3. New Lawn Establishment Photo 3: Perfect place for fun It is necessary to know the important steps of the lawn development techniques. The successful lawn establishment means doing the “right thing at the right time”. 4. Planning Much success depends on how well you plan your lawn development. There should be provision for basic equipments and inputs (Table 1). A turf grass is available in two broad categories, warm season grasses and cool season grasses. Cool season grasses are recommended for warm temperate to sub alpine zones
5. Soil preparation Preparing a field for lawn development is one of the most vital steps and a good seedbed preparation is a prerequisite for successful lawn establishment. If the soil is poor, arrange additional forest topsoil. The topsoil from broadleaved forest is preferred. Topsoil from the blue pine dominated forest can be used but it has acidity problem. On removing debris such as stones, wood and other items from the planting area, add the top soil and the thickness of topsoil should be uniform both on slope and flat areas. It is advisable to test your soil before adding any nutrient to the soil. A soil test eliminates guessing the amount of nutrients to be added. Lawn grass species perform well at soil pH range of 5.5 to 7. For the proper grass growth, if your soil pH is below 5.5 add lime to the soil and if it is above 7, add sulfur. Organic matter and other soil additives such as fertilizers can usually be mixed with the topsoil. Lawn requires a larger amount of inorganic fertilizers mainly Nitrogen, Phosphorus and Potassium (NPK). Lawns require a large amount of N-Nitrogen to promote growth, color and general vigor. P-Phosphorus stimulates early root growth to ensure seedlings develop properly. Freshly seeded lawns require a fertilizer with high phosphorus content. Also P is necessary for proper plant cell division, which results in a strong, healthy and sturdy grass plant. K-Potassium strengthens root structure and increases disease resistance, improving the overall hardiness of grass plants. Even distribution of these materials of soil is most important. Rake the surface and roll the soil with a heavy roller 90-130 kg to define humps and hollows. Then rake surface lightly even off these irregularities and to prepare a loose planting bed of 1/4 -1/2 inch of soil. Photoes 4, 5, & 6: Different stages of land preparation for lawn establishment 6. Seed rate and sowing time Seed rate while sowing depends on what lawn species one chooses and size of seeds. For instance Tall fescue (Festuca arundinacea) is 130kg per acre and whereas Kentucky bluegrass (Poa pratensis) seed rate is 35-40 kg/acre is applied. Lawn can also be sown in mixtures of 2-3 grass types. When a mixture containing seed two or more types of is applied, it has an advantage-the strength of one grass type compensates for the weakness of another. For this reason, a mixture is best for the average lawn. Broadcast the seed by hand. In order to ensure uniformity distribution of seeds over a bed, use half the seeds first and sow remaining half in a crosswise direction. It is important to remember the best sowing time is when air is calm. 5
