What Not To Plant With Soybeans

Certain plants can have negative effects on soybeans, hindering their growth and productivity. In this article, we will explore some of the plants that should not be planted alongside soybeans and the reasons behind it.

Corn: Planting corn near soybeans can lead to increased competition for nutrients, water, and sunlight. Both crops have similar requirements, and when planted together, they can limit each other’s access to essential resources, resulting in reduced yields for both.

Sunflowers: While sunflowers are visually appealing and beneficial for pollinators, they can negatively impact soybeans. Sunflowers have a dense canopy that can shade soybeans, reducing their access to sunlight. Additionally, sunflowers can attract pests that may also harm soybeans.

Cotton: Cotton plants are known to be susceptible to certain diseases and pests, which can easily spread to soybeans if planted in close proximity. This can lead to significant crop losses and increased management efforts to control the spread of diseases and pests.

Tomatoes: Tomatoes are heavy feeders and require high levels of nutrients from the soil. When planted near soybeans, they can deplete the soil of essential nutrients, leaving soybeans nutrient-deficient and stunting their growth.

Potatoes: Similar to tomatoes, potatoes are also heavy feeders and can compete with soybeans for nutrients. Planting potatoes near soybeans can result in nutrient deficiencies and reduced yields for both crops.

Peas: Peas are leguminous plants, just like soybeans, and they both have the ability to fix nitrogen from the atmosphere. However, planting peas near soybeans can lead to excessive nitrogen fixation, which can result in imbalanced nutrient levels and reduced yields.

Wheat: Wheat and soybeans have different growth habits and nutrient requirements. When planted together, wheat can shade soybeans, limiting their access to sunlight. Additionally, wheat can attract pests that may also harm soybeans.

Lettuce: Lettuce is a shallow-rooted plant that can compete with soybeans for water and nutrients. Planting lettuce near soybeans can result in water and nutrient stress for soybeans, leading to reduced growth and yields.

Carrots: Carrots have a long taproot that can penetrate deep into the soil, competing with soybeans for water and nutrients. Planting carrots near soybeans can result in water and nutrient deficiencies for soybeans, affecting their growth and productivity.

Onions: Onions are known to release certain compounds that can inhibit the growth of neighboring plants, including soybeans. Planting onions near soybeans can lead to stunted growth and reduced yields for soybeans.

Radishes: Radishes are often used as a cover crop to improve soil health. However, when planted near soybeans, radishes can compete for resources and limit soybean growth. Additionally, radishes can attract pests that may also harm soybeans.

Cabbage: Cabbage plants can release certain compounds that can inhibit the growth of nearby plants, including soybeans. Planting cabbage near soybeans can result in stunted growth and reduced yields for soybeans.
