Companion Crops and Their Benefits

Study Notes

Benefits of Companion Crops

Increased biodiversity and ecosystem services
Improved soil health and structure
Enhanced nutrient cycling and uptake
Increased crop yields and quality
Reduced pest and disease pressure
Decreased need for fertilizers and pesticides
Creates a more resilient and adaptable agroecosystem

Trap Crops

A type of companion crop that attracts pests away from the main crop
Examples: nasturtiums to attract aphids, radishes to attract cucumber beetles
Can be used to reduce pest pressure on the main crop
Can also be used to monitor pest populations and detect early infestations

Pest Control through Companion Crops

Some companion crops repel or deter pests through chemical signals or physical barriers
Examples: basil repels aphids and mites, marigolds repel nematodes
Can be used to reduce the need for pesticides and maintain ecosystem balance
Can also be used to improve the effectiveness of integrated pest management (IPM) strategies

Polycultures

A type of companion cropping where multiple crops are grown together in the same bed
Can increase overall biodiversity and ecosystem services
Can improve resource use efficiency and reduce competition between crops
Examples: the "Three Sisters" method of growing corn, beans, and squash together
Can be used to create more resilient and adaptable agroecosystems

Nitrogen Fixation through Companion Crops

Legume companion crops (e.g. beans, peas, clover) have nodules on their roots that fix atmospheric nitrogen into a form usable by plants
Can reduce the need for synthetic fertilizers and improve soil fertility
Examples: planting nitrogen-fixing legumes with non-legume crops like corn or wheat
Can improve soil health and reduce environmental pollution

Benefits of Companion Crops

Companion crops increase biodiversity and ecosystem services, leading to a healthier and more resilient agroecosystem.
They improve soil health and structure by adding organic matter, reducing erosion, and increasing water retention.
Companion crops enhance nutrient cycling and uptake, making nutrients more available to the main crop.
They increase crop yields and quality by providing shade, support, and nutrients to the main crop.
Companion crops reduce pest and disease pressure by attracting beneficial insects and repelling pests.
They decrease the need for fertilizers and pesticides, reducing environmental pollution and promoting sustainable agriculture.

Trap Crops

Trap crops are a type of companion crop that attracts pests away from the main crop, reducing pest pressure and damage.
Examples of trap crops include nasturtiums, which attract aphids, and radishes, which attract cucumber beetles.
Trap crops can be used to monitor pest populations and detect early infestations, allowing for early intervention.

Pest Control through Companion Crops

Some companion crops repel or deter pests through chemical signals or physical barriers, reducing the need for pesticides.
Examples of pest-repellent companion crops include basil, which repels aphids and mites, and marigolds, which repel nematodes.
Companion crops can improve the effectiveness of integrated pest management (IPM) strategies by reducing pest pressure and promoting ecosystem balance.

Polycultures

Polycultures involve growing multiple crops together in the same bed, increasing overall biodiversity and ecosystem services.
This approach improves resource use efficiency and reduces competition between crops, leading to more resilient and adaptable agroecosystems.
Examples of polycultures include the "Three Sisters" method of growing corn, beans, and squash together.
Polycultures can be used to create more diverse and resilient agroecosystems.

Nitrogen Fixation through Companion Crops

Legume companion crops have nodules on their roots that fix atmospheric nitrogen into a form usable by plants, reducing the need for synthetic fertilizers.
Examples of nitrogen-fixing legumes include beans, peas, and clover, which can be planted with non-legume crops like corn or wheat.
Nitrogen-fixing companion crops improve soil fertility, reduce environmental pollution, and promote sustainable agriculture.
