This study illustrates the successful application of near-infrared reflectance spectroscopy extended with chemometric modeling to profile Cd, Cu, Pb, Ni, Cr, Zn, Mn, and Fe in cultivated fertilized Haplic Luvisol soils. The partial least-squares regression (PLSR) models were built predict elements present soil samples at very low contents. A total 234 investigated, their spectra recorded spectral range 1100–2500 nm. optimal preprocessing was selected among 56 different scenarios considering...

Field trials were conducted in 2004–2015, Bałcyny, on haplic Luvisol formed out of light boulder clay. The experiment consisted the following treatments: control (no fertilization), NPK, manure (FYM), dried pelleted sewage sludge (DPSS), composted (CSS), compost made from municipal and straw (SSCS), Dano unsorted household waste (CUHW), produced urban green (CUGW). Over a period 12 years, 30 t DM/ha each composts used, that is, 10 rotation crop sequence. Nitrogen fertilization was kept same...

The purpose of this study was to evaluate the effect ash from combustion plant biomass energy willow and Pennsylvania fanpetals on yields grown as an crop soil properties. A three-year pot experiment carried out substrates with a loamy sand texture. Ash application rates were based potassium fertilisation demand. An incubation determine biomass-based Three soils textural categories incubated for 3 months ashes, doses which determined basis hydrolytic acidity (¼; ½ 1.0 Hh). It found that...

Abstract The aim of this study has been to evaluate the effect sewage sludge and composted municipal waste on content various forms P in soil. experiment scheme: C, control; NPK; FYM; DGSS, dried granulated sludge; CSS, composed CSSS, straw; CMMW, mixed waste; CMGW, green waste. bound was determined fractions: F1, easily soluble; F2, exchangeable; F3, organic; F4, carbonate; F5, stable organic-mineral mineral bonds; F6, residual. NPK fertilisation as well soil with organic substances raised...

Abandonment of crop production on agricultural lands for several or more years is a widespread practice not only in Europe but also around the world. Economic and political considerations lead to abandonment poorest lands, although sometimes agriculturally valuable are excluded from farming. Fallow land can be afforested, designated as dedicated protection area, exposed natural succession, used grow biomass energy purposes. However, most important role should ensure food safety. The...

The proper fallowing of soil maintains or even improves its yield potential. aim this research was to compare five methods protection with high production potential on the and quality strategic plants. tested consisted variants: bare fallow—BF; natural fallow—NF; fodder galega (Galega orientalis Lam.)—FG; a mixture Lam.) smooth brome (Bromus inermis)—FG+SB; inermis)—SB. had been set aside for 9 years, after which time fallows were terminated fields cropped winter oilseed rape, wheat, spring...

PAHs belong to persistent organic pollutants (POPs) found in the natural environment. They eventually accumulate highest quantities soil. The purpose of this study has been determine soil depending on method applied control weeds rows a 4-year plantation hazel (mulch fabric, bark chips, sawdust, manure compost, bare fallow, chemical grass sward). concentration (16 PAHs) was kept as fallow. second most abundant these compounds determined under sward, followed by and fabric. Less accumulated...

Municipal sewage sludge can be used in agriculture provided that the permissible levels of heavy metals are not exceeded either or top layer soil to amended by this substance, and its application does deteriorate quality.The purpose study was determine effects different forms on content Cu Zn leachate.The comprised 2 rotations (potato, spring barley, winter oilseed rape, wheat).Each series composed following treatments: NPK, FYM, municipal composted with straw, dried granulated sewage.FYM...

Fodder galega is a perennial, wintering plant, which in recent years has been gaining popularity, mainly because of its useful characteristics. Many researchers have noted large yield potential and exceptional adaptability to various environmental conditions. The purpose this study was collect the most up-to-date knowledge about valuable member Fabaceae family. Green fodder, especially that made from young plants, possesses very good biochemical parameters allow it be used nutrition animals...

The use of biostimulants and cultivar selection play an important role in modern potato farming because they influence tuber yield quality.The nutritional value processing suitability tubers are affected by their content total protein, reducing sugars sucrose.The aim this study was to determine the effect on glucose, fructose sucrose (skin, flesh whole with skin), at harvest after 5 months storage.The experimental materials included five edible cultivars: Irga, Satina, Valfi, Blaue St....

The purpose of the study has been to determine direct and residual effect farmyard manure composts made from sewage sludge on content uptake copper zinc by crops growing in a four-field crop rotation system. In 2004-2007, field experiment was established proper grey-brown podzolic soil, originating light boulder clay, rich P, moderately abundant K low Mg, whose reaction pH = 5.04. involved cycle with following crops: potato, spring barley, winter oilseed rape wheat. design experiment, set up...

The objective of this study has been to follow modifications in the content Cu, Zn and Mn topmost layer soil which had fertilized for many years with farmyard manure mineral fertilizers or alone. Soil samples were collected 2002-2005 from a trial established 1986 on proper brown podsolic soil, according random block design four replication. first factor consisted organic fertilization (manure applied every two without manure). second involved different rates fertilization. Rates nutrients...

Fenugreek is one of the oldest known medicinal plants that have been used in traditional medicine many parts world. The aim this study was to determine effects nitrogen fertilization and Rhizobium meliloti inoculation on yield, yield components seed quality fenugreek. experiment performed during two growing seasons. Chlorophyll content determined with use SPAD-502 chlorophyll meter. After harvest, biometric measurements were chemical composition vegetative organs seeds fenugreek plants. At...

The influence of manure and composts on the leaching heavy metals from soil was evaluated in a model lysimeter experiment under controlled conditions. Soil samples were collected experimental fields, 0- to 90-cm layers retaining layout profile layers, after second crop rotation cycle with following plant species: potatoes, spring barley, winter rapeseed, wheat. During field experiment, 20 t DM/ha manure, municipal sewage sludge composted straw (SSCS), (SSC), dried granular (DGSS), "Dano"...

UAN is a popular nitrogen fertilizer, broadly used in world agriculture. Research concerning the effects of this fertilizer just as common. Contrarily, studies on combined application with P, Mg or S are lacking. This fact has stimulated our study, undertaken order to evaluate maize grown for grain and fertilized enriched macronutrients (P, S) crop’s yields metabolism. The following fertilizers were applied: 32%N, + S—26% N 3% S, P (Medium)—26% 11% P2O5, (Starter)—21% 18% Mg—20% 4% Mg. Based...
