(Universidade Federal de Goiás, 2017-02-23) Cardoso, Aline Assis; Leandro, Wilson Mozena; http://lattes.cnpq.br/9052207260053937; Brasil, Eliana Paula Fernandes; http://lattes.cnpq.br/7324619074753727; Brasil, Eliana Paula Fernandes; Borges, Jácomo Divino; Calil, Francine Neves; Ucker, Fernando Ernesto; Corcioli, Graciella
The formation of seedlings destined to the implantation of forest stands for the production of wood and mixed stands for the purpose of environmental preservation and/or recovery of degraded areas is related to the level of efficiency of the substrates. Organomineral fertilizer is feasible for both small and medium-sized producers as well as for large producers and rural entrepreneurs. In addition to the financial benefit from reduced costs, and the physical and biological benefit of soil, with the highest input of nutrients and organic matter, organomineral fertilization also has an environmental advantage. This fertilizer is produced from organic waste as crop residues and by-products from the industry. The general objective is to produce granular organomineral fertilizers with the use of an accelerator biocatalyst in order to be used in the production of seedlings of forest species, being evaluated their physical, chemical and biological attributes, measuring the phytotechnical aspects and nutrient concentration in the plants of forest species. The conduction was carried out in conventional system (polyethylene tubes) in comparison to the biodegradable tubes. The experiment was carried out in Goianira, GO. The research was carried out in three stages, the first one being the preparation of the agroindustrial residues to compose the mixtures and to generate the organomineral fertilizer. For the composition of the organic compounds, four types of agroindustrial residues were used: sugar cane bagasse, sugar cane filter cake, ashes, vinasse and decomposing microorganisms (use of biocatalyst). The second stage was the production of granulated organomineral fertilizer. The organic compounds (types I and II) produced in the first stage were naturally dried with the use of solar radiation to reduce humidity by 10% and subsequently received mechanical treatment through grinding/milling to produce a granulometric fraction in Powder form. The third step was the production of Acacia mangium, Khaia ivorensis and Eucalyptus grandis seedlings in greenhouse, and the experimental design was randomized blocks in factorial scheme 7 x 2, the means were compared statistically using statistical software SISVAR. The organic compound type I presents statistically superiority in the parameters organic matter, organic carbon and Carbon/Nitrogen ratio. Organic matter (OM) is formed of organism, plant and animal waste, decomposing. The organomineral A and organomineral B fertilizers stand out positively among the others, in relation to the organic matter and organic carbon contents. Height and stem diameter shows better results in the conventional system, than the Biodegradable system. The conventional tube provides greater accumulation of macronutrients in the acacia, mahogany and eucalyptus seedlings when compared to the biodegradable ones. The biodegradable tube provides greater accumulation of iron in some treatments in the acacia, mahogany and eucalyptus seedlings, and for the other micronutrients the greater accumulation was in the conventional tube.

Demand for quality seedlings of forest species is becoming increasingly widespread, due to increased planted area and the restoration of degraded environments. Based on the importance of substrate for seedling production and use of renewable materials in its formulation, the aim of this work was to characterize the physical properties of renewable substrates composed by coconut fiber and composted sludge and evaluate the feasibility of using these substrates in the production of seedlings of Eucalyptus grandis and Acacia mangium. Therefore, there were three studies. The sources of organic materials used for the composition of the substrates were commercial substrate, coconut fiber and composted sludge (waste from the tomato processing industry). The treatments were: commercial substrate; commercial substrate + 10% sludge; commercial substrate + 20% sludge; commercial substrate + 40% sludge; coconut fiber; Coconut fiber + 10% sludge; coconut fiber + 20% sludge and coconut fiber + 40% sludge. In the first study were performed following physical analysis of formulated substrates: volume density, particle density, porosity, air space, readily available water, buffering water, available water, the remaining water of 100 cm and water retention capacity. It was observed that treatments showed a great variability in the physical characteristics and no advantage in doing mixtures to obtain a more efficient substrate on these properties. As a conditioner of the mixes, the composted sludge promoted increased density, reduced porosity and increased water retention capacity. In the second study, parameters relating to the growth of Eucalyptus grandis seedlings were evaluated, and the third study evaluated parameters relating to the growth of Acacia mangium seedlings. The evaluated parameters were: plant height, stem diameter, dry matter of aerial part and radicial part, ease of removal of the cartridge seedlings, roots aggregation of the substrate and chemical analysis of the aerial part of the plant. The results showed that the use of sludge and composted coconut fiber as substrate for the production of Eucalyptus grandis and Acacia mangium seedlings is a promising alternative because it resulted in the adequate development of the same. The use of organic waste in the substrate composition for the production of forest trees seedlings is a technically feasible option and is an alternative to recycling and use of by-products of agribusiness.

