After harvesting corn, it is a common practice to clean the field from the remaining plant stems, destroy insects and other pests, or burn the corn stubble to destroy the stubble easily and costlessly, but it is extremely damaging to the field. Stubble burning poses one of the major threats to corn yields. Organic matter, which is already less than 1 percent on the territory of Turkey, is further destroyed by the burning of stubble, which is a vegetable residue. Organic matter in the soil is of great importance in terms of corn yield. Humus, a decomposition product of organic matter, forms the source of some of the nutrients necessary for the development of plants. In addition to being a source of nutrients, organic matter also prevents its transport by erosion, ensuring the absorption and retention of precipitation water in the soil and ensuring clustering in the soil. It also provides good aeration of the soil. In short, reducing or destroying the amount of organic matter makes soils more inefficient.
In Modern agricultural techniques, burning your stubble is an extremely wrong method. It is also not possible to compensate for most of the damage caused by burning. First, by burning stubble, organic matter in the soil is destroyed, while the loss of carbon and nitrogen, which promotes plant growth, also increases. As the nutrients in the soil are destroyed, it is inevitable that you will see a decrease in corn yield of grain and silage.
Another harm of stubble burning is that it kills microorganisms found on the surface of the soil. However, as a result of the activities of these creatures, which are found in the soil and are not visible to the eye, organic matter breaks down, decomposes and turns into a form called humus. In trials, it is seen that there is a decrease in root rot disease in the first year with stubble burning, but this disease increases further in the second year. In addition, stubble burning makes the soil more susceptible to water and wind erosion. Because stubble prevents precipitation from falling violently into the soil, reduces the surface flow rate and allows it to seep into the soil.
Apart from being used as animal feed by burning stubble, the stalk/straw, which has many benefits, is also destroyed. Stubble fires can damage not only burned fields, but also places such as neighboring fields, gardens, fences, telephone poles, forests, Groves, wooded areas. However, stubble burning disrupts the natural balance and also causes air pollution.
As a result, stubble burning in the long term causes soil organic matter, which is already low, to fall, while fertile agricultural areas go towards barrenness. This leads to gradually lower efficiency from the unit area.
The spread of tools for mixing crop residues into the soil will positively affect the yield, and at the same time, natural life and the environment will be protected. Burning corn stubble means that our farmers are damaging their land with their own hands, so we, as the DEKALB family, advise our producers to avoid this irreparable damage.
