A transform boundary is a fault zone where two plates slide past each other horizontally. Most transform faults are found in the ocean where they offset spreading ridges creating a zigzag pattern between the plates. Some transform faults occur on land.
The macronutrients include: The first threeâcarbon, hydrogen, and oxygenâare known as structural elements and are present in the atmosphere and growing environment. The next three are sometimes called the fertilizer elements since they are the familiar N-P-K identified on fertilizer labels.
Each is equally important to the plant, yet each is required in vastly different amounts. These differences have led to the grouping of these essential elements into three categories; primary (macro) nutrients, secondary nutrients, and micronutrients. PRIMARY (MACRO) NUTRIENTS.
