In photosynthesis, the plant uses water and nutrients from the soil, and carbon dioxide from the air with the sunâs energy to create photosynthates. Oxygen is releases as a byproduct. Figure 2.thletes take up oxygen through their lungs. Plants take up oxygen through the stomata in their leaves and through their roots. Again, respiration is the burning of photosynthates for energy to grow and to do the internal âworkâ of living.
Seeding a New Lawn. The process of applying seed for a new lawn is the same for most applications, but preparation may be limited to raking and fertilizing. Prices for seeding new lawns across the country reflect variations in lot size and preparation requirements, but typically range from $400 to $800.
Determine the correct seeding rate for the type of grass you are planting. A pre-calculated rate will be in pounds per 1,000 square feet. Divide the number of pounds specified by 1,000 and multiply the new figure by the number of square feet in your planting area for the total amount of seed needed.. Measure out the total amount of grass seed required to cover the planting site and divide it into 2 equal portions. Calibrate the drop spreader to one-half the seeding rate. Pour one portion of grass seed into the drop spreader.
