Soil Improvement

Soil improvement Joe's Root-Gyp diagramThe texture of soil is a mix of sand, silt and clay. When combined with organic matter and other natural particles the larger all-important soil structural blocks are formed. Soil is made up of a number of different ‘building’ blocks which are described according to their shape and size using fairly easily defined terms such as light sandy, medium loam and clay. Still with us? Good... While there is little gardeners can do to modify the soil texture, we can influence the way the soil is structured. This can be seen as the plumbing system for the soil which controls water and air flow. It provides space and a protected home for roots and germinating seeds.

So how can we alter soil structure?
The easy to understand explanation:

Calcium is the major element in any type of plant. Low Calcium levels in any growing environment is very restrictive to plant development for all sorts of reasons. Calcium/Magnesium ratios are also hugely important and often when soils are 'tight or sticky' it is because Magnesium levels are too high, especially when the soil has a high percentage of clay.

Without getting too technical Joe’s Root-Gyp helps to disperse some of the Magnesium and replace it with Calcium. This in turn makes the soil more friable (read easily crumbled) allowing oxygen to get to the root zone therefore making the plant far more capable of taking up other nutrients. The other advantage is, because the soil is more friable drainage is far more efficient.

To summarise, what our Gypsum based treatment will do is:

“Improve your soil structure and help to decrease compaction levels, providing optimum air and water availability for grass root growth.”

We currently use Gypsum for the break down of heavy clay soils but it is also extremely beneficial for the grass plant health, especially around salt affected areas such as the seaside. Ask us if your lawn could benefit.

Feeling brave? Here’s the technical explanation:

Cation exchange is the nutrient holding capacity of the soil, So the higher this is the more beneficial nutrients are available to the grass plant. Gypsum as a source of calcium to deflocculate soils is most effective when sodium is occupying the vast majority of the cation exchange sites. This is usually called a Sodic Soil and is often encountered in salt-affected sites close to the sea or where the irrigation contains high sodium. In addition, applying calcium in the form of gypsum to heavy clay soils helps to deflocculate them and therefore facilitate better drainage.
