The treatments were combined with three levels N...
Laser diffraction analysis is an alternative to standard sedimentation methods designed determine particle size distribution. In this article, five samples from the forested part of floodplain Svitava River in Czech Republic were analyzed. and hydrometer method performed for each sample. The divided according soil classification into two groups depending on their classification–group A group B. results laser compared. Correlation relationships between both established, values recalculated...
Abstract It was shown that the use of biochar provides many benefits to agriculture by improving whole complex soil properties, including structure. However, diverse range effects depends on its physicochemical application rates, initial properties etc. The impacts biochar, mainly reapplication soils and interaction with nitrogen in relation water-stable aggregates (WSA) did not receive much attention date. aims study were: (1) evaluate effect (in spring 2014) 2018) different rates (B0, B10...
Several studies have reported that biochar can improve soil properties which are linked with higher crop yields and this effect is long-term. This paper aimed to study the effects of (0, 10 20 t ha−1) its combinations N-fertilization (zero, first second level N-fertilization) after 3 4 years application on improving characteristics loamy Haplic Luvisol (Dolná Malanta, Slovakia). The results indicated an increase in pH (+7%), improvement sorption (hydrolytic acidity decreased by 11%, sum...
Climate change is affecting all sectors of human activities worldwide, including crop production. The aim the paper was to evaluate average daily air temperatures measured at one hundred meteorological stations across Slovakia in 1961–2010 and calculate maximum length vegetation period for Solanum lycopersicum L., Brassica oleracea L. var. capitata Daucus carota Future trends predictions temporal spatial development duration were elaborated decades 2011–2020, 2041–2050, 2071–2080 2091–2100....
Recent findings of changing climate, water scarcity, soil degradation, and greenhouse gas emissions have brought major challenges to sustainable agriculture worldwide. Biochar application proves be a suitable solution these problems. Although the literature presents pros cons biochar application, very little information is available on impact repeated application. In this study, we evaluate discuss effects initial reapplied (both in rates 0, 10, 20 t ha−1) combined with N fertilization (at...
The goal of this study was the spatial processing and showcasing selected soil properties (available water capacity, total organic carbon content clay fraction <0.001 mm) in Nitra River Basin (Slovakia) via usage subsequent evaluation quality applied interpolation methods (Spline, inverse distance weighting (IDW), Topo to Raster). results showed possibilities “conversion” point information obtained by field research as well laboratory into a expression, thus providing at least relevant...
One of the challenges harnessing higher productivity levels and sustainability agriculture related to N fertilization is in expanding soil N2O emissions, which has become a serious issue recent years. Recent studies suggest that biochar may be solution this problem, but there still knowledge gap application rates its reapplication Central Europe; therefore, study, we investigated effect (initial 2014 2018, respectively, at 0, 10 20 t ha−1) combined with N-fertilizer (N0—0 kg ha−1; N1—108...
The quantity and quality of soil organic matter (SOM) depending on many edaphic environmental factors may change in response to agriculture-related practices. SOM humification process can be supported by the application mineral fertilizers, but production vineyards, such information is lacking. NPK fertilizer alters quality, therefore, aim this study was to: (1) assess extent dynamics different (control—no fertilization; 1st NPK; 3rd levels) rates with grass sward cover a productive vineyard...
