What are agricultural practices aimed to maximize?
Crop yield and livestock productivity
Conventional farming relies on synthetic fertilizers and
pesticides
Sustainable farming emphasizes environmentally friendly methods like crop rotation and
natural pest control
.
Match the type of agriculture with its purpose:
Conventional Farming ↔️ High-volume crop production
Intensive Farming ↔️ Maximum land and output use
Sustainable Farming ↔️ Maintain soil health and biodiversity
Monoculture farming in conventional agriculture involves growing a single type of
crop
What is deforestation for farmland reducing?
Biodiversity and carbon sinks
Agricultural practices are major sources of water pollution due to fertilizers and animal
waste
High water usage in agriculture through irrigation can deplete
groundwater
and surface water sources.
What does over-cultivation of soil lead to?
Depletion of nutrients
Match the sustainable farming method with its benefit:
Crop Rotation ↔️ Restores soil nutrients
Organic Fertilization ↔️ Enhances soil fertility
Cover Crops ↔️ Protects soil from erosion
Conventional farming relies on synthetic fertilizers and
pesticides
Deforestation for agricultural land reduces biodiversity and
carbon sinks
.
What is the primary cause of water pollution in agriculture?
Fertilizers, pesticides, and animal waste
Pesticide runoff from agricultural fields contaminates water bodies, affecting aquatic
life
What are three benefits of crop rotation in sustainable agriculture?
Restores nutrients, improves soil structure, reduces pests
Organic fertilization enhances soil fertility with organic
matter
Water pollution from pesticides and fertilizers affects
aquatic
life.
Match the environmental impact with its description:
Water Pollution ↔️ Runoff contaminates water bodies
Soil Degradation ↔️ Disrupts soil biota and reduces fertility
Air Pollution ↔️ Fertilizer production releases greenhouse gases

fertilizers?
Integrated pest management
Sustainable agricultural practices aim to minimize environmental
impact
Steps in sustainable agricultural practices:
1️⃣ Crop Rotation
2️⃣ Organic Fertilizers
3️⃣ Integrated Pest Management (IPM)
4️⃣ Water Conservation
Sustainable practices enhance soil fertility and reduce
chemical
usage.
What type of farming contrasts with sustainable practices and leads to environmental degradation?
Conventional farming
Technology in sustainable agriculture improves efficiency, reduces waste, and promotes environmentally friendly
practices
Match the technology with its application in sustainable agriculture:
Precision Agriculture ↔️ Optimizes crop yields and reduces chemical use
Drones ↔️ Monitors crop health and detects issues early
Data Analytics ↔️ Informs farming decisions
Arrange the benefits of precision agriculture in sustainable farming:
1️⃣ Increased efficiency
2️⃣ Reduced waste
Drones in sustainable agriculture can detect crop issues
early
, reducing losses.
What benefit does data analytics provide to farmers in sustainable agriculture?
Improved productivity
Sustainable agriculture leverages technology to improve resource utilization and reduce environmental
degradation
What role does technology play in sustainable agriculture?
Improves efficiency and reduces waste
Precision agriculture uses data and GPS to optimize crop yields and reduce chemical
use
Drones
are used in agriculture to monitor crop health and detect issues early.
What does data analytics in agriculture help inform?
Farming decisions
Precision agriculture helps farmers apply fertilizers and pesticides only where
needed
Leveraging technology in agriculture reduces
environmental
degradation.
What is the main purpose of agricultural practices?
Maximize yield and productivity
Agricultural practices ensure a stable food
supply
What is one key benefit of agricultural practices?
Improved resource utilization
Agricultural practices contribute to maintaining
environmental sustainability
.
What does conventional farming rely on?
Synthetic fertilizers and pesticides
