Impacts of Agricultural Practices - AP Environmental Science

Soybeans are commonly genetically modified. Often modified for herbicide resistance and pest tolerance.

IPM is an eco-friendly approach to pest control. Combines biological, cultural, and chemical controls strategically.

Agroforestry integrates trees and shrubs into crop systems. Combines forestry and farming for multiple benefits.

Composting improves soil fertility. Organic matter adds nutrients and improves soil structure.

Overgrazing can lead to desertification. Excessive livestock grazing removes vegetation and degrades soil.

Terracing prevents soil erosion on slopes. Creates flat platforms on hillsides to reduce water flow.

Monoculture can lead to soil degradation. Lack of crop diversity depletes specific nutrients repeatedly.

Methane emissions contribute to global warming. Methane is a potent greenhouse gas from livestock digestion.

Agroforestry integrates trees and shrubs into crop systems. Combines forestry and farming for multiple benefits.

Buffer strips reduce agricultural runoff. Vegetation zones filter nutrients before reaching waterways.

Urbanization reduces available agricultural land. Cities expand onto farmland, converting productive soil.

Organic fertilizers enhance soil structure. Natural materials improve soil texture and water holding.

Irrigation alters natural water flow patterns. Diverts water from natural streams and groundwater.

Precision agriculture aims to optimize resource use and crop yields. Uses technology to apply inputs only where and when needed.

Agroforestry sequesters carbon. Trees capture and store atmospheric carbon dioxide.

Intercropping increases biodiversity. Growing multiple crops together creates diverse habitats.

Windbreaks reduce wind erosion and protect crops. Tree or shrub rows create barriers against wind damage.

Pesticides can lead to water contamination. Chemicals can runoff into groundwater and surface water.

Biological control is an alternative to chemical pesticides. Uses natural predators and parasites to control pests.

Drip irrigation helps conserve water. Delivers water directly to plant roots, minimizing waste.

Cover crops prevent erosion and improve soil health. These plants protect bare soil between growing seasons.

Heavy machinery can compact soil, reducing aeration. Weight compresses soil particles, reducing pore space.

Crop diversity reduces pest and disease risks. Multiple varieties prevent widespread crop failure.

Fertilizer overuse can lead to nutrient pollution. Excess nutrients cause algal blooms and water quality issues.

Improved irrigation management can reduce soil salinization. Better drainage and water quality prevent salt buildup.

Methane is primarily released from rice paddies. Anaerobic decomposition in flooded fields produces methane.

A food desert is an area with limited access to affordable, healthy food. These areas lack grocery stores with fresh produce.

No-till farming reduces soil erosion. Leaves crop residue on surface to protect soil.

Crop rotation reduces soil erosion and nutrient depletion. Different crops restore nutrients and break pest cycles.
