Surface spreading is a method used in agriculture and environmental management to distribute materials evenly over the ground. This technique can involve spreading fertilizers, seeds, or other organic materials to enhance soil quality and promote plant growth. It helps ensure that nutrients reach the plants effectively and can improve crop yields. In addition to agriculture, surface spreading is also used in waste management. For instance, biosolids from wastewater treatment can be spread on land to recycle nutrients and improve soil health. This practice helps reduce waste while benefiting the environment and agricultural productivity.
