What is the Difference Between a Horticulture Degree and an Agriculture Degree?

The disciplines of horticulture and agriculture are often closely linked, but they serve different functions within society. Plants are a source of food, clean air and beauty, and there are many people who seek to find ways to enhance their presence on the earth. This type of herb cultivation is known as horticulture, and the results of this practice are often used to help farmers improve agricultural activities like growing food crops for human and animal consumption. Your career choice will ultimately dictate which of the degree programs you will choose. Here are some of the key differences between university level horticulture degree programs and those for agricultural science, some examples of courses taken in each discipline and the types of agriculture and horticulture internships that are available for students.

Degree Programs for Horticulture and Agricultural Science

Most horticulture degree programs emphasize the study of plant health, pest control and nutrient content. Students work with plants that are grown in small spaces to study what is needed for them to thrive. The programs are heavily science based and include laboratory testing of plants, the evaluation of soil properties and real world field work projects that address modern issues like the use of natural methods to repel the insects that destroy cultivated plants. Within agricultural science programs, many students are able to study the technical aspects of food crop production and livestock maintenance as well as the business of marketing and distributing food products to businesses and consumers.

Course Curricula for Horticulture and Agricultural Science Degree Programs

Some of the most common course topics that are included in most horticulture degree programs are landscape and garden planning, plant pathology and vegetable gardening. Nearly all commercial and residential real estate owners attempt to add curb appeal and beauty to their properties through the use of proper landscaping techniques. These are the principles and procedures that are taught within many horticulture programs. Diseased plants are unsightly, and they represent wasted money and natural resources. Classes taught within horticulture programs address the identification of plant diseases, plant treatment options and methods to prevent the spread of infections. Horticulture courses also teach students the essential principles for starting and maintaining food producing vegetable gardens. They learn how these gardens should be set up, the different techniques for cultivating small space gardens and the necessary nutrients that should be present in the soil while plants grow. Some of the courses taught within agricultural science programs are organic farming and gardening, environmental law and environmental economics. Organic farming courses focus on ways to cultivate food crops with minimal use of synthetic fertilizers and insecticides based on governmental regulations and industry standards. Environmental law courses address the legal obligations of farmers relating to safe maintenance of lands that are used for food crops. Aspiring farmers learn about the factors that affect crop prices and farm profits when they take agricultural science courses on environmental economics.

Available Internships for Horticulture and Agricultural Science Students

Horticulture students can gain valuable work experience through internships with government agencies and private businesses. For example, the Smithsonian Gardens organization provides internships for students and recent horticulture graduates to work in one of the most famous gardens in the nation. The same type of supervised field work assignments are available to agricultural science students. An organization called World Endeavors helps to place agricultural science students into internships in international locations where they analyze farming techniques and recommend improvements based on scientific research.


Interest in the study of plants for their ecological value and as food sources has increased over the years. The current post industrial society has produced people who are concerned with the safety and nutritional value of their food supply, and these people are increasingly choosing to get their dietary needs met directly from plants. Subsequently, the degree programs for both horticulture and agriculture teach important concepts that affect the well being of people groups around the world.
