“…Although mineral fertilizer can rapidly increase the yield of jujube in the first few years, it will lead to a decrease in yield after long‐term application. These observations were also made by other researchers (Matějková, Kumhálová, & Lipavský, ; Menšík, Hlisnikovský, Pospíšilová, & Kunzová, ), for example, Matějková et al.

We also found that soil SOC showed a highest relative contribution to yield, suggesting that the application of manure had a strong and positive impact on crop yield over years, by increasing SOC stock and soil nutrients, and alleviating salination.…”

Irrigation and fertilization management are important for controlling agricultural soil salinity and increasing productivity in extremely arid regions. The objective of this research was to evaluate the effects of long‐term drip irrigation and organic fertilizer application on soil salinity, fruit quality and yield of jujube [Ziziphus ziziphus (L.) Karst]. We established a 7‐yr field experiment in a desert‐oasis area in Northwest China. Six treatments were performed: CK (conventional irrigation, no fertilizer), CIMF (conventional irrigation, mineral fertilizer), CIOF (conventional irrigation, organic fertilizer), DI (drip irrigation, no fertilizer), DIMF (drip irrigation, mineral fertilizer), and DIOF (drip irrigation, organic fertilizer). The results showed that soil organic carbon (SOC) concentration in soil treated with organic fertilizer increased gradually over years. Treatment DIOF favored the accumulation of SOC with the highest content and stock after 7 yr. Lower salt content in root zone was found in DIOF after 7 yr. The yield of DIOF increased annually and reached an equilibrium level after the fourth year (14.88 to 16.69 Mg ha−1). Total carbohydrate and vitamin C (Vc) of DIOF of fruit were all significantly higher than CIOF and DIMF. The boosted regression tree showed that SOC content had the highest relative contribution rate to jujube yield. Path analysis identified the most important factor affecting SOC in the drip‐fertigation system was the input of organic fertilizer, with path coefficient 0.65. Long‐term combination of drip irrigation and organic fertilizer application would be an effective strategy maintaining productivity and improve fruit quality in extremely arid areas.

The main aim of this study was to determine the intensity of hydrophobic/hydrophilic components of the soil's organic matter as well as its hydrophobicity. Non-destructive Fourier Transform Infrared (FTIR) spectroscopy was used for the diagnosis and characterization of the basic classes of the chemical groups (hydrophilic and hydrophobic components) from which the organic matter in the soils is formed. Soil samples (depth 0-30 cm) were taken from the topsoil of the 70 sampling sites from the experimental field at Prague-Ruzyne (Czech Republic) during [2007][2008][2009], where a conventional soil tillage technology was used. It was found that the variability of the intensity of the hydrophobic components is greater (27.6%) than that of the intensity of the hydrophilic components (6.2%), which correlated significantly with the C org (r = 0.58; P < 0.05) and N t (r = 0.65; P < 0.05) in the soil. It was proven that the soil samples with a higher proportion of coarse grains are more hydrophobic than those with higher proportions of clay. Data about soil hydrophobicity can help to evaluate the soil quality parameters as well as the soil fertility.

“…The high density of subsoil archeological features in the lowlands of Central Europe (see Gojda 2004;Hejcman and Smrž 2010) is thus responsible for an indispensable proportion of spatial variability in crop production, although this variability has never been investigated previously. With respect to the high differences in subsoil chemical properties and crop production between cropmarks and their surroundings, the small-scale variability in crop production induced by subsoil archeological features cannot really be removed by the use of precision agricultural technologies such as site-specific application of agrochemicals (Bachmaier and Gandorfer 2009;Matějková et al 2010). This is because the cropmarks are frequently too small to be detected by sensors or to receive different amounts of agrochemicals compared to their surroundings.…”

During an aerial archeological survey performed in spring 2009, we detected positive cropmarks (increased biomass production) indicating waste pits in the subsoil in a winter wheat (Triticum aestivum L.) stand. Based on pottery samples, the waste pits were dated to the end of the twelfth century or to the first half of the thirteenth century. The aim of this study was to investigate whether there were any differences in the soil chemical properties in arable and subsoil layers between cropmarks and the surrounding stands (controls) with normal crop growth. We also investigated how plant performance and biomass chemical properties differed between the cropmarks and controls. There were no differences in pH between cropmarks and controls in the 0-20 cm arable layer, but a substantially higher pH was recorded in the subsoil layer (30-40 cm) in cropmarks compared to controls, indicating deposited wood ash. Similar results were recorded for plant available (Mehlich III) P, Ca, Mg, As and Zn concentrations. Plant height, spike length, flag leaf length, tiller density, spike density and standing dry matter biomass were substantially higher in cropmarks than in controls on both sampling dates (
