Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
38 words
A method of fertilizing plants which comprises the application of a polyborate compound which comprises the reaction product of a boric acid compound with at least one amine selected from the group consisting of alkanolamines and aliphatic polyamines.
Claim 2
Independent Claim
38 words
A method of fertilizing plants which comprises the application of a polyborate compound which comprises the reaction product of a boric acid compound with at least one amine selected from the group consisting of alkanolamines and aliphatic polyamines.
Claim 3
Dependent Claim
11 words
