Nitrogen dynamics and valorization for mulch-based cropping systems with direct seedings in the Brazilian Cerrados.

Eric Scopel , Alexandra Maltas , Marc Corbeels , Fernando Antonio Macena da Silva , Francois Affholder , et al.
Under humid or sub-humid tropical conditions, nitrogen is very often a limiting factor foragricultural production and its sustainability. A study conducted in the Brazilian Cerradosdemonstrated that direct seeding mulch-based cropping systems (DMC) improve N–use efficiencyby crops in such climates. On a long-term basis, N accumulated in soil organic matter at an averagerate of 83 kg ha-1 year-1 as a result of increased crop residue inputs to the plant-soil system. Afterten years of continuous DMC, the amount of N mineralized during the maize growing cycle (120days) increased with 25 kg N ha-1.At the short-term scale, the rate of decomposition of the residues was slow, primarily due toreduced contact with soil. There was no phase of N immobilization caused by decomposing microorganisms.The type of cover crop had little effect on N supply. Nevertheless, the introduction of acover crop can increase consistently N-use efficiency, reducing mineral N leaching by 25 to 50 %.The potential for N losses is indeed particularly high, since important amounts of residual mineralN are present in the soil profile at the beginning of the growing season when no cover crop has beengrown., Dec 2007, Antananarivo, Madagascar. 1 p
