Osmocote® Iron, featuring unique E-Max Release Technology, is designed to maximize nutrient efficiency by supplementing iron and sulfur levels for high iron demanding crops, high root zone pH’s, high alkaline waters, and situations based on media/tissue testing where iron levels are shown to be deficient.
The following application rates are intended for general container greenhouse production and nursery stock growing conditions. Product and rate selection should always be based on individual grower practices and environmental conditions. Some factors that influence selection include:
SURFACE APPLICATION RATES PER CONTAINER (GRAMS) | |||
Common container sizes (Volume) | Approx. No. of containers per Cubic Yard** | Low | High |
Trade 1 Gallon | 300 | 2 | 3 |
1 Gallon | 210 | 2 | 4 |
Trade 2 Gallon | 125 | 4 | 7 |
2 Gallon | 102 | 4 | 9 |
3 Gallon | 70 | 6 | 13 |
5 Gallon | 52 | 9 | 17 |
7 Gallon | 35 | 13 | 26 |
Larger Containers | Surface Area in Sq. Ft. | Low | High |
10 gal. - 17 in. diameter | 1.4 | 16 | 31 |
15 gal. - 17.5 in. | 1.5 | 17 | 34 |
20 gal. - 21 in. | 2.3 | 26 | 52 |
25 gal. - 22,5 in. | 2.8 | 31 | 63 |
30 gal. - 26,5 in. | 3.8 | 43 | 85 |
45 gal. - 30 in. diameter | 4.8 | 54 | 108 |
Other larger containers - use these rates multiplied by actual container surface in sq. ft. | 11 | 22 |
INCORPORATION RATES | Low | High |
Lb. per cubic yard | 1 | 2 |
Kg. per cibic meter | 0.6 | 1.2 |
Grams per liter | 0.6 | 1.2 |
Osmocote Iron should be initially incorporated for plants grown in artificial/soilless media when possible. When upshifting to larger containers, application rate applies only to incremental growing media used. Mixing efficiency is improved if soil medium is dry prior to incorporation.
Osmocote Iron can be applied to the surface of the growing media or soil contains insufficient micronutrient levels. Broadcast granules as uniformly as possible over soil surface. Avoid piling product against leaves and stems. Water in immediately after application.
