How can manure be used as fertilizer?

The chemical fertilizer for one acre of corn requires 5.7 million BTU. Thus, there is a savings of 4.3 million BTU (the equivalent of 9.74 bbl of oil) per acre using the organic fertilizer. U.S. livestock manure production is estimated at 1.7 billion tons per year, and more than half of it is produced in feedlots and confinement rearing. If 20% of the manure from confinement rearing and feedlots were used as fertilizer, it could serve 17 million acres (at 10 tons/A) and save 73 trillion BTU (the equivalent of 13 million bbl of oil) per year [ 27 ].

What is the purpose of adding P fertilizer to pasture?

In legume-based pasture and crop-production systems, P fertilizers are added to promote N 2 fixation by the legumes. Regardless of P fertilizer source, application of P to legume-based systems promotes N 2 fixation, thereby indirectly causing soil acidification. The amount of acidity produced indirectly by N 2 fixation depends mainly on the extent of NO 3 − leaching and it can be greater than that produced directly by the dissolution of MCP in superphosphate fertilizer granules ( Table 2 ).

How does nitrogen fertilizer produce H+?

Application of N fertilizers such as urea and ammonium sulfate to soils produces H + by two processes: nitrification (eqn [3.8]) and NO 3 − leaching. Part of the H + produced is neutralized by OH − released by plants during the subsequent uptake of the NO 3 − ions (eqn [3.9]). The depletion of basic cations (Ca, K, Mg, and Na) during the leaching of NO 3 − ions (i.e., as ion pair) and product removal (i.e., silage) accelerates the acidification process. In the case of ammonium sulfate, the concomitant leaching of SO 4 2 − and NO 3 − ions causes greater depletion of basic cations. With urea, the initial conversion of amide N (R-NH 2) to NH 4 + (ammonification) releases OH − (eqn [3.5]), which neutralizes part of the H + produced during the subsequent oxidation of NH 4 + to NO 3 −, explaining why urea-based N fertilizers are less acidifying than the NH 4 + -based fertilizers ( Table 2 ).

What is elemental sulfur?

Elemental sulfur (S 0) is used as an acidifying agent, as a slow-release S fertilizer or, in a finely divided form, as a fungicide. When S0 is added to soils, it is oxidized to sulfuric acid, which dissociates into SO 4 2 − and H + ions (eqn [3.13]). View chapter Purchase book. Read full chapter.
