Rosetta Stone is an ancient Egyptian stone discovered by a Frenchman called Bouchard in August 1799. The stone has inscriptions written in two languages (Egyptian and Greek) and in three writing systems (hieroglyphics, demotic script and the Greek alphabet). The inscriptions on the stone were written by a group of priests in Egypt to honour the Egyptian pharaoh. The inscription contains all the good things that the Egyptian pharaoh did for the priests and the people during his reign.

The practice of leaving crop residues on the field in between planting seasons is known as conservation tillage.
<h3>Conservation tillage</h3>
Some soils are prone to erosion once they are directly exposed to the impact of precipitation.
After harvesting crops from a field, the crop residues are left on the field to prevent the direct impact of precipitation in cause erosion. The crop residue, in addition, adds to the organic matter of the soil after their decomposition.
Such a practice is known as conservation tillage.
