Biochar is considered a tool in the process of transforming waste into potential soil conditioners. Low molecular weight organic acids (AOBPM) interacting with biochar have the ability to solubilize nutrients present in carbonized materials, impacting soil enrichment and consequently reducing the use of chemical fertilizers by updating organic waste. The present work aims to evaluate the total and available P and K contents in coffee straw (PC) and eucalyptus bark (EC) biochars produced under two pyrolysis temperatures, 350 and 600 °C, as well as the solubilization of the inorganic content of these biochars from the addition of AOBPM. The was conducted in the laboratory under a completely randomized experimental design, with three replications per treatment, and three P.A organic acids (acetic, oxalic and citric), in six different concentrations (0; 0.5; 1.0; 1.5; 2 .0 and 2.5 mmol/L). The available P and K contents were determined by extract via colorimetry in a UV-visible spectrophotometer and flame photometry, respectively, total P and K contents through nitroperchloric digestion, and X-ray diffraction analysis of the biochars. There was a difference in solubilization of the inorganic content based on the pyrolysis temperature for the two materials, with PC biochar having higher levels of available P in relation to total P at the pyrolysis temperature of 350 °C, and higher levels of available K in relation to the total K at the pyrolysis temperature of 600 °C. For EC biochar, higher levels were found at a pyrolysis temperature of 600 °C. The presence of organic acids interacting with biochars can cause an increase in the availability of nutrients, such as P and K, with an increase in solubilization in all acids and all doses above 0.5 mmol/L. In our observations, no differential solubilization effect was observed depending on the type of organic acid. The pyrolysis temperature and biochar raw material interferes with the availability of nutrients present in the materials, with the inorganic content being better solubilized at a pyrolysis temperature of 350 °C for PC, and 600 °C for CE. Mechanisms for solubilizing inorganic content in biochars must be stimulated in order to better take advantage of the nutrient source role of phosphorus and potassium in biochars, even if these materials are not applied to the soil with the main objective of functioning as a vehicle for fertilization.

ADUBAÇÃO MINERAL E BIOESTIMULANTES EM PASTAGENS DEGRADADAS NO BIOMA MATA ATLÂNTICA
(Universidade Federal do Espírito Santo, 2022-05-24) Castro, Andre Soares de; Mendonca, Eduardo de Sá; https://orcid.org/0000000332847129; http://lattes.cnpq.br/4735276653354808; https://orcid.org/; http://lattes.cnpq.br/; Souza, Gustavo Soares de; https://orcid.org/0000-0002-8207-0218; http://lattes.cnpq.br/6563795137628376; Burak, Diego Lang; https://orcid.org/0000000267583517; http://lattes.cnpq.br/2501042964619476
Soil degradation is an aggravating factor throughout the country, which is subject to the event for several reasons, such as poor soil management, poor phytotechnical management of plants, including livestock management, in addition to the relief, which many of the are accentuated and also climatic factors. Thus, soil degradation has been highlighted in the livestock sector as one of the main aggravating factors of low productivity, which suffers daily from a reduction in forage yield, which directly advocates the yield of Brazilian herds and the production costs of this activity. Given the above, the present work aimed to recover the productive capacity of pastures in areas with conditions of high level of degradation subjected to the use of biostimulants in two tropical forage species and on two perspectives of soil management systems (with scarification - SCE and without scarification – SSE). Thus, the use of scarification (SCE), associated with biological inputs, and the reduction of mineral fertilization provided better technical characteristics and green and dry biomass for forage plants Urochloa cv. Marandu and Stylosanthes cv. Campo Grande I and II. It is also noteworthy that the use of scarification (SCE) provided better results in the distribution and amount of root biomass and physiological characteristics, in addition to presenting lower soil compaction results in relation to the system without scarification (SSE). It is noteworthy that, in both forages, the use of biotechnologies associated with SCE, and with reduced doses of mineral fertilizer, showed values similar to the use of 100% mineral fertilizer (treatment 2). Thus, the use of biostimulants for regions with sloping relief, low rainfall, little technology and low availability of nutrients, can be an alternative in the initial recovery of areas with a high level of degradation.

The yacon (Smallanthus sonchifolius) is a plant of the Asteraceae family and comes from the Andean region, which has many nutraceutical and medicinal properties. The interest in the plant aroused due to the high content of fructooligosaccharides (FOS) presented in its roots, making yacon a functional food. Like other crops, the study of the ideal conditions for their cultivation is essential and, thus, the importance of obtaining information about the mineral nutrition of yacon is observed. As potassium is a mineral nutrient considered essential for the growth and development of all plants and one of the most accumulated nutrients in this species, the objective of the present study was to evaluate different doses of potassium fertilization in the phytotechnical and physicochemical characteristics of yacon. The experimental design used was randomized blocks (DBC), with 4 replicates per treatment, which consist of 4 different doses of potassium fertilization: 178.7 kg.ha-1; 357.4 kg.ha-1; 536.1 kg.ha-1; 714.8 kg.ha-1 of potassium chloride (KCl); and the witness: soil without fertilization. Potassium fertilization improved the chemical characteristics (higher levels of soluble solids and less acidity) and physical characteristics (less hardness, chewability, cohesiveness and adhesiveness) of yacon's tuberous roots, bringing higher quality to the final product. Since the dose of 357.4 kg.ha-1 of KCl was the one that presented the highest agronomic efficiency for the cultivation of yacon, being able to provide the greatest economic efficiency by producing larger quantities of roots in the most valued classes in the market.

