What are the best nutrients for a lawn?
seventeen essential nutrients that a plant needs to grow, and most of them are
extracted from the soil through the roots. In fact, there are only three
nutrients that plants acquire from elsewhere, namely carbon, hydrogen, and
oxygen. The plants get these three from water and air but must get all the
other nutrients from the soil.
Soil Micronutrients and Macronutrients
The other fourteen essential nutrients are split into two groups, soil-derived macronutrients, and soil-derived micronutrients. They are so named according to how much of each a plant needs, thus they need far more macronutrients than they do micronutrients.
The six soil-derived macronutrients are nitrogen, phosphorus, potassium, sulphur, calcium, and magnesium. The eight soil-derived micronutrients are boron, chlorine,
copper, iron, manganese, molybdenum, nickel, and zinc.
How Soil pH Affects Nutrients
Soil pH values are a measure of the acidity or alkalinity of soil. The pH scale runs from 0 to 14 and the more acidic the soil, the lower the pH value will be, while the more alkaline it is the higher the value will be. The middle mark of pH 7 acts as the neutral point.
The soil’s pH value can have a significant effect on the solubility of essential nutrients and minerals. This is important because the nutrients can only be absorbed by plants after they have been dissolved in the topsoil, with most minerals and nutrients being more soluble in acidic soils than in neutral or slightly alkaline soils. This is not the case for all plants, and there are plenty that fair better in more alkaline soils.
Plant growth is heavily influenced by the soil pH. Very strong acidic soil, for example, prevents bacteria from properly decomposing organic matter which results in an accumulation of said organic matter that continues to compete with the plants for the essential nutrients, especially nitrogen which is a very important nutrient for lawns.
Essential Lawn Nutrients
While lawns still require the full set of essential nutrients, there is one that is significantly more important than the others. Nitrogen is what makes lawns look lush as it is the key nutrient that instigates green and leafy growth.
Other important lawn nutrients such as phosphorus and potassium are usually in plentiful supply in a healthy lawn. However, nitrogen levels can rise and fall as it can be moved through the soil via rain or watering.
The best way to ensure your lawn is getting all the nutrients it needs is with a soil improving fertiliser or by growing the lawn on a high-quality topsoil layer. There are also plenty of excellent garden composts you can mix in to give the soil a healthy boost of all the essential nutrients it needs.
