Both are good, it depends on the use.
Calcium lime has a faster correction effect than magnesium lime.
Magnesium lime supplements an amount of magnesium that is important for photosynthesis functions.
Often the pH level of the soil is underestimated. If this is too low, yields are limited because the nutrients are not available in an optimal manner, so to improve productions it is sometimes sufficient to raise the pH level with a liming treatment.
In un periodo economico come quello che stiamo vivendo, in cui è opportuno calibrare e ottimizzare i propri investimenti, in funzione di ottenere le migliori produzioni, l’utilizzo della calce viene incontro alle esigenze agronomiche e di conseguenza economiche dell’agricoltore.
With a pH level of 5.5, most crops struggle to assimilate nutrients, so a liming treatment is advisable.
In agriculture, the word “lime” is used to identify a number of products that differ from each other.
Real lime is calcium oxide (CaO), produced by firing rocks made of calcium carbonate.
Lime consisting only of calcium oxide is defined as calcium lime. Often in nature, calcium carbonates are combined with magnesium carbonates, therefore, after firing, limes are obtained that have different percentages of magnesium oxide (MgO). Those with the lowest magnesium content are called magnesium limes, those with higher content of magnesium are called dolomitic limes.
Some erroneously use lime to refer to calcium hydrate (Ca(OH)2) which is obtained from the hydration of calcium oxide with water.
With the crop in the field it is advisable not to use calcium oxide but Magnital instead.
Calcium carbonate can correct the pH level of the soil but it takes an extremely long time. Its use is not prohibited but is not optimal for the purpose for which it is employed.
To correct the pH level of the soil faster it is better to use calcium oxide.
In agriculture, powdered lime is better than granular lime because, being a fine powder, it reacts faster and more extensively than when in granular form.
In practice, powdered lime is used less than granular lime due to the spreading method.
A normal fertiliser spreader is sufficient for granular lime but the same appliance cannot be used for powdered lime because, during spreading, too much dust would be produced around the spreading machine.
To raise the pH level of the soil by one point, on average, 1 tonne/ha of lime oxide is sufficient. For more accurate data please use the calculator on our website.
When the crop leaves show several different colours (yellowish) and there are root development problems. All these factors can cause low yields, so it is appropriate to take action to safeguard the production.
Approximately after two weeks, to allow the lime to do its pH adjustment work without damaging the seeds.
After a first “major” liming, it is advisable to continue the following years with maintenance liming that helps to maintain the optimum pH level obtained with the first treatment. Maintenance lime treatments are carried out with lower doses than the first liming.
Yes, you can use less fertilisers; in fact, lime increases the availability of nutrients that would otherwise not be absorbed by crops.
The main purpose of lime is to raise the pH level of the soil. By increasing the pH level, certain characteristics of the soil are improved which leads to better yields.

In an economic period like the one we are experiencing, in which it is necessary to calculate and optimise investments carefully, the use of lime can take care of the farmer’s agronomic and therefore economic needs.
It is advisable to carry out liming after ploughing, to make sure that the corrective action is performed in the area where the root system develops. Lime treatments before ploughing are recommended for in-depth liming, that is, when done for the first time on a strongly acidic soil.
Calcium oxide has a pH corrective effect that is significantly faster than calcium carbonate, so it is preferable to use the former, especially in the presence of strongly acidic soils.
Due to its characteristics, calcium oxide is not allowed in organic farming.
