Use the tape measure to find the dimensions of the pitch. It is 22 yards long and 10 feet wide. Mark the edges of the measurements with stakes.
Pour the clay, sand, calcium carbonate, sodium and compost into the center of the marked field. Mix well with a shovel. Use a rake to spread it to the edges of the markers, with slightly more at the ends where wear occurs the most.
Water the clay and sand mixture until it's lightly damp. Use the turf roller to flatten out the new medium. Check your work with a level and rake extra material into thin areas. Roll the medium or "bulli" until it is hard and compact.
Pull a spiked roller across the surface of the pitch in both directions to make holes for the seed. Load a seeder and set it in the highest broadcast. Walk in even strips across the pitch to overseed the area. Lightly run a push broom over the area to knock the seed into the holes.
Set up a sprinkler and water for 15 minutes. Water daily in summer or every other day in spring. Fall and winter plantings are not ideal.
Fertilize the turf when it's 1 to 2 inches high. Apply 1/2 oz. of ammonium sulfate per 3 square feet of pitch. Mow the grass to a height of one-half inch. After establishment, water slowly and infrequently and allow the pitch to dry slightly between periods of irrigation.
