Franchising Fertilizers from recycle eggshells and soil from swamps
Soil from Swamps can be Used as Fertilizers
One ton (1,000 kilos) of dry peat -- a mixture of soil and organic matter found mostly in swampy areas -- can supply as much as 40 kilos each of the major plant foods, or equivalent to two bags of ammonium sulfate (21-0-0 NPK). Peat is black in color and weighs relatively light.
Recycle Eggshells as Fertilizers
Eggshells can be used as fertilizers, cement and tile binder and paste ingredient after grinding them finely. They contain calcium, phosphorus, potassium and sulfur which makes plants robust and vigorous. Ground eggshells can also be used as a reinforcing ingredient in pastes. Mixed with starch, the sticky substance can bind paper effectively. When used as a cement binder, the mixture dries easily and as tile binder, it gives a hard but smooth finish. One part white cement is mixed with every two parts ground shell.
