Soil Composition
These are the four main components of soil.
What are mineral particles, organic content, gases, and water?
This soil type drains best due to large pore spaces.
What is sandy soil?
These are the three major nutrients needed by plants.
What are nitrogen, phosphorus, and potassium?
This green pigment is essential for photosynthesis.
What is chlorophyll?
This crop can tolerate frost and prefers cooler temperatures.
What is wheat?
This term describes material derived from living organisms.
What is organic?
This soil type retains the most water due to small particle size.
What is clay soil?
This is the ion form in which nitrogen is absorbed.
What is nitrate (NO₃⁻)?
These are the two main reactants in photosynthesis.
What are carbon dioxide and water?
This crop requires the most water to produce 1 kg.
What is rice?
These organisms help break down organic matter and improve soil structure.
What are decomposers?
This is how organic matter improves soil aeration.
What is by increasing air spaces?
This is the effect of soil pH on nutrient availability.
What is it affects how easily nutrients are absorbed by plant roots?
This is how temperature affects photosynthesis.
What is higher temperatures increase reaction speed?
This crop grows best in sandy to loam soil and warmer temperatures.
What is maize?
This is the name for partially decomposed organic matter that retains nutrients.
What is humus?
This is how particle size affects ease of cultivation.
What is larger particles make soil easier to cultivate?
This is the ideal pH range for sweet potato growth.
What is pH 5.0–5.5?
This is why wilting leaves reduce photosynthesis.
What is they are not positioned to collect sunlight efficiently?
This crop would be damaged by ice and snow.
What is banana?
This soil type combines sand, silt, and clay for ideal growing conditions.
What is loam?
This is how farmers can improve soil structure and fertility.
What is by adding organic matter?
This is the definition of nutrient deficiency.
What is a shortage of essential mineral ions for healthy growth?
This is how wind affects water availability in soil.
What is it increases evaporation and transpiration?
This is why farmers use local knowledge when selecting crops.
What is to choose varieties best suited to local weather conditions?
