“…Tukey test at t Oliveira,[29], also found high MRP values from the 250 mm layer, which probably is due to the textural gradient by the beginning of the textural B horizon, providing lower permeability of the B horizon due to the increase of the clay fraction. In this condition, with low humidity leads to a lower lubricating effect of the water around the soil particles and, consequently, to higher values of MRP.…”

Conservation systems for less soil movement and when associated with previous crops may reduce the effects of soil compaction. The objective of this work was to evaluate soil mechanical resistance penetration (MRP) in different cropping systems associated with previous corn crop after fifteen years. The experimental design was composed of experimental strips with subdivided plots, combining three soils management systems: CC- conventional cultivation, MC- minimum cultivation and NT- no-tillage, and four species of crops antecedent to maize for the production of commercial ears of green corn. In the determination of soil MRP, the electronic penetrometer (FALKER model SoloTrack PLG 5200) was used, with readings up to a depth of 400 mm. The results showed that there was a significant effect on the MRP values of the soil when submitted to the different cropping systems and previous crops at the end of fifteen years. The lowest MRP values were located in the superficial layers in the CC and MC. The NT cultivar system showed higher MRP values, at depth 0-100 mm. At conditions of tableland, after fifteen years, it was observed that the NT system provides better corn productivity levels combined with lower MRP values along the profile.

“…According to Köppen, the climate is classified as, tropical rainy, with an average annual temperature of 25.2°C (dry summer) and precipitation of 1,300 mm, mostly from April to September (Santos et al, 2009). The soil of the experimental area is classified as an Argissolo Vermelho-Amarelo (Santos et al, 2018), i.e., an Ultisol according to Soil Taxonomy (Soil Survey Staff, 1999), which is typical of the Brazilian coastal plains (Oliveira et al, 2017), showing the following chemical properties: pH (H 2 O) 5.49, 18.04 mg L -1 P, 82.20 mg dm -3 K, 2.00 cmol c kg -1 Ca, 1.00 cmol c kg -1 Mg, 2.54 cmol c kg -1 H+Al, base saturation of 45.43%, cation exchange capacity at pH 7.0 of 6.45 cmol c dm -3 , and 2.67 dag kg -1 organic matter.…”

The objective of this work was to evaluate the effect of the application of calcium oxide (CaO) particle film on the physiological performance, bromatological quality, and productivity of sweet potato (Ipomoea batatas). The experimental design was randomized complete blocks with three treatments (5, 10, and 15% CaO particle film concentrations) and a control (water), with three replicates, applied 30 days after planting. The following parameters were evaluated: physiological, including net photosynthetic rate and Falker chlorophyll index (FCI); bromatological, i.e., crude protein, neutral detergent fiber (NDF), acid detergent fiber (ADF), total digestible nutrients (TDN), dry matter digestibility (DMD), and total carbohydrates; and productivity. The use of the 10 and 15% CaO particle film increased sweet potato photosynthesis, FCI, crude protein content, and tuber and aerial part productivity. At those concentrations, the lowest NDF and ADF contents and the highest TDN and DMD contents were also observed. The use of the CaO particle film at the concentration of 10 and 15% improves the physiological, productivity, and bromatological parameters of the sweet potato crop.

“…The experiment was carried out in an experimental area of the Experimental Station of the Federal University of Sergipe, located in the Poxim river basin (Figure 1), in the city of São Cristovão -SE, whose geographic coordinates of Greenwich are 10° 9236′S for latitude and 37°1993′W for longitude (OLIVEIRA et al, 2017), the soil is classified as Ultisol (SANTOS et al, 2018). The region has a rainy climate with dry summer and an average rainfall of 1200 mm per year, with rainfall concentrated in the months of April to September.…”

The present work had an objective to compare the stable infiltration rate obtained by infiltrometers with reduced dimensions and varied forms in different land uses. The infiltration tests were carried out in areas planted with cowpea, crotalaria, pigeon pea and millet, as crops previous corn planting, and managed with no-tillage, minimum tillage and conventional tillage and native forest area. In order to compare and analyze the results of the stable infiltration rates obtained between the alternative infiltrometers and the considered standard, the criteria involving the standard error of estimation (EPE), the standard error of estimation adjusted (EPEa), the standard error of estimation adjusted by origin (EPEao) and coefficients of adjustments of the linear equations with their respective determination coefficients (R2) were used. It was verified that the double-ring reduced, single-ring and double square infiltrometers provided a water saving of 57.06%, 66.19% and 38.54% respectively, relative to the standard. The alternative infiltrometers overestimated the stable infiltration rate in relation to the standard. The single-ring infiltrometer obtained a stable infiltration rate correction equation that showed results very close to the standard and the best statistical indices of stable infiltration rate results were obtained by the reduced double-ring infiltrometer.
