ABSTRACT- Pesticide applied incorrectly may result in wasted products, poor or no control, damage to crops or environmental contamination. The aim of this publication was to organize in one publication several technical information found in the scientific literature of herbicide application technology. This approach will help farm growers, students and technicians to know how to apply herbicides correctly and solve some practical problems related with. It was discussed definitions and concepts about application tecnology, environmental factors that influence the application quality, equipments characteristics, like nozzles tips selection and sprayers. All the content were discussed generally because the intention of the authors was to be brief and objective, recognizing that several important questions and items will need to be detailed by the reader with another bibliography. |

& Key message In loblolly pine land use of 17?32 years following forest clearing, CH4 consumption and N2O emission diminished by 17 years, due to high soilmoisture (~ 80%WFPS, N2O intoN2), but increased by 32 years, where medium moisture favoured methanotrophy and denitrification into N2O. Soil greenhouse gases (GHG) emission was positive by 17 years, but negative by 32, when soil sequestered carbon. & Context Much of the role of planted forests in the gaseous soil-atmosphere exchanges in the subtropics remains to be evaluated. & Aims To assess the impacts of loblolly pine (Pinus taeda L.) on soil nitrous oxide (N2O) and methane (CH4) fluxes in a subtropical Cambisol. & Methods Fluxes were monitored over 1 year with static chambers, in forest stands under natural forest (NF) and pine plantation for 17 (P17) and 32 years (P32). & Results The NF soil showed the lowestN2O emission and the highest CH4 consumption, because of the lowest water-filled pore space (WFPS, < 40%) and highest soil macroporosity. In P17, N2O emission was still low, but CH4 consumption diminished sixfold, possibly because of the predominance of methanotrophy, favoured by the highest WFPS (~ 80%) and lowest macroporosity that together with low mineral N concentration also did not favour the formation of N2O. In P32, the improved soil mineral N, macroporosity and intermediate WFPS (~ 60%) increased CH4 consumption and also N2O emission, in an environment supposedly favourable to methanotrophy and also to N2O production. Considering soil organic carbon (SOC) from a concurrent study, the net GHG emission (Mg Ceq ha?1 year?1) was 2.8 in P17 and ?1.1 in P32.
