Different types of lawns have different fertilising needs. For instance, Sir Walter DNA Certified Buffalo lawn needs to be fertilised every three months, while Sir Grange needs fertilising only three times a year. Despite the differences though, this requirement is necessary: fertilising your lawn still remains to be an important part of the creation and maintenance process. Lawns that aren’t fertilised rely on the nutrients that the soil currently has, and unfortunately, the soil in most homes these days are not packed with a lot of nutrients at all.
Lawn grasses need various macronutrients and micronutrients to stay healthy and to perform necessary plant functions. Micronutrients (also called trace elements) include boron, chlorine, copper, iron, manganese, molybdenum, nickel and zinc. Primary macronutrients include nitrogen, phosphorus and potassium. These macronutrients are the typical ingredients of all sold fertilisers, for these are the elements most deficient in soil despite being crucial for plant growth.
Synthetic fertilisers, which often come in liquid or granular form, are the most popularly used of all types of fertilisers. Most liquid fertilisers are reserved for professional companies and often require special equipment to be applied. Granular fertilisers, on the other hand, are easy to apply and need only the basic equipment—a rotary or drop spreader will suffice.
Organic fertilisers are made up of naturally occurring biodegradable materials, such as animal manure, compost, mineral deposit and seaweed. Organic fertilisers help improve soil structure and increase water-holding and nutrient-holding capacity. They don’t cause leaching and don’t kill beneficial microorganisms in the soil.
Dry organic fertilisers are usually made of one material such as kelp or rock phosphate, and they may also be a blend of ingredients. Dry organic fertilisers are usually applied by broadcasting it and then raking it up into the top six inches of the soil.
Liquid organic fertilisers are usually effective for fruit-bearing and flower-bearing plants, and are applied in important periods such as the fruit setting period. Application for leafy crops is recommended on a biweekly basis.
