In order to know how much fertilizer you’re going to need to purchase and what the cost per square foot will be, you have to have some idea of what the application rate and frequency schedule would be for your application. So, here is some basic information to help you out.

Applies to BOTH AGGRAND 4-3-3 Fertilizers

Generally, any FERTILIZER application rates that you find mentioned on this page or within any of the linked to documents below are perfectly appropriate for BOTH of our 4-3-3 fertilizer products. AGGRAND offers both a “certified” organic product as well as an UNcertified organic product. Application rates listed for AGGRAND 4-3-3 fertilizer will work just fine regardless of which product you are using.

Why do we have both? Why not just offer the certified organic product?

Because, in order to get it certified, we had to slightly “dumb down” the formula. OMRI would not certify our standard organic 4-3-3 product primarily because the blend was “too complicated”. They wanted it simplified. Also, they did not want us to use phosphoric acid in the product, even though it is completely natural.

So, in the new “Organic Series” product (which IS certified through OMRI), some of the lesser ingredients have been removed and the phosphoric acid has been replaced with citric acid.

Thus, if you need a certified product, you can use the “Organic Series” product, which is still very effective. But, if you do NOT need a certified organic product, even though you’d still like to work with a completely natural product, I’d suggest using our standard 4-3-3 fertilizer (product code NOF) which may prove to be slightly more effective than the new “Organic Series product.

Important Notes for Those Using a Tank Sprayer

It is VERY important that you understand that the AGGRAND products can be run through virtually any type of sprayer. HOWEVER, it is HIGHLY recommended that you run the product through 100 mesh filter screen or equivalent if you are using a tank based sprayer of any kind (small or large).

This will make absolutely certain that there will be no organic particulates within the product that will clog pump/filter screens or nozzles when you go to apply. Simply run the product through a filter screen as it is introduced to the spray tank. As long as this is done, you will have no troubles applying the AGGRAND product through virtually any tank sprayer. If you do not filter the product, it is very possible to clog filter screens.

The particulate that is filtered out is still valuable as fertilizer. Throw it on any lawn/garden/crop area. You just can’t pass it very well through spray tank filter screens.

Is is also HIGHLY recommended that your tank sprayer have good agitation, either mechanical or jet agitation, to keep the product mixed well, especially if you intend on using the liquid lime product, as it can easily settle if not continuously agitated.

SOMETIMES, if you don’t have agitation, you can get away with some ball bearings in the bottom of your tank (which move as the tank moves to stir up any settling), but this is unlikely to be sufficient if you are using the liquid lime as well. If you don’t have agitation, running one of your jets to the bottom of the tank can be effective. However, this, obviously, reduces your spray coverage which will lengthen your time on the field.

General Fertilizer Mix Ratio

  • Apply 3 oz / gallon water every 4-6 weeks (heavier at bud set to extend bloom life and enhance flower color)

Fruit Trees

  • Apply 3 oz / gallon water to foliage
  • Apply at blossom and every 30 days during growing season and once after harvest

Trees & Shrubs

  • Apply 5 oz / gallon to foliage in spring until leaves are thoroughly wetted

Lawns & Turf

The following app rates/schedules are based upon an AVERAGE soil profile with minimal previous chemical fertilizer application. See, below for more details on how these rates might need to be adjusted depending upon your soil conditions.

  • Apply 1 qt / 5-6000 square feet every 4 – 8 weeks to Fescue
  • Apply 1 qt / 4000 square feet every 4 – 8 weeks to Perennial Rye
  • Apply 1 qt / 3000 square feet every 4 – 8 weeks to Bluegrass
  • Apply 1 qt / 2 to 3000 square feet every 4 – 8 weeks to Bahai, Bermuda, St. Augustine

The product should be mixed at 3-4 ounces per gallon of water or approximately 1 gallon of fertilizer to 30-40 gallons of water. If you would like to apply the same mix to turf AND landscaping, stick to 3 ounces per gallon (1 gallon of fertilizer per 40 gallons of water)

Hay, Meadows, Pasture

The following app rates/schedules are based upon an AVERAGE soil profile with minimal previous chemical fertilizer application. See, below for more details on how these rates might need to be adjusted depending upon your soil conditions.

