Influence of container size and substrate mineral composition on transplant growth and yield of brocter transplantation. The aim of the study was to estimate the effect of container size and the type of substrate on plant growth, in the nursery, and their long-range effects on final yield in the field. In the nursery the variables analysed were the plant height, leaf dry weight and leaf area per p

Four new CII reference materials for the chemical analysis of plants: Pine needles, oak leaves, barllements (N, P, K, Ca, Mg, Na), the minor elements (Al, Cu, Fe, Mn, Zn) and the ash content (often necessary for X-Ray fluorescence analysis). Accuracy and precision are discussed. These four new substances complete the 21 reference materials offered already by the CII.

A rapid wet digestion method for plant analysis P by colorimetry. Standard addition of iron in the leaf samples avoided the interference of HNO. in AAS determination of Fe. The results are compared with the obtained by classical dry calcination (muffle) and other wet methods.
