Abstract
of the project Study pretreatment acid soil with calcium hydroxide from shell eggs
prepared for how to adjust the acidity of the soil, affecting agriculture and compare the fine acidity and acid soil with. soils containing calcium hydroxide. To fix the economy By the egg shells left over from the consumer to the benefits. The study done by a research one. Which is about calcium carbonate shell eggs. And research the chemistry of calcium carbonate (limestone) is changing. Sites calcium hydroxide (lime), where calcium carbonate is a treasure bass. And adjust the pH of acidic soils. By which we bring the egg shell calcium hydroxide extraction site by shell eggs were crushed, dried and then burned. Then mixed with water and then dried until it evaporates. Calcium hydroxide Sites After the trial by mixing with the soil pH to reduce the pH of the soil is suitable for agriculture.
