Manganese (Mn) is often underestimated in plant nutrition. Its availability to plants is influenced by several factors, which can lead to Mn deficiency or toxicity. The objective was to evaluate the transformation of soil Mn over 21 years in a long-term field experiment. Fertilising with (i) sewage sludge 1 (SS1); (ii) sewage sludge 3 (3 times higher nitrogen (N) dose, SS3); (iii) farmyard manure (FYM); (iv) mineral nitrogen, phosphorus and potassium (NPK) and (v) mineral nitrogen in addition to straw (Nst) was studied to evaluate the transformations of Mn in soil using different extraction methods at the 5 locations. There was a general reduction...

A field experiment was conducted with potatoes to examine the effects of hydrogel application and weather conditions on total tuber yield and the content of potentially harmful compounds – glycoalkaloids and nitrates. The first experimental factor comprised three table cultivars: Lawenda, Rima and Provita. The second factor consisted of three treatments: the application of the hydrogel AgroNanoGel Basic at 60 and 90 kg/ha, and a control treatment without hydrogel. Statistical analysis demonstrated significant effects of cultivar, hydrogel application rates, and hydrothermal conditions in the study years on potato tuber yield. The highest yields...

Nitrogen fertiliser is a key determinant of rice yield and grain quality; however, the synergistic mechanisms through which nitrogen regulates root anatomical structure, physiological traits, and cooking quality in rice varieties with different eating properties remain unclear. In this study, a pot experiment was conducted using two moderate-eating-quality cultivars (Xudao 3 and Huageng 9) and two superior-eating-quality cultivars (Zhengdao C42 and Nangeng 9308) under four nitrogen levels (0, 0.59, 1.18, and 1.76 g/pot, designated as N0, N1, N2, and N3, respectively). Cooking quality was assessed by amylose content, gel consistency, and alkali spreading...

Alluvial soils have high importance for both agriculture and biodiversity; however, these soils can also contribute to greenhouse gas (GHG) emissions including carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4). In this study, we examined GHG fluxes of three grassland and two cropland sites with alluvial soils in Abava river floodplain, Latvia (Europe). Soil CO2 fluxes representing heterotrophic respiration (Rhet) were determined using a portable CO2 gas analyser, while ecosystem respiration (Reco), soil CH4 and N2O fluxes were quantified using...
