Natural, High-Calcium Gypsum Landplasters Ensure
Superior Productivity, Higher Profits for Peanut Growers


Natural, high-purity gypsum landplasters from the Industrial Products Division of United States Gypsum Company provide a superior combination of calcium content, solubility and application efficiencies for healthier, more productive peanut yields and higher profit margins for peanut growers.

The company's BEN FRANKLIN® 420 Landplaster, USG™ 500 Landplaster and Ben Franklin® Bagged Agricultural Gypsum deliver the highest levels of calcium in the industry, ensuring best-possible seed quality and germination. They are 150 times more soluble than limestone, enabling pods to easily absorb needed calcium while minimizing yield-reducing problems such as pops, rot and darkened plumules.

BEN FRANKLIN 420 Landplaster and USG 500 Landplaster are both manufactured in variable particle sizes, ranging from approximately 1/4" to dust. This ensures that peanut crops will receive consistent nutrition from initial pegging through maturity. The smaller particles are readily dissolved and absorbed by the pods, while the larger particles supply crops with calcium and sulfur in a "time release" fashion throughout the growing season.

Non-toxic and ecologically safe, these natural gypsum landplasters actually improve soil structure by minimizing surface crusting, and increasing water penetration and aeration. Due to their high calcium content and consistent spreadability, they cover more acreage and spread more evenly that other calcium sources.

"While the material cost for natural gypsum landplasters is higher than alternative calcium nutrients, that expense is more than made up for by savings in material usage and reductions in time, labor and fuel expenses," said Bill Babcock, product marketing manager with U.S. Gypusm Company.

BEN FRANKLIN 420 Landplaster is made from quarried anhydrite (CaSO4) and gypsum (CaSO4 2H2O). It delivers almost 20 percent more calcium than competing products and is sold in bulk from U.S. Gypsum's Norfolk, Va. plant.

USG 500 Landplaster delivers exceptionally high calcium and sulfur content. Its crystal surface and shape help improve flowability and contribute to faster calcium release. When stored outdoors the product's spreading characteristics are not adversely affected. Even when exposed directly to moisture, it does not "clump" and remains readily spreadable. It is available at Elizabeth River Terminals, Chesapeake, Va. and Marine Port Terminals, Brunswick, Ga.

Like 420 Landplaster, BEN FRANKLIN Bagged Agricultural Gypsum contains almost 20 percent more calcium than competing products. It is applied by a bander or drop spreader and is sold in 50-pound bags from U.S. Gypsum's Norfolk, Va. plant.
