Unit 4 - Soil

Word

Example

soil

Soil is essential for plant growth as it provides nutrients

soil structure

Soil structure influences water retention and root growth

aeration

Aeration helps roots breathe and prevents waterlogging

soil texture

The soil texture affects how easily plants can absorb water

sandy

Sandy soil drains water quickly but doesn't hold nutrients well

silt

Silt soil is fertile but prone to erosion

clay

Clay soil retains water and nutrients but can become compacted

loam

Loam is the ideal soil for most plants, with balanced nutrients

humus

Humus improves soil fertility and water retention

parent material

Parent material is the rock from which soil forms

dense

Dense soil can make it difficult for roots to penetrate

pH

Soil pH affects nutrient availability for plants

fertility

Soil fertility is crucial for producing healthy crops

drainage

Proper drainage prevents water from accumulating around plant roots

erosion

Erosion is the loss of soil due to wind or water

mulch

Mulch helps retain moisture in the soil and suppresses weeds

compost

Compost is made from decomposed organic materials

fertilizer

Fertilizer adds essential nutrients to the soil for plant growth

irrigation

Irrigation systems provide water to crops in dry areas

tillage

Tillage involves turning over the soil to prepare for planting

crop rotation

Crop rotation helps prevent soil depletion and pest build-up

organic matter

Organic matter enriches the soil and promotes microbial activity

microorganisms

Microorganisms in soil break down organic material and release nutrients

soil erosion

Soil erosion can lead to the loss of fertile land

runoff

Runoff carries soil away from fields after heavy rainfall

water retention

Clay soil has excellent water retention properties

soil management

Soil management techniques help improve soil health and productivity

soil amendment

Soil amendments such as lime or sulfur can adjust pH levels

heavy metals

Heavy metals in soil can harm plant growth and animal health

contamination

Soil contamination occurs when harmful chemicals enter the soil

soil test

A soil test can determine the nutrient needs of the soil

soil ph

A soil pH test is important for determining the right fertilizer

salinity

High salinity in soil can affect plant growth

soil pollution

Soil pollution is a growing concern in urban areas
