Table 1 Ionomic analysis of soybean trifoliate leaves (cv. BRS 1010 IPRO) in response to K + soil fertilization.

Treatments		Leaf DW	P	K +	Ca2+	Mg2+	S	Zn2+	Mn2+	Fe2+	Cu2+	B
Leaf DW – leaf dry weight; KVL – very low K + availability; KL – low K + availability; KM – medium K + availability; KVH – very high K + availability; LT – lower third; MT – medium third; UT– upper third; The data presented are representations of the mean (n = 6) and results of ANOVA + Tukey’ s test (p ≤ 0.05); Different lower case letters indicate differences amongst K + availability conditions (KVL, KL, KM, and KVH) in the same soybean tissue; Different capital letters indicate differences amongst soybean trifoliate leaves (LT, MT, and UT) in the same K + treatment.
