Soil testing methods are still largely the same as they were 100 years ago, and researchers and farmers continue to struggle to interpret the numbers. However, a soil test is a good place to start ...

Figure 1: Soil pH at 0.5 m depth versus annual water balance. Figure 2: Outliers from the global relationship between pH and MAP minus PET. By assuming a threshold between CaCO 3-buffered and Al(OH) 3 ...

Kikuyu (Pennisetum clandestinium Hochst) grew relatively poorly on the Wollongbar krasnozem at soil pH values below 4.36. At these low pH values dry matter yields were increased by raising the pH or ...
