California Wine Grapes

Rod Carlsen, District Sales Manager for California


Wine grapes are a major specialty crop in California, with over 575,000 bearing acres in production, according to the USDA's most recent (2021) statistics.      Whether the state is mired in drought (2020-2022 growing seasons) or well supplied with water (2023 is, thankfully), wine grapes require adequate potassium levels to ensure the ripening of a high-quality crop.   Potassium plays a host of critical roles in relation to plant metabolism and helping all crop types deal with abiotic stress, often manifested in the form of hydric (water) stress.  Hydric stress can be due to a lack of supply of irrigation water (e.g., 2020-2022 growing seasons) or intentionally brought about by deficit irrigation programs in which irrigation amounts are deliberately reduced to help ensure the winery is receiving harvested fruit with quality components (e.g., acidity, color, tannin) that are above-and-beyond the main fruit characteristics. 


According to the current edition of the "Western Fertilizer Handbook," published by the Western Plant Health Association, 13 pounds of K20 per harvested ton of fruit leave the vineyard for the winery crush pad.  For a high-quality vineyard yielding 5 tons to the acre, this equates to 65 pounds of K20/acre.   What complicates matters is that vineyard soil types vary widely in their ability to supply potassium to vines in California's key, growing regions. To name a few: deep sandy soils in pockets of the interior regions of the San Joaquin Valley and San Joaquin River Delta, to alluvial clay and gravel-rich riverbed soils in coastal California where potassium is often "fixed," or tied up in the clay lattice of the soil, to hillside volcanic soils that are often high in magnesium which antagonizes potassium uptake in the vine.   For these reasons, and many others not listed in the interest of relative brevity, growers must supplement their base potassium programs with in-season, liquid potassium applications through drip irrigation, foliar applications, or both.


NACHURS K-fuel® (0-0-24) is an ideal fit for supplementing base potassium fertility programs in the production of high-quality wine grapes.  K-fuel contains the highest concentration of our Bio-K® technology in the NACHURS product line.  It can be applied via drip, at 3-5 gallons per acre, post-fruit set through the early onset of veraison (berry ripening phase).   It can also be applied as a foliar at 2-4 quarts/acre with crop protection chemistry during the same vine physiology phases as with applications made to the soil. Potassium has partnering interactions with other vital nutrients for producing high-quality wine grapes, such as Calcium and Magnesium. When soil composition and chemistry are challenging (see prior paragraph), K-fuel can help the grower work around the soil challenges by first delivering the most soluble form of potassium (Bio-K) to the vine.  Secondly, the acetate molecule contained in Bio-K and K-fuel is an anionic (negatively charged ion) carrier that can transport other positively charged nutrients like Calcium and Magnesium into the vine that otherwise would be tied up in the soil. Thirdly, acetate is also a carbon-containing molecule that is a recognizable and usable food source for bacteria and fungi in the root zone to utilize to free up additional resident soil nutrition (e.g., released by mineralization and chelation). In sum, with NACHURS Bio-K products, specifically K-fuel for wine grapes, the grower is applying a product that provides a 3-for-1 value proposition which ultimately does MORE with less!   



Cheers!

We are at the point in the year where things are slowing down around the farm and it is time to reflect on the season to remind ourselves what we learned. Over the last couple of weeks, the District Sales Managers and I have spent some time reflecting on what worked well in the field and the challenges we faced too. Here are the top 5 things we learned from 2024 growing season: #1 Split applying Nitrogen and Sulfur is a practice that should be embraced on a yearly basis when growing corn. Do you remember how the planting season started and what happened in the first 60 days after the planters started rolling? Our field conditions started out dry with some areas of the corn belt showing up on the drought map. Then mother nature blessed us with rain that never stopped in some areas making it difficult to finish planting. Growers that had split applied their Nitrogen and Sulfur were able to avoid nutrient loss from the rain but also apply the nutrients when the crop needed it most. In the end yield was better on split applied nitrogen fields compared to fields that had all the N applied in the fall or spring before planting. #2 For the past 2 seasons in the North region, we have seen the benefits of adding NACHURS Humi-Flex FA to the in-furrow starter fertilizer. NACHURS Humi-Flex FA is our fulvic acid and it is becoming a valuable component in our starter fertilizer for many reasons. We are using it to chelate the nutrients in the starter fertilizer especially phosphorus. Humi-Flex FA also buffers the soil pH to neutral in that nutrient band keeping nutrients available in fields that have less then optimal pH for crop growth. Finally, we use Humi-Flex FA to create a healthy soil microbiome that leads to more root mass and nutrient uptake. #3 Nutrient uptake charts for corn and soybeans have been a great tool for our team to help our customers visualize the crops nutrient needs based on timing during the growing season.

Wayne Becker, District Sales Manager & Agronomy Specialist Blending two NACHURS products (Triple Option® and Balance®) at a 1:1 ratio has proven to jump start soybeans and increase profitability. Many farmers would like to use in-furrow starter fertilizer with their beans but are uncertain of the benefits. When beans are first planted early growth is very important. • It is a race against time between soybeans and weeds, fighting for water, sunlight and nutrients. • The quicker a canopy is established, the less weeds are able to steal resources, which could affect yield potential. Traditional In-furrow fertilization of beans is usually not as easy to visually observe as when it is applied to corn or wheat. However, that does not mean that they are not extremely important. This treatment will provide early season fertility that will help the young crop remain strong and vibrant, enabling them to better deal with stresses like insects, drought or water logging. NACHURS liquid fertilizer has been providing the best in-furrow fertilizer treatments for 75+ years. With NACHURS in-furrow, producers have always been able to safely provide the traditional benefits without decreasing germination because of the fertilizer’s low-salt content and superior availability. New focus on plant and soil health has raised the bar even higher. The NACHURS Bio-K® line of fertilizers is the most available source of K on the market, yet it also promotes both soil and plant health. Because the Bio-K fertilizer is a carbon molecule combined with potassium, applying it in-furrow provides beneficial soil microbes with a food source. This enables microbes to increase nutrient availability – for all types of crops. Legumes use Rhizobia to “fix” their own nitrogen. NACHURS has developed a product specially designed to stimulate early development of these important soil microbes. It is called Balance®. We combine the rhizobia stimulating qualities of Balance with Triple Option which maximizes quantity of other nutrients. The result is improved potential for early season growth and greater profitability of soybeans
