	Nutrient change indicators
	RN2	SN1	SN2	RP2	SP1	LP1	RK1	RK2	SK2	LK1
r	0.946	−0.877	−0.679	0.932	−0.597	−0.791	0.455	0.795	−0.773	0.042

r, Pearson’s coefficients; p, p-values of the Pearson’s coefficients. The first letters of the nutrient change indicators R, S, and L represent the nutrient concentration in the root, stem, and leaves, respectively. The middle letters N, P, and K correspond to nitrogen, phosphorus, and potassium, respectively. The last two numbers (1 or 2) represent the nutrient change in either the first growth period or the second growth period, which is defined as from April to July and from August to December, respectively.
