Technical Abstract: Soil carbon sequestration is difficult in Texas, in part, because of the high annual temperatures and low rainfall amounts in portions of the state. However, research has shown that carbon can be sequestered with a variety of management systems. These systems include: i. Continuous cropping in areas which have been historically fallowed for large periods of time; ii. Conversion to reduced or no-till management systems; and, iii. The establishment of long-term grasslands. The rate of carbon sequestration with the suggested management systems has been shown to vary with climatic conditions, primarily rainfall amount and annual temperature.
