TABLE 1.

Biomass, production, turnover rate, and lifespan of fine roots in the years 2005 and 2016 of the Scots pine forest under dry and irrigated conditions.

Fine-root traits	Year 2005			Year 2016
	Dry	Irrigated	P	Dry	Irrigated	P
Biomass (g m–2)	87.2	105.3	0.55	111.5	198.5	0.01
Production (g m–2 y–1)	54.9	53.2	0.89	33.8	66.1	0.02
Turnover (y–1)	0.73	0.61	–	0.30	0.33	–
Lifespan (year)	1.38	1.64	–	3.31	3.00	–

Biomass corresponds to standing biomass estimated by soil coring, production corresponds to annual production estimated by ingrowth cores, turnover corresponds to turnover rate (calculated as production divided by biomass), lifespan corresponds to root age and is the inverse of turnover. Turnover and lifespan were calculated per treatment. One-way ANOVA; significant effects (P < 0.05) are shown in bold.
