The liquid manure refills the nutrient storage of the soil. The lime enables the soil to retain these nutrients and release them back to the plants.
It is undisputed that without lime no optimal soil structure can be achieved. As a result, no effective nutrient binding takes place and therefore many important components of the liquid manure cannot be optimally made available to the plants.
The consequence is that the prescribed application values of the liquid manure have too little effect. The new fertiliser ordinance in particular means that farmers are well advised to keep their soil structure under control.
Despite the new fertiliser regulation, the farmer must increase the benefits of the liquid manure as much as possible. To ensure that the soil is evenly supplied with the optimum nutrients, lime should be applied as required.
But what makes liming so important? Among other things, the soil acidifies due to the formation of carbonic acid from the decomposition of organic substances, the removal of calcium and, in some cases, increased amounts of sulphur and nitrogen. A direct consequence is lime leaching. The application of lime counteracts soil acidification.
Optimal soil structure:
Good yield performance and assured soil fertility are the result of careful observation of the relationship between soil volume and pores, the pH value and the results of soil samples. If only because of the emerging climate changes and weather extremes, the soil must be able to bind water and nutrients in sufficient quantities.
Effective nutrient binding:
If you keep the various factors in mind, you can adapt the soil to the new challenges by applying lime.
Counteract the minor effect:
Fast-acting lime is good at what it does, but does not help the soil in the long term. That is why it is necessary to build up the soil with a reasonable supply of lime. After a pH-value analysis the application should be well planned. It does not help to apply a lot of lime at once. Experience has shown that it can make sense to apply the necessary amount in two passes over the year.
In this way you also achieve that your soil can optimally absorb nutrients from the liquid manure.
