Soil: Add manure to the soil
A replicated, controlled study in 2006 in an almond orchard in Italy found more organic matter, nitrogen, and higher pH levels in plots with added manure, compared to plots without added manure. Organic matter: More carbon was found in plots with added manure, compared to plots without added manure, in four of six comparisons (8,173–9,420 vs 7,339–8,263 mg/kg). Nutrients: More nitrogen was found in plots with added manure (1,027–1,280 vs 727–827 mg/kg). Higher pH levels were found in plots with added manure, in one of six comparisons (8.57 vs 8.31). Methods: Plots (495 m2) had manure pellets (1.5 t/ha) or no fertilizer (three plots for each). Plots were drip-irrigated (2,000 m³/ha/year). Soil samples were collected in 2006 (five samples/plot, 0–15 cm depth).

Soil: Use organic fertilizer instead of inorganic
A replicated, controlled study in 2006 in an almond orchard in Italy found more carbon and nitrogen, and higher pH levels, in plots with organic fertilizer, compared to inorganic fertilizer. Organic matter: More carbon was found in soils with organic fertilizer, compared to inorganic fertilizer, in seven of 12 comparisons (8,173–9,420 vs 7,307–8,740 mg/kg). Nutrients: More nitrogen was found in soils with organic fertilizer, compared to inorganic fertilizer, in 10 of 12 comparisons (1,027–1,280 vs 760–1,037 mg/kg). pH: Higher pH levels were found in soils with organic fertilizer, compared to inorganic fertilizer, in six of 12 comparisons (pH 8.3–8.8 vs 7.5–8.0). Methods: Plots (495 m2) had organic fertilizer (manure pellets: 1.5 t/ha) or inorganic fertilizer (300 kg/ha in summer; three unspecified doses in spring) (three plots for each fertilizer). Plots were drip-irrigated (2,000 m³/ha/year). Soil samples were collected in 2006 (five samples/plot, 0–15 cm depth).
