2015/4/24
We evaluated the potential of crushed amphibolite and artificial slow-release N-P-K-Mg fertiliser to stimulate the survival, growth and nutrition of Norway spruce planted on an acidified air-polluted ...
Spectrum of the Pests on Cereal Crops and Influence of Soil Fertilisation
spring barley winter wheat
2015/3/2
Our research was realised on spring barley and winter wheat in Nitra-Dolná Malanta during 2004–2006. We
found that the total occurrence of the pests had decreasing tendency. The flea beetle (Phyllot...
The Effect of Fertilisation with Fermented Pig Slurry on the Quantitative and Qualitative Parameters of Tomatoes (Solanum lycopersicum)
