  1. Crop production: Add slurry to the soil

    A replicated, randomized, controlled study in 2000–2003 in an irrigated maize field in Spain found higher crop yields in plots with added slurry, compared to plots without it. Crop yield: Higher maize yields were found in plots with added slurry, compared to plots without it, in two of three comparisons (7–12 vs 6–7 Mg/ha). Methods: Plots (3.8 x 2.5 m) had added slurry (30, 60, 90, or 120 Mg/ha) or no fertilizer (three plots for each). Maize was harvested in November each year.

     

  2. Crop production: Use organic fertilizer instead of inorganic

    A replicated, randomized, controlled study in 2000–2003 in an irrigated maize field in northeast Spain found lower crop yields in plots with organic fertilizer, compared to inorganic fertilizer. Crop yield: Lower maize yields were found in plots with organic fertilizer, compared to inorganic fertilizer, in one of four years (2003: 7–9 vs 10 Mg/ha). Methods: Plots (3.8 x 2.5 m) had inorganic fertilizer (150 kg N/ha) or organic fertilizer (pig slurry: 30, 60, 90, or 120 Mg/ha) (three plots for each). Maize was harvested in November each year.
