Increasing Grape Yield: Switch to AgroLiquid

In grapes, a combination of variety, management, and training system dictates how much quality fruit the plant can produce. One of the best options is using fertilizer applied in the spring that can be easily taken up by the vine. Over the last four years, we have been looking at what AgroLiquid products can do on grapes. All fertilizer is soil applied in the spring underneath the vines.

  • Conventional Program: 12 gallons of 28%UAN + 12.9 gallons of 10-34-0 + 100 lbs. of sulfate of potash.
  • Agroliquid Program: 11 gallons of High NRG-N + 4.2 gallons of Pro-Germinator + 4.2 gallons of Sure-K + 1 gallon of Micro 500 + 0.125 gallons of Manganese.

Details about this project can be found in the 2015 Research Report.

Almonds and Potassium

Potassium for a Healthier Almond Crop  

Maintain potassium at adequate levels to enhance productivity and prevent deficiencies that reduce almond yields.

Almonds love potassium (K). They require large amounts of it to remain vigorous and productive, even more so than nitrogen. Each almond orchard is a unique environment, and different soil types hold varying amounts of K and release it differently, which can make it tricky to manage K effectively.

“Growers who want to maximize yields need to stay on top of their K applications,” says David Doll, University of California Cooperative Extension nut pomology farm advisor for Merced County. “Otherwise, deficiencies will reduce return bloom and decrease spur longevity, which affects yields over time.”

 Base Management Decisions on How Much K is Available to the Plant

Although most soils contain large amounts of potassium, relatively small amounts of it are in a form plants can use. Consequently, growers should base management decisions on how much potassium is available when the plants need it rather than on how much potassium is available in the soil.

Potassium uptake in almonds is linear, with as much as 70 to 80 percent of total uptake complete by mid-June. For almonds growing in soils with a low cation exchange capacity (capacity of the soil to hold on to essential nutrients), such as sandy soils and sandy loams, smaller applications made on a frequent basis ensure potassium levels remain at sufficient levels throughout the growing season. For heavier soils like clay, growers can stretch applications further apart.

 Replenish K Lost at Harvest

 University of California Davis (UCDavis) studies show that 76 to 80 pounds of potassium leave the orchard with every 1,000 kernels harvested. To sustain healthy crop production in the long term, growers must eventually replace any potassium that leaves the field at harvest time.

“Replacement of potassium that is lost at harvest is something growers should be working on throughout the year,” says Doll. “To accomplish this, more and more farmers are combining dormant-season banding practices with in-season applications.”

 Prevent Deficiencies with Continued Monitoring

Deficiencies develop gradually over time and visual symptoms can take years before they show up. Plants lacking in potassium often show delayed or stunted growth. Other deficiency signs include inward curling of leaves, discolored leaf tips and marginal scorching. When severe, potassium deficiencies can increase the loss of fruiting wood, which results in reduced crop loads.

Continued monitoring and fertilization in the orchard helps growers build and maintain K at levels where deficiencies are less of a concern. Regular soil testing, taken a minimum of every three years, can help almond growers identify nutrient trends over time, additionally annual leaf samples help growers keep track of K levels.

“Mid-July leaf samples work well because tissue levels are relatively stable at that time of year,” says Doll. “Take two to three leaves from five non-fruiting spurs for at least 15 to 20 trees across the block. Trees should be 100 feet apart. To maintain sufficient levels across the orchard, UC Davis recommends  shooting for a target potassium level of 1.6 to 1.8 percent.

 Agro-Culture Liquid Fertilizer Potassium Products

Sure-K® is a clean, chloride-free potassium solution engineered for maximum plant uptake. It has a neutral pH, making it ideal for application with most crop protection products.

Kalibrate is an enhanced-efficiency potassium fertilizer formulated with the added benefit of 6% sulfur. While nitrogen, phosphorous and potassium are generally applied to crops in the greatest quantities, including the other nutrients like sulfur are keys to optimal plant growth.

 In cases where it is customary to split seasonal fertilizer needs into a number of smaller applications, Kalibrate may be used for early-season potassium, while Sure-K may be more appropriate for mid- to late-season foliar applications.

While the objective with any fertilizer application is to apply plant available nutrition, many fertility products also contain elements that can have a negative impact on the soil and plant health. The lack of chorine and a near neutral pH found in the AgroLiquid’s family of products makes them a more sustainable option in plant nutrition.

Almonds and Nitrogen

Step-up Almond Yields with Effective Nitrogen Management

Proper nitrogen management enhances almond yields, promotes healthy tree growth and benefits the environment.

The key to nitrogen management for almonds is to meet crop demand without going overboard. This involves timing nutrient applications to meet the needs of the crop so nutrients are not lost to leaching and denitrification. Nitrogen is essential to the healthy growth and development of almond trees and has a direct impact on yields. In the end, proper management of this essential element pays handsome rewards, both in yields and in preservation of the environment.

Crop Demand Guides Nutrient Applications

Effective nitrogen management for almonds involves letting crop demand guide the timing of applications to ensure nitrogen is present in the root zone when the crop uptake will be most efficient. Split applications work well because growers can time them to match high uptake periods.

