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.

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.

The coffee tree can be grown in different environments due to its phenotypic plasticity, as well as the existence of pre-selected genotypes. The benefits provided by shading, associated with morphological, physiological and nutritional modulations can be an important strategy for the cultivation of coffee, especially in regions where water restriction is more pronounced, high levels of solar radiation, elevated atmospheric temperature and high demand nitrogen fertilization. The objective of this work was to evaluate and quantify the morphophysiological responses of Coffea canephora genotypes to shaded and full sun cultivation. The treatments were added to the completely randomized design, in a 14x2 factorial scheme, with 14 genotypes of Coffea canephora, 2 levels of irradiance, full sun and 30% shaded. Each treatment consisted of 4 experimental units. The level of 30% shading determined based on work is already done. The 14 genotypes used are elite genotypes from the active germplasm bank of Coffea canephora of the Capixaba Institute for Research, Technical Assistance and Rural Extension. The experiment was conducted at the Experimental Farm of Bananal do Norte, belonging to Incaper, located in the municipality of Cachoeiro de Itapemirim-ES. The effect of cultivation in full sun and shade was evaluated through variables in the pellet phase: chlorophyll, flavonoid, anthocyanin indices, nitrogen balance index, leaf nitrogen content and leaf nitrogen accumulation, and at harvest: branch diameter plagiotropic, length of the plagiotropic branch, number of leaves per plagiotropic branch, unit leaf area, total leaf area, leaf dry matter per branch, number of rosettes per plagiotropic branch and plagiotropic branch harvest index. Studying the chlorophyll index, genotypes 103, 2B / 88, 108, 820/87, 207, 302, 303 and 304 stood out in full sun and genotypes 2B / 88, 80S, 820/87, 207 when shaded. Regarding the flavonoid index, genotype 104 stood out in full sun, with lower flavonoid values and genotypes 103, 2B / 88, 105, 108, 80S, 109, 820/87, 207 and 302 lower values when shaded. As for the anthocyanin index, genotypes 105, 108, 820/87, 207, 302 and 304 were the ones that showed lower values for anthocyanins in full sun, and genotypes 2B / 88, 108, 604/97, 820/87, 207, 302 and 303 had the lowest values when shaded. Analyzing the nitrogen balance index, genotypes 104 and 207 stood out in full sunlight and genotypes 2B / 88 and 207 when shaded. For leaf nitrogen content there was no significant difference between genotypes in full sun, only the level of shaded comparison showed difference, with genotypes 103, 2B / 88, 106, 104, 108, 109, 820/87, 303 and 304 those that stood out with the highest levels of leaf nitrogen. For leaf nitrogen accumulation, genotypes 108, 80S and 303 were the ones that stood out in full sun and genotypes 103, 2B / 88, 109 and 304 when shaded. Genotypes 104, 108, 207 and 303 in full sun showed higher values for the diameter of the plagiotropic branch, when shading genotypes 103, 604/97 and 207. For the length of the plagiotropic branch in full sun, genotypes 104, 108, 820 / 87, 207 and 203 stood out, already in the shaded system the genotypes 103, 2B / 88, 105, 108, 80S, 109, 604/97, 207, 302 and 303. For the number of leaves per plagiotropic branch, genotypes 108 and 303 were the ones that stood out in full sun and shaded genotypes 2B / 88, 105, 604/97 and 304. For the unit leaf area, genotypes 108, 207 and 302 stood out in full sun and genotypes 108, 820 / 87 and 207 when shaded. Analyzing the total leaf area, genotype 108 stood out in full sun and genotypes 820/87, 207, 303 and 304 when shaded. For the leaf dry matter variable, genotypes 108, 80S and 303 stood out in full sunlight and genotypes 103 and 304 when shaded. For number of rosettes, genotypes 103, 106, 104, 108, 80S, 207 and 303 stood out in full sun and genotypes 80S and 820/87 when shaded. Analyzing the harvest index, genotype 604/97 stood out in full sunlight and genotypes 106, 105 and 604/97 when shaded. In view of the above, it is possible to identify that genotypes 105, 106 (12 and 6 Vitória Incaper 8142), 80S, 820/87, 604/97, 207, 303 (408 Marilândia) and 304 have answers that may be related to greater fitness for shaded cultivation. Genotypes 104, 108, 207 and 303 showed full sun responses, reinforcing their potential for this cultivation system.

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
