plants really need it. Soil moisture sensors and weather forecasting tools take into account the moisture currently present in the soil and temperature levels to help ensure that crops receive the right amount of water every day.

Biodiversity Protection

North America is an incredibly biodiverse place, with millions of species working together to keep ecosystems balanced. But protecting wildlife while also supporting farmers isn’t always easy.

Animals’ needs and farmers’ needs don’t have to be at odds, though. Many local farmers already recognize the importance of maintaining biodiversity and help preserve wetlands and wooded areas for pollinators, birds, and fish.

Farmers using sustainable practices also know that relying heavily on synthetic fertilizers and herbicides can lead to runoff that negatively impacts local water sources, wildlife, and beneficial insects. While these products can help crops grow faster, farmers can achieve the same effect through sustainable practices like crop rotation and soil conservation.

End Goal: Long-Term Agricultural Sustainability

Generational farming goes beyond simply growing and selling crops to make a profit. It’s about passing traditions and practices on from grandparents to parents to children. It’s about sustainably preserving a valuable way of life that’s been a part of the family for generations.

Sustainable agriculture isn’t new. But more than ever before, family-run farms are committing to long-term sustainability practices to adapt to changing environmental conditions and maintain food security for their community.

Sustainable farming is more than just an ethical responsibility. It’s a necessity that preserves America’s farmland and ensures that future generations will be able to use all the resources that have been passed down to them.