“Almond trees use a majority of their nitrogen from leaf-out to kernel fill. We recommend applying 80 percent of the total nitrogen budget by that point,” says David Doll, University of California Cooperative Extension nut pomology farm advisor for Merced County. “After leaf expansion, the nitrogen growers apply goes into the developing kernel. Once kernel fill is complete, it is best to back off on applications until the post-harvest period, and then apply another 20 percent of the nitrogen budget post-harvest.”

Doll cautions that growers should not exceed 50 pounds of nitrogen in the fall because the crop can’t effectively use more than that amount and the excess can be lost to leaching.

Nut Yield Influences the Nitrogen Budget

Nut yield is a major determinant of nitrogen demand in mature almond trees. Depending on yield, a large portion of the total nitrogen a tree takes up in a given year goes into the nuts, while a much smaller amount fuels tree growth. According to Doll, 65 pounds of nitrogen are removed with every 1,000 kernel pounds.

To be accurate, growers must base nitrogen budgets for the current crop year on expected yield, minus additional inputs such as nitrogen-rich cover crops, compost and nitrogen in the irrigation water. Growers also need to look at the efficiency of the nutrient.

“Nitrogen has an efficiency factor of 70 percent,” says Doll. “This means that you have to apply around 85 pounds of it in order to get 65 pounds into the ground. Growers need to make sure they are figuring this into their nitrogen budgets.”

Agro-Culture Liquid Fertilizers Offers Solutions with Advanced Nitrogen Products

Balancing crop demands with increased accountability over the uncertain fate of nitrogen makes is imperative that growers constantly evaluate their nitrogen management. Agro-Culture Liquid Fertilizers recognizes the challenges almond growers face when managing nitrogen inputs. Their N-Suite of products offers solutions with greater nitrogen efficiency as well as a way to improve the efficacy of many conventional materials.

Three powerhouse products, High NRG-N, NResponse and eNhance, provide greater nitrogen efficiency and application flexibility, while still maintaining the overall health and yields desired from your almond trees.

Use Liquid Fertilizer for Long-Lasting Strip-Till Applications

Strip-till applications are the perfect time to place liquid fertility where the crop needs it, with the assurance that nutrients will be available when and where you need them.

Strip-till combines the best features of no-till and conventional tillage systems. Tilled strips that will house the seed row reside alongside undisturbed bands of crop residue that shelter the soil and conserve moisture. Growers who want to practice Responsible Nutrient Management, have poorly drained soils or are apprehensive about areas with poor soil structure can benefit from using strip-till in their operations.

Strip-till accelerates the warming and drying of the soil in the spring, which stimulates earlier and deeper root growth in field crops such as corn. It can also increase air circulation and improve aerobic conditions.

One of the biggest advantages of strip-till is that nutrients can be placed into the root zone where there is less potential they will be diverted or immobilized by crop residue. Dual placement of phosphorus (P), potassium (K) and micronutrients near the seed zone and placement of nitrogen beneath the seed zone, improves the proximity of nutrients to the roots as they grow and develop.

Successful strip-till applications match the right nutrients with the right timing, according to geographic area. For example, it isn’t advisable to apply nitrogen in the fall in areas that have large amounts of rainfall because of the potential for leaching. However, in arid areas growers can successfully apply nitrogen in the fall.

An effective combination for strip-till applications is Pro-Germinator for phosphorus and Sure-K for potassium, along with microLink for balanced micronutrient application. For nitrogen applications, AgroLiquid offers a number of choices from their N-Suite to meet the needs of any strip-till situation.

Agronomists at the North Central Research Station in St. Johns, Mich., conducted a two-year trial that assessed the effect of fertilizer timing and placement on strip-till corn (2012 Research Report, Effect of Fertilizer Timing and Nutrient Placement in Nutri-Till/Strip-Till Corn).

Strip-Till 2012-Research-Report-18_GraphResearchers found that deep fall placement was only slightly lower in yield than shallow fall placement. And both spring and fall placement of P, K and micronutrients resulted in similar yields. The study also established that the highest yield for both years was where all of the fertilizer was applied in the spring with the strip-till operation. This treatment resulted in corn that was noticeably ahead of the other treatments.

Growers are often apprehensive about nutrient applications during fall strip-till because they worry nutrients will not be available for crops the next year. AgroLiquid product formulations promote stability and protect nutrients from tie-up and loss. They are a great fit for conservation tillage cropping systems. Best of all, growers can apply fertilizer with confidence during strip-till, having the peace of mind that nutrients will be available at the right time and in the right place.


Effectiveness of Side-dressing

Side-dress is a great time to apply the potassium and micronutrients that your crop may be missing. If you didn’t get potash applied last fall, maybe the weather changed your fertilizer strategies, or you aren’t set up to apply liquid on your planter and want to balance your fertilizer program with needed micronutrients. Maybe you want to push this season’s crop to a higher level of yield potential. AgroLiquid’s Sure-K and microLink products allow you to nutritionally balance your side-dress nitrogen application efficiently and economically.
