Calcium on Apples

Why is calcium important?

Calcium is the third most important element in a plant. And, calcium is the fifth most abundant element on the planet. It makes sense that traditionally, growers don’t apply much calcium, because they assume the plant will get what they need from the soil. But, calcium is usually found in a form that is not easily taken up by plants.

In an apple tree, the leaves, new shoots, and fruit all take calcium and the nutrient will be found in the tissues and the root, but, the fruit cannot compete with the other parts of the plant hence why the fruit often doesn’t get enough calcium. That is why calcium deficiencies are evidenced on the fruit, rather than the rest of the tree. In apples, a calcium deficiency causes a disorder known as bitter pit. Bitter pit is a physiological breakdown of the cell walls in the fruit that occur below the skin of the fruit. For that reason, when scouting for calcium deficiencies, it is important to test the fruit, rather than relying solely on leaf or soil tests.BMSB.-Bitter-Pit-1h84hub

In this particular trial, Horticulturists were testing for fruit firmness, how many apples produced on each tree, and how much the fruit weighs. At the North Central Research Station High-Density Apple Orchard, researchers test approximately 10 apples per experimental plot for firmness. They use a pentameter, which measures the pressure needed to break the cell part inside the apple. They test four spots on each apple, as research has shown there is a difference in firmness between the side of the apple exposed to sun, versus the shade-side. The average fruit firmness is reported.

A trial of the effects of LiberateCa™ in 2015 at the NCRS High-density Apple Orchard in Michigan showed that the apples treated with LiberateCa™ fall close to the preferred range of 14.5 lb – 17.5 lb for fruit firmness, while the untreated trees’ fruit firmness was significantly higher than desired. In addition, the treated trees had more apples per tree, and overall yield per tree increased as well. These trees were planted at 3 ½ feet between trees, 11 feet between rows, with a planting density of 1,100 trees per acre.Ca on apples

“If you can hang two more apples per tree, with 1,100 trees, you have 2,200 more apples – and that means more money in your pocket.” Horticulturist Jacob Emling

CA on Nitrates & Water Quality

Take-Home Lessons from California on Nitrates and Water Quality
California water coalitions are leading the way in addressing nitrate contamination. What can growers learn about nitrogen management from their progress?

Nitrate contamination is one of the biggest threats to water quality in our nation, particularly in California, where it affects vast areas of irrigated farmland. As farmers in California go through the regulation process, what are they learning and how can other growers benefit from their experience.

The Proof is in the Data
One thing California growers will have to do in the near future is track and report their nitrogen use. Parry Klassen, fruit grower and executive director of the East San Joaquin Water Quality Coalition, was part of the Department of Food and Agriculture committee tasked with developing an approach for farmers to track nitrogen use and report information to aggregators.

“I believe that nitrogen tracking and reporting will help us better define what we in agriculture already do with nitrate fertilizers,” says Klassen. “Ultimately, what growers will have to do is prove to the regulators that we are taking steps to manage nitrogen properly. I say this because I believe many growers are following best management practices. We just don’t have the data to prove it.”

Know Your Water
As part of the tracking process, farmers in California are testing their irrigation and well water for nitrates and accounting for those levels in their annual fertilizer budgets, a good practice for any grower looking to reduce nitrate leaching.

“The amount of nitrates in well water is site specific and varies according to region,” says Klassen. “In the East San Joaquin area, we have a lot of nitrates in our well water, some areas have the equivalent of 50 nitrogen units per season. If you need 300 pounds of nitrogen for your crop, you would plan on putting out 250 to account for the 50 in your groundwater.”

In addition to testing water supplies, California growers have implemented basic agronomic practices that are long-proven methods to help reduce nitrogen leaching.

Back to the Basics
“We often focus too much on sustainability at the expense of going back to basic agronomic practices for nitrogen management,” says Klassen. “For example, proper timing of nitrogen application based on crop demands and matching fertilizer rates to individual crops.”

Other examples — split applications to spread nitrogen use out over the consumptive period for better efficiency and uptake, soil and tissue analysis, the use of drip and micro systems for spoon feeding the crop and nitrogen budgets based on known crop consumption levels.

While there are several best practices for nitrogen management, nothing is a one-size-fits-all solution. It often takes a combination of several practices, tailor-made to site-specific conditions, to effectively reduce nitrogen leaching.

