the liming material, the quicker it will react with the soil. Oxides and hydroxides are generally marketed as powders while the limestones can vary in their fineness.

a$.$ The fineness of limestone is measured by passing the material through $10$ and $50$mesh sieves.

b$.$ Evaluation of liming materials based on fineness:

Effectiveness $($Relative Neutralizing Value or RNV$)$ of the material is $($:$(1^{**}60)\}.$ If the lime recommendation was for $1$ ton of $100\%CaC{O}_3,$ then it would require $\frac{2000}{72}=2,778lb$ of this other liming material.

$3.$ Now determine the effectiveness of a liming material if $40\%$ passes through a $50-m$ sieve and $96\%$ passes through a $10-m$ sieve. The material has a $CaC{O}_3$ equivalent of $98\%.$ Again, show all of your calculations. $(5pts)$

$4.$ Determine the effectiveness of a liming material if $60\%$ passes through a $50-m$ sieve and $75\%$ passes through a $10-m$ sieve. The material has a $CaC{O}_3$ equivalent of $89\%.$ Again, show all of your calculations. $(5pts)($I$\text{'}$m only looking for the RNV$)$

Limestone fineness and reactivity also play a large role in adjusting soil $pH.$ In general, the finer the liming material, the quicker it will react with the soil. Oxides and hydroxides are generally marketed as powders while the limestones can vary in their fineness.
