Effect of Thinning and Harvest Type on Storage and Losses of Phosphorous in Pinus taeda L. Plantations in Subtropical Argentina

Table 1

Content of P (kg·ha⁻¹) and ecosystem total percentage (between brackets) according to thinning intensity.

Compartment	Treatment (% thinned)
	0%	33%	66%
Tree layer	40.1 (70.6)^a	31.6 (67.4)^b	21.2 (54.9)^c
Shrub layer	0.17 (0.3)^b	0.87 (1.9)^b	4.55 (11.8)^a
Herbaceous layer	1.69 (3.0)^a	1.70 (3.6)^a	1.73 (4.5)^a
Forest floor	8.00 (14.1)^a	5.79 (12.4)^a	5.42 (14.0)^a
Soil	6.84 (12.0)^a	6.89 (14.7)^a	5.73 (14.8)^a
Total	56.80 (100)^a	46.85 (100)^b	38.63 (100)^b

Different letters indicate significant statistical differences (𝑃<.05) among treatments.
