The cotton stalk management study o f one-pass stalk embedding as a key component to a reduced tillage system and controlled traffic systems for cotton is in its fourth year of evaluation. The study was extended one extra year to verify yield results obtained in the 1998 crop year. The original hypothesis included reduced energy, improved soil condition, no disease differences, no nutrient differences and no yield differences. Of these hypothesis all are true except for yield differences. In years 1 and 2, no yield difference could be measured between stalk embedding and normal stalk disposal systems. However…
