Engine start & taxi were normal, however while back taxiing on runway 29, I pulled the Carb. Heat & the engine noticeably ran better. Mag check and run up were normal, minimal differential when carb. heat checked...On take off carb. heat was placed on. The ground run was acceptable & a positive rate of climb was established. At 300 feet +/-, I pushed in the Carb. heat. With no change in engine sound the aircraft began to sink soon after. Prior to touchdown I pulled the power off to minimize engine damage. Landing in a cornfield a few hundred yards from the runway followed...Touch down was on the main landing gear followed by a nose over as the nose wheel dug into the soft dirt."
