Soil Types
This soil texture is made of large, coarse particles that feel rough or gritty.
sand
Bringing water to the crops using pipes, canals, and sprinklers
Irrigation
Breeding and harvesting aquatic organisms for human consumption or sale.
Aquaculture
The ability of water to pass through the pores of rocks and soil
permeability
Crops are
plants
This soil texture is made of tiny (small) or fine particles. It is smooth and hard when dry but sticky when wet.
clay
Practice of growing MANY crops at the same time for harvest
poly-cropping
Living organisms whose genes have been altered
Genetically Modified Organisms (GMOs)
What soil particles have a HIGHER porosity and permeability?
sand particles
the amount of a crop produced on an area of land
crop yield
This soil texture is made of medium-sized particles. It feels smooth when dry but slippery when wet.
silt
Practice of planting ONE of the same crop, year after year on the same area of land
monocropping
A chemical used to reduce and kill the pest population
pesticide
The amount of empty space between soil and rock particles
porosity
What types of countries consume more livestock (meat products)?
Developed countries (affluent or rich)
The most important property of soil is the
texture
A simple method of farming that USES ANIMALS to help produce and sell small numbers of food for families
traditional (subsistence) farming
Aquaculture is negatively affected due to runoff from chemicals like
fertilizers and pesticides
What soil particles have a LOWER porosity and permeability?
clay particles
How do modern machinery, irrigation, and chemicals affect soil quality?
They degrade/destroy the soil quality.
The layer of the earth where plants grow
soil
An advanced farming technique that uses genetic engineering, technology, and pesticides to produce many crops for populations.
Modern (industrial) farming
The Green Revolution caused an ___________________ in the amount of crop yields, chemicals, and machines.
Increase
According to the soil texture triangle, a soil's texture is determined by
the percentage of the soil type
Why do crops in tropical climates suffer more than ones in temperate climates?
Pests can grow and reproduce faster in tropical climates
