the one 指一种土壤,什么土壤呢?后面有限定语for which it has been specially developed,这里的which是引导修饰the one 的从句,所以which = the one = one certain kind of soil.it指前面的crop.
全句的意思是,这种庄稼在大部分土壤里长势不好,除了一种土壤,这种庄稼是专为这种土壤特化的. 如还有不解请追问.

the one指另一种农作物，用which作定语，修饰这个另一种农作物，后面说了it has been specially developed，特别发展出的农作物，it就跟the one是一个东西，都说的另一种农作物。

the one 代指的是一种可以种植这种作物的东西，which引导的定语从句，先行词是the one，it 指代的是this crop。
