Less litter can be expected however,the soil remains stable and can <br /> become very resistant to change depending on the degree to which the inland saltgrass has increased in the community. <br /> Total annual production,during an average year,ranges from 700 to 1900 pounds per acre air-dry weight and will average 1300 pounds. <br /> Plant Growth Curve <br /> Growth curve number: C06909 <br /> Growth Curve name: Warm season dominant,cool season sub-dominant;MLRA-69;lowland water influenced soils <br /> Growth curve description: <br /> Percent Production by Month <br /> Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec <br /> 0 0 3 7 15 35 25 10 3 2 0 0 <br /> https://esis.sc.egov.usda.gov/ESDReport/fsReportPrt.aspx?id=R069XY03000&rptLevel=all&approved=yes&repType=regular&scrns=&comm= 7/15 <br />
