“…Averaged across tillage and study period, soil pH was influenced by N rate where soil pH was lower by 1% (0.09 unit) with high N and by 0.6% (0.04 unit) with low N rate compared with the control treatment (figure 3a). Similarly, previous research reported a reduction in soil pH with increasing N rates (Mikha et al 2006;Fageria et al 2010;Das et al 2012;Villamil and Nafziger 2015;Conceição de Sousa et al 2017;Moinoddini et al 2017). Throughout the 10 years of the study period, the reduction in soil pH associated with organic amendments or commercial fertilizer addition was likely related to the acidification effects resulting from manure decomposition and commercial fertilizer N nitrification (Chang et al 1991;Bolan and Hedley 2003;Villamil and Nafziger 2015;Conceição de Sousa et al 2017).…”

Land application of beef cattle (Bos turus) manure is a management strategy that can supply essential plant nutrients, enhance land sustainability, and maintain environmental quality. The objectives of this study were to evaluate (1) soil chemical properties and (2) temporal changes in soil nutrient dynamics as influenced by tillage practices (no-tillage [NT] and conventional tillage [CT]) and nitrogen (N) sources (manure and commercial fertilizer; urea) at two application rates (high 134 kg N ha-1 y-1 [120 lb ac-1 yr-1 ] and low 67 kg N ha-1 y-1 [60 lb ac-1 yr-1 ]) for both N sources. An unfertilized control treatment with no N added was also included within each tillage treatment. The study was conducted on an Armo silt loam (fine-loamy, mixed, mesic Entic Haplustolls) at Kansas State University Agriculture Research Center near Hays, Kansas, from 2006 to 2016. Soil samples were taken annually at 0 to 15 cm (0 to 6 in) depth prior to spring field operations. Across tillage, soil pH, total N (TN), extractable phosphorus (P), potassium (K), and sodium (Na) were influenced by N source, N rate, and sampling time. The high manure rate treatments increased soil TN by an average of 19% compared with the commercial N fertilizer and control treatments. Eliminating tillage enhanced soil TN accumulation in the top 15 cm of soil by approximately 9% more than CT. Extractable soil P measured in 2016 increased by approximately 401% compared with 2006. Similarly, soil P increased by approximately 331% with high manure and by 66% with low manure compared with commercial fertilizer treatments. Manure addition at high and low rates had 43% and 20% increase in soil available K, respectively, compared with commercial fertilizer treatments. The observed temporal variability in soil extractable P, K, and Na were mostly related to manure addition. The increase in N rates strengthens the relationship between soil electrical conductivity (EC) and soil nitrates (NO 3), especially with commercial fertilizer where the changes in soil EC were 2.8-fold greater than the manure treatments. The significant (p < 0.05) changes in soil chemical properties influenced by the management interaction throughout the years (time × tillage × N sources) may take longer than 10 years to be observed in the dryland cropping system of the Great Plains region. However, growers should take extra care to prevent soil P and Na accumulation, specifically when cattle manure is being added to meet the N requirement for crop production.

“…According to [54], the tillage system has no appreciable short-term impact on soil EC. At deeper soil layers (5-15 and 15-30 cm), EC levels were not significantly affected by the tillage system [55].…”

“…Wheat and cowpea grain yields were significantly affected by the interaction between tillage and soil additive rates (p ≤ 0.05). According to [55], the highest grain production was obtained using a minimum tillage system with the application of 250 kg of nitrogen per hectare, which is 38% more nitrogen than a conventional tillage system requires at the same rate. Therefore, better understanding of the interactions between specific cropping systems and other crop management practices, their resulting changes in soil microbial ecology, and their roles and effects on crop health and productivity is required for the creation of more efficient and sustainable crop production systems.…”

Tillage systems comprise physical, chemical, and biological modification processes that influence soil properties. Soil cultivation aims to create favorable conditions for the development and growth of crops, as evident in their yields. Three growing seasons (winter 2019/2020 (wheat), summer 2020 (cowpea), and winter 2020/2021 (wheat)) were studied in field experiments in Sidi Salem, Kafr El-Sheikh, Egypt, to investigate the effects of soil tillage and the application of organic and beneficial microbes on various biological, chemical, and physical properties of soil and its productivity. Three replicates of the experimental treatments were set up in a split-plot design, in which there were four main plots: conventional soil tillage (ST) treatment for all three seasons (ST1); tillage in the first and second seasons (ST2); tillage only in the first season (ST3); and no tillage for all three seasons (ST4). However, the subplots (soil additives) were conditioned as follows: without treatment (control, T1); compost (C, T2); beneficial microorganisms (BM, T3); and combination (C + BM, T4). The biological property results showed that ST4T4 treatment produced high levels of microbial communities (bacteria, fungi, and actinomycetes), as well as high levels of soil enzyme activity (dehydrogenase, urease, and phosphatase), during the three growing seasons. However, the second season produced high numbers and dry weights of cowpea plants’ nodules. Additionally, changes in the chemical and physical properties showed that the application of various soil tillage treatments during the examined seasons led to significant increases in electrical conductivity (ECe, dSm−1), bulk density (BD, kg m−3), and soil infiltration rate (IR, cm h−1), following the trend of ST4 > ST3 > ST2 > ST1. In contrast, the results revealed decreases in the exchangeable sodium percentage (ESP, %), porosity (PO, %), soil aggregates (stable aggregates and optimal-sized aggregates, %), and soil penetration resistance (SPRa, Mpa). The combination treatment (ST4T4) provided the best yields, with grain yields of 4.991 and 5.325 tons ha−1 and straw yields of 5.214 and 5.338 tons ha−1 in the first and third seasons (wheat), respectively. Cowpea plants showed the same pattern in the second season. Therefore, improvements in soil properties and enhancements in biological activity help maintain its productivity and fertility through simplified tillage processes that reduce interference with the soil surface layer.
