The Difference Between Biosolids And Chemical Fertilizers



Commercial-grade fertilizers have long been used to hasten the growth of crops and to provide it with essential nutrients such as nitrogen, phosphorus and potassium or NPK. However, because commercial chemical fertilizers are generally more expensive than other organic and natural fertilizers, agriculturalists are looking at diverse and differing options like biosolids to provide plants with the needed nutrients to grow.

Environmentally, the natural production of phosphorus has been depleted because of the ever-increasing commercialization of its resources. The issues would, of course, naturally force scientists and researchers to find more ways for plants to get their needed nutrients without using chemical fertilizers. The answer to this seemingly insoluble problem is the use of biosolids as fertilizers.

Cost efficient

The process of turning sewage sludge into biosolids and thus, fertilizers, is tedious and costly. But the end product can be sold for less the price than commercial-grade fertilizers. Compared to chemical fertilizers and pesticides, biosolids fertilizers cost less especially when bought in bulk. Since the resource for biosolids is technically garbage or wastewater sludge, as it is more technically termed, the end product is decidedly cheaper than fertilizers made out of expensive chemicals and substances.

Nutrients and organic matter

Biosolids contain the three most important plant nutrients—nitrogen, potassium, and phosphorus—in generous amount. The reason why farmers, gardeners, and agriculturalists use commercial fertilizers and other substances is to get the needed nutrients through these channels. Biosolids has these nutrients and organic matter in large doses. Because biosolids came from wastewater sludge, the inability of the treatment plant to break down the sludge leads to a quantifiable amount of the said nutrients.

Sustainability

In order to sustain this environmental process, it is vital that the biosolids created from wastewater sludge be returned to the soil. This is crucial to the sustainability of the ecosystem, as well as the protection of the environment against total degradation. Besides sustainability, the use of biosolids and organic fertilizers also prolongs the instance when farmers would want to turn to chemical fertilizers. The dependability of farmers on chemical fertilizers these days would be greatly reduced if the production of organic fertilizers will receive the support it needs from relevant agencies.

Using biosolids for agricultural needs has many benefits, chief of which is the reduction of waste material that goes into landfills. Instead of the wastewater sewage being disposed through many environment unfriendly methods, producing biosolids through it is advantageous both for the environment and for society at large.
