Extracted text: A farmer grows sugarcane in a sandy soil which is subjected to disposal of salt brines in southern Louisiana. What is the max allowance of salt brine should you recommend to the farmer in terms of kg/acre or lb/acre? (Assuming sugarcane can tolerate about 7 dS/m based on saturated paste extraction and the sandy soil can saturate 25 g water per 100 g soil). Also, 1 acre of surface soil (6") is about 1,000,000 kg or 2,000,000lbs.