  • Apply 1 gallon 4-3-3 and 1 gallon liquid lime per acre

If your soil is exceedingly BASIC (high pH) already, don’t apply the lime. Otherwise, the lime will be very beneficial to good growth as well as to minimize/eliminate the number of calcium lick blocks that are necessary for livestock feeding on this grass/hay.

Important Notes:

Sandy soils should get a lighter application more frequently. More clay-like soils should also get a lighter application more frequently.

If you have REALLY good soil, you may likely be able to get away with considerably fewer applications than listed above. However, don’t just assume you have “good” soil. Most people do not. Unless you’ve been organically maintaining lawn for a considerable period of time and/or have spread compost, etc. your soil probably isn’t as good as you might think it is. However, that being said, we do have customers who really do have great soil and only apply our product once or twice a season as a booster.

Rates are given for lawns with clippings returned to them and which HAVE NOT had extended periods of chemical applications previous to the AGGRAND applications. If high nitrogen chemical fertilizer has been used for more than a year prior to the AGGRAND applications, consider doubling the AGGRAND dose for the first season, to supplement with additional nitrogen (or use our standard dosing with a SMALL amount of liquid ammonia for nitrogen).

Highly “chemicalized” lawns are generally “addicted” to high nitrogen levels and will go into “withdrawl” if that nitrogen is taken away too quickly. So, they need the nitrogen supplement while the soil is built up with the organic micronutrients. After the first season you can probably begin to scale back on the nitrogen until you finally end up back at a standard dosage for the AGGRAND products.

Just for clarity, basically all truly organic products are low nitrogen and would require the same procedure to maintain a good looking lawn.

The longer you apply AGGRAND products, the less you’ll need and less often you’ll have to apply. As the soil profile is enhanced and the health of the grass is enhanced, less and less fertilizer will be needed to keep the lawn looking good. In addition, less and less water will be needed as the stress resistance of the plant is improved and the roots grow deeper into the soil.

Shake all bottles well before using.

Once AGGRAND products have been mixed with water, they should be used within 48 hours. The introduction of water stimulates the microbial activity in the product. Without soil to grow in, the microbes will die out and the result will be that you’ll simply gum up your spray equipment if the mix is not sprayed within a couple of days of mixing.

How to Apply AGGRAND Products

Applying AGGRAND products is very easy and can be done in a number of ways. First, you can purchase a hose end sprayer from AGGRAND (Altrum). These only cost about a buck, and work fairly well in most cases. However, understand that, because they only cost a buck, they’re nothing all that special. It’s not all that difficult to break them, so care should be taken. I recommend purchasing 3 or 4 of them. That way, if you do happen to break one, you won’t be stuck in the middle of an application with no way to apply the rest.

To use the hose end sprayer from AGGRAND, you will attach it to the end of your hose, and then screw on a QUART bottle of AGGRAND fertilizer. Any bottle other than an AGGRAND QUART SIZE bottle will likely NOT work. When you are using this sprayer, you’ll know if the fertilizer is coming through because the spray stream should be brownish in color. If it is clear, you’re not getting any fertilizer.

If you’re not getting any fertilizer through the sprayer, there are a couple simple steps that you can take to rectify the problem.

  1. Filter the AGGRAND product into another container and then back into the bottle. Sometimes, even though the product is filtered through a fine mesh at bottling, some agglomeration can occur as the product sits on the shelf. It doesn’t harm the effectiveness of the product, but can make it difficult to spray if not filtered out.Just pour the product through some cheesecloth, a fine mesh seive or a pair of old pantyhose.If using pantyhose, I’d wrap them loosely around the opening of the bottle forming a sort of “nipple”. Then, when you’re done pouring the product, you can simply “wring out” any excess liquid in the nipple and then take the remaining particulate and throw it out on your garden or flower bed.
  2. If you think filtering may not be quite enough, then you could dilute the AGGRAND product half and half with water in the spray bottle to thin it out.

If you’d like to use a different application method, the following will also work.

