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.
the seeding rate varies depending on the cultivar or blend and is usually specified by the seed provider or on the bag of seed for example if you wish to plant a new kentucky bluegrass lawn the seeding rate is 2 to 3 pounds of seed per 1000 square feet if you are planting a tall fescue lawn the recommended rate is 8 to 10 pounds per 1000 square feet convert the seeding rate for the chosen grass cultivar or blend from pounds per 1000 square feet to pounds per acre if needed for example if the recommended seeding rate for a specific blend of grasses is 6 pounds per 1000 square feet multiply 6 by 43 56 to get 261 36 thus you would need just over 261 pounds of seed for 1 acre
