If the soil test lime recommendation for a field is 3 tons per acre, and you have pelletized lime with an ENP of 2000 (which is what most pelletized materialsĪpproach ) you would need 3 tons of pelletized lime per acre to achieve the desired neutralization. Higher ENP means that it will take fewer pounds of pelletized lime than ag lime to neutralize the same amount of soil acidity. Pelletized lime is typically finer than ag-lime, so its ENP value may be higher. Lime recommendations can be found in an OSU Extension Factsheet titled "Soil Acidity and Liming for Agronomic Production" (< Most ag lime averages 25 mesh which makes it 5 times coarser than SuperCal 98G and 1/5 as effective. Because 100 mesh has a surface area almost twice that of 60 mesh it should get a rating of 200% on the ENP scale. Since lime is not very soluble the finer its ground the more effective it is. ENP does not give more value for a finer grind of lime. The ENP of a given liming material is a function of three things - total neutralizing power (TNP-depends upon purity of the source and the ratio of calcium to magnesium ), fineness (size of the particles ), and moisture content. Ohio uses a term - effective neutralizing power (ENP ) - to compare the strength of different liming materials. This customer's father applied 2 tons of lime to his farms and there was no pH adjustment a year later. Last year when applying 98G to a grid sampled field we changed the pH 1 point (not 0.1 but 1.0 whole point ) in one growing season. In trials we have seen adjustments to the soil in as little a 2 weeks. SuperCal 98G pelletized lime does change the pH of soils faster and more effectively than ag lime. It is an effective lime source because it is very fine material as well as easy to handle and apply using broadcast fertilizer spreaders however, it simply cannot neutralize soil acidity any better (or faster ) than conventional ag lime materials. It is not that pelletized lime is a poor lime source. This question comes up every year - can I put down a lower rate of pelletized lime and achieve the same result as typical ag-lime at a higher rate? Perhaps, but using a fraction of the recommended rate (say a fourth or a third ) will likely not achieve the desired result. Here's my response to their effort to disprove pelletized lime.Ī ) Pelletized Lime, Can I Get Away with Lower Rates? - R.
