If choosing an organic formula is important to you, be sure to pick a brand that’s certified by a board like the Organic Materials Review Institute (OMRI). One major advantage of organic fertilizers is that they continue to work as the growing season progresses. They are sold commercially but can also be formulated with household scraps and ingredients like coffee grounds. Organic fertilizers only contain natural ingredients.Both types of formula have advantages and disadvantages. Plant fertilizers are made with either organic or inorganic ingredients. Be sure to choose a fertilizer that’s high in nitrogen for subsequent side-dressing. Corn is a heavy feeder and needs a high quantity of nitrogen to thrive once it is established. This will ensure they develop a healthy root system and have strong stems and foliage. Pre-planting fertilizers for corn should have NPK ratios of 1-4-0, 1-3-1, 1-3-3, or 1-1-1 to ensure they don’t contain too much nitrogen. These three macronutrients-nitrogen (N), phosphorus (P), and potassium (K)-are needed in varying quantities depending on the period of the corn plant’s life cycle. Plant fertilizers are typically rated with an NPK ratio which lists the balance of macronutrients found in the formula. Many fertilizers, however, contain ingredients meant to boost acidity for acid-loving crops, and unless your soil is extremely alkaline, you should avoid fertilizers that contain ingredients like manganese, ammonium sulfate or sulfur-coated urea, which increase acidity. In many parts of the country, no pH amendments will be needed to successfully grow corn. Soils that are too acidic should be treated with lime in the fall before planting to ensure the best results. The best soil for corn is slightly acidic at 6.0 and neutral at 7.0. It’s essential to test the soil’s pH level before planting by using a home pH test kit or having it professionally evaluated. Granular fertilizers slowly release nutrients over time, only requiring application every 4 to 6 weeks. Granular fertilizers are a great choice for fertilizing after seeding-otherwise known as side-dressing-because they can be applied to the soil without accidentally being applied to the plants themselves.Since liquid fertilizers can easily be diluted, however, it’s easy to avoid overfertilizing when using them. They deliver immediate results, but the primary downside of liquid fertilizers is that they need to be applied frequently at 1- to 2-week intervals. Liquid fertilizers are typically designed to be diluted with water and sprayed onto plants or soil.