Using an Ortho or Miracle Grow Sprayer

First, filter the fertilizer as directed in the above section. Then, mix the filtered fertilizer, half water to half fertilizer in the Ortho / Miracle Grow sprayer “tank”. With these sprayers, this is really a necessity, whereas it is not always with the AGGRAND hose end sprayer.

On my Ortho Sprayer I set the output rate (on the dial) to the 5 or 6 ounce per gallon setting. This will apply the fertilizer at 2.5 to 3 ounces per gallon (because it is already mixed with half water) which is the universal rate for AGGRAND fertilizer application.

Just don’t stand in one spot for very long. You only need a light application at this rate. It comes through pretty quick. This is especially true on flowers and such which are a little more delicate and respond more drastically to minor changes in fertilization. A little too much on the lawn won’t hurt anything, but too much on flowers can burn them. Just give them a light application. Better to be a light application that has to be done a little more frequently on flowers than too heavy an application which might stunt them.

A Little “Trick” I Learned Recently

As with the Ortho/Miracle Grow Sprayer methods discussed above, depending upon your water pressure, you may have dilute or filter the AGGRAND product, even to apply it through our own sprayer. Obviously, this isn’t always the case, but it CAN Be.

So, if you need to, here’s a trick to save you a little hassle.

Get yourself a 2 liter pop bottle and a funnel. Pour the contents of the quart size AGGRAND fertilizer bottle into the 2-liter. Although it probably won’t be necessary, you could even wrap a little piece of panty hose around the opening of the AGGRAND fertilizer bottle and THEN pour it through the funnel into the 2-liter bottle, thereby effectively filtering out ANY larger particulates (of which there generally won’t be much, if any). Add a half to a full quart of water and mix it up in the 2-liter bottle.

Then, affix the spray nozzle that came with the AGGRAND quart bottle to the 2-liter (withOUT the suction straw), attach to the hose and turn on your water. Then, when you want to start spraying fertilizer, simply flip the “switch” on the sprayer to start the water flow and then flip the 2-liter over so that it’s upside-down.

Instead of having to “suck” the fertilizer up through the little suction straw, now gravity will quickly feed the product through the small orifice in the spray nozzle directly into the water stream. As long as the stream is colored slightly brown, fertilizer is moving. If not, something has clogged the orifice (but, if you filtered the product as you poured it into the 2-liter bottle and diluted with water, this would be HIGHLY unlikely).

Tow Behind Sprayers

Be sure to filter the product as directed above. Mix in your tank at about a 1:30 or 1:40 ratio (for turf and hay/pasture applications, you can go as low as 1:15 or 1:20 to minimize the number of trips onto the field, but more water would be better). So, for instance, if you’ve got a 40 gallon tank, put in 1 gallon of our 4-3-3 fertilizer and 39 gallons of water.

It is best if your tank has some sort of agitation, although smaller tow-behind sprayers generally get “sloshed around” quite a bit just being pulled over the lawn or field. So, agitation won’t be as much of an issue with smaller spray tanks (unless you’re applying the liquid lime or liquid bonemeal, which likely will STILL require agitation as they are very heavy, very finely ground and settle extremely quickly without constant agitation).

With larger tanks, you’ll need to have either mechanical agitation or jet agitation (even if you just run one of your spray jets back into the bottom of the tank to agitate things (you can purchase a kit for that and some tank sprayers have similar capability already built-in that you can turn on or off at will).

In a non-stationary tank (such as a large tow-behind), you could even try just simply pouring a bag of ball bearings or something similar in the bottom of the tank. As the tank moves, the ball bearings will roll around, mixing things up (note that this may not be sufficient for the lime or bonemeal, for the reasons already stated above).

Cleaning Your Spray Equipment

As with most organic products, if you do not clean out your spray equipment after spraying AGGRAND, you’ll gum up the works. Once water is added to our product, the pH of the final mix is near neutral. In this environment, the microbes in our product begin reproducing VERY rapidly (we keep the pH of our concentrate low so as to keep them in check). As a result, the “mix” will begin to “gel” within 24 – 48 hours. Obviously, that’s not good for the spray tank.

So, be sure to USE the spray mix within 24 hours AND make sure to run at least a few gallons of clean water through the entire system to clean out all your pumps, lines and jets and make sure that the interior of your spray tanks is cleaned out as well.

