“…Soybean crop fertilization can be carried out in the sowing furrow, or in the soil surface, taking into account the soil type, mobility and dynamics of each nutrient [2,3]. Fertilization management may influence directly in reactions among fertilizer, soil and nutrient availability to plants [4]. Among the fertilization philosophies, one of them can be determined as system fertilization, characterized by the partial or total fertilizer anticipation of summer crop at predecessor crop sowing [5].…”

System fertilization is characterized by partial or total fertilizer application at the predecessor crop; and it can be a viable practice to soybean crop. This study aimed to determine the fertilizer management and fertilizer levels for black oat-soybean cropping system, in high fertility soils and no-tillage system. The field trial was conducted in a bifactorial scheme, consisting of six environments, by combination of locations (Bom Sucesso do Sul -Paraná, Itapejara d'Oeste -Paraná) and fertilization management (all fertilization in black oat; splitting with 50% in black oat and 50% in soybean, all fertilization in soybean), and four fertilizer levels (0, 100, 200 and 300%) defined according to soil analysis and production expected. The evaluated traits were dry mass production, N, P and K nutrient accumulation of straw, dry mass remaining of black oat crop; and plant height, number of pods per plant, thousand grain weight, grain yield for soybean crop. Higher black oat dry mass production was observed at higher fertilization level. The fertilizer anticipation in black oat crop had better performance. Phosphorus and potassium accumulation increased linearly with fertilizer level increase. For N, the highest accumulated value occurred at the 200%, decreasing at the 300% of fertilizer level. The soybean crop had no influence in grain yield considering fertilization management, anticipation or splitting, and fertilizer levels. Thus, the system fertilization can be a viable practice, and favor black oat dry mass production and soybean development. HIGHLIGHTS All early soybean fertilization for black oat increase dry mass.  Higher black oat dry mass provides higher amount of nutrients to summer crops. Soybean grain yield is kept in system fertilization. 2 Zanella, Rodrigo; et al.

“…The increase in food production is directly related to innovation in the use of fertilizers in agricultural systems, so without the use of this resource, current production levels would not reach this level. Correct fertilization management directly influences the reactions between soil and fertilizer by effectively making nutrients available to plants (FIORIN et al, 2016). Several types of fertilizers with different chemical compositions, nutrients, efficiency and granulometry are offered on the market (HANSEL et al, 2014).…”

Water is the main input used in shrimp farming, and the good quality of this natural resource is not only essential for the farmed animals' welfare, but also for a good profitability at the end of the farming process inaquaculture species. Pyroligneous extract (PE) is a yellow to reddish-brown liquid obtained from the condensation of gases produced by partial wood combustion. This compound has been used for several purposes in different areas, such as in the fertilization of various vegetable crops and in soil conditioning. The objective of the present study was to evaluate the possible benefits of the application of pyroligneous extract on water quality and its consequences on the production performance of Penaeus vannamei. Six 1.0 ha ponds were used, 3 of which were used for the application of pyroligneous extract (WPE) and the other 3 without the extract (wPE) for comparison purposes. The extract was diluted in water and applied directly to the dry soil and after a few hours of reaction the ponds were filled with water and prepared for cultivation. There was a significant difference (p<0.05) between the ponds (WPE) and (wPE) in the following water quality parameters: dissolved oxygen, pH, total alkalinity, total hardness, magnesium and silica. However, the values found

RESUMO Atualmente, o Brasil se destaca mundialmente como o segundo maior exportador e produtor de grãos de soja. Recentemente a soja vem se destacando como uma cultura que tem a maior área cultivada e determinante para a expansão da fronteira agrícola. Neste sentido, o presente trabalho teve como objetivo avaliar o desenvolvimento inicial da cultura da soja em função de diferentes doses de fertilizante N-P-K (nitrogênio, fósforo e potássio), com o intuito de determinar a melhor dose, de maneira que permita um melhor aproveitamento dos nutrientes pela planta na fase de desenvolvimento inicial. O delineamento experimental utilizado foi o de blocos casualizados, com quatro tratamentos e oito repetições. Os tratamentos consistiram em quatro doses de N-P-K aplicados na semeadura da soja, com valores de 0, 25, 50 e 100% da dose recomendada para a cultura. As variáveis avaliadas foram comprimento da raiz, altura da planta, número de folhas, massa da parte aérea, da raiz e massa total, sendo coletadas cinco plantas para análise. Os dados foram tabulados e submetidos à análise de variância e à análise de regressão para seleção do maior expoente significativo, foi utilizado o programa estatístico SISVAR 5.3. Dentre as variáveis avaliadas, a variável número de folhas apresentou resultado significativo a 5%. Para a análise de regressão, obtiveram resposta significativa a massa da parte aérea e total da planta e o número de folhas, com melhores resultados para a aplicação entre 50 e 60% da dose recomendada.
