Maximizing profitability in your almond orchard starts with maximizing nut set every year. Achieving consistency in set and minimizing alternate bearing cycles is the key to consistent yields and higher profits. The secret is ensuring the tree has the right nutrients at the right time in the right forms and right mix. Nut set can be influenced by boron which [...]

Cold Climate grape cultivars are helping growers build a robust wine and tourism industry across many states, but this is a viticulture that requires a well-planned strategy for frost protection. Whether the frost arrives late in the spring as it did in 2012 or early in the fall as in 2011, growers know the risk is there. Each year more growers [...]

How can KDL help protect or minimize frost damage?  During spring, as plants begin to grow new green tissue, the demand for nitrogen is at its greatest. At this stage the nitrogen to potassium ratio favors nitrogen. During the fall, as fruit ripens and plants begin to “harden off” and prepare for winter, the demand [...]

Properly timed applications of Agro-K’s KDL®  0-0-24, can dramatically enhance brix, color development, and uniform maturity in all grapes. Increasing brix and color can improve juice phenolic compound levels resulting in measurable  increased wine quality. KDL’s unique formulation links potassium to a sugar complex that can quickly penetrate plant tissue – encouraging sugar development in the leaf and transport into the [...]

Sysstem® VT is a specialty formulated foliar fertilizer containing potassium, calcium, magnesium in a phosphite form as well as boron all powered by Symspray® to help maximize grain fill and mitigate heat or plant stress. Sysstem® VT is designed for pre-tassel use on corn and pre or early bloom on other crops to meet the peak nutrient demand timing [...]

Calcium is a critical nutrient in growing quality fruit and vegetables. Getting calcium into the crop during the fruit “cell-division” window is the key to improving crop quality, marketable pack-out and grower profitability. Maximizing calcium levels in the fruit will improve cell wall thickness leading to improved skin appearance, transportability and shelf-life. Every crop is different, but supporting each crop’s peak demand timing [...]

The best time to nutritionally impact next years almond crop is Hull Split and/or Post Harvest application timings. Many almond growers with late varieties or early leaf drop and/or who rely on custom spray application often find post harvest applications difficult logistically. Now growers have new stronger nutritional tools to make the Hull Split application just as effective [...]

First, Symspray® is a “stabilized” seaweed extract solution. The natural compounds (hormones) known as plant growth regulators (PGRs), which are found in all seaweeds, have a limited shelf-life. Agro-K has a unique stabilizing process that has shown to greatly improve the stability of these important compounds. Second, Agro-K uses Ascophyllum nodosom as its seaweed source. [...]

BioMax is one of the best, most efficient ways to improve soil biology and root environment. BioMax improves soil function in all cropping systems resulting in better root and plant health and increased soil nutrient efficiency. BioMax is a soil biological stimulator that increases aerobic bacteria (vs. anaerobic) and beneficial fungi, such as  ycorrhizae. BioMax contains specific food sources, […]

BioMax is the best, most efficient way to improve soil biology and root environment. BioMax improves soil function in all cropping systems resulting in better root and plant health and increased soil nutrient efficiency. BioMax increases beneficial microbial populations after fumigation and can be used for better establishment of new perennial crops. If increased soil health and resulting improvement in crop performance is what you need […]

Bio-Mulch accelerates crop residue break down and increases nutrient cycling and nutrient availability in the soil. Bio-Mulch is specifically designed to reduce crop residue build-up on the soil surface resulting in improved planting, seed placement and germination. How Does Bio-Mulch Work? Bio-Mulch is a unique blend of nutrients and fermentation enzymes designed to increase existing local populations of cellulose […]

KThe field on the left was treated with two quarts per acre of Sysstem-Ready. The field on the right is an untreated control plot showing signs of distress and a slower row close. It takes countless hours of research and continuous trial work to get the right potato nutrition regimen in place. Growers want proof. [...]

Honeycrisp apples are the hardest to grow and the most prone to difficulties. Bitter pit, a disorder most commonly linked to calcium deficiencies in the fruit, is one of those difficulties. And it can happen to anybody. It’s endemic to the Honeycrisp variety and growers are paying more attention to the risk factors that impact […]

Here’s something to ruminate on. Near Scottsbluff, Nebraska a farmer-rancher found over the last winter that his cattle preferred grazing Bio-Mulch™ 7-0-0 treated corn stubble so much that for a remarkably long time they wouldn’t even bother with the neighbor’s untreated half-pivot. And consider the production economics that resulted. The cattle required less supplemental feed […]

High-quality, high-yielding nut crops require a robust, healthy tree root rhizosphere where natural soil born organisms improve the availability and efficiency of soil fertilizers to complement fast-acting prescriptive foliar nutrition programs. Agro-K Corporation’s new BioMax™ Dual Action + feeds and activates native beneficial bacteria and fungi to make more soil nutrients plant-available and grower investment […]

Blueberry and cane berry growers who recognize the importance of the period just beyond fruit set and at the beginning of cell division have a chance to really enhance their upcoming yields. It is the period of time where individual cells in the fruit divide rapidly. This 3-4 week window is one of the most [...]
