How about further reducing costs with laboratory products and starting to feed your land with more nutritious elements?
With biofertilizers this is possible. Considered a renewable fertilizer, usually resulting from the treatment of organic waste, biofertilizers are by-products of biodigestion and are extremely important, as is the biogas itself.
With them, the reduction in the consumption of chemical fertilizers is real. Farming and livestock are grateful, as they promote growth by increasing the availability of Potassium (K) and supply of nutrients such as Nitrogen (N). In this sense, biofertilizer may not be the protagonist of your business model, but it can certainly represent an alternative complement to increase productivity and profitability.
