Application and source describe the ways that fertilizers have changed in the last 100 years. One hundred years ago, in 1918, fertilizers tended to be humus-, kitchen scrap-, leaf litter- or manure-based for application in-place or as part of plowing and weeding. One hundred years later, in 2018, fertilizers will be found in artificial, chemical, genetically engineered or synthetic and in organic forms and with granular, liquid or particle treatments.
Fertilizers have become more specialized and efficient in the last 100 years with the development of synthetic fertilizers, precision agriculture techniques, and slow-release formulas. These advancements have helped to increase crop yields, reduce environmental impact, and improve nutrient management in agriculture.
The world's current tin reserves are estimated to last for around 100 years at current production rates. However, new reserves may be discovered, and technologies for recycling and more efficient use of tin could extend this timeframe.
If the substance has a half-life of 10 years, there would be 10 half-lives in a 100-year span. Each half-life reduces the amount by half, so after 100 years, 1/2^10 = 1/1024 grams of the sample would remain.
The half-life of carbon-14 is about 5700 years. This means that in 5700 years, half of the original 200 grams (100 grams) will have decayed. To decay from 200 grams to 100 grams, it will take one half-life, or 5700 years.
Metals commonly used 100 years ago included iron, steel, copper, and aluminum. These metals were widely utilized in construction, transportation, and manufacturing industries during that time period.
