Farmers planting spring crops will usually wait for soil temperatures to stabilize above approximately 14C before planting, thus avoiding the loss of their crop because of low temperatures. For Greek cotton farmers earlier emergence is desirable because cotton will mature before the rainy season. Even a weeks difference in planting time may be the difference between success and failure for the crop year. For this reason, a 3-year study was undertaken to investigate the variation in the seedbed temperature of plots prepared with five different tillage techniques, namely, a) conventional tillage, b) reduced tillage with heavy cultivator, c) reduced tillage with rotary cultivator, d) reduced tillage with disk harrow, e) zero tillage. Soil temperature was measured at the soil surface, at 4cm and 8cm. Conventional tillage and heavy cultivator techniques presented the highest temperature range. Soil at 4cm had a temperature range 2-4 C higher in relation with the soil at 8cm.(Download PDF) (Export to EndNotes)
