Four Agricultural Inventions

Certainly! Here are four significant agricultural inventions: 1. **Mechanical Tractor**: Replaces manual labor by pulling plows and harvesters, greatly increasing farming efficiency and productivity. 2. **Chemical Fertilizers**: Provide essential nutrients to crops, helping plants grow faster and yield more food. 3. **Crop Rotation**: A farming technique where different crops are planted in the same soil across seasons, improving soil health and reducing pests. 4. **Combine Harvester**: A machine that combines reaping, threshing, and winnowing, enabling quick and large-scale harvesting of crops like wheat and barley. These inventions transformed agriculture by boosting productivity and sustainability.
