Why Should Farmers Choose Biosolids Over Chemical Fertilizers?

There is a reason for everything, even choosing basically domestic waste over chemical fertilizers that have been produced by reputable agricultural companies from around the world. Yes, sometimes, even biosolids coming from waste is better than the continued commercialism of the agriculture industry.

Commercial-grade fertilizers have long been used to hasten the growth of crops and to provide essential nutrients such as nitrogen, phosphorus, and potassium. The cost of using chemical fertilizers, however, led many agriculturalists to look for options that would deliver the same “service” but without the price tag. Enter biosolids, which is basically an end-product of treated wastewater sludge.

You know the wastes you see in your homes? When these are treated, it turns into a liquid form to remove the pathogens and other contaminants. But not everything can be liquified, and the solids will somehow still carry hazardous materials if left untreated. When these solids are treated, it turns into biosolids, an organic material that we can use on land application to help the growth of crops, plants, and even vegetation. It is harmless to humans and contain almost zero trace of pathogens and other contaminants.

The reason why many farmers and agriculturalists are turning to biosolids instead of continuing to use what they have been applying on land for decades is because of the lower cost and the better benefits. Also, the supply of chemical fertilizers will decrease in the years ahead because of the depletion of the natural production of phosphorus.

On the other hand, biosolids contain in generous amount the three most important nutrients—nitrogen, potassium, and phosphorus—for any farmer or agriculturalist. The reason why gardeners, farmers, and agriculturalists use chemical fertilizers is to source out these three nutrients. Biosolids have these in large doses because of the treatment process’ inability to break down sludge completely. The result is the quantifiable amount of these nutrients.

Biosolids, compared with commercial fertilizers, are also less costly because technically, the resource for it is garbage or wastewater sludge. There are no additional materials that have to be combined with the mix to produce an end-product like biosolids. All the producers need is to collect as much domestic waste as possible, then turn its product (wastewater sludge) into biosolids. There is basically no expense in sourcing the materials needed for biosolids, except for the equipment and machines needed.

The benefits of using biosolids far outweigh the advantages of using chemical fertilizers. Sometimes, it is as simple as that.
