Soil solarization. Follow these four steps to solarize your soil: cultivate and remove plant matter; level and smooth the soil; irrigate; and lay a clear tarp on the soil surface for 4 to 8 weeks, depending on local conditions.
Die casting is a manufacturing process that can produce geometrically complex metal parts through the use of reusable molds, called dies. The die casting process involves the use of a furnace, metal, die casting machine, and die. The metal, typically a non-ferrous alloy such as aluminum or zinc, is melted in the furnace and then injected into the dies in the die casting machine.
Cast iron and cast steel are two types of iron-carbon alloys. The main difference between these alloys is the carbon content in the composition. Cast iron is rich in carbon more than cast steel. Cast iron contains over 2% of carbon and cast steel contains less than 2% of carbon in weight. The purpose of this casting with carbon is to alter the properties of iron for advanced applications. Because, iron itself alone is a soft metal and it is not ideal for construction materials.
