Document Summary

Crops (such as maize, soy, barley, tomatoes, sorghum, peaches, apples, peas, etc. ) Bushel of each product now has a standardized weight equivalent in usa. We can use these typical numbers to compared yield in different places under different circumstances. After converting faostat data for yield from hg/ha to t/ha. 1 joule (j) = energy required to raise the temp of 1 cm3 of water 1 degree c. 1 food calorie* = 1 cal or 1 kcal = 4180 j. *note: the word calorie actually means 1/1000 of a kcal. 25 bu/ac of corn = how many t/ha. 1 acre = . 4 hectare or 2. 5 acres = 1hectare. 25 bu x 25. 4 = 25. 4 635 kg. 635 / . 4 = 1. 5875 t/ha (that"s a really poor yield) 140 bu/ac is a good yield of corn. 1 acre = . 4; 1 ha = 2. 4 acres. Convert bu/ac to t/ac - first to kg then to t.
