Here's my response to their effort to disprove pelletized lime.Ī ) Pelletized Lime, Can I Get Away with Lower Rates? - R. Network C.O.R.N Newsletter 2009-09 April 14, 2009- April 21, 2009, published by Ohio State. $12 will buy a ton a bit at the quarry, Acid soil really responds to lime. Might be the best money you spend all year, might not. Posted 06:57 (#684333 - in reply to #684315) Subject: Re: Pelletized LimeĢ00 lbs is $12 spread here. Will I get any response by using pelletized lime for this years corn and soybeans. Wanted to spread beat lime this winter but conditions didn't allow, to much snow. Posted 06:04 (#684315) Subject: Pelletized Lime Influence of source and particle size on agricultural limestone efficiency at increasing soil pH. 98G is 36% calcium and less than 0.5% magnesium. The higher the magnesium content in a liming material, the slower it corrects pH and the more material you need to make that correction. Dolomitic aglime means it contains more than 5% magnesium. The color of a liming material does not indicate its chemical composition. MYTH #5: Light colored or white aglime means it is “hi-cal” lime requiring a larger investment in aglime every five years. Using lower rates to maintain soil pH results in a smaller annual investment vs. After soil pH is corrected, we recommend an annual or biennial maintenance rate of 98G (200-300 lbs/acre) be included in the dry fertilizer mix to offset acidity created by nitrogen fertilizer. Generally, 98G’s application rate for correcting soil pH is considerably lower than aglime, reducing the per acre application cost. A better cost comparison is to evaluate pH correction on a per acre basis and in a variable rate application scenario. When comparing 98G to aglime on a per ton basis, 98G can look like an expensive option. MYTH #4: 98G pelletized limestone is too expensive In order to maximize yield potential every year, soil pH should be maintained at a consistent level. This pH roller coaster is depicted in the line graph above and is not a long-term solution. After the third year, soil pH drops below optimal levels and yield suffers again. While soil pH slowly returns to optimal levels in the first one to two years, yield suffers. MYTH #3: Aglime will work better long-termĪglime takes about two years to correct soil pH. Many pell-limes are manufactured from dolomitic limestone and are slow to react just like their parent material. 98G is made from 98% pure calcium carbonate limestone and is ground to an ultra-fine powder before it is pelletized, maximizing its reactivity. Pell-limes vary widely in raw material and manufacturing quality. Pell-lime is a nickname used to refer to pelletized limestone. However, research completed at Iowa State University in 2018 showed 98G resulted in more rapid and sustained pH correction than calcitic and dolomitic aglimes.* It is true that 98G works quickly, changing soil pH more rapidly than aglime. When it comes to increasing soil pH, some agronomists and growers view pell-lime as a quick fix, often used on rented acres, while aglime is used as the long-term solution.
