It contains data on herbicide use in US corn and soybean extracted from a systematic review of literature. The code allows to construct a crop-country-year dataset on herbicide use and compare it to a public benchmark dataset.United StatesData extracted from literature on herbicide use in US corn and soybeanThe benchmark data used for comparison in the analysis is: U.S. Department of Agriculture, National Agricultural Statistics Service.
