|Abstract:||The alfalfa crop in the irrigated land of the Ebro Valley stands fundamentally on three types of soil.
The five most outstanding factors controlling the mineral composition of the plant are: (i) genus, species and variety; (ii) type of soil; (iii) climatic conditions; (iv) state of maturity; (v) application of fertilizers.
In this report the second factor will be indicated by showing the comparative data of the alfalfa composition harvested on the three types of soil.
The second-year alfalfa fields (Aragon ecotype), were fertilized and treated under the same conclitions. The cuttings and harvesting of the material took place when 10% of the plants were flowering, on the following dates:
lst cutting: May 8, 1970
2nd cutting: June 19, 1970
3rd cutting: July 21, 1970
4th cutting: August 25, 1970
5th cutting: October 6, 1970
The vegetal matter was analysed according to the standards established by the Member Laboratories of the Inter-Institutes Committee for the Study of Analytic Techniques of Foliar Diagnosis.|
