Using a plastic mulch would increase soil temperatures in the spring by trapping heat from the sun and preventing it from escaping the soil. This would create a warmer microclimate for seeds and plants to grow in. Applying organic residues, following no-till practices, irrigating the soil, and using the moldboard plow may have other benefits for soil health, but they would not necessarily increase soil temperatures in the spring.
