“…The attributes regarding plant height and size were consistently high in the technical data of each genetic material (COODETEC, 2017). However, regions with a high incidence of wind blow can damage the cultivation of CD1104, as taller wheat plants are more prone to lodging which may lead to more losses in the harvest (Nascimento et al, 2016).…”

Agricultural practices that allow a productive increase in a sustainable manner are becoming increasingly necessary to feed an ever-growing global population. The inoculation with Azospirillum brasilense has the potential to reduce the use of synthetic mineral fertilizers with efficient capacity to promote plant growth and increase nutrition. Therefore, this research was developed to investigate the potential use of A. brasilense to increase the accumulation of macro- and micronutrients and its influence on grain yield, plant height, and spike population in two wheat cultivars (CD1104 and CD150), under irrigated conditions in the Brazilian Cerrado. The study was carried out in a Rhodic Hapludox under a no-tillage system. The experiment was designed in randomized blocks with six replications, arranged in a 2 × 2 factorial scheme: two cultivars (CD150 and CD1104) and two levels of inoculation (control and with A. brasilense). The inoculation with A. brasilense provided greater accumulation of micronutrients in the aerial part of the wheat. In the cultivar CD1104, B and Cu had an accumulation 27.7 and 57.4% higher compared with those of the control without bacteria. In the cultivar CD150, Azospirillum increased the accumulation of B, Fe, and Mn by 43.8, 49.9, and 22%, respectively, and reduced Cu by 21.9%, compared with those of the control. The cultivar CD150 has greater efficiency to accumulate N (+35.5 kg N ha−1) as compared with the cultivar CD1104. Interactions between inoculation and cultivars resulted in greater accumulation of S and K in the shoot of the wheat cultivar CD150, as well greater accumulation of Cu in CD1104. In growth assessments, inoculation or cultivars did not statistically influence wheat grain yield and spike population. Howevere, for plant height, the CD1104 genotype has 13.1% bigger plant height on average than that of the CD150 genotype. Inoculation can contribute more sustainably to wheat nutrition.

“…The NTS treatments consisted of two conditions of the soil surface: under no-tillage with and without mechanical chiseling -combined with four cover crops adapted to the Cerrado conditions (Santos et al, 2012;Nascimento et al, 2016). In 2012, after 15 years of no-tillage, treatments were implemented to study the effects on soil quality, with mechanical chiseling of the area, sowing of cover crops and upland rice.…”

Soil compaction in no-tillage systems (NTS) affects the sustainability of this management. To overcome the problem, mechanical chiseling and maintenance of the vegetation cover suggested were as management practices in order toreestablish ideal cultivation conditions. The soil studied was occupied for 20 years with annual crops in conventional tillage system (plowing and leveling harrow). After, the NTS was implemented for 15 years old. In 2012, management were implemented to study the effects on soil quality, with mechanical chiseling, cover crops, rice and bean. Thepurpose of this study was to evaluate the effect of soil chiseling and the use of cover crops on the maintenance of NTS sustainability after a crop succession of rice and common bean on a clayed Orthic Ferralsol. After four years we evaluation were then carried out to analyze the effects of the system on the soil quality physical and chemical attributes. We studied five cover plants (Crotalaria juncea; Cajanus cajan; Pennisetum glaucum; Urochloa ruziziensis and Fallow) all in NTS with and without chiseling. In addition, we studied a natural Savannah fragment too. Chiseling with cultivation of Crotalaria juncea as vegetation cover improved the physical properties compared with the initial conditions. However, cover crops grown on unchiseled soil resulted in an increase in the chemical properties P, K, and Mg concentrations, pH, and soil organic matter. The soil nanostructures morphological characteristics is a promising indicator it quality, complementary to the chemical indicators, for being sensitive enough for the short-term detection of changes soil properties.

Fertilization of Eucalyptus Stands at Advanced Ages in Minas Gerais, Brazil

et al. 2019

This study evaluated the response to fertilization at advanced ages in Eucalyptus stands. Fertilization at advanced ages (FA) was applied in stands managed according to tall shaft and coppice regimes. All stands received operational fertilization from the company. It was used as the basis to the network of continuous forestry inventory plots (P-IFC) of the company. Connected to the P-IFC, twin-plots received FA throughout four age classes, 30 to 35, 42 to 47, 54 to 59 and 66 to 70 months. The FA presented a biological response and provided volumetric gains of 17 and 51% for stands with tall shaft and coppice, respectively. The most significant responses to the FA was seen at younger ages of the forest in the tall shaft regime. Despite the biological response, the volumetric gains did not provide financial returns in either regime due to the elevated doses applied.
