Some organically-based fertilizers, such as PHC All-Purpose Fertilizer, also contain small amounts of synthetic fertilizers to ensure the availability of nutrients. For the long-term health of your garden, feeding your plants by building the soil with organic fertilizers and compost is best. With the exception of nitrogen and phosphorus, most alkaline, clay-type soils usually contain enough of these elements for vegetable production. In acid sandy soils, nitrogen, phosphorus, potassium, calcium, magnesium, and, at times, sulfur and boron may need to be added for successful crop production. The Organic manures are sometimes placed on the surface of the soil and incorporated into the soil with a plow or rot tiller before planting. Fertilizer can also be applied in bands at the bottom of plough furrows or broadcast or spread on top of plowed soil that is then worked into the soil with a harrow before planting of all the major fertilizer nutrients, nitrogen is the main nutrient affecting soil pH, and soils can become more acidic or more alkaline depending on the type of nitrogen fertilizer used. … Phosphoric acid is the most acidifying phosphorus fertilizer. – Potassium fertilizers have little or no effect on soil pH.
