Risk of Leaching in Soils Amended by Compost and Digestate from Municipal Solid Waste

Table 3

First-order kinetic constant (kl) and P maximum leached estimated (P_max) for each biowaste and amended soil type.

BIOWASTE	Soil	kl 10^−3 (h^−1)	^∗Pmax (mg kg^−1)
Compost	A	1.7	108.0^Aa
	B	1.8	72.3^Ab
	C	1.7	99.5^Aa
Digestate	A	4.4	54.6^Ba
	B	6.2	47.8^Ba
	C	2.3	61.9^Ba

∗Same capital letters within a soil type indicate that there were no significant differences between the biowaste type at 𝛼=0.05. Same lowercase letters within the same biowaste type indicate that there were no significant differences between soil types.
