Description
● The long-term experiment with amendments and fertilizers was located in the fall of 1961 according to the method of subdivided plots in a bifactorial manner.
●The amendment factor "A" includes 9 gradations in terms of dose (0, 2.5 and 5 t/limestone/ha) and frequency of application, covering a wide range of possibilities for the effective implementation of these improvement measures in practice.
● In these experiments, the fertilization factor presents 8 gradations and is of the "MANGELVERSUCH" type, a concept valid for the stage in which the experiences were located and in an area where there was a complete lack of information regarding the effect of fertilization. Unfortunately, worldwide there is relatively few stationary experiences with the amendment of acid soils, and in the existing ones the "amendment" factor does not present several gradations. Fertilization was carried out with ammonium nitrate, concentrated superphosphate, potassium salt 40% and semi-fermented cattle manure.
Design description
The bifactorial experiment is divided into 4 replicates. each replicate consists of 3 blocks, with 72 different plots, overall, the experiment consists of 288 plots of 6 m x 7 m size.
