“…The soil chemical properties prior to the experiment are described in Table 1. According to Sousa et al (2016), the mean levels of nutrients were close to those considered adequate to maintain high crop yields.…”

“…In some studies, the low response of soybean to phosphorus fertilization in soils with adequate levels or high availability of phosphorus (P) has been documented (Lacerda, Resende, Furtini Neto, Hickmann, & Conceição, 2015). Thus, in these situations, flexibility in the management of phosphate fertilization could be considered (Lacerda et al, 2015;Nunes, Sousa, Goedert, & Vivaldi, 2011;Pavinato & Ceretta, 2004;Prochnow et al, 2017;Resende et al, 2006;Santos et al, 2012;Sousa, Nunes, Rein, & Santos Júnior, 2016), and the application can be made only to replace the quantities of the nutrient exported by the crops.…”

In soils with adequate levels of fertility, it is possible to manage phosphate fertilization aiming at the grain production system, instead of each isolated crop. The objective was to evaluate the effects of the management of phosphate fertilization, place and time, on the soil and leaf P content, and crop yield in grain production systems. An experiment was conducted at the farm level in the municipality of Nazareno, state of Minas Gerais, Brazil, for four years on soil with adequate level of fertility. The treatments consisted of the management of phosphate fertilization by broadcast or furrow and dose for each crop or for the production system (spring/summer and autumn/winter crops), being: Control = without phosphate fertilization; Conventional = phosphate fertilization in the furrow in each crop; BTP = phosphate fertilization of the grain production system to broadcast; TPS = phosphate fertilization of the grain production system in the furrow of the spring/summer crop; TPW = phosphate fertilization of the grain production system in the furrow of the autumn/winter crop. Soil P content was evaluated in the third year of implantation, and the crops yield every season crop (maize, soybean, common bean and wheat). The P content in the leaves of maize and soybeans were evaluated in the spring/summer crops. The application of the total dose of phosphate fertilization for both crops in the sowing furrow of the spring/summer or autumn/winter crops (TPS and TPW) promoted operational advantages and increased soil P content in the 0-0.20 m layer, without reducing the yield of the spring/summer crops. Leaf P content was not affected. The Conventional management (phosphate fertilization in the furrow in each crop) provide greater yield of common beans and wheat during autumn/winter crops, which are more subject to water restriction due to less rainfall, even without increasing the soil P content.

“…Miconia ibaguensis and C. brasiliense are frequent species of flooded gallery soils (Sano et al, 2008), presenting one of the lowest survival rates. As this situation does not occur in the experiment area, this characteristic may have led to the lower survival rates of these species, consequently placing them in the group with the averages of listed biotic factors.…”

Establishment of native seedlings species as an indicator of ecological restoration of riparian forest, Cerrado, DF, Brazil

et al. 2023

This study evaluated the survival of seedlings of native species of Cerrado - Brazil and its potential as an indicator of ecological restoration of riparian forests. The factors affecting survival were also analyzed. The experiment consisted of three planting models with three replications (T1 = nucleation: Anderson model; T2 = nucleation: Anderson model + artificial perches; T3 = filling line and diversity line). The influence of factors such as leaf herbivory, stem herbivory, absence of leaves (predation, dehydration or malnutrition) and sprouting/regrowth survival were assessed by cluster analysis. The survival rates ranged from 58.6 to 100% (average 73.6%). Out of eighteen species, fifteen showed survival rate above 60%, and could be potentially used in the restoration of degraded areas. The hierarchical clustering using survival efficiency and biotic factors resulted in the distinction of two groups of species with high frequency of leaves and stem herbivory, differing statistically (test “t”, p < 0.05) in the sprouting and regrowth. The survival efficiency shows potential of being used as a restoration indicator.

“…Os autores relatam que a massa de grãos por espiga e a produtividade responderam apenas as doses de nitrogênio, não sendo afetadas pelas doses de potássio. É importante destacar, que na presente situação, os teores naturais de K no solo eram de aproximadamente 140 mg dm -3 , valor muito superior ao considerado adequado conforme Sousa e Lobato (2004).…”
