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.

Plantex Solutions No Stretch, 15-0-20 is a fertilizer that can be used towards the end of the crop to help prolong shelf life and keep plants greener. This implies that using this fertilizer can have a positive effect on the plants, helping them stay fresh and green for a longer period of time. Therefore, the statement "True" is correct as it aligns with the information provided.

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.

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.

Plantex Solutions 19-2-19, Fertility Plus, has higher levels of Magnesium compared to Plantex 20-10-20. It also has higher levels of Manganese, zinc, and iron. Additionally, it has lower levels of Phosphorus. Therefore, the correct answer is "All of the above" as all the attributes mentioned in the options are true for Plantex Solutions 19-2-19, Fertility Plus.

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.

Knowing the potential acidity of a fertilizer is important when choosing an analysis because it helps determine the effect the fertilizer will have on the media pH. The potential acidity refers to the amount of acidity that can be released by the fertilizer when it is dissolved in water or in the growing media. By knowing this, growers can assess how the fertilizer will interact with the media and whether it will raise or lower the pH. This is crucial for maintaining optimal pH levels for plant growth and nutrient availability.

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.

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.

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.
