    I have a few lawns that I would like to use liquid fertilizer on. I have a subdivision that is mostly a clay hard pan base 3-4 inches under the grass. most of the granule will wash away with a heavy rain so I thought I could use liquid instead. I am not a CPO, so can I legally spray just fert. I haven't been able to find anything that says yes or no.

    You sure can according to the laws on pesticides. However, will this run afoul of the fertilizer regulations that mandate a starved lawn? I cannot imagine using only slow release urea as the N source. I hate that stuff. Not to mention, it is not slow release when the heat and humidity makes the granule dump all of its N all at once.

    The only thing you can do is put down granular fertilzer and that is it. If I am correct they are even trying to change that too.

    As long as you apply only fertility products (no pesticides) I was of the opinion that you sure can make liquid applications.

    I will second this post. There is no restrictions on how fertilizer is applied. only where and when it is applied.

    I use liquid fert in conjunction with granules. My sandy soil has no chemical holding power and by using both forms of fert I can spoon feed with little or no leaching. I use smaller amounts of both product but hopefully timed so it can all be up taken.

    I believe you are confused with the LIMITED PESTICIDE LICENSE application restrictions. A Limited can only use Manuel hand pump applicators and no power applicators.

    Did I miss something? I took the BMP class last November after the ext office said it was required after Jan 2011. Ric is right manual applications only, not even a powered bp. Realistically there is a big equipment outlay for tanks, pumps, hoses, reels and guns. Sounds like your overthinking the washout factor. Let's not forget about the N and P blackouts too. Coming to a county near you soon!

    You might be misunderstanding my post. Manual applications of PESTICIDES only with a Limited Pesticide License.

    BMP has no limitations on the HOW applied only the WHERE & WHEN. That means a power fertilizer spreader or a powder fertilizer sprayer

    The OP may want to check his county restrictions if any also as they may come into play. For example in Orange County there is a restriction in terms of how much N can be applied at one time and if you wish to put up to 1lb of N then over 50% of the N must be slow release. I am not familiar enough nor do I have interest in liquids at this time but most of the ones I have seen are not slow release, many again of the the ones that I have seen also contain P, which could cause a issue with the regulations.

    bmp is not the license, its a requirement to get the license...
