Lesson 08: Feeding the Grass
Yellow can be a very attractive color, especially in the autumn when the leaves turn and tree-covered landscapes are painted in warm colors. But when yellow becomes infused with the green of growing grass, it usually indicates that something is wrong. Chlorotic leaves may be diseased, injured, or deficient in nitrogen, oxygen or some element essential to their healthy, vigorous growth.
Obviously, there is something wrong with the chlorotic turfgrass leaves appearing through your magnifying glass. The new superintendent, who is also on his hands and knees, asks: "Have you ever seen anything like this?" While he's only been at this course for a few months, he has already tried a long list of the things to remedy the situation, none of which have worked. Soluble nitrogen, along with some potassium sulfate, not only did not help, it appeared to make the situation worse. In response to your suggestion that he have plant-tissue and soil samples tested, he responded: "Do you really think that's necessary?"
As you reflect on this experience, consider the following questions:
What to do...
In this lesson you will review information on Fertilization and Nutrition. Throughout this lesson you will be prompted to do self-checks. If are able to answer all the questions in the self check correctly, you will have the option to skip over some of the material presented in this lesson, of course you can review everything if you want.
When you are finished going through the lesson, access the Lesson 08 Quiz. You can take the quiz up to 5 times. Practice! The questions are just like those you will find on the exams.
