DESCRIPTION:
Since 1966, the experimental design has been constituted of 108 open lysimeters (4 m2 each, 80 cm depht), filled with three types of soil; sandy, silty loam and clay. The design is randomised block with three replications.
Until 1986/87 the trial was conducted with a maize-wheat rotation, comparing 12 treatments deriving from the factorial combination of three nitrogen doses with four methods of crop residue management (removal of all the residues, burial of just the wheat straw, burial of just the maize stalks, and burial of the straw and stalks).
The annual doses of nitrogen were 0, 100 and 200 kg ha-1 for maize and 0, 80 and 160 kg ha-1 for wheat, splitting the distributions into 1/3 when incorporating the crop residues into the soil, 1/3 at sowing and the rest at canopy closure. The doses of P2O5 and K2O on all treatments were 150 and 200 kg ha-1, respectively.
From 1998 onwards a four-year rotation (Wheat – Sugarbeet – Tomato – Maize) was used. The management methods of the crop residues were simplified, comparing only two situations (burial of the previous crop residues or their removal), and the range of nitrogen doses was increased to 6 constant levels over the years (0, 50, 100, 200, 300, 400 kg ha-1) in a factorial combination with the burial or removal of the crop residues.
