Horticultural substrates should promote seed germination and seedling emergence. The value of the SPAD index was significantly influenced by type substrate. had a beneficial effect on plant height in comparison with control Brassica plants grown used experiment compact growth habit, which is desirable trait production. In general, macronutrient uptake differed various substrates. Significant di...

AIMS This study compared the chemical, physical and bacterial composition of circulated and stagnant dairy wastewaters. METHODS AND RESULTS Samples taken from circulated and stagnant wastewater lagoons, over a 1-year period, were analysed for 10 chemical (total N, NH3, NO3, NO2, Na, Ca, HCO3, Fe, P and K) and six physical (biological oxygen demand, chemical oxygen demand, dissolved solids, el...
