Stablized Nitrogen (SNT)

Stabilized nitrogen is a management tool that slows the rapid release of nitrogen. Nitrogen is the primary element in any turf grass and landscape management program. Nitrogen is expensive and also requires frequent re-application due to leaching and volatilization. . This extends the time of nutrient availability to the plant. This then reduces the number of applications, saving both valuable time and money. Stabilized nitrogen (SNT) works in 2 ways: 1. Urease, an enzyme, slows the conversion of urea to ammonium. By slowing this conversion, it retains more nitrogen as plant available ammonium. The less N converted to ammonia gas, the less lost to volatilization. 2. Nitrification inhibitors work by slowing the microbial conversion of ammonium to nitrate. This helps prevents leaching of N along with the reduced volatilization.

Micronutrients

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...
