How to reduce Fertilizer costs | Doggett Corporation

Reducing Costs We all know the cost of doing business is ever increasing.  Fuel costs, labor, equipment is at all-time highs.  Fertilizer components are no exception.  There are some ways you can somewhat help get the most out of your plant nutrient dollar, stay competitive and profitable. Consider the plant species you are feeding. Also consider the immediate environment, soil type, pH, and is it very wet or dry.  Taking a soil test can help determine what nutrients are lacking or in excess. Another way to determine nutrient needs would be to take foliar tissue test during the growing season.  By doing this you can figure out what specific nutrients the plant needs. When considering a fertilizer formulation, don’t look for the cheapest products out there.  Consider what product will give the best results and return on your dollar.  Look...

Micronutrients  are plant nutrients essential for optimum plant growth, but required in small amounts. Most complete fertilizers contain 6 micronutrients, and the percentage of each is critical to prevent toxicities and/or deficiencies. These include: 1: Boron (B) – Aids in the differentiation of plant cells, and also regulates the metabolism of carbohydrates. 2: Copper {Cu) – Activates several essential enzyme systems in plants. 3:  Iron (Fe) – Required for the formation of chlorophyll, and also controls the synthesis of indoleacetic acid, a plant growth regulator. 4:  Manganese (Mn) – Assists iron in chlorophyll formation.  High levels of Mn may induce Fe deficiency.  This symptom is sometimes called Mn toxicity. 5:  Zinc (Zn) – An essential component of several enzyme systems.  Like Fe, it also controls the synthesis of indoleacetic acid. 6:  Molybdenum (Mo) – Required by plants for utilization of...

Manganese (Mn) in Trees & Shrubs

Manganese (Mn) plays an important role in plants..  Considered a micro-nutrient, it is one of the essential nutrients required for growth. Plants depend on it to aid in photosynthesis, chloroplast formation, nitrogen metabolism and synthesizing enzymes. Tissue testing is an excellent way to determine if a tree or shrub is Mn deficient.  Certain trees are inefficient in utilizing Mn. Even though it can occur in any plant species, the most common are pin oaks, maples, dogwoods and river birches. Signs or symptoms would be pale green or yellow leaves with darker green veins. Mn deficiency is a serious, widespread plant nutritional disorder.  It is often found in dry, well-aerated and calcareous soils, as well as in soils containing high amounts of organic matter.  Bio-availability of Mn can decrease far below the level that is required for normal plant growth To...
