“…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.…”

“…In contrast, Salem et al (2015) attributed soil compaction and a potential reduction in maize yield to the tillage method, although the greatest bulk density reduction was observed under conventional tillage and measured cone index was the largest in zero tillage. Wilkins et al (2002) also reported that a short-term no-tilled soil had higher soil strengths than tilled ones.…”

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.

“…This indicates that such an in situ sequestration technology is not only effective towards SOC sequestration, but it also conserves the full plant nutrition capacity of soil and its potential crop productivity. Conversely, the NT and RT practices, aimed to increase carbon sequestration by reducing the bio‐oxidation of SOM, are reported to limit the mineralization of plant nutrients in soils and result in lower crop yields (Pittelkow, ; Salem, Valero Ubierna, Muñoz‐García, Gil Rodríguez, & Silva, ; Zavattaro et al, ).…”

Effective carbon sequestration in Italian agricultural soils by in situ polymerization of soil organic matter under biomimetic photocatalysis

et al. 2018

Facing an exploding population growth with consequent increase of agriculture intensification, new chemical technologies are being sought to limit organic matter losses and reduce land degradation. Here, we report that an effective organic carbon sequestration in different cropped soils of Italy is obtained by an in situ photo‐oxidative coupling among soil humic molecules, when catalyzed under solar irradiation by a water‐soluble biomimetic iron‐porphyrin catalyst amended to field soils. A 3‐year long field study showed that the catalyst‐assisted in situ photochemical polymerization of humic matter enabled a yearly sequestration of soil organic carbon that ranged from 2.2 to 3.9 t ha−1 y−1, despite the periodical soil disturbance due to a conventional tillage management. This significant stabilization of organic matter was observed not only in bulk soils but also in water‐stable aggregates, whose loss of organic carbon during separation was limited in catalyst‐treated soils. Although crop yields were the same in treated and control soils, measurements of phospholipids fatty acids and soil enzyme activities indicated that the catalyzed in situ photo‐oxidative coupling of humic molecules did not alter the structure and activity of microbial communities and the biological functions of soils. This innovative and ecologically safe catalytic technology may be developed as a useful soil management practice to stabilize organic matter in situ in arable soils, while concomitantly ensuring soil functions and sustainability of crop production.

“…In addition to biochar application, the retention of crop residues on soils can serve as physical barriers to reduce soil erosion and concurrent N related losses. Thus, adoption of reduced tillage could save input costs while improving long-term sustainability of the soil for crop growth (Licht and Al-kaisi, 2005;Gürsoy et al, 2010;Salem et al, 2015). More importantly, conventional tillage increases operational cost while disrupting the structure and other important properties of the soil (Shahzad et al, 2017).…”

Tillage and Biochar Effects on Wheat Productivity under Arid Conditions

Urea is an important source of inorganic N under wheat (Triticum aestivum L.) production system in Multan, Pakistan. However, the average N loss is high, ranging from 22 to 53% of applied N, which poses adverse environmental impacts. Reduced tillage and combined application of biochar and optimal N fertilizer could improve wheat productivity and reduce N losses. We evaluated the effects of two tillage (conventional and reduced tillage), two biochar (no biochar and poultry waste biochar), and three inorganic N rate (0, 60, and 120 kg ha−1) treatments on productivity and economic profitability of wheat production for two continuous growing seasons (2014–2015 and 2015–2016). Generally, reduced tillage increased wheat grain yield, protein content, and total N uptake by 0.2 Mg ha−1, 3.0 kg kg−1, and 37.0 kg ha−1, respectively, when compared with conventional tillage. Biochar application increased wheat grain yield, protein content, and total N uptake by 0.3 Mg ha−1, 6.8 kg kg−1, and 38.6 kg ha−1, respectively, compared with no‐biochar plots. Reduced tillage was economically profitable within the two cropping seasons, but biochar application was not, because of the high price of biochar (US$1.00 kg−1 biochar) and application rate (10 Mg biochar ha−1). Overall, wheat production under reduced tillage, no biochar, and the 60‐kg N ha−1 rate resulted in the greatest economic profit in this study.
