pH of fertilizer, soil, foliar, and blueberry fruit samples in 2017–2018.

Fertilizer treatment	Fertilizer	Soil	Foliar	Fruit
CON	/	4.69 ± 0.07	6.05 ± 0.01	3.51 ± 0.03
AS1	1.77 ± 0.00	4.65 ± 0.12
AS2	1.77 ± 0.00	4.75 ± 0.10

Data are represented as mean ± SEM, n = 12, 6 and 32 for fertilizer, foliar or fruit and soil, respectively. The pH of soil was averaged from pH of soil samples collected at March (pre-fertilizer application), April (post-fertilizer application), June and August of each production season, four samples per sampling points, thus a total of 32 samples. /, not measured; CON, standard fertilization; AS1, manure-derived ammonium sulfate; AS2, manure-derived ammonium sulfate applied in split applications.
