Soil Analysis and Nutrition
|
BioBase Organic and Biogran fertilisers are formulated around a simple but often misunderstood principle: fine turf does not need nutrients added to the soil, it needs nutrients sufficient for the plant. For croquet lawns in particular, where growth rates are deliberately controlled and rooting depth is shallow, nutritional demand is modest and highly predictable. These products are therefore designed to supply exactly what the grass uses during growth and mowing, rather than attempting to alter soil nutrient reserves. |

Soil Analysis
While Phosphorus and Potassium levels are straightforward to establish, Nitrogen remains difficult to quantify. This is because a significant portion of Nitrogen is locked within organic matter and only becomes detectable through soil testing once it has undergone mineralisation.
Conventional fertiliser programmes are frequently driven by soil analysis, with nutrients applied to raise indices regardless of whether the grass actually requires them. BioBase and Biogran take a different route. Their N-P-K balance mirrors plant uptake, so the nutrients applied are taken up by the grass as growth occurs. Because supply closely matches demand, there is no excess left behind to accumulate, bind to soil particles, or distort soil analysis over time.
Nitrogen
A key part of this approach is the organically based nitrogen used in both products. Unlike soluble synthetic nitrogen, organic nitrogen is not immediately available to the plant. It is released gradually by soil bacteria as they break down the organic material (mineralisation). This matters because bacterial activity increases under exactly the same conditions that favour grass growth: suitable soil temperature, adequate moisture, oxygen availability, and active roots. In effect, nitrogen release is synchronised with plant demand. When the grass is growing and needs nitrogen, bacteria are active and release it. When growth slows, release naturally reduces. This biological timing prevents flushes of soft growth, reduces leaching losses, and ensures that nitrogen is used efficiently rather than accumulating in the soil.
Phosphorous
Phosphorus in BioBase and Biogran is included at a level appropriate for established fine turf, where requirements are very low. Its role is to support root metabolism and energy transfer, not to build soil reserves. By supplying only what the plant uses, these products avoid the gradual phosphorus build-up that is commonly seen where fertilisers are applied to chase soil index targets rather than plant need. Over time, soil phosphorus levels remain stable because uptake and application are in balance.
Potassium
Potassium follows the same principle. It is provided to support cell strength, wear tolerance and stress resistance, particularly important on croquet lawns, but not in quantities designed to raise soil potassium indices. The grass takes up what it needs to maintain performance, with no excess left to accumulate in the soil profile.
Because BioBaes and Biogran work on a nutrient replacement basis and rely on biological release mechanisms, they do not act as soil-modifying fertilisers. Instead, they support consistent turf performance while leaving soil chemistry largely unchanged. This is why the same analysis can be used successfully across a wide range of soil types and soil test results. The grass simply takes what it requires, and nothing more.
Croquet Lawn Nutrition
For croquet lawns, this approach is particularly effective. Controlled growth, tight sward density, predictable pace and minimal disruption are all easier to achieve when nutrition is steady and biologically regulated. By feeding the plant in line with its natural demand, rather than forcing growth through soluble inputs, BioBase and Biogran help maintain performance without the need for aggressive mechanical intervention or repeated corrective treatments.
In simple terms, these products do not attempt to “improve” the soil by adding nutrients it does not need. They replace what the grass removes, at the time it can use it, through the action of soil biology. That is why BioBase and Biogran provide the correct nutrition for fine turf, including croquet lawns, without changing soil analysis.
