Dispelling the myths of spreading agri lime

Dispelling the myths of spreading agri lime

Over the last two decades, the spreading of agricultural lime has decreased dramatically; less than half the average from the 1980’s. As a result of this, Teagasc have said following research, that on average, 65% of all soils have a lime deficiency. So why has lime spreading dwindled?

The benefits of lime use include:

  • Increased yields
  • Better grass species and clover survival
  • More microbial activity
  • More nutrient uptake by grass

Regaining value from the land

Further more, from having an incorrect pH in the soil will result in the value of fertiliser being lost on the land. In order to get your pH right and get value from your land, soil samples need to be taken every 3-5 years and following the results, corrective action must be taken. Contrary to common beliefs, lime can be applied at any time of the year, with mid-summer and autumn being the most ideal times.

The most cost-effective form of lime is ground limestone, which will begin to work almost immediately. Once it has been washed into the soil, adjusting the pH of the soil in the first three months. The maintenance of the pH levels follow in the next 12-36 months.

Calculating ROI

Similar to any other business, ensuring that there will be a return on investment is of great importance. Once the pH of the soil is optimised, the output of the grass can be increased by 1tDM/ha according to Teagasc.
