“…This can be explained by greater biological activity in TM, which yielded the lowest C/N values and provided the highest dry matter of Brachiaria due to high P availability to plants (Tables 1 and 3). According to Boitt (2014), the addition of organic residues with low C/N in soil provides an increase in microbial biomass that drives low P adsorption in soil, as demonstrated by a negative correlation between OM and P in the study of Moura et al (2015). Probably, manures can alter biological activity in soil influencing the nutrients' dynamics.…”

Purpose Due to the pressures of conforming to environmental quality standards and the increased costs of mineral fertilizer importation, there is growing interest in the use of organic residues as fertilizers. To test the hypothesis that indicates the quantity of animal manure (AM) depends on the phosphorus (P) needs of the crops, an experiment was run using three organic animal manures (chicken-CM, turkey-TM, and cow manure-CoM), enriched with limestone, gypsum, and phosphorus. Methods A greenhouse experiment was run using AM incorporated in a clayey soil, at a rate that equates to the P needs of Brachiaria sp. Contents of phosphorus, potassium (K + ), calcium (Ca +2 ), magnesium (Mg +2 ), sodium (Na + ), organic matter (OM), and values of pH and cation exchange capacity (CEC) were monitored during 120 days. Plants were collected to determine the dry matter.

A bacia hidrográfica pode ser considerada como sistema físico de captação natural da água oriunda da precipitação onde o escoamento parte para o único ponto de saída. O objetivo do trabalho foi realizar a caracterização morfométrica da bacia hidrografica do Rio Caiapó, a fim de compreender sua relação com o uso antrópico da água. A análise morfométrica da bacia hidrográfica foi realizada no Estado de Goiás, que fica localizada na região do sudoeste goiano. A média anual da precipitação é de 1.500 mm e a média anual de temperatura de 23,3 ºC. A bacia hidrográfica do Rio Caiapó foi caracterizada com 12053,48 km², o perímetro total elevado é de 939,78 km, com coeficiente de compacidade de 2,39. Quanto ao fator de forma, o resultado encontrado foi de 0,14, o índice de circularidade de 0,17 e o índice de sinuosidade de 1,91. A declividade média encontrada foi de 9,02%, portanto, o relevo da área é considerado ondulado e a amplitude altimétrica de 773,65 m. É imprescindível uma fiscalização ativa e uma gestão socioambiental por parte do poder público por meio de políticas públicas mais eficazes.

“…These results are plausible because this nutrient has a fundamental role in the transfer of cell energy, respiration, and photosynthesis, besides acting as a structural component in plants [10]. Thus, the absence of the nutrient may also limit crop production factors, mainly in soils, where the natural availability of this element is found at low levels [21,22].…”

This study aimed to evaluate the response curve of phosphorus fertilization to the development and productivity of Salvia hispânica L. in Cerrado soils in the South of Tocantins. The Chia seeds used in the experiments came from producers in the region of Katueté -Paraguay. The experiments were carried out in the experimental area at the Federal University of Tocantins, University Campus of Gurupi-TO, in the agricultural years 2014/2016, through a randomized block design with four repetitions. The treatments consisted of five levels of phosphorus fertilizer (0, 30, 60, 90 e 120 kg ha −1 ). At 120 days after emergence, the following characteristics were evaluated plant height, upper stem height, stem diameter, bunches number, length of bunches, and grain Productivity. The data were submitted to analysis of variance and regression at the 5% probability level by the F test. The analysis of the results showed that the doses of 30 and 60 kg ha −1 of phosphorus influenced positively in the most development and productivity in the culture of Chia in the harvest 2014/2015. The results also showed that increasing doses of phosphorus had not positive effects in the agronomic characteristics at the cultu re of Chia n the harvest 2015/2016. The maximum grains Productivity found in the isolated doses of P was superior to 157 kg ha −1 .
