The aim of this research was to compare effects of fertilization with various ratios of N, P and K (N:P:K) on arbuscular mycorrhizal fungi (AMF) infection in roots of Dactylis glomerata in Ca-carbonate (limed) and non-limed meadow plots at the Research Centre of Skriveri, Latvia University of Agriculture. Dactylis glomerata roots were excavated from variously fertilizer plots, a minimum 3 root samples per plot and analysed for two consecutive years. Arbuscular mycorrhizal fungi infection rates were estimated according to accepted scoring tables used for determination of AMF colonization.

The aim of the experiment reported here was to evaluate the effects of an inoculant SIL-ALL**4x4 on the fermentation quality and chemical composition of silage made from meadow-fescue and meadow-foxtail. Inoculant SIL-ALL**4x4 provided the good quality of silage in all stages of maturity. Lactic acid fermentation of inoculated silage was very extensive, especially in the stages of ear formation of meadow-fescue. The results indicated that the use of inoculant improved fermentation and silage hygienic quality.
