Are chemical fertilizers appropriate for limited-resource farmers?
We dealt with this issue in detail at the start of Chapter 8 where the overall advantages of organic fertilizers were stressed. It was recommended that farmers be urged to maximize the practical usage of organics wherever feasible. On the other hand, it was also pointed out that many farmers may not have enough available to cover all their crop land. In such cases, chemical fertilizers are often very cost-effective if capital or credit is available. It's not unusual to receive a return of $3-$10 for every $1 spent on chemical fertilizers, especially when they're used along with other complementary management practices. However, chemical fertilizers require more skill to use than organics in terms of rate determinations, dosage calculation, timing, and placement.
