ABSTRACT. Various approaches were developed considering the need to increase agricultural productivity in cultivated areas without more deforestation, such as the Integrated Crop livestock systems (ICLS). The ICLS could be composed of annual crops followed by pastureland with the presence of cattle. Due to the high temporal dynamic of rotation between crops over the season, monitoring these areas is a big challenge. Also, agricultural organizations worldwide highlight the need for early-season maps for this kind of work. In this context, this study evaluated the potential of open data (Sentinel-2) data to map ICLS areas. The performance of two classifiers was evaluated: one of Machine Learning (random forest) and the other of Deep Learning (LSTM). Three different time windows of data were tested (Entire season, 180 days, and 120 days). Using the RF classifier, it was possible to achieve satisfactory results (Overall accuracy higher than 80%) for the early season (180 days). However, further studies are needed to explain better the lower(when compared to Random Forest) accuracy achieved by LSTM net (0.79 % for 180 days) and compare the results achieved here with results for a study area with different rates of cloud cover. |

The nitrogen is the most required nutrient by the coffee culture and its application is usually done in the form of urea. Although easy to handle, significant losses of N to atmosphere may occurs due to the transformation of urea in ammonium, as a consequence of urease action, an enzyme produced by soil microorganisms. This work aimed to evaluate NBPT efficiency, an urease inhibitor, in the reduction of N losses by volatilization. The work was carried out in a greenhouse using a factorial design comprised of three N doses in the form of urea, in the presence and absence of NBPT, applied in two times, and with two ways of irrigation: before and after fertilizer application. Three independent treatments were added: a control without N, and 7.2g of N in just one application with and without NBPT. Dry weight and mobilized N were evaluated four months after the treatments. It was found that the addition of NBPT to urea significantly increased dry weight and mobilized N per plant, and that the response was proportional to the N applied. No response was observed to the time of irrigation. In the treatments where N was applied in just one dose, plant death was observed in two days in absence of NBPT, or in six days, when NBPT was used, corroborating the idea that NBPT can delay N volatilization. |
