Instructions for Composing Technology 10 Lesson 7 Shortest
Question page 23 Technology 10
Give some practical examples of the soil solution reaction.
Answer
The soil solution reaction is only acidic, alkaline and neutral of the soil. Based on this property, we have measures to improve the soil, choose the most suitable plants for the soil such as liming, organic fertilizers, and reasonable chemical fertilizers to reduce acidity. Physiological sour fertilizer (SMALL)4)2SO4KY2SO4gypsum reduces alkali.
Question page 24 Technology 10
From the concept of soil fertility, what factors determine the fertility of the soil? To increase the fertility of the soil, what technical measures must be applied?
Answer
Factors that affect soil fertility are:
Country.
+ Nutrients.
+ Does not contain substances harmful to plants.
To increase soil fertility, we often apply the following technical measures:
+ Fertilize (Green manure or manure).
Keep water in the soil by planting cover crops.
Question page 24 Technology 10
Give some examples of the positive influence of production on the formation of soil fertility.
Answer
For example, before the harvest, we will plow, make the soil loose, water to ensure moisture, then harrow again, or can fertilize with phosphate fertilizer to increase the fertility of the soil.
Compose Lesson 1, page 24 in the shortest time:
What is soil glue? Describe the structure of soil glue.
Answer
– Particles less than 1 micrometer in size, in suspension in water, insoluble in water are called colloids.
– Structure of earth glue:
+ Acacia has one core.
The layer of ions that determine electricity is located just outside the nucleus.
+ The two outermost layers are the immobilized ion layer and the diffuse ion carries the opposite charge to the determining ion.
Compose the shortest Lesson 2, page 24:
What is the adsorption capacity of the soil?
Answer
The adsorption capacity of the soil is the ability to hold nutrients, limon particles, and clay particles that are less easily washed away and eroded under the influence of external factors such as rain water and irrigation water.
Compose the shortest Lesson 3, page 24:
What is the soil solution reaction? Give some practical examples of soil solution reactions.
Answer
– Acidity, alkalinity, neutrality of the soil (measured by pH) is called the soil solution reaction.
– Example of practical significance of soil solution reaction: Based on the properties of the soil, we have measures to improve the soil, choose the most suitable plants for the soil such as liming, organic fertilizers, and chemical fertilizers. Reasonable study reduces acidity. Physiological sour fertilizer (SMALL)4)2SO4KY2SO4gypsum reduces alkali
Prepare the shortest Lesson 4, page 24:
What is soil fertility? List some technical measures to increase soil fertility.
Answer
– The ability to continuously and simultaneously supply water, nutrients (and not contain harmful substances) to plants is called soil fertility.
Some technical measures to increase soil fertility are:
+ Fertilizing (green manure for legumes, manure, …).
+ Keep water in the soil by planting cover crops.
+ Land preparation and drying are expensive to reduce pathogens.
