Blending topsoil/establishing new lawns
When making blended topsoil, the recommended mixture is one part compost mixed with four parts soil. To establish a new lawn, apply one inch of LinGRO compost to the topsoil, and mix thoroughly within the subsoil. It is recommended that clay soils be rototilled prior to adding LinGRO compost. One cubic yard of compost will cover a 325 square foot area at a depth of one inch.
For athletic fields and large open spaces, apply compost at a rate of 135 cubic yards per acre for a one-inch layer of compost.
United States Environmental Protection Agency (EPA) research shows that compost can suppress common turf diseases and reduce the need for fungicides. Aerate the lawn and spread LinGRO compost about 1/8 inch to 1/4 inch deep, and water thoroughly. One cubic yard of LinGRO compost will cover a 1,296 square foot area at a depth of 1/4 inch (2,592 square feet @ 1/8 inch).
Improving clay soil
Lincoln and Lancaster County have a high percentage of clay soils. Applying LinGRO compost to clay soils will improve the porosity, water holding capacity, and nutrient content, and add beneficial microorganisms to the soil. LinGRO compost will improve the structure of clay soils to encourage plant growth. Application rates depend on the amount of clay in the soil and the soil’s characteristics.
LinGRO compost may be used to improve water retention in new sod. Compost will also decrease the bulk density of the underlying soil, which helps establish plant growth. According to the EPA, using compost should reduce the need for fertilizers. However, nutrients may need to be applied depending on the characteristics of your soil.
Tree and shrub planting
Apply one to two inches of LinGRO compost on the surface of the ground in a radius not to exceed the drip line of the plant. For best results, aerate prior to application, or mix in with soil from the hole for planting the tree or shrub.
Flower and vegetable gardens
LinGRO compost may be used to enrich the soil in flower and vegetable gardens. Apply a one-inch layer of LinGRO compost over the entire garden area and till into six inches of soil. LinGRO compost may also be used to amend the soil and increase infiltration rates in rain gardens. Application rates depend on infiltration rate and the soil's characteristics. An infiltration test can help determine what amendments are needed.
Using compost in tree nurseries can enhance tree growth. According to the U.S. Composting Council, nursery fields amended with compost can produce a higher quality plant in a shorter amount of time. LinGRO compost will reduce soil erosion, add organic matter and nutrients to soil, and retain more water in the soil. Add fertilizers and make pH adjustments as necessary when applying LinGRO compost. The application rate will vary depending on your soil characteristics. The U.S. Composting Council says successful application rates for nurseries may range from one-half to four inches. Disking the field or tillage is recommended prior to application.
Till LinGRO compost into the soil at a rate of six to ten inches for a one- to two-inch application (12 to 14 inches for thicker layers).
LinGRO compost promotes the establishment of vegetation through the work of added nutrients and microorganisms. The woodchips in LinGRO compost help to stabilize slopes and improve soil structure more effectively than other forms of mulch. LinGRO compost will promote the development of plant growth, which enhances bank stabilization.
Apply a two-inch layer of LinGRO compost directly on the soil of the slope. For steeper slopes, a small berm or mound of wood chips at the top and bottom of the slope may help to slow quick moving water and prevent the runoff of nutrient-rich soil.
