Topsoil is the uppermost layer of earth where plants usually flourish. It is important to keep it healthy and in place. The reduction of nutrients and erosion are two of the problems that occur in it. The reduced nutritional value means that planting will be futile in this part of the garden. If erosion happens, the lower layer, which is has little nutritional value, is exposed. Luckily, there are several things you can do to help keep your soil in place and your plants growing strong.
One way to keep topsoil in place (to avoid erosion) is use ground cover. Ground cover is the term that is used for grasslike or brushlike growth that is very low to the ground. The low growth helps to keep the wind from blowing away the soil as well as holding on to it to keep light rain from sweeping it away. It serves as a net that holds almost everything in place. The cover also helps to keep the moisture from evaporating immediately, even under the heat of the sun. There are some kinds of cover that are leguminous, and these serve another purpose by anchoring their roots and holding on. These also contribute to the nitrogen content of the ground, which is important for the next planting. It should be noted that ground cover technique is often used when there is a need to revive the soil.
Mulching can also be a great way to maintain topsoil Auckland. This method utilizes organic and, sometimes, non-organic materials as a covering. Since there are different kinds of materials that can be used for mulching, the gardener can choose which suits his or her purpose best. Organic mulch can be made from wood and dead leaves. These serve the same purpose as ground covering by weighing down on the earth to prevent it from washing away due to rain or from being blown away by the wind. Mulch is also a good way to trap moisture, thus creating an environment where the organic matter decomposes, possibly serving as fertilizer.
Compost is also another way to nourish the soil. Organic materials decompose easily in the soil and make it dense and moist. Density helps to weigh it down and prevent loss through erosion. Density also acts as a method to gather moisture to the compost and retain it. As a fertilizer, compost may not be complete, but it can prevent further reduction of nutrients from the earth. Some organic fertilizers can be added to earth to complete the necessary needs of the plants. For some gardeners or farmers, the compost is added to prime the soil before planting is done.
Making terraces on slopes and defining plots properly can also help to prevent topsoil loss. The terraces prevent ground loss by making the terrain’s trajectory less prone to erosion. On the other hand, defining plots can also reduce erosion because of the canals that are built around each plot. The canals help to guide water flow.
