Cotton Plant Climate Requirements
Cotton is a plant that needs a long frost-free period, a lot of heat and plenty of sunshine. It prefers warm and humid climate. Cotton seeds will have a small germination rate, if the soil temperature is below 60°F (15°C). During active growth, the ideal air temperature is 70 to 100°F (21-37°C). Temperatures well above 100°F are not desirable. However, the average cotton plant can survive in temperatures up to 110°F (43°C) for short periods without great damage, but this also depends on the humidity levels. In order to cultivate cotton plants successfully, we shall not have excessive rainfalls during the maturing (summer) and during the days of harvest (during autumn).
Cotton Plant Soil Requirements and Preparation
Cotton can grow in almost all well drained soils. However, suitable soils for achieving high yields are considered the deep well drained sandy loam soils, with enough clay, organic matter and a moderate concentration of nitrogen and phosphorus. The best yields are often achieved in loamy soils that are rich in calcium carbonate. A gentle slope generally helps the water drainage and is sometimes desired.
We start the preparation of the field during autumn (after harvesting), by making a good plowing, approximately at a depth of 14 inches (35 cm). In that way, we incorporate the remaining plants into the soil, something that improves soil texture. In late winter (depending on the region), we check for weeds and plow again the field, so as to make our soil suitable and ready to welcome our cotton seeds.
