Liquid Fertilizer

Post by datcope » Mon Mar 04, 2019 6:43 pm

While waiting to get my soil test back from TAMU, I thought I would get knowledgable on liquid fertilizers. You guys/gals have helped me get a handle on my pre/post-e which I get in granular form and will mix with water (oz/gal/M). Will I do the same with my fertilizer or would it be better to start with a liquid fertilizer like this...

Image

....which I think is recommending two applications/year at 5oz/gal/M.

Liquids enable you to really customize the application. I would not know what you need without seeing the soil test results.
While Iron and the many forms of liquid Iron products on the market are generally harmless when used according to label directions, it is best to apply what the grass actually needs.

Are you using the liquid iron label as an example or do you plan to use it? You can get some Feature 6-0-0 for probably a fraction of the cost of the stuff you posted, Just FYI ;D

@Mightyquinn I was just using that label as an example. Knowing that I have options like Feature will make waiting on the soil testing go by quicker.

@Greendoc @Mightyquinn I was having this discussion over on the 'Soil Testing' section and thought I might update this thread with hopes that you will weigh in on my plan. I got my soil test results from TAMU....

Image

Acknowledging that the recommended dosages of 0.6lbs N/M, 2.7lbs P/M and 0.6lbs K/M are for a 12 month cycle, my plan is to knock out the N and P by applying the following MAP fertilizer...

Image

....in three monthly applications of 0.2lbs N/M and 0.9lb P/M. If I use 1.5lbs/gallon/M of the MAP 12-61-0, that will result in 0.18lbs N/M and 0.9lbs P/M.

Thoughts?

You might want to reduce your P application rates and apply a lot more often. @Ridgerunner and I were talking about your situation. Loading the soil with P might not work for you. Foliar feeding with lower rates may work better. I use as little as 0.2 lb of P/M and plan on applying every 14 days.

@Greendoc I appreciate you guys tweaking of the plan. I could cut it back to 0.75lbs MAP/gallon/M and apply it over 6 applications 2-3 weeks apart. That way each application will be putting down 0.45lbs P/M and 0.1lbs N/M. Do you have a recommendation on what product to use to address my P?

Solution grade MAP from whoever will sell it to you. Brand is not relevant.

Typo, I meant to type ‘K’ (I am getting my N and P from the MAP I ordered on Amazon.

You are going to need more N than what the MAP supplies. I suggest !3-0-45. Potassium Nitrate. Very soluble and compatible with the MAP.

@Mightyquinn

Am I reading the label of Feature 6-0-0 correctly in that you only mix 2oz/gal/M? Does that only give you 6% of 2oz (.12oz or .0075lb) of N per 1000, or is the fact that you are mixing a concentrate with water giving you more N?

Being somewhat new to this, I can easily get behind the numbers of granular but not sure about liquids yet.

@Greendoc I was wondering about the amount of N, but the soil test results recommend only 0.6lb N/M for the remainder over the next 12 months. Am I reading that correctly? Also, I understand where the 13-0-45 Potassium Nitrate will help with my N and K, but the question is...where do I find it?

Feature is more of a supplement as it has most of the micronutrients your lawn needs. The Nitrogen in Feature is just there as a booster for the Iron mainly. It would be very cost prohibitive plus you would be over applying all the micro's if you tried to feed your lawn just on Feature alone.

I am looking at using this to supplement the the MAP I am putting down....

Image

Can I mix it with the MAP or should I do separate applications?

No urea on alkaline soils. does not work
Ammonium sulfate is preferred

As for your N requirement how long is your growing season. I try for 0.25.-05 lb of N per month of growing season

Thanks @Greendoc for the guidance. If I were to guess, I'm thinking the growing season is 6 months (April-September). Putting down 0.5lb N/M/month sounds like a good starting point.

As to the Ammonium Sulfate, where do you find it?

Same places you are finding the MAP . Here is a place I send consumers for solution grade stuff. I am spoiled in that the same Nutrien branch I get my FEAture from has all of my solution grade stuff as well.https://customhydronutrients.com/index. ... age=index

Tomorrow I start my foliar application of N and P per the recommended doses listed in my soil test results...

Image

For the P, my plan is to put down six bi-monthly doses of .75lbs MAP/gallon/M resulting in 0.45lbs P/M and 0.1lbs N/M. per dose.

Image

For the N, I plan to put down monthly doses of 2.4 lbs Ammonium Sulfate/gallon/M resulting in 0.5lbs N/M per dose.

Image

Thanks again to everyone who offered up advice.
