Intense soil preparation and disturbance in crops, over time, reduces the quantity quality of organic matter. Given this context, work aimed to determine carbon stocks labile fractions under agroforestry system (AFS) toposequences an altitude marsh, Taquaritinga do Norte, Pernambuco, Brazil. The study was carried out at Yaguara farm, areas studied were native forest with 4.57 ha coffee plantation shade 25.59 ha. Soil samples collected four trenches measuring 1.5 x 0.60 m, a distance 50...
Sorghum is a plant of tropical origin, short days and with high photosynthetic rates, requiring warm climate in order to express its production potential. The objective evaluate the agroclimatic aptitude cultivation sorghum that allows visualize or identify productive potential state Pernambuco. pluviometric data were acquired from Northeast Development Superintendence Pernambuco water agency, temperature National Institute Meteorology estimated by estima_T software between period 1960-2019....
MOS (soil organic matter) is a natural carbon reservoir, and divided into different stages of decomposition according to its solubility structural complexity. In view this context, work aimed quantify the content in humic fractions soil matter under an agroforestry system three toposequences swamp altitude Pernambuco, Brazil. The study was carried out on Yaguara farm, studied areas were native forest system. Soil samples collected trenches 1.5 x m, at depths 0-20, 20-40 40-60 cm, with four...
Heat stroke is part of solar energy that spreads without the need for a material medium and represented by hours day disk remains visible on earth's surface. The objective to characterize climatic conditions insolation using interpolation method area hydrographic basin Ipojuca River its surroundings, elaborating monthly annual graph period from 1962 2019. average climatological data total sunshine were generated simple method, electronic spreadsheets extract averages values of monthly,...
Precipitation is of extreme importance for the management water resources, since it a question degraded areas and with deforestation withdrawal firewood. Frequency analysis was performed on annual rainfall totals by drawing up graphs. The scale proposed Meis et al. (1981), meteorological CPTEC/INPE nuclei, provided Xavier (2005), values that approached mean value were characterized as intermediaries, in precipitation values, those that moved away 25% from average considered very rainy...
The knowledge of the climatic characteristics hydrographic basins, especially regarding temporal and spatial distribution rainfall, relative humidity air maximum, minimum average temperatures air, which offer important subsidies to management water resources agriculture. irregular rainfall indicates instability in entry into hydrological system, exercising control over availability time space, influences animal plant behaviors amount available atmosphere. temperature, on other hand,...
Through sustainable agriculture it is possible to explore the coffee culture in consortium with native forests more rugged reliefs, as a permanent crop addition climatic conditions offered by swamps that favor its development. Given above, present work proposes, based on acidity results, quantify need for correctives soil obtain better nutritional use agroforestry cultivation of organic shade favorable results increase productivity and, consequently, farmer's profit. The research was carried...
