| Abstract: | Abstract Leaf samples were collected from 24 pecan trees on three dates 1 month apart in June, July, and August. Soil samples were collected in June from each site at three depths: 0–6, 6–12, and 12–18 inches. Correlations between leaf analyses and soil test values were significant for Zn, Ca, Mg, and P. Values were not correlated for K. There was a high negative correlation for leaf Mn and soil pH. Means of leaf analysis values for the three sampling dates were not statistically different for any element. The data indicate that soil sampling should be a satisfactory means of determining fertility needs of pecan orchards, except for N. |