Responsible Nutrient Management
Much of effective nitrogen management boils down to managing nutrients responsibly by using less fertilizer applied, taking advantage of precision placement, utilizing prescription programs and applying balanced formulations that include micronutrients. Agro-Culture Liquid Fertilizers is an advocate of Responsible Nutrient Management®, which incorporates these principles.

In California and elsewhere, AgroLiquid recognizes the challenges growers face in trying to manage nitrogen for maximum uptake by the crop. Their N-Suite of products, High NRG-N, NResponse and eNhance, offer a wide variety of application options to support nitrogen management practices and effectively meet the cropping needs of the grower.

Soil Fertility and Success

An important part of evaluating your fertility program is to identify existing problems or limiting factors that are restricting yields and make plans to correct them. An annual review is essential. What worked one year might not work the next year. Agro-Culture Liquid Fertilizers can subscribe a growing program that is right for your farm.

(Webinar) Getting More For Less From The Fertilizer You Apply

No-tillers can’t afford to waste money on applied fertilizer. Neither can the agriculture industry continue to watch these resources negatively impact watersheds without expecting possible severe regulations. Nobody knows that any better than no-tiller Mike Starkey of Brownsburg, Ind., whose farm lies right at the base of the Eagle Creek Watershed that supplies the city of Indianapolis its drinking water.

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.


Soil Testing

Maintaining a healthy balanced soil requires consistent effort and advanced planning. This is the best way to determine how much nutrition is available to feed your crops from planting to harvest. Create a custom fertility program that pushes your yield to the max. Agro-Culture Liquid Fertilizers has a variety of products to help you maintain a healthy balanced soil.

June Strawberry Production

Start strawberries off right with AgroLiquid fertility products

Growers have a short time window to establish plantings once June-bearing strawberries are in the ground. In the fall, strawberries will require large amounts of energy for bud formation, a process that will shape yields for the next year.

Can AgroLiquid products help increase yields for commercial strawberry production? Research proves they can.

AgroLiquid Strawberry Trial Results

Agronomists at Agro-Culture Liquid Fertilizers compared their liquid fertility program to a conventional one to see what the effect would be on the yields of June-bearing strawberries.


Harvest results show that greater yield is achievable with less actual fertilizer applied. This not only results in cost-savings, but also provides a positive environmental benefit in the sandy soils where strawberries are commonly grown.

The AgroLiquid program out-yielded the conventional fertility program on three out of four individual harvests and when all four measured harvests were combined (See Figure A1). The most significant result was in nutrient use efficiency, which was three times greater for the AgroLiquid program.


Nutrient Needs for Strawberries

AgroLiquid products, with their unsurpassed application flexibility and research proven performance, can provide a strong nutritional foundation for June-bearing strawberries. Whatever the nutrient need, AgroLiquid has a product that offers quick, effective results.

  • Nitrogen – Nutrient demands for strawberries escalate in the fall. A majority of nitrogen should be applied prior to flower bud formation for optimal yields. High NRGN™ is a multi-form nitrogen fertilizer with one percent sulfur for effective, season-long nitrogen availability (27-0-0-1S).
  • Phosphorus – A certain amount of phosphorus is necessary for strawberries to develop strong fruits and healthy roots. Pro-Germinator™ is a high quality, dual-form phosphate fertilizer, 30% is available for immediate uptake. The remaining 70% has superior usability well into the growing season (9-24-3-0.1Fe).
  • Potassium – Potassium influences fruit development and fruit quality, as well as water movement and enzymatic processes within strawberry plants. Sure-K™ provides a versatile, chloride- and hydroxide-free potassium source for extremely efficient results in all cropping environments (2-1-6).alcium – Inadequate watering or rain and a lack of calcium can cause blossom end rot in strawberries.
  • Calcium also plays an important role in fruit development, in particular fruit firmness, which means plants hold up better during shipping. When extra calcium is necessary, LiberateCa™can be tank mixed with Pro-Germinator™, Sure-K™ and all micronutrients for maximum application and placement flexibility.
  • Micronutrients – Strawberries need small amounts of micronutrients for healthy growth. For example, boron is necessary for good fruit set and iron for the production of chlorophyll.Micro500™ is a proprietary formulation of zinc, manganese, iron, copper and boron that maximizes micronutrient efficiency (1.8%Zn, 1.2%Mn, 0.37%Fe, 0.25%Cu, 0.02B).
