“…Furthermore, over the three growing seasons, conventional tillage trended to result in greater grain yield and grain N uptake compared with no‐tillage systems. Afzalinia and Zabihi () and Salem, Valero, Munoz, Rodriguez, and Silva () observed similar reductions in crop yields during the first year of implementation of the no‐tillage systems for a maize crop under Mediterranean conditions. Several reasons such as waterlogging, poor crop establishment, lower root development by compaction, nutrient deficiencies or time of implementation are pointed out as possible reasons, which would explain the worst crop performance under no‐tillage systems (Pittelkow et al., ).…”

Irrigation and soil management can impact soil nitrous oxide (N2O) emissions. Flood and sprinkler irrigation systems together with conventional tillage are the main practices used in the high yielding maize systems in Mediterranean Spain. The objective of this field work was to quantify the effect of the irrigation system (i.e., flood, F; and sprinkler, S) and the soil tillage system (i.e., conventional tillage, CT; no‐tillage maintaining the maize stover, NTr; and no‐tillage removing the maize stover, NT) on the N2O emissions from the soil during 3 yr (2015, 2016, and 2017). S irrigation, with mean values of 1.35 kg N2O‐N ha−1 yr−1 throughout the 3 yr, obtained 42% lower N2O emissions than F irrigation. On average of the three growing seasons, yield‐scaled N2O emissions by grain yield and by grain N uptake in F irrigation were two‐fold higher than in S irrigation. Moreover, in one out of three growing seasons (2017), no‐tillage systems (i.e., NTr and NT) showed greater yield‐scaled N2O emissions compared with CT. The higher maize grain yield with the S irrigation compared to F irrigation, as well as the lower N2O emissions reported under S irrigation resulted in the reduction of the yield‐scaled N2O emissions. Our findings highlight the role of sprinkler irrigation decreasing N2O emissions in comparison to flood irrigation in Mediterranean agroecosystems.

In addition to various positive aspects, long‐term reduced tillage may cause disadvantages such as increased weed pressure and soil compaction. Thus, single inversion tillage is customarily used for overcoming these drawbacks; however, the effects on the enhanced soil functions are unknown. The main objective of this study was therefore to assess whether improved soil physical properties following long‐term reduced tillage remain after one‐time inversion tillage by mouldboard plough. The study was undertaken on a silt loam field in Lower Saxony, Germany. Since 1996, this field has been subdivided into three treatments; one was managed conventionally using a mouldboard plough (CT), while on the others a chisel plough (RT1) and a disc harrow (RT2) were employed. In October 2014, the entire field was mouldboard ploughed. The following year, four field campaigns were conducted to compare the soil physical properties of the continuously conventional tilled plot with those affected by one‐time inversion tillage (RT1 and RT2). Dry bulk density (DBD), saturated hydraulic conductivity (Ks) and infiltration rate [K(h)] were analysed in untrafficked and trafficked areas in each plot. There were clear differences between CT and RT. At all sampling dates, both RT plots had higher Ks and K(h) compared with CT. These differences also occurred to some extent on the trafficked areas. This suggests that improved soil hydraulic properties remained after one‐time inversion tillage of a long‐term reduced tilled field. Thus, one‐time inversion tillage may offer a suitable measure for overcoming some of the main disadvantages associated with long‐term reduced tillage, while preserving the positive effects on soil physical properties.

“…He et al (2014) calculated 40% cereal yield reductions: the simulated yields of wheat were very sensitive because of soil texture. Afzalinia and Zabihi (2014) raised the problem of when to carry out the soil physical measurements. The measurements must be carried out under soil circumstances characterized by growing conditions of cereals.…”

“…Furthermore, a functional relationship was determined between soil compaction and moisture values at the same bulk density values for loam textured soil which could convert resistance values at the same moisture content. Afzalinia and Zabihi (2014) concluded that the penetration measurements do not give adequate opportunity to set up connections while the measurements at the end of the growing season provide more accurate values. Karmakar and Kushwaha (2007) examined the gravimetric soil moisture content (10%, 13%, 17% and 20% dry basis) on clay loam soil (29% clay, 24% silt and 47% sand) on five soil compaction levels (100, 150, 200, 300 and 400 kPa).…”

“…But they also suggest that these methods caused minimal impact on maize production and have no effect on the tested N-treatments concerning the treatment time. Afzalinia and Zabihi (2014) concluded that between the cone index and tillage systems there are significant correlations in maize growing seasons. Salem et al (2015) also came to this conclusion, measuring the highest maize yield, the longest kernel and the highest thousand-kernel weight in the conventional tillage sytem.…”

This paper reviews the works related to the effect of soil compaction on cereal yield and focuses on research of field experiments. The reasons for compaction formation are usually a combination of several types of interactions. Therefore one of the most researched topics all over the world is the changes in the soil's physical and chemical properties to achieve sustainable cereal production conditions. Whether we are talking about soil bulk density, physical soil properties, water conductivity or electrical conductivity, or based on the results of measurements of on-line or point of soil sampling resistance testing, the fact is more and more information is at our disposal to find answers to the challenges.Thanks to precision plant production technologies (PA) these challenges can be overcome in a much more efficient way than earlier as instruments are available (geospatial technologies such as GIS, remote sensing, GPS with integrated sensors and steering systems; plant physiological models, such Decision Support System for Agrotechnology Transfer (DSSAT), which includes models for cereals etc.). The tests were carried out first of all on alteration clay and sand content in loam, sandy loam and silt loam soils. In the study we examined especially the change in natural soil compaction conditions and its effect on cereal yields.Both the literature and our own investigations have shown that the soil moisture content changes have the opposite effect in natural compaction in clay and sand content related to cereal yield. These skills would contribute to the spreading of environmental, sustainable fertilizing devoid of nitrate leaching planning and cereal yield prediction within the framework of the PA to eliminate seasonal effects.
