Environment Evaluation and Selection for Crop Production (Part 2) Flashcards
1
Q
GOOD LOCATION FOR CROP PRODUCTION
A
- access to adequate infrastructure
- favorable socio-economic conditions
2
Q
ACCESS TO INFRASTRUCTURES (LOCATION)
A
- farm to market roads
- electricity and water resources
- port facilities
- communication facilities
- post-harvest facilities
3
Q
SOCIO-ECONOMIC CONDITIONS (LOCATION)
A
- peace and order
- political stability
- availability and cost of manpower
- government policies
4
Q
SUITABLE SITE
A
- factors that directly affect crop growth
- SOIL and CLIMATE
5
Q
FUNCTIONS OF SOIL
A
- medium for plant growth
- habitat for soil organisms
- water supply
- recycling nutrients
- engineering medium
6
Q
SOIL CHARACTERISTICS THAT AFFECT CROP PRODUCTION
A
- soil depth
- soil texture
- soil structure
- nutrient/OM content
- soil pH
7
Q
SOIL DEPTH
A
- determined by digging a pit
- measure of thickness of topsoil from soil surface to hardpan layer
8
Q
TOPSOIL
A
- most fertile layer of soil
9
Q
SOIL DEPTH FOR PERENNIAL CROPS
A
- at least 80cm deep
- roots should be able to explore and obtain water and nutrients
- essential for typhoon-prone area
10
Q
SOIL DEPTH FOR ANNUAL CROPS
A
- shallower soil
11
Q
SOIL TEXTURE
A
- relative proportion of soil particles (sand, silt, clay)
- affects soil characteristics (WHC, CEC, drainage)
12
Q
SOIL TEXTURE IDEAL FOR MOST CROPS
A
LOAMY SOIL (moderate soil texture)
13
Q
SOIL STRUCTURE
A
- arrangement and clustering of soil particles
- determined by kind and amounts of cementing materials
- determined by soil management
14
Q
CLASSIFICATION OF SOIL STRUCTURE
A
- granular
- blocky
- prismatic
- columnar
- platy
- single grained
15
Q
SOIL STRUCTURE IDEAL FOR CROP PRODUCTION
A
- granular and porous for easy root proliferation
