Research conducted by Dr. Vincent Haby revealed fine limestone (ECCE 100%) increased cost efficiency, forage production efficiency, and duration of soil pH change compared to coarse limestone (ECCE 62%).  One ton of fine limestone increases pH to the same extent as caused by 1.61 tons of coarse limestone.   In many East Texas areas, significant cost savings will be realized from using fine limestone for equivalent effectiveness. More information on fine lime and liming soils may be found in the following research reports: 1) Effective Calcium Carbonate Equivalence (ECCE) of… Read More →
