Fields with such soils and landscape position with connectivity to surface waters may lose more than 0.5 kg P ha year−1 and often more than 1 kg P ha year−1.
Second, the abundance of fruit: oil palm plantations also produce more fruit (>10 Mg per ha year−1) than most tropical forests (<1 Mg fruit per ha year−1 on average)44,49,50.
This has encouraged vine growers in the Priorat region to create new plantations, increasing significantly the transformation rate from 7.5 ha year−1 between 1986 and 1998 to 36.1 ha year−1 in the 1998 2003 period.
According to Netto [4], the annual production of eucalyptus RFB in Continental Portugal is between 1.2 t (dm)/ha year (optimistic scenario) and 1.08 t (dm)/ha year (conservative scenario), i.e., on average 1.11 t (dm)/ha year.
This productivity used to be 23 m3/ha · year in 1990, and it should reach 42 m3/ha · year in 2025 [9].
The average productivity of Eucalyptus in Brazil reached 40 m3/ha · year in 2012 [2].
In 1990, the average productivity of eucalyptus in Brazil was 26 m3/ha · year.
The average productivity of Eucalyptus reached 40.7 m3/ha · year in 2012 [2].
In some regions of the country, the productivity of Eucalyptus spp. reached 100 m3/ha · year [3].
In some regions of the country, the average productivity of Eucalyptus reached 100 m3/ha · year [3].
