Fig. 2. Fiber length (L) and micronaire (M) of cotton as a function of total plant-available N applied as broiler litter and urea–ammonium nitrate solution for 3 yr under CT (Cruger, MS) and NT (Coffeeville, MS) systems. Applied plant-available N was estimated as a sum of 100% UAN–N and 50% of litter-N. Fitted lines are best-fit curves.
