This product is a highly concentrated health food for plants, which makes it a no-brainer for savvy AGGRAND users. So, here's some information we hope will make it another one of the must-have pro ducts in your AGGRAND stable. AGGRAND developed Natural Kelp and Sulfate of Potash as a primarily potassium- and sulfur-based product for foliar applications and potassium supplementation.
Powerful Ingredients for Plants
Kelp provides growth hormones, trace minerals and potassium. When applied to wine grapes, studies show that kelp extract increases yield, disease resistance and wine quality. Sulfate of potash provides a balanced source of potassium and sulfur readily absorbed by plants. Fulvic acid helps usher other nutrients into the plant via a process called chelation, and humic acid provides increased microbial activity in the root zone.
Plants need potassium to develop thicker cell walls and stronger stalks, helping to avoid and insect mouthparts. This helps protect plants from disease and damage, both in the field and after harvest. Potassium also can be absorbed more readily through the leaf cell walls than the other macronutrients, and when combined with the sulfur in the Natural Kelp and Sulfate of Potash, creates an ionically balanced nutrient combination more easily used by plants in both root and foliar applications. Sulfur is critical to nitrogen fixation and photosynthesis, and in the formation of proteins and oils, so it is important in the development of high nutritional value in legume forages like alfalfa and cover, as well as higher quality and extended shelf life of fruits and vegetables.
'You Will See a Difference'
What all this means for you is plants that are more vigorous, more tolerant of heat and drought (thicker cell walls) and more nutritious (better protein synthesis).
Natural Kelp and Sulfate of Potash can be mixed with water at a fairly low concentration (1 percent to 2 percent) and be quite effective. Plants can absorb nutrients up to 20 times faster through the leaf cuticle than through the roots, though in significantly smaller quantities; however, it is enough to promote a significant response.
Growers can either apply AGGRAND Natural Kelp and Sulfate of Potash on a calendar basis (every 2 weeks), or on the basis of the plant's stage of development: first true leaves, budbreak, flowering, etc. Just check the AGGRAND crop or garden guide (G2793 and G1292, available here for the specific application. If you aren't sure, apply bi-weekly for fast-growing plants or monthly for perennial crops.
A great method for foliar application of AGGRAND Kelp and Sulfate of Potash is using a hand pump or backpack sprayer. Just mix about 2 ounces Natural Kelp and Sulfate of Potash per gallon of water and soak as much of the leaf surface, top and bottom, as possible with the solution.
