The importance of maintaining a correct pH is essential for the following reasons

  • It increases the availability of key plant nutrients in the soil
  • To reduce soil acidity, as most crops will not thrive under acidic conditions
  • Encourages soil biology activity, therefore enhancing the organic matter cycle in the soil, often releasing available N
  • It improves the physical condition of the soil by improving soil structure

We here at B & B Agricultural Contractors offer a full service when it comes to improving your soil so that you can improve your crop.
Our team can carry out free testing of your soil to find the pH so that we can then work out how much lime is required. The lime is then delivered using our own lorries ready for us to spread for you.
We use a spreader that has floation tyres to minimze the ground pressusre on the land, it is ground driven rather than PTO driven so that the right amount of lime is spread regardless of the speed the tractor travels at.

WHY USE AGRICULTURAL LIME?

Using Lime to Set Back Time

There are few things as effective as agricultural lime fertilizer when it comes to strengthening your soil. Used properly, it can help to restore your soil to the qualities it had in the past.

Agricultural Lime Fertilizer

When you use lime, you can dramatically reduce the amount of fertilizer required to get the yields you’re after. Agricultural lime helps to stabilize the pH balance of your soil. When you get those levels right, you simply don’t need as much chemical fertilizer so your input costs start falling right away.
Another benefit of lime is that it makes it easier for your plants to access the nutrients in the soil. The less effort they expend on accessing nutrients gives them more energy for growing strong and increasing their yield.

How Does Agricultural Lime Fertilizer Work?

The Agricultural Lime we provide is an all-natural mineral fertilizer. It reduces the acidity of your soil. Soils that are too acidic inhibit plant growth. Some plants simply won’t grow at all in soil that is too acidic. Agricultural Lime corrects soil acidity and pH levels by neutralizing the acids in soil, so that microorganisms can break down the organic material that replenishes the soil.

Additives like calcium and magnesium, found in Agricultural Lime, are required to rebalance the soil’s structure. This also improves water penetration and facilitates the intake of major nutrients such as nitrogen, phosphorus and potassium.

How Often Does Limestone Need to be Applied?

This depends on the farming practice. For conventional farmers who use chemical fertilizers, sprays and grow high efficiency and GMO crops, the soil requires more frequent limestone application. On average every 2 to 3 years.
For organic growers, limestone can be spread less often, as organic farming processes result in a reduced build-up of acidity. Applications can be limited to every 5 to 10 years.

We work closely with you to find the right frequency based on the specific needs of your soil. And if you have questions — any time — we’re there for you.

EFFECTIVE LIMING RECOMMENDATIONS

Arable fields

  • Should be limed to a target pH 6.7, or 7.0 for acid-intolerant crops such as legumes or beets or where club root is a problem.
  • The pH should be corrected in the whole top 20cm of topsoil. Consider timing of lime application with cultivations to get the lime mixed into the active root zone.
  • 8 t/ha (3.2t/ac) of limestone will be needed for every 1.0 unit rise in pH (rise = target pH minus measured pH) on medium soil.
  • Under arable production, typical rate of pH decline on heavy soils is about 0.1 units per year equating to a lime loss of just under 1 t/ha/yr.
  • Granular Lime can be used as a little & often approach and is particularly useful on pH sensitive crops (e.g. sugar beet) or those with acidity issues such as club root.
  • Annual lime application is unnecessary, where the full rate is applied but the topsoil pH should be rechecked with a view to re-liming after 4-5 years.

Grassland

  • pH must not drop below 5.5 (not below 6.0 if legumes like clover are important).
  • Fields should be limed to 6.2 or 6.5 respectively.
  • 6 t/ha (2.4 t/ac) of limestone will be needed for every 1.0 unit rise in pH (rise = target pH minus measured pH) in the top 15cm of soil on medium soil.
  • Lime reaction and lime loss is slower than on cultivated fields but it is still prudent to recheck pH every 4-5 years.
  • Inadequate pH inhibits clovers and earthworms and gives lower calcium uptake resulting in poorer quality forage and worse mineral balance for the feeding animals.
