TECHNICAL INFO...

1. Differences in nitrogen on the labels:


1. Nitrate Nitrogen - is a soluble source of nitrogen that moves through soil easily and is readily available to the grass when applied. Nitrates are not extremely temperature dependent so foliar applications can work during cold or hot months. Nitrates are best used in the foliar form because over applying them in the granular form will cause increased leaching into the ground because of their soil solubility.
2. Ammoniacal Nitrogen - Some of the product is in the water soluble form, but most needs to be converted to the nitrate form by microorganisms in the soil. These are best used during warmer periods and they are often not available to the plant when applied early in the spring or late in the fall. They do help acidify the soil which makes it very useful with our high pH levels.
3. Urea Nitrogen - Water soluble nitrogen that goes into solution easily, but first must be converted to ammoniacal and then to the nitrate form of nitrogen before the plant can use. All this is done by microbes in the soil. Applying urea in the foliar form gives the plant a chance to use all of the Urea because it is applied in small doses. In the granular form the available nitrogen is quickly used leaving the unconverted nitrogen to denitrify and unavailable for later use.


2. Why do our products contain calcium and magnesium?


1. Calcium applications are necessary in soils with a high pH for the roots to absorb fertilizer. Foliar applications allow your roots to react to the available calcium as early as 4-7 days while granular calcium's take 3-4 weeks for the roots to absorb.
2. Calcium and magnesium are the catalysts that give our lawns early spring green up, and allow your roots to take up other important nutrients from the soil.
3. Magnesium, not iron is the core molecule in chlorophyll. Since our irrigation water generally contains no magnesium, foliar applications are needed throughout the year to maintain turf color.


3. Why use a foliar product versus a granular?


1. Foliar products can be applied in small dosages making all the nitrogen applied usable and will reduce leaching in the soil.
2. These foliar products contain the building blocks necessary for a deep root system, dark green color, and available nutrients throughout the year.
3. These foliar products are all non-staining, and have readily available minor nutrients that would take weeks to be available in the granular form.


4. What is the difference in the 7-7-7, 16-0-4, and 4-0-6?


1. 7-7-7 is a year round seasonal booster that provides quick release urea nitrogen and all the minor nutrients necessary to complete seasonal color deficiencies. Manganese and zinc are added to maintain plant color and supplement moderate soil deficiencies. This product can be used year round and will maintain a balanced soil.
2. 16-0-4 provides your turf with a foliar mix that is high in calcium for root absorption of fertilizer, and a blend of slow and fast release nitrogen to provide quick color that will last for 4-6 weeks. This is a combo of urea, nitrates, and ammoniacal nitrogen to ensure available nitrogen throughout growth period. The different forms of nitrogen breakdown slowly in the soil and become usable over 4-6 weeks. The 16-0-4 is ideally used in early spring for green up, during winter months to maintain color season grass color, or throughout the summer for a quick boost in plant strength.
3. 4-0-6 is a quick release nitrogen product that greens your turf within days and supplies the roots with the calcium and magnesium necessary to maintain proper soil pH. The high potassium gives the plant extra strength during the cooler winter months, hot months and late in the fall season. This is a great product to use during stress periods such as mid-summer to maintain a deep root system.
