Chapter 35, Problem 2TYK
Summary Introduction
Introduction:
An algal bloom is a rapid accumulation in the algal population in fresh or marine water, and is identified by discoloration in water from their pigments. Blooms can affect animals or the ecology, and make cities to cut off water for residents. Algal blooms can block the sunlight for other organisms and can reduce the oxygen levels in water. Also, few algae produce poison in water.

Camellia and azalea are plants that produce yellow leaves, which is considered an undesirable outcome, when they are grown on alkaline soil. Which of the statements below support the fact about camellia and azalea stated above?
a. Loam soil is not advisable to be used in growing camellia and azalea because of its acidity.
b. Camellia and azalea should not be planted in chalk soil.
c. Camellia and azalea produced yellow leaves because they are planted in acidic soil.
d. Camellia and azalea require chalk soil to counter the effect of the alkaline soil used.
Fertile soil is one of the keys to good yield.
(i)
Explain the roles of clay and organic matter in contributing to soil fertility and cation
exchange capacity (CEC).
(ii)
Name ONE (1) negative effect of low CEC and high CEC soils respectively. Suggest
ways to improve low CEC and high CEC soils.
(iii)
Suggest ONE (1) suitable type of crops for high CEC soil, low CEC soil and loam soil
respectively.
Soil pH affects availability of nutrients for root absorption. The following statements are true except*
a. Low pH results in an increase in Aluminum toxicity.
b. Low pH results to unavailability of major nutrient elements.
c. Toxic metals are more available in acidic soil.
d. Low pH results in slow activity of soil-inhabiting microorganisms.

- It is June in Fresno and the officials at the water district have just reduced your irrigation ration by 26%. In the field, you determine that the water potential in your soil is -1.68 MPa while the water potential of your crop is -1.62 MPa. Question A. Is your crop able to take up water from the soil? Explain. Question B. It is now late August and your soil water potential is -2.10 MPa, fortunately, you have been granted one magic wish in altering the physiology of your crop to increase its ability to take up water, however, you must choose from one of the options below.

Planting pinto beans need many necessary factors, however, I think the type of soil is the most important one to grow it faster. Pinto beans are kind of plants can grow in dark and dry area, so even in dark (less light), they can grow as well. The goal is to determine that soils have different characteristics that can help or hurt plant growth. In order to discover the effects soils have on plant growth, three different soil samples will be used in a controlled study. The samples will vary in consistency, texture, color, location, moisture, and contact with human life to ensure that the samples are…arrow_forwardDiscuss the following prompt: In this experiment, we are looking to see how much different types of soil will affect the time it takes for pinto Bean seedlings to germinate out of the ground.
