Fertilizers and pesticides are useful tools in farming and agriculture. They have been employed by farmers since as early as 2500 BC. Some old forms of fertilizer, like cow manure, are still being used today.
Uses of Fertilizer and Pesticides
Fertilizers and pesticides are used to promote healthy plant growth. Both fertilizers and pesticides have been employed by farmers for almost as long as people have been farming.
Who Discovered Fertilizer?
Fertilizer has been around as long as people and animals have been around. In its earliest form, fertilizer was made from animal manure. People simply took the manure from their farm animals and spread it on their crops. In modern days, people use fertilizers that contain nutrients that are essential for the growth of plants, like nitrogen.
Justus von Liebig
Justus von Liebig can be credited with creating some of the first chemical fertilizers, along with his research partner Friedrich Wohler. These men came up with the prototypes for nitrogen-based fertilizers. Many of the theories Liebig and Wohler worked on are still applied in modern-day fertilizers.
Who Discovered Pesticides?
Pesticides, like fertilizers, have been around for a long time. One of the first documented uses of pesticides was in 2500 BC, when people would dust their plants with sulfur to get rid of the insects in their crops.
Problems with Pesticides
Pesticides can contain chemicals that can be harmful to some plants. When used too much, pesticides can even kill plants. Some producers are working with pesticides that contain natural ingredients that are less harmful to the plants. Pesticides also come with instructions concerning how often they should be used, which, when heeded, can help minimize the damage to plants.
