Who Sells Lawn Fertilizer In Sriracha Area?

[mymonkeyhusb]

Does anyone know where lawn fertilizer is sold in the Bang Phra/Sriracha area? I have a lawn that needs a good lawn fertilizer but don't know where to go to buy. A local tree seller wanted to sell me 3 kg of ammonium nitrate for 600 baht but I didn't know if that is a good price or not. I am used to buying heavy sacks of Scotts lawn fertilizer back in the old country but I don't see that option here.

Thanks!

The stuff I use is in a blue bag with a rabbit logo. Big letters 46-0-0. Bought at a nursery around 30 kilos, 500 baht, feed twice a year, works good.

Guys,

Why do you want to use urea on a lawn? If it is a must then mark out the lawn in a grid and simply go urinate on it all in sequence. Same numbers 46-0-0. Why dont you look at getting your sandy soil healthy and then worry about the greenest of the lawn?

Yes there are people who can supply to your door. PM me if your interested.

Sorry forgot to mention, if you must use urea, go to the local feed store and buy a 50 kg sack. I pay 570 baht here in Sisaket.

The tree seller is trying to stiff you. Some shops do sell NPK by the kilo and Urea (46-0-0) is about 15 Baht per kilo bag.

To echo what IssanAussie says, Urea will give you a short term pop, but will hasten the longer term deterioration of your lawn.

Better to mix up compost, sand (or fine coire) and burnt rice skin, in thirds (all available anywhere) and fork it in at 1 kilo per square metre. Forking in entails making holes with a garden fork and sweeping in the mixture. 2 or 3 applications and regular cutting will give you something Augusta would be proud of.

I've never seen bags of dedicated lawn fertiliser for sale in Thailand, but maybe if you have a local golf club you could have a word with the greenkeeping staff.

Buying the full 50 kg bag will be cheapest.

The price of Urea 46-0-0 varies a bit throughout the year

between B600 and B750

Farm season is heading into idle now,

so the price should be low.

Although the world market for Urea is generally rising.

Letting someone else open the big bag and

weigh it out into retail size packages

is simultaneously convenient and expensive,

depending on how much you need.

The man offering 3 kg for B600 saw you coming.

He could offer you 30 kg and still make decent money.

If you keep it cool and dry it will not deteriorate

If exposed to humidity it will attract water until it runs out the bottom as liquid.

It is a strong desiccant.

Keep in mind that 46-0-0 is very hot...easy to burn your grass dead.

Scatter it very sparsely, water it like mad, wait a week,

look for the spots that didn't green up as green as others,

and apply a bit more there.

Scattering Urea too heavy is a good recipe for big bald patches.

Ammonium Nitrate 33-0-0 is the same end result, not as hot,

so should be the same ratio in price....46 to 33

If Urea is B700 than Ammonium Nitrate would logically be B500

If your soil is strongly acid,

as most tropical soil is,

you can bring the pH up gently with limestone dust.

It will stabilize at pH 8.3 if you put an excess on,

which grass does well at.

Other plants won't like a pH that high,

so even plain old limestone can be over applied.

It takes time to leach into the root zone,

since you can't plow it into the grass.

If you want faster lime treatment use

Calcium Hydroxide Ca(OH)2 Poon Khao

available at any building supply store

Scatter it very gently however, as it will immediately act

It like the fertilizer is easy to burn the plant with an excess.

It you want to dehumidify a room / closet / drawer / food cabinet,

Mix Urea and Ammonium Nitrate dry granules together

In the weight ratio

44 Urea

56 Ammonium Nitrate

Together they will absorb moisture from the air until they are a dilute wet solution

Haven't been able to find the vapor pressure diagram to know exactly how much water it will absorb,

but it's a lot.

At 30% Water Weight the Vapor Pressure is still negligible,

which means it has a lot more water to take up.

If you sprinkle the dry mix across the bottom of a tray,

the tray will quickly fill up with water.

After it stops absorbing water in the house, then spray it on the lawn.

So that's why I had those brown spots. I thought it was the dog.

If you use urea don't use much. We first used it after a long dry spell. Ran around the lawn at midnight in the torrential rain throwing it around like confetti, thinking the rain would disperse it. Oh ho! as Thais say, Several days later the lawn developed serious skin cancer - brown spots everywhere. Took months to recover. We now put up with the weeds and let FIL's chooks in every now and again.