Swine wastewater (ARS) is generated in large quantities on swine farms, and this residue has a high organic load that, if well managed, provides water and nutrients for crops and, by associating its use with conservationist forms of soil management, as the no-tillage system, can be a sustainable alternative for the recovery of degraded areas and maintenance of water and nutrients in the soil. In this sense, this work sought to highlight two premises: i) the establishment of a conservationist management system together with the increase of different depths of swine wastewater provide changes in the chemical and physical properties of the soil and; ii) the use of irrigation with ARS in conjunction with the no-tillage system provides an increase in the development and mineral nutrition of corn. In view of the proposed, the objective of this work was to evaluate the potential of the agricultural use of ARS in the irrigation of corn, cultivated in different irrigation depths and soil management systems, through the morphoagronomic parameters of corn, as well as on the attributes chemical and physical properties of the soil and on the foliar contents of macro and micronutrients in field work. The experiment consisted of two soil management systems, conventional tillage system (SPC) and no-tillage system (SPD), and five irrigation depths with ARS (50%, 75%, 100%, 125%, and 150% of the real evapotranspiration-ETc of the maize crop), with three replications and implanted in a 5x2 factorial scheme cultivated in strips. The present study, conducted in the experimental area of Ifes - Campus de Alegre, is part of a project started in 2017 where two cycles of corn cultivation have already been conducted. The data presented represent the results of the third cropping cycle in the same experimental area. During the maize development cycle, leaves were collected at the tacking stage to determine the leaf contents of N, P, K, Ca, Mg, Cu and Zn. The evaluation of the morphoagronomic parameters of corn was performed when the plants were at an appropriate stage for silage. At the end of the corn cycle, soil samples were collected in the 0-10, 10-20 and 20-40 cm layers for further chemical and physical analysis of the objects under study. In general, the ARS depths provided the highest significant means for the chemical attributes tested if observed under conventional soil management. Most chemical attributes showed some difference between the averages obtained in the comparison between SPC and SPD in the ARS slides tested. However, at 0 to 10 cm depth this did not occur for potassium, sodium, H+Al and TOC; at a depth of 10 to 20 cm there was no difference in the values of pH, Na, H+Al, Zn and TOC; and at a depth of 20 to 40 cm there was no difference for pH, Na, Al, H+Al, Cu, Fe and COT which were not influenced by any of the management systems adopted. In general, there was no difference between the averages obtained for the physical attributes analyzed in the comparison between the management systems and in the ARS blades applied at the different investigated depths. Soil management systems did not influence the foliar contents of the evaluated nutrients, with the exception of Ca, which showed the highest levels in all ARS depths in the SPC. Ear weight in green mass (PEMV) and plant dry mass (MSP) responded linearly to the increase in ARS blades, proving the positive effect of ARS in increasing the production of plant material for silage production, in addition to favoring the increase in AP, AIE, DC and MFP.

The objective of this work was to raise and discuss information about arboreal communities of two forest fragments, considering the lack of studies of vegetation of the south of the Espírito Santo state. The fragments are located in the municipal of Cachoeiro de Itapemirim, being the Floresta Nacional (FLONA) de Pacotuba and the Reserva Particular do Patrimônio Natural (RPPN) Cafundó. In FLONA de Pacotuba, the composition floristic consisted of 258 species and in RPPN Cafundó of 258 species, being 111 species common to the two fragments. The richest families in species in FLONA of Pacotuba are: Fabaceae, Sapotaceae, Euphorbiaceae, Myrtaceae and Meliaceae; while in RPPN Cafundó are: Myrtaceae, Fabaceae, Sapotaceae and Euphorbiaceae. In the analysis of the similarity of FLONA de Pacotuba and of RPPN Cafundó, it was demonstrated that in spite of the geographical proximity, the different disturbance reports and regeneration, they resulted in different floristics compositions between these fragments. Being considered the diversity, the index of Shannon-Weaver (H) found in RPPN Cafundó (4,13), reach a more expressive value than the FLONA of Pacotuba (3,31). The value found for equability (J) is 0,60 in FLONA of Pacotuba and 0,74 in RPPN Cafundó. In the horizontal structure of FLONA of Pacotuba, the species Senefeldera verticillata, Actinostemon estrellensis and Anadenanthera peregrina dominate the community in relation to IVI(%); in RPPN Cafundó, the species that more stood out in IVI(%) are: Astronium concinnum, Pseudopiptadenia contorta and Neoraputia alba.The RPPN Cafundó presents larger number of individuals for hectare in the first diameter classes. The diametric structures of the fragments follow the general pattern of the uneven-aged forests, in reversed-J-shape. The vertical structure varies of 2 until 50 meters in FLONA de Pacotuba and of 2,1 until 54 meters in RPPN Cafundó
