Which factors are important to know when considering which fertilizer analysis to choose
-
Electrical conductivity
-
Alkalinty
-
Concentrations of Ca and Mg
-
All of the above
Correct Answer
A. All of the aboveExplanation
When considering which fertilizer analysis to choose, it is important to know the electrical conductivity, alkalinity, and concentrations of Ca and Mg. Electrical conductivity is a measure of the soil's ability to conduct electrical current, which can indicate the nutrient availability. Alkalinity refers to the soil's pH level, which affects nutrient uptake by plants. Concentrations of Ca and Mg are essential for plant growth and can affect soil fertility. Therefore, considering all of these factors is important in determining the appropriate fertilizer analysis for optimal plant nutrition.Rate this question:

Electrical conductivity measures the precipitates in the solution.
-
True
-
False
Correct Answer
A. FalseExplanation
Electrical conductivity measures the ability of a substance to conduct electricity. It is not used to measure the precipitates in a solution. Precipitates are solid particles that form when two solutions react together. Therefore, the given statement is false.Rate this question:

Fertilizers react with the media or soil solution and produce acid, base or neutral reaction.
-
True
-
False
Correct Answer
A. TrueExplanation
Fertilizers can react with the media or soil solution and produce acid, base, or neutral reactions. This means that when fertilizers are applied to the soil, they can either increase the acidity, alkalinity, or maintain a neutral pH level. This is important because different plants have different pH requirements for optimal growth. Therefore, it is true that fertilizers can react with the media or soil solution and produce acid, base, or neutral reactions.Rate this question:

Water with low alkalinity has this characteristic
-
The CaCO3 level is > 300ppm
-
The media pH decreases over time
-
The media pH increases over time
-
Contains a high amount of impurities
Correct Answer
A. The media pH decreases over timeExplanation
Water with low alkalinity has the characteristic of the media pH decreasing over time. This means that the pH of the water becomes more acidic as time passes. This can be due to the lack of buffering capacity in the water, which prevents it from resisting changes in pH. As a result, the water becomes more susceptible to changes in acidity, causing the pH to gradually decrease.Rate this question:

Plantex Solutions 17-5-17 Complete has this attribute.
-
Must use the whole bag at one time when mixing up a concentrate drum
-
Is an alternative to rotating between 20-10-20 and a Cal Mag or injecting at the same time
-
Has a slightly acid potential acidity
-
All of the above
Correct Answer
A. All of the aboveExplanation
The correct answer is "All of the above". This means that Plantex Solutions 17-5-17 Complete has all the mentioned attributes. It must be used in its entirety when mixing up a concentrate drum, it can be used as an alternative to rotating between 20-10-20 and a Cal Mag or injecting at the same time, and it has a slightly acid potential acidity.Rate this question:

Optimum growth with very high alkaline water is achieved with acid injection
-
True
-
False
Correct Answer
A. TrueExplanation
The statement suggests that in order to achieve optimum growth with very high alkaline water, acid injection is required. This means that adding acid to the alkaline water helps create a more balanced pH level, which is beneficial for optimal growth. Therefore, the correct answer is True.Rate this question:

Fertilizer blends with Calcium Magnesium in them always have a basic potential reaction to media.
-
True
-
False
Correct Answer
A. FalseExplanation
Fertilizer blends with Calcium Magnesium in them do not always have a basic potential reaction to media. The reaction of a fertilizer blend depends on its specific composition and the presence of other elements. Calcium and magnesium can be found in both acidic and basic fertilizers, so it cannot be generalized that all blends containing them will have a basic potential reaction.Rate this question:
