Yeah 300 lbs is what you need. You can do it anytime you choose to, weather will not have an impact.Jeaux Bleaux said:And is there certain times of the year or temperatures when applied, that would be better to do it? Any risk in 90 degree weather like right now?
Yes. How fast and how much of a return to a lower pH will occur will depend on a number of factors such as: climate/rainfall/irrigation/leaching/soil texture, CEC of the soil and type and amount of N fertilizer applied.kur1j said:@Ridgerunner Is the Ph change only temporary?
Not sure if this is what you are asking, but: With the exception of a peat bog for instance, most undisturbed native mineral soils of the world will have a pH between 4 and 9. This is a result of rainfall/leaching, type of parent material of the soil, and OM decomposition. I would think that if left undisturbed for millennia, these factors would have found an "equilibrium" and pH would remain relatively constant.If nothing else is really done will the Ph change drastically over time?
Clay is great at holding nutrients...for the same reason it is great at holding water, it is negativley charged - water is polar and the cations are + charged, so they stick to clay very easily.kur1j said:@Ridgerunner I've did 2 soil tests last year. One around April/May last year, and then another in late summer (Sept).
The April/May Soil test showed I had pH of 6.42. The one late in the year showed I had a Ph of 5.9. So in a matter of 6 months my Ph. dropped .5 which is the reason I asked how much it can change.
I had a local lawn care company doing my "weed" control (it came with house) and they applied Lime in December. I just sent off another soil sample test today to see where I'm at with things. From my understanding, this clay soil is generally acidic and doesn't hold onto nutrients very well at all. The only positive to it is that it holds moisture really well. Even though I was doing 19-19-19 1lb/1k a month every single test came back low on my P and K. April had a recommendation of .7lbs/1k of P and K (it was a generic recommendation of 3.75lbs of 16-16-16 per 1k). The second soil test I did came back with a recommendation of putting down 1.95lb1/1k P and 1.61lb/1k.
I'm interested to see what this new soil test comes back with. If everything is low...I'm going to up my fertilizer rate. But I digress. I don't want to hijack this post any more than I already did.
This person lied to you.kur1j said:@viva_oldtrafford Interesting. Someome at a local nursery told me the exact opposite. They sent off a soil test for me and when it got back they were explaining why all the nutrients were really low. The tests were showing that I was low 1-2lbs for both P and K. It was showing everything being low except calcium and surfer. I've got a soil test on headed to a lab now so I'll see if anything has changed. But if everything is still really low, would I just need to dump a lot more fertilizer and some micronutrients?
