Pennsylvania’s agricultural landscape is a complex tapestry of high-acreage commodity production and specialized, high-value crops, establishing the state as a significant contributor to the nation’s food supply. With a deep history of farming and a varied geography, the commonwealth consistently ranks high in national agricultural output. This diversity allows Pennsylvania growers to produce everything from feed grains to gourmet mushrooms and orchard fruits.
Pennsylvania’s Major Field Crops
Large-scale commodity crops form the wide base of Pennsylvania’s farming industry, dedicating millions of acres to high-volume production. Corn is the most widely planted field crop, with over a million acres typically harvested annually. Most of this corn is field corn, used as feed for the state’s substantial livestock and poultry industries. About two-thirds of the corn acreage is harvested as grain, while the remaining third is chopped for silage, a fermented feed that provides nutrition to dairy and beef cattle throughout the year.
Soybeans are another substantial field crop, often grown in rotation with corn to help maintain soil health and manage pests. These oilseeds are primarily utilized in animal feed rations and for processing into various food and industrial products. Winter wheat, oats, and barley are also cultivated, though on smaller acreage, and are generally sold to local feed mills for livestock consumption.
Hay is also a foundational crop, covering a large number of acres to support the state’s extensive dairy and livestock populations. Farmers harvest various types, including protein-rich alfalfa hay and other grasses like timothy, which serve as bulk forage for animals. The production of these feedstuffs is directly tied to the commonwealth’s strong animal agriculture sector.
Specialty Produce and High-Value Horticulture
Beyond the field crops, Pennsylvania is renowned for its specialized produce and high-value horticultural products. The state is the unquestioned leader in mushroom production, supplying the majority of all cultivated mushrooms grown in the United States. This specialized industry is heavily concentrated in southeastern Pennsylvania, particularly in Chester County.
Tree fruits thrive due to the temperate climate and rich soils. Pennsylvania ranks within the top five states for the production of both apples and peaches. Adams County is a major apple-growing region, with a significant portion of the harvest dedicated to processing into juice, cider, and sauces. Grapes are another important fruit, supporting a growing local wine industry, with the state maintaining a top-four national ranking.
Small fruits and processing vegetables are grown for both wholesale and direct-to-consumer markets. The state’s floriculture sector, encompassing greenhouse and nursery products, ranks first in the nation for the number of floriculture businesses.
Small Fruits and Vegetables
- Small fruits include blueberries, raspberries, and strawberries.
- Processing vegetables include snap beans, tomatoes, and potatoes.
Climate and Geographic Factors Supporting PA Agriculture
The ability to grow such a diverse range of crops is largely due to Pennsylvania’s favorable geography and temperate climate. The state is situated within a humid continental climate zone, which provides four distinct seasons and generally adequate rainfall for crop cultivation. Annual precipitation typically averages around 41 inches, which minimizes the need for widespread irrigation across most of the state.
There are regional differences. Lowland areas in the south have longer growing seasons and milder winters, supporting the more tender specialty crops. Conversely, the upland regions experience shorter, cooler seasons, which favors hardier field crops and forage production.
A major factor in the state’s productivity is the presence of Alfisols, highly fertile soils formed primarily over limestone bedrock. These limestone-derived soils, particularly prevalent in the southeast and central valleys, provide good water retention and a beneficial alkalinity for many types of crops, creating the foundation for intense agricultural activity in areas like Lancaster County.
Economic Contribution and Key Producing Regions
Pennsylvania’s agricultural sector provides a substantial economic engine for the commonwealth, contributing tens of billions of dollars annually to the state’s gross product. The industry supports hundreds of thousands of jobs across farming, processing, and distribution. This financial output comes from a geographically concentrated industry, with production heavily centered in specific regions.
Lancaster County consistently leads the state in total agricultural sales and output, serving as the epicenter of farming activity due to its highly productive limestone soils and cultural heritage of intensive cultivation. Other counties, such as York, Chester, and Franklin, also rank highly in various crop categories.
The state’s strong agricultural base is also recognized nationally for its direct-to-consumer sales, ranking second only to California. This concentration of activity supports a strong network of farm stands, farmers’ markets, and local food systems that connect growers directly with consumers.