(Universidade Federal de Goiás, 2015-05-21) Muniz, Edgard Alves; Leandro, Wilson Mozena; Brasil, Eliana Paula Fernandes; http://lattes.cnpq.br/7324619074753727; Leandro, Wilson Mozena; Borges, Jácomo Divino; Resende, Cláudia Fabiana Alves; Ferreira, Luciana Domingues Bittencourt; Cunha, Patrícia Pinheiro da
The latosolic Concretionary Petric Plintosol is the less fertile soil in the bioma Cerrado. Making it to produce food in order to contribute to the Brazilian agribusiness, turns into a great challenge for Science. In addition to this fact, the\pineapple fruits exports are important incomes sources for our Country. For this reason, the present work aimed to assess effects of application, on soil, of calcium carbonate, calcium & magnesium carbonate and calcium sulfate, on productivity of pineapple plant (Ananas comosus L. Merril) var. Pérola cultivated in typical Distrocohesive Yellow Latosol and latosolic Concretionary Petric Plintosol on a same topossequence of Cerrado bioma. Soon after planting, it were applied on both soils, the following equivalent doses\(kg ha-1): on the latossol area – 2000, 2000 and 1000; and on the plintossol area – 3000, 3000 and 1500; of calcium carbonate, calcium & magnesium carbonate and calcium sulfate, respectively. As effects, the fruits production averages (t ha-1), in both soils were: 8,32; 12,94; 13,82; 15,09; 5,02; 12,60; 14,11; e 14,82, respectively, in the same sequence above. The essays were set up in 2010, in a region of Anápolis, Goiás State, latitude 16º19ˈ 36 ̎ S, longitude 48º57ˈ 10 ̎ W and altitude 1017 m. The yearly pluviosity average is 1.200 mm, and the temperature oscillates between 21 and 35ºC; the climate is classified as Aw according to Köppen system. The harvest was achieved in 2012. The experimental design was in randomized blocks. Each plot measured 1,20 x 6,60 m and were four the number of treatments with five replications. The three products, in the mentioned equivalent doses, induced the latosolic Concretionary Petric Plintosol studied to reach a pineapple Pérola production capacity equivalent to the typical Distrocohesive Yellow Latosol. Calcium sulfate, calcium carbonate and calcium & magnesium carbonate, individually, increased the tenor of changeable bases in the upper layers of both soils, wich made it possible to obtain greater pineapple Pérola yielding.

Rice cultivation upland stands out in the Cerrado region and on the climatic conditions of the region, management studies of nitrogen fertilization become essential for greater efficiency in the use of this nutrient. The aim of this study was to evaluate the response of cultivating upland rice BRS-Emerald to different nitrogen sources and doses in the Brazilian Cerrado. The experiments were conducted in Goiânia, GO in the agricultural years of 2013/2014 and 2014/15 in Oxisol. The experimental design was a randomized complete block in a factorial 3x4 + 1 (3 fonts, 4 doses and control without N) with four replications. The nitrogen sources used were conventional urea (Uconv); urea treated with NBPT® urease inhibitor (NBPT) and coated urea Kimcoat® polymers (N+) tested in doses 30, 60, 90 and 120 kg ha-1 of nitrogen in rice upland BRS Esmeralda spacing 0.5 m between rows. For the characteristics evaluated nitrogen source NBPT was superior to other sources in the development of rice cultivar BRS Esmeralda. For the characteristics evaluated the soil quality bioindicators little or nothing were influenced by nitrogen source, the biomarkers were more influenced by the planting period and doses of nitrogen applied.

