“…Intensive conventional agriculture has also been used, to a greater or lesser extent, on the fertile soil in Vojvodina Province, Serbia, and over the years has decreased organic matter content and changed soil structure [4]. The studies of Belić et al [5] and Seremesic et al [6] confirm a decline in the soil organic matter in this region. This decline became a serious concern considering that further agricultural demands and food production under the more obvious climate changes in the 21st century will require maintaining or improving soil fertility and productivity [7].…”

Soil and water conservation benefits of cover crops have been hypothesized as a way to mitigate and adapt to changing climatic conditions, but they can also have detrimental effects if rainfall is limited. Our objective was to quantify effects of winter cover crops on soil water storage and yield of silage maize under the agro-ecological conditions within Vojvodina Province in Serbia. The experiment was conducted under rain-fed conditions at three locations and included a control (bare fallow) plus three cover crop and two N rate treatments. The cover crop treatments were common vetch (Vicia sativa L.), triticale (x Triticosecale Wittm. ex A. Camus) and a mixture of the two species. All were managed as green manure and subsequently fertilized with either 120 or 160 kg N ha −1 before planting silage maize (Zea mays L.). Cover crop effects on soil water storage were calculated for two periods, March-May and May-September/October. A Standardized Precipitation Index (SPI) used to characterize drought severity for 2011/2012 and 2012/2013, showed values of 3 and 9, respectively, for the two periods. Soil water storage was reduced by all cover crop treatments, with the greatest deficiency occurring during the extremely dry year of 2012. Previous studies have shown cover crop growth reduced by soil water depletion during their growing season and negative effects on early-season growth and development of subsequent cash crops such as silage maize, but if rainfall is extremely low it can also reduce cash crop yield. This detrimental effect of cover crops on soil water balance was confirmed by correlations between soil water storage and maize silage yield.Atmosphere 2018, 9, 492 2 of 18 precipitation [8], which is more likely to be mitigated on fertile and well-structured soils. The level of soil organic matter, and therefore soil carbon content, positively influence the stability of soil aggregates and soil moisture retention under extreme precipitation or drought [9][10][11]. Several management practices can be the bond between the requirements to adapt to the weather changes and to stop the reduction or to increase soil fertility, such as by reducing or eliminating tillage, growing cover crops, and applying organic fertilisers.Because livestock production in Serbia and, therefore, the availability of organic fertilisers are low, research focuses on cover cropping. Additionally, reduced or no tillage is uncommon because of requirements for adequate machines, which significantly limit its application on small and medium farms. Cover crops have several uses, including preventing erosion, increasing organic matter content, improving nitrogen balance and soil properties, and suppressing weeds, among others [12,13]. Cover crops in crop rotations are not a common practice primarily because growing cover crops usually includes crops that do not result in economic return and often do not allow sufficient time for soil preparation for cash crops. Additionally, cover crops may reduce soil moisture for the subsequent crop in specifi...

Microbially mediated soil organic matter is an extremely sensitive pool that indicates subtle changes in the quality parameters responsible for the soil’s ecological and productive functions. Fifty years of mineral fertilization of a wheat-corn cropping system has a strong impact on soil quality parameters. The goal of the research was to study the dynamics and quality of soil biological parameters affected by increasing amounts of mineral nitrogen. Soil respiration, potentially mineralizable C and N, microbial biomass C and N and light-fraction OM on Cambisol were analyzed in the following treatments: (1) Control (without fertilization); (2) NPK (60/51/67); (3) NPK (90/51/67); (4) NPK (120/51/67); (5) NPK (150/51/67 kg ha−1). The parameters studied were significantly affected by the long-term application of mineral fertilizer compared with both the control and the adjacent native soil. The highest amounts of nitrogen (N150) did not significantly differ from N120 and N90 for most of the parameters studied. Potentially mineralizable C represented the largest labile carbon pool, while microbial biomass N was the largest labile nitrogen pool. The mineralization rates for C and N were oppositely distributed over the seasons. The sensitivity index correlated with the amount of light-fraction OM. The results give a deeper insight into the behavior and distribution of different pools of labile SOM in the agro-landscapes and can serve as a reliable basis for further research focused on zero soil degradation.

“…This coincides with the state of the arable land-use systems in the Pannonian Plain, where significant changes in soil properties have been reported (soil organic matter loss, deterioration of physical and biological properties, salinization, etc.) [5][6][7]. An additional concern arises from the limited use of manure, which is attributed to decreased livestock numbers [8] and narrow crop rotations.…”

Maize is the most widespread and, along with wheat, the most important staple crop in the Republic of Serbia, which is of great significance for ensuring national food security. With the increasing demand for food and forage, intensive agricultural practices have been adopted in the maize production systems. In this direction, considerable research efforts have been made to examine the effects of different types of cover crops as a green manure on maize productivity; however, no consistent conclusions have been reached so far. Therefore, the objective of the present study is to examine the possibility of predicting the effects of winter cover crops (CC) integrated with different management practices on the morphological traits, yield, and yield components of maize. The experiment was carried out on chernozem soil from 2016 to 2020 as a randomized complete block design arranged as a split-split-plot with three replicates. The pea as a sole crop (P) and the mixture of pea and triticale (PT) are sown as winter CC with the following subplots: (i) CC used as green manure, and (ii) CC used as forage and removed before maize sowing. The artificial neural network is used for exploring nonlinear functions of the tested parameters and 13 categorical input variables for modeling according to the following factors: CC, way of using CC, N fertilization, and year. The computed maximums of plant height, number of leaves, number of internodes, plant density, number of ears, grain yield, 1000-grain weight, hectolitre weight, dry matter harvest residue, harvest index, leaves percentage, stems percentage, and ears percentage are as follows: 232.3 cm; 9.7; 10.2; 54,340 plants ha−1; 0.9; 9.8 t ha−1; 272.4 g; 67.0 kg HL−1; 9.2 t ha−1; 0.52; 18.9%; 36.0%, and 45.1%, respectively. The optimal result is obtained with peas used as green manure, with 50 kg N ha−1 and in the climatic conditions of 2018. Consequently, maize production under subsequent sowing periods can be successfully optimized by adapting selected management options for higher yield accomplishment.
