“…The standardized mean values showed a trend in the areas of higher levels of Al, which also presented lower Ca and pH levels and, consequently, lower eucalyptus heights. These data agree with those found by Oliveira et al (2017), who evaluated the chemical characteristics of an Entisol soil in the Cerrado under different uses and covered with tree species and found that the higher the Al content in the soil, the lower the pH, resulting in a lower development of tree species.…”

The purpose of this study was to identify, through multivariate analyzes, the physical and chemical characteristics of the soil that best explain the initial development of eucalyptus treated with limestone and lime sludge. This study was conducted in 2014 in the municipality of Três Lagoas (MS). Three treatments were experimented corresponding to the applications of (i) limestone, (ii) lime sludge, and (iii) control or application of neither limestone nor lime sludge. The principal components analysis identified that Group 1 assembling gravimetric moisture, hydrogen potential, calcium and aluminum and, Group 2 composed of contents of sand, clay, phosphorus and organic matter explained 54.96% of the total variability that showed higher discriminatory power of eucalyptus height and diameter variation at breast height. The treatment with limestone showed a contrast between high pH and high Ca content, but low levels of aluminum.

“…The most marked difference was obtained as a function of the phosphorus level obtained by Roque, Prado, Natale, Beutler and Centurion (2004), who also evaluated coffee under a Red-Yellow Argisol in the Cerrado region. Oliveira, Ensinas, Barbosa, Nanzer and Barreta (2017) found levels of P, K, Ca, and Mg of 3.82 mg dm −3 , 175.91 mg dm −3 , 1.10 mmol c dm −3 , and 0.80 mmol c dm −3 , respectively, in a single rubber tree system under a Quartzarenic Neosol, being similar to the results found in the present study due to similar environment conditions.…”

Rubber tree (Hevea brasiliensis) is a native species of the Amazon biome. This species had great economic importance due to the production of latex, used to obtain natural rubber. Seeking growth in productivity with adequate management is necessary to optimize production and increase areas with rubber trees. This study aimed to verify the physical and chemical attributes of soil under three different managements and two rubber tree clones, searching for the best alternative for the general edaphoclimatic conditions of the Cerrado biome. The experiment was installed in Palmeiras of Goiás, GO, Brazil, in a randomized block design in a 2×3 factorial arrangement, consisting of two rubber tree clones (PB 312 and RRIM 600) and three management strategies (organomineral fertilizer with poultry litter, pigeon pea as green manure, and mechanical mowing-brushcutter). Physical attributes such as soil density, soil penetration resistance, soil moisture and aggregation, soil fertility, and tree development were analyzed. Statistical analyses of variance and Tukey test were carried out in order to compare the dendrometric data and physical and chemical attributes of the soil under the different treatments applied in the inter-row of rubber trees. No significant statistical differences were found among treatments and between clones in relation to soil physical attributes. However, the soil pH reduced the use of organomineral fertilizer and the clone RRIM 600 had the highest heights.

“…The main factors and causes of this low soil fertility, which affects B and Zn availability, are: soil pH (the higher the soil acidity, the lower the B availability to plants); soil texture (low availability of nutrients in sandy soils); low soil moisture maintenance capacity; low soil organic matter contents (mainly sandy soils); leaching (low soil water retention capacity); high phosphorus (P) rates (high P concentrations may result in Zn deficiency); application of products to correct soil acidity; and exports of nutrients through harvests (NOGUEIRA, 2016;OLIVEIRA et al, 2017).…”

The objective of this work was to evaluate the effect of soil application of different boron (B) rates to the soil, with and without application of zinc (Zn), on growth, production components, and grain yield of maize crops grown in a Lithic Quartzipsamment with low B and Zn contents. A randomized block experimental design was used, in a 6×2 factorial arrangement corresponding to six B rates (0, 1, 2, 3, 4, and 5 kg ha-1), with and without application of Zn (2.0 kg ha-1), applied to the soil at sowing, with four replications. Growth variables (stem diameter and plant height), and chlorophyll SPAD index were evaluated at the R1 phenological stage. Maize ear length, one-thousand grain weight, and grain yield, and the B maximum efficiency rate were evaluated at the R6 phenological stage. Application of B and Zn to the soil increases maize grain yield in soils with sandy clay loam texture and low B and Zn contents; the plant absorption and metabolism indicated synergism between these elements when using soil applications of 1.0 kg ha-1 of B combined with 2.0 kg ha-1 of Zn to the planting furrows. The rates with maximum technical efficiency for grain yield were 3.29 and 4.31 kg of B ha-1 in treatments without and with application of Zn, respectively.
