This question  was well attempted by the candidates.  In 1(a)(i-ii), majority of the candidates were able to identify specimens A(Clayey soil) and  B(Sandy soil)  though only a few of them were able to name the crops that would thrive well on specimens A(Clayey soil) and B(Sandy soil).  More so, most of the candidates were able to mention the ways by which specimen B(Sandy soil) can be improved as required in 1a(iii).
Further to this, most of the candidates were able to identify specimens C(Millipede)  and D (Cow dung), state the ways in which specimen C(Millipede)is important in crop production as well as state the uses of specimen D (Cow dung) in agriculture as required in 1(b)(i-iii).
