From: Acidified manure and nitrogen-enriched biochar showed short-term agronomic benefits on cotton–wheat cropping systems under alkaline arid field conditions

Figure 5

A = Olsen P in cotton and B = Olsen P in wheat. Here CK = control (no AM or NeB), AM = acidified manure, NeB = nitrogen enriched biochar and AM + NeB = combination of acidified manure and nitrogen enriched biochar. The vertical bars indicate treatment means, while error bars show the standard deviation of means (SD; n = 3). The bars sharing similar letters are not significantly different from each other at p ≤ 0.05.
