Are you seed-placing your phosphorus (P) and basing application rates on seed safety rather than crop requirements? You may be leaving yield on the table. Recent research out of the University of Manitoba examining seed-safe rates of P and sulfur (S) in canola is showing that P applied at rates based on seed safety may not be adequate to maximize canola yields.
Nitrogen (N) is one of the most widely distributed elements in nature, since it’s the most abundant gas in the atmosphere. While N isn’t found in mineral forms like phosphorus (P) or potassium (K), it’s largely present in organic compounds. Soil-based N undergoes many complex biological transformations that make it challenging to manage.
Many soils require adding several essential nutrients to alleviate plant deficiencies. Farmers may opt to select a combination of single-nutrient fertilizers or apply a fertilizer that combines several nutrients into each particle. These combination fertilizers (compound or complex) can offer advantages of convenience in the field, economic savings and ease in meeting crop nutritional needs.
Catch the drift of ammonia. With the renewed emphasis on getting the most benefit out of fertilizers, no one wants to lose ammonia from applied N fertilizer.
Ammonia (NH₃) is the foundation for the nitrogen (N) fertilizer industry.
