Study Notes

Wet Summer Crops

Wet summers are more suitable for crops such as Sorghum, sunflower, and cotton.

Dry Farming Advantages

Suitable for regions with low annual precipitation
Helps protect the soil from erosion
Retains soil moisture

Tree Planting Advantages

Reduces soil erosion due to strong root systems
Decreases surface water runoff
Reduces pollution
Increases soil biomass content
Absorbs carbon dioxide, contributing to reducing global warming
Provides oxygen essential for life
Creates natural habitats for wildlife

Bunds Advantages

Bunds reduce water runoff by channeling it along contour lines
They increase water infiltration and improve soil moisture
They significantly reduce soil erosion

Gullies Advantages

Deep ditches or channels that help reduce soil erosion by channeling rainwater
They can be used for irrigation and recharge groundwater

Windbreak Advantages

Protects soil from wind erosion
Contributes to water and air quality by protecting against airborne soil, chemical drifts, and dust
Provides food sources for wildlife
Improves agricultural landscape diversity
Increases irrigation efficiency, potentially leading to a 10% or more increase in crop yields in dry areas
Improves photosynthesis and water use efficiency due to microclimate changes in humidity and temperature
Generates additional income through saleable tree and shrub products like nuts and berries

Organic Fertilizers Advantages

Prevent soil erosion
Increase physical and biological nutrient storage mechanisms within the soil
Retain soil moisture
Eco-friendly and non-polluting
Lower cost compared to chemical fertilizers

Organic vs Chemical Fertilizers

Organic fertilizers are naturally derived from decaying plant and animal matter, contributing to soil health and not polluting water bodies.
Chemical fertilizers are synthesized from chemicals and can cause eutrophication, soil salinity, and groundwater contamination.

Soil Conservation Strategies

Land use management: Involves choosing suitable land for specific purposes, like crop land, pasture land, woodland, wildlife, and recreational land.
Vegetative and Mechanical practices: Include methods like strip cropping, tree planting/cropping, foliage crops, and land reforms.

Strip Cropping

Involves alternating strips of hay, wheat, or other forages with strips of row crops such as corn, soybeans, cotton, or sugar beets.

Tree Planting/ Tree Cropping

Replanting or regenerating forest areas previously damaged or destroyed
Creates instant forests

Foliage Crops (Cover Crops)

Small plants with thick ground foliage like alfalfa, groundnut, and barseem.
They cover the soil during non-cropping seasons or between plant rows.
Help prevent soil erosion and retain soil moisture.

Land Reforms

Redistribute land from the rich to the poor.
Includes regulations on land ownership, operation, leasing, sales, and inheritance.

Objectives of Land Reforms in India

Eliminate social inequality by removing exploitation.
Develop cooperative farming.
Create an efficient and productive agrarian economy through legislation.
Redistribute and reorganize land ownership and operational holdings for maximum land utilization.

Combating Deforestation Strategies

Reforestation: Replanting or regenerating forest areas previously damaged or destroyed.
Afforestation: Growing plants where forests haven't existed due to lack of trees or adverse factors.
Energy plantations: Growing specific tree and shrub species for fuel, harvested in shorter timeframes.
Forest harvesting of non-timber forest products: Harvesting plants, parts of plants, fungi, and other biological materials from forests for personal or commercial value.
Exploring alternative sources of livelihood: Focusing on eco-development plans like animal husbandry, diversified small-scale processing units, and energy generation.
Changing consumption patterns: Shifting towards organic and natural food to manage soil, increase productivity, and lessen the need for deforestation.

Van Mahotsava

A tree planting festival celebrated in India for a week, from 1st to 7th July, to raise awareness about forest conservation.
Started in 1950 by Dr. K.M. Munshi to encourage tree planting.

Eco Club or Green Club

Voluntary environment improvement groups
Aim to increase awareness about global environmental issues.

Energy Plantation

Growing specific species of trees and shrubs for fuel, harvested quickly.

Deforestation Facts

33 million acres of forests are cut down annually.
Timber harvesting in the tropics contributes 1.5 billion metric tons of carbon to the atmosphere, representing 20% of human-made greenhouse gas emissions.

Combating Deforestation Actions

Improved agricultural practices
Paper recycling
Forest management: Balancing wood removal with new tree growth
Purchasing sustainably harvested wood products

Reducing Deforestation Consumption

Buy used wood products.
Consume less wood products.
Purchase essential goods in bulk to reduce unnecessary packaging.

Managing Forest Grazing

Overgrazing: When plants are subjected to excessive grazing without sufficient recovery time.
Causes:
- Livestock numbers exceeding grazing land capacity.
- Grazing repeatedly over the same area.
- Lack of food driving livestock to consume all available grasses.
- Poverty preventing cattle owners from stall feeding.
- Lack of knowledge about overgrazing consequences.
Consequences:
- Reduces land's usefulness and productivity.
- Decreases biodiversity.
- Contributes to soil erosion and desertification.
- Potential for invasive species spreading.
- Loss of livestock due to fodder shortages.
Control:
- Practicing rotational grazing.
- Sustainable grassland management.
- Social fencing encouraging voluntary grazing restraint.
- Stall feeding.
- National Forest Policy, 1988, promoting controlled forest grazing.
