| Importance of the Fertilizer | Compound fertilizer contains multiple nutrients in each individual granule. This differs from a blend of fertilizers mixed together to achieve a desired average nutrient composition. This difference allows compound fertilizer to be spread so that each granule delivers a mixture of nutrients as it dissolves in the soil and eliminates the potential for segregation of nutrient sources during transport or application. A uniform distribution of micronutrients throughout the root zone can be achieved when included in compound fertilizers. |
| Amount of Available Nutrients | Factomphos contains 20 % Nitrogen, 20 % Phosphorous, 0 % Potash and 15 % Sulfur. |

| Reaction of the Fertilizer in Soil |
Compound fertilizers are
sometimes more expensive than a physical combination or blend of the primary
nutrient sources since they require additional processing. However, when a
consideration is made of all the factors involved with nutrient handling and
use, compound fertilizers may offer considerable advantages. Nitrogen is the
nutrient that most commonly needs to be carefully managed and reapplied
during the growing season. It may not be feasible to supply sufficient N in
advance of planting to meet the entire demand (using only compound fertilizer) without over applying some of the other nutrients. It may be advisable to use a compound fertilizer early in the growing season and then later apply only N fertilizer as needed. Compound fertilizers are usually produced regionally to meet local crop needs. There is a wide range of chemical and physical properties that can be adjusted to meet these needs. For example, a desire to minimize P in urban storm water runoff has led some communities to restrict the addition of P to compound fertilizers sold for turf and ornamental purposes. Soils of a region that are typically low in a specific nutrient may have this element boosted in the compound fertilizer. |
| Situations where Recommended | These fertilizers are especially effective for applying an initial nutrient dose in advance of planting. |
