Determination of the presence of an NG between fields on a farm and/or within a particular field, together with its size, requires a set of highly reliable diagnostic tools. The necessary set of diagnostic tools, based classically on pedological and agrochemical methods, should be currently supported by remote-sensing methods. A combination of these two groups of methods is the only way to recognize the factors responsible for yield gap (YG) appearance and to offer a choice of measures for its effective amelioration. The NG concept is discussed in the two first papers (Grzebisz and ?ukowiak, Agronomy 2021, 11, 419; ?ukowiak et al., Agronomy 2020, 10, 1959). Crop productivity depends on a synchronization of plant demand for nitrogen and its supply from soil resources during the growing season. The action of nitrate nitrogen (N-NO3), resulting in direct plant crop response, can be treated by farmers as a crucial growth factor. The expected outcome also depends on the status of soil fertility factors, including pools of available nutrients and the activity of microorganisms. Three papers are devoted to these basic aspects of soil fertility management (Sulewska et al., Agronomy 2020, 10, 1958; Grzebisz et al., Agronomy 2020, 10, 1701; Hlisnikovsky et al., Agronomy 2021, 11, 1333). The resistance of a currently cultivated crop to seasonal weather variability depends to a great extent on the soil fertility level. This aspect is thoroughly discussed for three distinct soil types and climates with respect to their impact on yield (Hlisnikovsky et al., Agronomy 2020, 10, 1160-Czech Republic; Wang et al., Agronomy 2020, 10, 1237-China; ?ukowiak and Grzebisz et al., Agronomy 2020, 10, 1364-Poland). In the fourth section of this book, the division a particular field into homogenous production zones is discussed as a basis for effective nitrogen management within the field. This topic is presented for different regions and crops (China, Poland, and the USA) (Cammarano et al., Agronomy 2020, 10, 1767; Panek et al., Agronomy 2020, 10, 1842; Larson et al., Agronomy 2020, 10, 1858). 606 $aBiology, life sciences$2bicssc 606 $aResearch and information: general$2bicssc 606 $aTechnology, Engineering, Agriculture, Industrial processes$2bicssc 610 $aa field 610 $aB 610 $aBeta vulgaris L. 610 $abiological index fertility 610 $acalcium 610 $acardinal stages of WOSR growth 610 $achlorophyll content index 610 $aclimatic potential yield 610 $acontents of available phosphorus 610 $acrop production 610 $acrop yield 610 $acrude protein content 610 $aeconomics 610 $afarmyard manure 610 $afield 610 $agrain yield 610 $ahomogenous productivity units 610 $aindices of N productivity 610 $aindigenous Nmin at spring 610 $amagnesium 610 $amaximum photochemical efficiency of photosystem II 610 $amicroelements fertilization (Ti 610 $amineral fertilizers 610 $amineral N 610 $aMo 610 $aN balance 610 $aN efficiency 610 $aN gap 610 $aN input 610 $aN total uptake 610 $aN uptake 610 $aNDVI 610 $anet return 610 $anitrate nitrogen content 610 $anitrogen indicators: in-season 610 $anitrogen use efficiency 610 $anitrogenase activity 610 $anormalized difference vegetation index (NDVI) 610 $anumber of spikes 610 $aon-the-go sensors 610 $aorganic manure 610 $aPCA 610 $apost-harvest Nmin 610 $apotassium 610 $aregional optimal nitrogen management 610 $aremote sensing-techniques 610 $asatellite remote sensing 610 $aseed density 610 $aSi 610 $asite-specific nitrogen management 610 $asite-specific nutrient management 610 $asoil 610 $asoil brightness 610 $asoil chemistry 610 $asoil constraints 610 $asoil enzymatic activity 610 $asoil fertility 610 $asoil properties, site-specific requirements 610 $aspatial 610 $aspatial variability 610 $aspectral imagery 610 $asubsoil 610 $asugar concentration 610 $asustainability 610 $atemporal variability 610 $aTriticum aestivum L. 610 $avegetation indices 610 $avertical variability of N demand and supply 610 $aweather conditions 610 $awinter oilseed rape ? winter triticale cropping sequence 610 $awinter triticale 610 $awinter wheat 610 $ayield 610 $ayield gap 610 $aZn) 615 7$aBiology, life sciences 615 7$aResearch and information: general 615 7$aTechnology, Engineering, Agriculture, Industrial processes 700 $aGrzebisz$b Witold$4edt$01328520 702 $aGrzebisz$b Witold$4oth 906 $aBOOK 912 $a9910566459003321 996 $aSite-Specific Nutrient Management$93038641 997 $aUNINA
