GoldLime

There are several factors that should make you consider Gold Lime. It is totally natural (organic), our Gold Lime is made from fossilised coral and seashells and it contains, not only Calcium and Magnesium, but also important elements like Manganese, Copper, Zinc, Molybdenum and Boron.

Gold Lime is micronised calcium carbonate, a 50/50 blend of the finest NZ lime & a soft golden fossilised coral lime from Australia. This makes it 100% plant available, so fine that plants can uptake through the leaves & the roots.

The benefits of Gold Lime

  • It is quick acting and immediately available to plants
  • Can help lift soil pH and the Base Saturation
  • Boosts clover growth
  • Encourages worm activity and soil microbes
  • Prevents soil compaction
  • Releases locked up nutrients
  • Makes pastures more palatable
  • Gives denser pastures
  • Reduces milk fever and tetany (Grass staggers)
  • Benefits general stock health
  • Improves seed germination
  • Very economical and cost effective

Most importantly Gold Lime can be applied any time of the year and sprayed through a rosette or a boom sprayer.

Why Lime Soil?
The reason for liming soil is to improve the performance of pasture (plants).
Soil acidity affects the plant root environment, which ultimately affects plant growth and performance.

What soil properties are influenced by pH?
Some of the widely accepted adverse effects of low soil pH are:

  • Aluminium (A1) and Hydrogen (H) toxicity to plant roots. These two elements increase in solubility as pH decreases. (Especially below pH of 5.5)
  • Decreased availability of Phosphorus (P) due to formation of insoluble Iron and Aluminium compounds (Lock up).
  • Poor performance of nitrogen fixing bacteria. (Clovers not working effectively)


How do I know how much lime is needed?
It is advisable to complete a soil test, R J Hill Laboratories use the base saturation as a determining factor in the amount of lime needed, they will include this information at no extra cost if requested. The Base Saturation of the Cation Exchange Capacity (CEC) is according to this laboratory a more reliable indicator of lime requirement than the pH. pH can show seasonal variation, R J Hill technical notes.

How do I know if I need lime?
It is not the soil that needs the lime; it is the plants that grow in the soil that can benefit from the liming effect. Liming is needed only when your soil pH is below the recommended range for the plant species you are growing. For grasses-wheat-maize-oats etc – this range is from a pH of 5.5 – 7.0 For legumes such as peas-beans-clover etc - the range is from a pH of 6 – 7

What is Cation Exchange Capacity & Base Saturation?
The cation exchange capacity of a soil is a measurement of its ability to bind or hold exchangeable cations. In other words, it is a measure of the number of negatively charged binding sites to which the exchangeable cations can affix themselves. (Cations are: Potassium, Calcium, Magnesium, Sodium, Hydrogen and Aluminium) Hill Laboratories technical notes. The total base saturation recommended range of the base saturation is 50-85%, with the upper level being the more desirable. A high base saturation figure can reduce leaching of nutrients. There is a strong correlation between Base Saturation and pH.

Can I over-lime?
Over-liming can cause the soil pH to increase beyond the range of optimum plant performance. Reduced plant growth is usually associated with deficiencies of some micro-nutrients such as manganese (Mn), iron (Fe), zinc (Zn) and copper (Cu). These elements become less available if the soil pH increases too much. Over-liming is also costly, as lime and its application need to be paid for.

 

Application Rates / Recommendations

The recommended rate of application is 15-25 litres per hectare. The rate can vary according to soil requirements.