(Universidade Federal de Goiás, 2014-02-19) Rezende, Cláudia Fabiana Alves; Leandro, Wilson Mozena; Brasil, Eliana Paula Fernandes; http://lattes.cnpq.br/7324619074753727; Brasil, Eliana Paula Fernandes; Souza, Eli Regina Barboza de; Leandro, Wilson Mozena; Nascimento, Abadia dos Reis; Gonçalves, Helenice Moura
One of the most competitive and growth potential of the agribusiness sector is the citrus industry. Citrus nurseries grown in protected cultivation, constitutes one of the foundations of this growth. To achieve high productivity in any culture, there are a number of factors, among which the supply of nutrients, in the manner and in adequate quantity becomes paramount. The Diagnosis and Recommendation Integrated System (DRIS) was developed to provide a diagnosis of the nutritional status of cultivated plants, helping the decision on fertilizer recommendation for crops, being based on the balance of essential nutrients to plants. The objective of this study aimed to obtain a database of foliar analysis for establishment of DRIS and assess the nutritional status of two rootstocks (Rangpur lime and Swingle Citrumelo) and two combinations of citrus seedlings (Orange Pear/Rangpur lime and Orange Christmas /Swingle Citrumelo) grown in ‘Goiás’ collections hundred twenty leaf samples for rootstocks and one hundred and twenty leaf samples for ready seedlings were performed . With the data obtained organized a database. The database was analyzed by the tracks or Critical Levels of Concentration and DRIS method by method. Bands Concentration diagnosed for the Rangpur Lime rootstock , the most limiting nutrient deficiency were Mg and Zn and excess P and Fe. For Citrumelo Swingle, limiting disability K, S, Mn, Cu and Zn, excess Fe and N. For the citrus nurseries K, S and Zn were the nutrients most limiting nutrient deficiency and P, Fe, Mg and N in excess. Zn is the nutrient most often deficiency and Fe excess among rootstocks and citrus nurseries. The DRIS diagnosed S as the most limiting disability and N as the most limiting for excess, and still showed higher sensitivity for diagnosing nutritional problems.

(Universidade Federal de Goiás, 2020-03-27) Santos, Tamara Rocha dos; Leandro, Wilson Mozena; http://lattes.cnpq.br/9052207260053937; Brasil, Eliana Paula Fernandes; http://lattes.cnpq.br/7324619074753727; Leandro, Wilson Mozena; Nascimento, Abadia dos Reis; Ferreira, Gislene Auxiliadora; Silva, Vanderli Luciano da; Calil, Francine Neves
The objective of this work was to select energy cane genotypes in different agricultural production systems (organic and conventional) and to evaluate the influences of fertilization on some phenotypic and agronomic characteristics in first and second year harvest. The two field studies were carried out in an experimental area belonging to the Federal University of Goiás, in Goiânia-GO, one of the experiments being carried out in an area certified as organic by IBD (certificate GO-022-001) and the other in a conventional area. A greenhouse test was also set up. The soils in the experimental areas (organic and conventional) are classified as Latossolo Vermelho Distroférrico and the one used in the greenhouse is the Latossolo Vermelho Ácrico. In the field experiments, the test was carried out in plots consisting of 7.5 m2 per plot with borders of 1.5 m (5 meters in length, spaced in 1.5 m) with the planting of sheets containing three buds in 30 cm furrows. depth, with three sheets per meter. The experimental design was a randomized block with five replications. And in a field experiment, the treatments were: T1- Organic fertilization (200 m3 / ha of biofertilizer) and T2- Control (without fertilization) and the second factor, the genotypes: UFPR 1274, UFPR 1230, UFPR 12180 and UFPR 127004. In the greenhouse, the experimental design was randomized blocks, in a factorial scheme, 2x5, the first factor being: T1- Nitrogen fertilization (50 mg / kg of urea) T2- Control (without fertilization) and the second factor, the genotypes: RB 127008, UFPR 1230, UFPR 1213, UFPR 1274 and a commercial cultivar with four replications. 24 energy cane genotypes were used, obtained from the Energy Cane Genetic Improvement Program at the Federal University of Viçosa (PMGCA / UFV / RIDESA). The agronomic and phenotypic variables carried out in the field studies were: content of soluble solids (Brix°), plant color, plant height, stem diameter and total biomass. The variables evaluated in the greenhouse study were: plant height, stem diameter; root growth, root volume and leaf area. It is concluded that the energy cane genotypes evaluated show high productivity, showing great potential for planting in conventional system. The genotypes with the highest performance in terms of biomass are: RB 127004, UFPR 12157, UFPR 1265, UFPR 12180 and UFPR 1277 in the conventional system and RB 127004 and RB 127035, UFPR 1273, UFPR 12180 and RB 127024 in the organic system. The phenotypic variable that correlates with biomass in the two production systems is the stem diameter. The energy cane genotypes evaluated are not responsible for chemical nitrogen fertilization or organic fertilization. The genotypes UFPR 1274 and the commercial variety show higher performances in terms of leaf area under nitrogen fertilization and the genotypes with higher performances in terms of biomass are: RB 127008 and UFPR 127004 under organic fertilization.
