“…Both initial sieving conditions resulted in greater C concentration of macroaggregates compared with microaggregates ( p < 0.001). Greater soil organic C concentration in water‐stable macroaggregates than in water‐stable microaggregates is consistent with investigations in some tropical studies (Carmeis Filho et al., 2018; Sarker et al., 2018), but not in others (Madari et al., 2005). In this latter study with 19 mm initial screen size, macroaggregate C concentration was lower than microaggregate C concentration under native forest, but similar between aggregate fractions under conventional‐till and no‐till cropland.…”

Soil aggregation is considered a key indicator of soil health to protect soil against erosion, enhance organic C storage, and offer habitat for soil organisms. Various methods to assess aggregation may change interpretations of management, and therefore should be cross‐calibrated. We assessed the impact of initial sieve opening size (8 or 4.75 mm) prior to determination of dry‐stable and water‐stable mean‐weight diameter (MWD) from two fine‐textured soils—a Rhodic Hapludox from São Paulo, Brazil and a Rhodic Kanhapludult from North Carolina, United States. Both soils were subjected to management expected to alter surface soil conditions. As expected, initial sieving through 8 mm led to greater dry‐stable MWD (3.37 ± 0.60 mm) than initial sieving through 4.75 mm (1.94 ± 0.28 mm). However, soil stability index (water‐stable MWD/dry‐stable MWD) was not affected by initial sieve size opening (0.56 ± 0.13 mm mm−1 under both initial sieve openings). Management interpretations were consistent with both approaches as well, and in particular to detect the strong depth effect on water‐stable MWD (i.e., declining with depth). Water‐stable macroaggregates had 32% ± 25% greater C concentration than microaggregates; similarly under both initial sieving conditions. Soil stability index when initially sieved through 4.75 mm was highly associated with aggregate stability of 1–2‐mm sized dry aggregates, which is a more common procedure. We conclude that passing soil through a screen with 4.75‐mm openings to conduct a diversity of soil analyses can be appropriate for obtaining reasonable estimates of and interpretations about surface soil aggregation.

“…Even though the experience of Coventry et al () and Carmeis et al () suggested that liming could increase enhancing infiltration when the soil is ripped, Table indicates that the 2014 seasonal runoff for the limed plots of Transect‐1 ranked highest of the three transects. The opposite was true in the previous 2 years where the plot with conventional tillage and no liming in Transect‐1 ranked lowest in runoff among transects (Figure S1).…”

“…Moreover, studies in the Australian soils have shown that application of lime increases benefits from deep ripping of acidic soils (Coventry, Reeves, Brooke, Ellington, & Slattery, 1987). Liming was found to increase aggregate stability as reported by Carmeis, Crusciol, Guimaraes, Calonego, and da Costa (2018); aggregation decreased the amount of raindrop splash and prevent hardpan formation after it has been ripped. However, other studies have shown that clay dispersion increases by liming when surface applied or incorporated in the soil (Nunes et al, 2017).…”

Can degraded soils be improved by ripping through the hardpan and liming? A field experiment in the humid Ethiopian Highlands

Land degradation in developing countries is exacerbating hardpan development that causes the formation of perched watertable, which in turn results in increased runoff and erosion. To reduce overland flow and erosion, percolation through the hardpan needs to be improved. One successful way to achieve this is ripping off the hardpan and plausibly liming. However, in the highlands of Ethiopia, there is little information available on these two techniques. The objectives of this study were, therefore, to determine the effects of ripping off degraded soils on runoff and erosion rates and whether liming would improve the effectiveness of ripping. A field study was conducted in the Anjeni watershed. Thirty‐two experimental runoff plots were installed across the watershed. Conventional tillage at 15 cm depth and ripping to 30, 45, and 60 cm depths were applied with and without lime amendments. Results showed that ripping to 60 cm depth resulted in a significant reduction of runoff. However, liming increased runoff response, on average by 10%. In contrast to the reduction in runoff amounts, an increase in ripping depth increased the amount of soil loss especially during the first storms at the beginning of the monsoon rainy season. Liming significantly decreased soil loss by up to 35%. Although plots with deep ripping plus liming had greater runoff production than other plots, soil loss was less. Overall, the findings suggest that deep ripping has promise but more research is needed before widely implemented.

“…The surface liming under a no-till system improves soil aggregation by increasing the average aggregate diameter in the layer (0-0.01 m), but without the same effect on the layer (0.02-0.1 m) (Ferreira et al, 2019). Carmeis et al, (2018) the superficial liming in the no-till system increased the amount of soil macroaggregates at a depth of 0-0.4 m, but the effect magnitude varied according to the applied limestone dose and soil depth. Further, the increase in average aggregate diameter shows a positive correlation according to the increase in applied limestone doses.…”

Soil acidity is a major constraint to crop production globally by potentially limiting agricultural productivity and causing environmental challenges, especially in temperate and tropical regions of the world where there is high precipitation. The review article summarizes the works of literature and gathers information on the effects of liming on soil's physicochemical properties and the yield of crops. Soil acidity is caused by natural ways, such as the high amount of precipitation that exceeds evapotranspiration that leaches appreciable amounts of exchangeable bases from the soil surface, weathering, and decomposition of organic matter and by human interference (by the use of nitrogen fertilizer mainly ammonia and urea fertilizers). Application of lime improved soil pH and neutralize the effect of toxic elements. Liming directly improves some physicochemical properties of the soil, such as aggregates, density, and porosity as physical properties and reduction of exchangeable acidity, Al saturation, micronutrients (Cu, Fe, Mn, and Zn) in the soil solutions, from exchange complex to the levels required and increasing soil pH, exchangeable cations (Na+, K+, Ca+2, and Mg+2) as chemical properties. Soil aggregation, density, and porosity of soil undergo changes with the application of lime. The long-term lime application resulted in increased soil chemical properties. Lime application contributed to increased crop productivity and crop quality. The effects of liming can be explained by the flocculation and cementing action of Calcium ions in the short term. In the long term, increases in productivity induced by liming, result in increasing soil pH, available phosphorus, cation exchange capacity, basic cations, microbial activity, organic carbon, total nitrogen, and decreasing leaching of nutrients, exchangeable aluminum, and acidity, all favoring the physical and chemical properties of the soil.
