Similarly, the production of lime from oyster shell is shown in the process flow diagram for the sake of completeness, even though use of this source of lime is declining. As a qualitative overview of the material flow of the entire industry, a chemical tree, Figure 1, has been included with the introductory section for the Lime Industry Processes.
Use 50 lbs Oyster Shell Lime per 1,000 square feet, depending on soil analysis and crop. Grower''s Tip: This allnatural soil amendment is produced by a living organism. Calcium formed in this noncrystalline state is more easily dissolved and utilized by the soil and plant.
