**The sugarcane plant uses different mechanisms to absorb nutrients from the soil, which involve both physical and biological processes. One of the main mechanisms is active absorption, which occurs through the proton pump present in the root cells. This pump is responsible for maintaining the pH of the soil around the roots at around 4.5 to 5.5, which favors the solubilization of nutrients in the soil. Thus, nutrient ions such as nitrogen, phosphorus, potassium, calcium, and magnesium are transported to the root cells through specific ionic channels. In addition, sugarcane is also capable of forming symbiotic associations with soil microorganisms, such as nitrogen-fixing bacteria and mycorrhizal fungi. These microorganisms can provide nutrients to the plant and help improve water and nutrient absorption by the roots. Another important mechanism used by sugarcane is the production of low molecular weight organic compounds, such as organic acids and amino acids, which are released by the roots into the soil. These compounds can increase the solubility of nutrients in the soil and promote the growth of beneficial microorganisms, which in turn help improve nutrient uptake by the plant. In summary, sugarcane uses a combination of physical and biological mechanisms to absorb nutrients from the soil, ranging from the acidification of the soil around the roots to the formation of symbiotic associations with microorganisms and the production of organic compounds.** - Upscaled by <@1085374514927521832> (fast)
