All Flashcards
Why is soil health important?
Healthy soil supports plant growth, prevents erosion, and contributes to overall ecosystem health.
How does contour plowing prevent soil erosion?
By following the land's natural curves, it minimizes soil disturbance and reduces water runoff, thus preventing erosion.
What are the benefits of no-till agriculture?
Reduces erosion, keeps soil structure intact, and can improve water infiltration.
How do windbreaks protect soil?
They act as a barrier, reducing wind speed and preventing wind erosion of topsoil.
What is the purpose of terracing on steep slopes?
Creates flat areas to reduce water runoff and soil erosion, making it possible to cultivate otherwise unusable land.
How does crop rotation improve soil health?
Different crops have different nutrient needs and can replenish specific nutrients in the soil, preventing depletion.
What role do legumes play in crop rotation?
Legumes add nitrogen back into the soil, which is essential for plant growth and reduces the need for synthetic fertilizers.
How does green manure benefit the soil?
Adds organic matter and nutrients back into the soil, improving its structure and fertility.
Why is calcium important for plant growth?
Calcium is an essential nutrient for cell wall development and overall plant health.
What are ecosystem services?
The many and varied benefits that humans freely gain from the natural environment and from properly-functioning ecosystems. Soil health is a crucial ecosystem service.
Define sustainable agriculture.
Using resources wisely to meet current needs without compromising future generations' ability to meet their own needs.
What is contour plowing?
Plowing with the land's natural curves to minimize soil disturbance and erosion.
Define no-till agriculture.
An agricultural technique that minimizes soil preparation and disturbance.
What are windbreaks/shelterbelts?
Rows of trees or bushes planted to block the wind and protect soil from erosion.
Define terracing.
Creating flat steps on hillsides to reduce soil loss on slopes.
What is strip farming?
Alternating rows of crops with unplanted areas to prevent erosion and improve soil health.
Define crop rotation.
Planting different crops in a sequence to improve soil health and fertility.
What is green manure?
Letting leftover crop parts decompose in the soil to add nutrients.
Define pasture rotation.
Rotating grazing areas for livestock to prevent overgrazing and maintain pasture health.
What are hedgerows?
Windbreaks planted at the edges of fields for extra protection against wind erosion.
How can contour plowing promote sustainability?
Reduces soil erosion, conserves water, and maintains soil fertility, leading to long-term agricultural productivity.
How does no-till agriculture contribute to sustainable farming?
Minimizes soil disturbance, reduces erosion, conserves soil moisture, and can sequester carbon in the soil.
How do windbreaks support sustainable agriculture?
Protect soil from wind erosion, provide habitat for beneficial insects and wildlife, and can improve microclimate for crops.
How does terracing help achieve sustainable land use?
Reduces soil erosion on steep slopes, allows for cultivation of otherwise unusable land, and conserves water.
How does crop rotation enhance sustainability?
Improves soil health, reduces pest and disease outbreaks, and minimizes the need for synthetic fertilizers and pesticides.
How can green manure contribute to sustainable soil management?
Adds organic matter and nutrients to the soil, improving its structure, fertility, and water-holding capacity.
How does pasture rotation promote sustainable livestock management?
Prevents overgrazing, maintains pasture health, and reduces soil erosion and nutrient runoff.
How can integrated pest management (IPM) support sustainable agriculture?
Reduces reliance on synthetic pesticides, promotes biodiversity, and minimizes environmental impacts.
How does water conservation contribute to sustainable agriculture?
Reduces water scarcity, minimizes irrigation costs, and prevents water pollution from agricultural runoff.
How can reducing food waste support sustainable agriculture?
Decreases demand for agricultural production, reduces resource use, and minimizes environmental impacts associated with food production and disposal.