Mixing Multiple AGGRAND Products

Multiple AGGRAND products can be applied at the same time. In fact, if you are planning on using multiple AGGRAND products, I recommend that they be applied in the same mix. Otherwise, if not, at least make sure that you space the applications a few days to a week apart. The reason is simple. If you apply our 4-3-3 fertilizer and then go back a half hour later with a lime application, your lime application will “wash off” the 4-3-3 application.

Since AGGRAND works really well as a foliar application (to the leaves), if you wash it off the leaves, you lose that benefit. It will still fortify the soil and the plant will still benefit, but you won’t see the immediate results as you do with a foliar application.

So, try to either space your applications by a few days to a week, or apply them all together in the same mix. Generally, the 4-3-3 fertilizer is mixed at about 3 – 4 ounces per gallon of water. I’d recommend using the same mix for the 0-12-0 liquid bonemeal and the liquid lime (if you need lime). The 0-0-8 kelp and sulfate of potash, I’d use more like 1/2 to 1 ounce per gallon of water, if you’re applying it along with the 4-3-3. It’s pretty powerful stuff. A little goes a long way.

Some Examples of How to Mix/Apply AGGRAND

So, for instance, if you were planning on applying our 4-3-3, 0-12-0 and 0-0-8 from a 40 gallon tow behind sprayer, you might put 1 gallon 4-3-3, 1 gallon 0-12-0 and about 1/4 of a gallon of the 0-0-8 and then fill the rest with water. Then mix it up well.

Alternatively, let’s say you wanted to apply the 4-3-3, 0-0-8 and liquid lime from an Ortho sprayer. You can only put about 16 ounces of total AGGRAND product in the sprayer (at the most) along with about 16 ounces of water. So, for example, for turf, you might want 1/2 as much lime as 4-3-3 fertilizer and then a 1/4 as much of the 0-0-8. So, you’d probably do something like 8 ounces 4-3-3, 4 ounces of liquid lime and then 2 ounces of 0-0-8. That makes a total of 14 ounces of “fertilizer mix” which is just fine – it’s not an exact science – there’s quite a bit of “fudge room”. Then, fill the rest of the sprayer with water (which would be approximately 16-18 ounces of water) and set your dial up to the 8 ounce per gallon setting.

Now, if you are crystal clear on the above on the first read through, then you may have noticed that, at an 8 ounce per gallon setting, with the mix you’ve got in the tank, you’re actually only going to get about 2 ounces of 4-3-3, 1 ounce of liquid lime and .5 ounces of the 0-0-8 per gallon of water in the final spray. Since or recommended mix rate is normally about 3 ounces per gallon, that’s a little low. However, don’t worry about it. It will still work. You just end up putting out a little more water than you would normally need, which is perfectly fine.

Just make sure that, in the end, you put out the correct TOTAL AMOUNT of each product for the area you’re fertilizing. So, for instance, since we’re talking turfgrass here, if it was a fescue lawn, you need about 1 quart (32 ounces) of 4-3-3 fertilizer per 6,000 square feet. You’ve got about 8 ounces of 4-3-3 in your Ortho sprayer, which is 1/4 of a quart, so it should cover 1/4 the square footage – about 1,500 square feet.

Thus, when the mix in your Ortho sprayer “runs dry”, you should have covered about 1,500 square feet. If you’ve covered less than that, on your next tank, walk a bit faster. If you covered more than that, on your next tank, walk a bit slower. You get the idea.

The biggest thing is, just know that it’s pretty monkey proof. You’re not going to severely mess anything up. If you get a little less or a little more than you wanted on a particular area, it won’t be a big deal. Don’t sweat it. Just try to be more accurate on your next tank.

Using Other Sprayers

Other types of sprayers can be used for AGGRAND products as well. As long as the sprayer has good agitation and pressure, just about any sprayer will do. Backpack sprayers, sprayers on pull behind trailers and on truck beds, etc. Any of these are fine for applying AGGRAND. Just make sure to clean any filter screens fairly often as organic fertilizers can begin to clog these over time if not cared for properly.
