FREE pHOS 24 & pH

Sub Title:
Why is FREE pHOS 24 spelled the way that it is? Because pH is very important when it comes to phosphate availability in the soil. First, we should define what pH is. In scientific notation it stands for the potential of hydrogen. It is defined as the negative log of the hydrogen ion. It has [...]

Phosphorus

Sub Title:
How much phosphorus is in soils? There is about 1,000 parts per million of phosphorus in the earths crust. However, phosphorus is never found by itself in the environment, it is always attached to other elements. So, if there is 1,000 ppm, then there is about 2,000 pounds of P in the top six inches [...]

Phosphate

Sub Title:
There are three plant nutrients that can not be totally supplied to the plant thru foliar applied nutrients. These three are calcium, potassium and phosphate. In our soils in western Oregon, the only one that we have plenty of is potassium. Since our soils are acidic, we are constantly needing to apply calcium carbonate. The [...]

Nutrient Interaction

Sub Title:
When we apply fertilizer for crop production, we should be focused on getting our soil in balance. The biggest problem that I see is that growers think that if there is a problem, they need to apply a large dose of a nutrient. This is usually nitrogen, but it could also be phosphate or potassium. [...]

Plant Nutrients That Can’t Totally Come From a Foliar

Sub Title:
There are three nutrients that can’t totally be supplied by applications of foliar sprays. The three are calcium, potassium and phosphorous. The reason is that it takes a very large amount of these nutrients available in the soil for normal plant growth. On a Morgan test, there should be a minimum of 1800 pounds of [...]

Soil Sampling

Sub Title:
When is the best time to take a soil sample? The best answer that I have is to ask what you want to see from the soil. If you take it after harvest, the soil will be at its lowest levels because the plant have depleted nutrients. If you wait until spring, the levels will [...]

FREE pHOS 24 Trial

Sub Title:
We just got the results from one of our trials on FREE pHOS 24. I was on field corn and the products were both applied as a pop up directly on the seed at planting. The grower applied 9-24-3 at 5 gallons per acre and the FREE pHOS 24 at 3 gallons per acre. The [...]

Why Don’t Foliars Work Every Time?

Sub Title:
Have you ever noticed that one time a foliar works and the next time or in a different field it doesn’t? Here are a few reasons why you may have the problem. You should have a minimum of 1800 pounds of plant available calcium as reported on a Morgan test. The only lab that I [...]

Soil Applied Potassium

Sub Title:
What form and when should potassium be applied to the soil? The best answer to this question can be found in an article found on our website “Potassium Paradox.” It is a very interesting report that discusses what results can be obtained by apply KCL to the soil. I would encourage anyone who is making [...]

Diagnosing a Nutrient Problem

Sub Title:
Last week I got an email from a customer who was doing some pot trials on different soil applied phosphate products on wheat. He had several in his trial including our FREE pHOS 24 and he noticed that the leaf tips were turning yellow and brown. The leaves on the FREE pHOS 24 were worse [...]

Plant Nutrients for Free!

Sub Title:
How many of you think that you can get something for nothing? Usually, if it looks too good to be true, it probably is, correct? Well, let’s take a look at plant essential nutrients. If a plant is dry ashed and analyzed, what are the top three nutrients and how much of the plant do [...]

When Should Phosphate be Applied to a Crop?

Sub Title:
When we think of applying phosphate, we always think of it as a nutrient that is used early in a growing plant. This is, as we all know, a nutrient that is essential for root growth. As I am sure you are aware, all nutrients have many functions in a plant. Phosphate is also very [...]

Phosphate and Plant Maturity

Sub Title:
One of the roles of phosphate in a plant is to hasten plant maturity. The less available phosphate to the plant, the longer it takes for the crop to become mature. This was very clearly shown in a recent field where FREE pHOS 24 applied as a starter pop up fertilizer compared to a competitor [...]

What is a Mulder’s Chart?

Sub Title:
What is a Mulder’s chart and why would you want one? First off, it has nothing to do with a tv show or a person called Fox Mulder, but it may look like something from out of this world. What it does do is to show the inter actions of nutrients and how they affect [...]

What Can FREE pHOS 24 Do for You?

Sub Title:
I know that there are not many growers who raise tomatoes. However, please look at a photo from a recent trial where we compared FREE pHOS 24 against a competitive product. Notice the difference in root growth and plant size. The photo speaks for itself! Not only will it work on transplant tomatoes, but any [...]

FREE pHOS 24

Sub Title:
Why did we name this product FREE pHOS 24? Soil applied phosphate is terribly inefficient. Only about 5% to 10% of what is applied to the soil is available for use by the plant. That is because in soils with a pH that is acidic (below 7), some cations such as aluminum and iron are [...]

Soil Nutrient Application for Deciduous Fruit and Nut Trees for August

Sub Title:
This is the month for stone fruit and nut orchards to have 200 pounds per acre of sulfate of potash magnesia applied. This is for orchards that have signs of gumming coming from the bark. This condition is found in trees such as cherries, peaches, and almonds. This is called pseudomonas, xanthomonas or many other [...]

The Benefits of Copper as a Nutrient

Sub Title:
Copper is the most misunderstood of the essential nutrients. Some of its functions are to help with pollination, making the bark and outer layers of plants more flexible for better nutrient flow, cell wall lignification, and color and flavor of fruits. Copper also helps the plant fight off some diseases. An over-application of nitrogen or phosphate blocks [...]

Cherry Fruit Development

Sub Title:
In the first 25 to 30 days of cherry fruit development, after full bloom, every cell in the skin of the cherry is formed. If you do not have the correct nutrients in the skin as it is formed, then you can get rain induced fruit cracking. These nutrients are not mobile in the plant, [...]

An Answer to the High Cost of Phosphate Fertilizers

Sub Title:
Are you concerned over the high cost of phosphate fertilizers? Soil applied phosphate is only 5% to 10% effective, which makes a pound of phosphate fertilizers really expensive. It is tied up in the soil with iron and aluminum in low pH soils and with calcium in high pH soils. An article in the recent [...]
