Statistics included in this report are value of farms, land, value of sales, amount of crop harvested, production, and inventory.
The amount of crop harvested varies with land quality, among other factors, and yields range between 21 and 27 oven dried tonnes per hectare (odt/ha) [9].
Dividing the farmland into a grid, the students started by noting the amount of harvest Mitchell collected from each grid square.
The primary goals of Songgye were to determine the annual amount of harvest and assign certain areas for specific uses and activities.
Two treatments were replicated in two blocks after clear-cutting 7-year-old stands: in treatment R, all the litter above the mineral soil was removed before planting, and in a double slash (DS) treatment, the amount of harvest residues was doubled.
Overall, the total amount of harvest provided by AR is negligible, equal to about 6.3 Mm3 in 2012, i.e., about 1.2%% of the total amount of harvest obtained from FM at the EU level.
For Portugal, the amount of harvest provided by afforestation (AR) is also reported (panel a, left panel).
This parameter provides a link between the broadly defined forest management practice (e.g. through ranges) and the amount of harvest that actually occurred during the RP.
These differences may be due to the relative amount of harvest provided by Eucalyptus plantations accounted as AR (from less than 15%% of the total amount of harvest in 2002 to about 25%% in 2011, as highlighted in the harvest's panel of Fig. 6, panels A).
After 2008, due to different assumptions about the average amount of harvest and about the effect of natural disturbances (country's data report a constant amount of harvest equal to about 25 million m3 from 2009 to 2012) our estimates are not comparable with the country because we used different harvest rates.
