Směsná minerální hnojiva versus vápnitý dolomit: srovnávací studie z pěstování prostokořenného sadebního materiálu smrku ztepilého = Compound fertilisers versus dolomitic limestone: comparative study of bare root Norway spruce nursery stock production

The work presents results of a case study in nursery planting bare root seedlings of Norway spruce (Picea abies /L./ Karst), assessing opportunities in intensification (fertilizers, preparations) of nursery stock cultivation in slightly acid-to-neutral soil. Following fertilizers were used: (1) mineral fertilizers with specific composition of N-P-K-Mg, with admixture of growth regulators, (2) auxiliary plant preparation, and (3) dolomitic limestone. Effect of the chemical amelioration was evaluated via soil reaction, nutrient amount in soil, C/N ratio, base saturation, plant nutrition, biometrical parameters and health status. The dolomitic limestone increased calcium and magnesium in soil considerably and reduced biomass production. Liming affected nutrient status rather negatively, compared with the mineral fertilizers and imbalanced nutrient levels on soil colloids. Slight decrease in soil reaction resulting from application of physiologically acidic fertilizers was considered suitable with regards to ecological demands of Norway spruce. Combination of fertilizer and auxiliary plant preparation increased production of assimilatory organs and fine roots; suitable shoot/root ratio was also maintained. The use of growth regulators and auxiliary plant preparations can be acceptable in order to achieve optimal nursery stock quality under suboptimal soil conditions. … full description
