Establishment of Native Grasses with Biosolids on Abandoned Croplands in Chihuahua, Mexico

Table 4

Grass species height (mean ± SE) of blue grama (Bouteloua gracilis) and green sprangletop (Leptochloa dubia) under different biosolids rates at a seeded abandoned field in Chihuahua, Mexico.

Biosolids rate (Mg ha^−1)	Blue grama (cm)	Green sprangletop (cm)
0	27.2±4.8^cA	19.6±4.8^bA
10	71.6±4.8^aA	84.4±4.8^aA
20	52.2±4.8^bB	81.1±4.8^aA
30	39.1±4.8^bcB	83.3±4.8^aA

Biosolids rate mean values followed by different lowercase letters within each grass species are significantly different (𝑃<0.05; 𝑛=24). Grass species mean values followed by different uppercase letters within each biosolids rate are significantly different (𝑃<0.05; 𝑛=24).
