A Three-Year Study on the Effects of Lime Applications on the Standing Crop of Benthic Organisms in Georgia Farm Ponds

Six Georgia farm ponds, three on sandy soils and three on clay soils, were observed during a 32-month study period to determine the quantitative production of benthic organisms in relation to applications of agricultural lime. Three of the ponds were treated with lime at the rate of one ton per acre. The remaining three ponds were maintained as controls. Water total hardness in the experimental ponds increased significantly during the first year after treatment and began to drop during the third year, although it remained at a level higher than that observed before treatment. The bottom...
