True or False: There are 20 chemical elements and only 10 of them are need for plant growth and development.
True
False
True or False: Hydrogen and Oxygen are supplied to the plant through carbon dioxide and water through photosynthesis process.
True
False
True or False: If there is a Potassium deficiency you will see speedy growth which causes plants to have spindly stalks and stems.
True
False
True or False: Nitrogen can be very immobile in the soil, this means we can have a significant loss through erosion.
True
False
True or False: Phosphorus is very immobile in the soil and moves with the soil, so erosion and plant removal is the main cause of low P in the soil.
True
False
True or False: Most of the deficiencies with Potassium (K) is found in clay soils as it is relatively immobile and leaching is the main cause of it leaving the soil.
True
False
True or False: Boron regulates the metabolism of carbohydrate in plants and deficiency occur in alkaline soils only.
True
False
True or False: Soils contain both acids and bases, the amounts of each are expresses by the pH.
True
False
True or False: The pH scale ranges from 0 to 14 with anything that falls on the scale at a 7.0 containing more acid than bases.
True
False
True or False: Magnesium is needed to activate growth enzymes in the plant and can easily be moved through the plant in the event of a deficiency to the new growth of the plant.
True
False
True or False: Copper, iron, chlorine and Boron show up in the soil as cations while molybdenum and manganese are in anion form.
True
False
True or False: A soil test measures the amount of pH of the plants and can help you determine the amount and type of fertilizer to use.
True
False
True or False: A soil test should represent the area around where lime and fertilizer should be added.
True
False
True or False: When using a soil tube make sure that you create a V-shaped cut into the soil to the proper depth and remove a 1 inch thick vertical slice from the smoothest side of the cut.
