Low carbon content in todays agricultural soil

Agriculture provides us with the food we need to survive. Unfortunately, human greed and excessive use of chemicals along with climate changes have led to the lowering of our natural carbon content in today’s agricultural soil. Having a low carbon content in soil can have negative impacts on soil health, crop productivity, and the environment.

Soil carbon is basically the amount of organic matter present in the soil. This includes both soil organic matter and inorganic carbon as carbonate minerals. It is mainly found in the topsoil. It plays a very important role as it dictates soil health and impacts many of the soil’s essential functions. Having a good carbon content in the soil helps in providing nutrients to plants, stores water and also supports the growth of beneficial microbes. Adequate carbon content also helps to sequester carbon from the atmosphere, which can help to mitigate climate change.

Reduction in soil carbon leads to a reduction in soil health and productivity. One of the major reasons for lower carbon content in the topsoil is the extensive use of chemical and synthetic fertilizers and pesticides. Most of these chemicals are effective in improving crop yields, but they also destroy natural beneficial microbes in the soil that play a crucial role in soil carbon sequestration. This further leads to soil erosion, which also contributes to the loss of topsoil carbon. Tilling practices have increased in the last 2 decades. Tilling disrupts the soil structure which further leads to the loss of organic matter. In the tilling process, the organic matter is exposed to the atmosphere by which it gets exposed to more oxygen which leads to carbon breakdown more quickly.

Low topsoil carbon content can lead to reduced crop yields, lower soil fertility, and increased soil erosion. If we look at the bigger picture then low soil carbon content also contributes to climate change. The topsoil carbon can help to remove carbon from the atmosphere and store it in the soil thus reducing the number of greenhouse gases in the atmosphere.

Regenerative agriculture practices is one of the most effective ways to increase soil carbon content Regenerative agriculture works on the principle of sustainability where it prioritizes soil health first. This can include reducing tillage, rotating crops, using cover crops, and incorporating livestock into the farming system. Reduction in the use of chemical fertilizers and pesticides can help to increase soil carbon content. The use of natural beneficial microorganisms for agriculture also helps to retain and also increase the carbon content in the topsoil. All practices which can help us to preserve the beneficial microbes in the soil are welcome.

Importance of in-situ faecal degradation in septic tanks
Importance of in-situ faecal degradation in septic tanks

Even in today’s time, septic tanks are an essential component for many because access to public sewage systems is limited. Septic tanks are basically designed to collect and treat wastewater from toilets, sinks, and other sources with the help of a natural process called “bioremediation”. In-situ faecal degradation plays a significant role in treating human waste and preventing the release of harmful pathogens into the environment.

In-situ faecal degradation is the process by which naturally present microorganisms in the septic tank break down and digest the solid waste that enters the tank. Most of the natural microorganisms responsible for this process are anaerobic in nature i.e. they do not require oxygen to function. Most of these microorganisms are naturally present in human solid waste and they play a critical role in breaking down the organic matter in the solid waste. The way this process works, it that the microbes such as bacteria break down the organic matter in the solid waste and convert it into simpler compounds like methane, carbon dioxide, and water. Due to this simple nature’s process, a large amount of solid waste in the septic tank is lowered and gets liquified which helps in better percolation and also prevents it from overflowing or clogging the system. It also helps in controlling the release of pathogens in our environment, by a principle of competitive exclusion.

With the growth in science and technology, a lot of antibiotics and other chemicals are widely used in modern society. Antibiotics are commonly used to treat bacterial infections, and chemical residue can be found in various sources such as drugs, personal care products, and household cleaning agents. After these chemicals are consumed or used, they are processed by the body and eventually excreted in urine or faeces. All of these residues eventually find their way into the septic tanks.

One of the most significant concerns associated with antibiotic and chemical residue in human waste is the development of antibiotic-resistant bacteria. When antibiotics are excreted in human waste, they can enter the environment and contribute to the growth of antibiotic-resistant bacteria. These bacteria can then spread through water and soil, potentially impacting other animals and humans. Also such chemicals can kill of the natural microbial community which was capable of the degradation of human waste. This leads to improper treatment of sewage before being released into the environment, which can lead to eutrophication in our natural water bodies. This also leads to the failure of s septic tank.

One of the most effective ways to reduce the impact of antibiotic and chemical residue in human waste is through use of natural robust microbial cultures in your septic tank. A good microbial community can effectively remove most of the antibiotics and chemicals present in human waste before it is released into the environment.

Further individuals can take steps to reduce their use of antibiotics and chemicals, which can help to reduce the amount of residue that ends up in human waste. Switch to the use of natural cleaning products, and try to reduce the use of pharmaceuticals whenever possible
