The problem with organic fertilizers is, "there is poor synchronization of nutrient availability and crop demand, as organic fertilizers release their nutrients slowly and not necessarily at the times when nutrients are required by crops". This means that growing organic coffee is slower because the nutrients take time to release, thus slowing the growth rate of the plant. Using inorganic fertilizers permits faster growth of plants because it is modified to sustain a larger yield. Inorganic fertilizers must be bought, brought onto the farm, as opposed to say recycled manure of cattle or chicken. Even though it must be bought, farmers are able to use less inorganic fertilizer because it is more concentrated than organic, but in the long run organic helps the soils and is healthier. Even though organic fertilizers are less expensive than inorganic, consumers see a higher price with organic coffee. Environmentally-conscious consumers may be willing to pay this premium.
