Adequate management of agricultural crops requires, among other things, accessible and sufficiently accurate methods for assessing plant nutrition crop vegetation status production estimation. Sustainable technologies are based on correct decisions, prompt interventions appropriate works, information in real time, the obtaining can be simple, accessible, relation to different user categories (e...

Jagos P., V. Dvorak, J. Bouda: Levels of Minerals in the Blood Plasma of Cows and their Calves fed from Buckets. Acta vet. Brno, 50, 1981: 33-41. The concentration in plasma of calcium, magnesium, inorganic phosphorus, zinc, copper and iron in 40 cows and their calves up to the age of three months was followed in winter season under conditions of large-scale technology. The statistically signif...

An important stage of the designing process in the machine-building industry is the optimization of the strength characteristics of a new product--one of the aims of the said optimization being the reduction of material content of machines and mechanisms. However, carrying out strength investigations via fuU-scale testing of prototypes and models calls for considerable material, labour and time...

The aim of this study was to evaluate the effect of three different chemical feed phosphates on the blood biochemical indicators and the content of main minerals of bones in finishing pigs. Over a period of 85 days of fattening, monocalcium (MCP, Finnish product), dicalcium (DCP, Polish product) and calcium-sodium (CSP, Russian product) phosphates were used in fattener feeding. The feeding was ...

The reduction of atmospheric sulphur dioxide pollution is causing increasing problems of sulphur deficiency in sulphur-demanding crop plants in northern Europe. Elemental sulphur and many sulphur containing compounds such as cysteine-rich antifungal proteins, glucosinolates (GSL) and phytoalexins play important roles in plant disease resistance. The aim of this work was to analyse the effect of...
