Crop Response to Soil Acidity Factors in Ultisols and Oxisols in Puerto Rico. XIII. Cabbage
The Journal of Agriculture of the University of Puerto Rico
The effect of acidity factors of two Ultisols and one Oxisol on yield and foliar composition of cabbage was determined. On all soils, cabbage responded markedly in yield to liming, but response was stronger on the ultisols. All soil acidity factors correlated significantly with yields. On the Ultisols, yields increased with decreasing acidity up to the highest level of limiting, pH 5.6. Only 50% of maximum yield was obtained at 12-13%.