Frações da matéria orgãnica e atributos biológicos do solo em veredas conservadas e antropizadas no bioma cerrado
(Universidade Federal de Goiás, 2013-08-14) Sousa, Ricardo Fernandes de; Leandro, Wilson Mozena; Brasil, Eliana Paula Fernandes; http://lattes.cnpq.br/7324619074753727; Madari, Beáta Emoke; Leandro, Wilson Mozena; Borges, Jácomo Divino; Figueiredo, Cícero Célio de; Brasil, Eliana Paula Fernandes
Veredas (a type of wetland) are humid ecosystems, generally associated to hydromorphic soils and shallow water table, which occur frequently in the neighborhood of the springs and watercourses in the Cerrado region. The objective of this work was to study the soil of wetlands located in conserved and altered environments (agricultural areas and pastures), by determining the organic matter fractions, and biological attributes of the soil. The study was carried out in the central region of Cerrado biome, in the state of Goiás (Brazil), in wetlands situated in the City of Bela Vista de Goiás. Three wetlands were selected for soil sampling, as follows: a preserved wetland, surrounded by natural vegetation (cerrado); an area disturbed, with the occurrence of pasture around it; and another wetland also disturbed, with the occurrence of annual crops (agriculture) in its surroundings. The samplings were taken during the dry season, in months of July and August of 2012, along reference lines arranged according to their position in the slope, in the upper, middle and lower position, in approximate direction of the drain line of the wetland. Samples were collected at two depths: 0-10 cm and 10-20 cm. The variables studied were: Total soil organic carbon and nitrogen, and soil C:N ratio; C and N contents, and C:N ratios of the particulate and mineral-associated organic matter; fulvic acid, humic acid and humin, and humic acids to fulvic acids ratio, C contents of humic substances and its ratio to total soil organic carbon; carbon and nitrogen contents, and C:N ratio of the microbial biomass; microbial quotient; microbial biomass N to soil total nitrogen ratio; basal soil respiration; metabolic quotient; and fluorescein diacetate (FDA) hydrolytic activities in soil. In the lower position of slope the total soil organic C and N contents (in both depths), and levels of organic carbon in particulate organic matter, humic substances and soil microbial biomass (to 10 cm depth only), are smaller in the agriculture surrounding environment. Also in the lower position of slope in the topsoil, the soil total N, and N levels in particulate organic matter and microbial biomass are significantly larger in the wetland neighboring pastures. In the topsoil, the organic C contents of the mineral-associated soil organic matter fraction are larger in the conserved ecosystem, in all slope positions. In general, the farming in the vicinity of the wetlands promoted changes in soil microbial and biochemical attributes, as well as those related to soil organic matter in these ecosystems, with changes in C and N biogeochemistry processes. These changes are especially pronounced in the lower position of the slopes, with clear differences also between this lower zone and the highest slope positions (upper and middle) of the wetlands.
