Consider the following statements regarding limiting nutrients. Select True or False for each statement. T/F Nitrogen (N), phosphorus (P), and potassium (K) are common examples. T/F Their presence limits the availability of micronutrients. T/F Their availability tends to limit plant growth. T/F Certain macronutrients and micronutrients can be considered limiting nutrients.

Question

Accepted Answer

Hi everyone. Here's our next problem. It says identify the incorrect statement about limiting nutrients. Well uh as it's pretty easy to recall from looking at the name limiting nutrients limiting nutrients are those nutrients without which a plant cannot continue to grow. So let's look through our answer choices, remembering that we are looking for the false or incorrect statement here. Choice A says the unavailability, unavailability of these nutrients restricts plant growth. Well that is true and therefore not our answer. That's what limiting nutrient means. If the plant doesn't have it, its growth is restricted. Choice B says the most limiting nutrients for plant growth are considered to be nitrogen, phosphorus and potassium. Well this is also true. Um These are macronutrients meaning they're needed in large amounts relatively speaking for a plant to grow. So that is not our correct answer. Since it's a true statement toi C says only a few macronutrients are considering considered limiting nutrients. Well this is false. While macronutrients are things that are needed in relatively large amounts, um They're not the only limiting nutrients. There are micro nutrients that although they're only needed in small amounts, they are necessary for plant growth. Um Some of those include boron, chlorine, manganese, iron and some others. So this will be our answer as that's an incorrect statement due to that only. And finally, choice D if the limiting nutrients are added in appropriate quantities to the soil as fertilizer plant growth usually increases And this is true. Obviously if the plant has run out of them and you add them as fertilizer, your plant then has what it needs and can continue to grow. So Choice D. Is not a correct answer. So the incorrect statement about limiting nutrients is choice. See only a few macronutrients are considered limiting nutrients. We'll see you in the next video.
