Biochar-based fertilizers are a new attractive alternative to P supplementation for crops, as they can gradually release the nutrient, avoiding losses and improving soil quality. In this re-gard, the evaluation of the P ...

Biochar has gained agricultural importance as a soil amendment because of its important agricultural properties such as water retention, plant nutrient supplier, promoter of microorganism growth, sequestration action of ...

Laser-induced breakdown spectroscopy is an optical emission technique quite suitable for the analysis of recalcitrant materials as it eliminates complex procedures of sample preparation. However, for some simple LIBS ...

The use of fertilizers with slow releasing rates in agricultural practice has proven to be a viable and sustainable practice to increase the efficiency of nutrient elements assimilation by crop plants. In this context, the ...

The determination of N is an important demand for several sectors and the analytical features of laser-induced breakdown spectroscopy (LIBS) are very attractive to accomplish this task. In this work, a novel proposal for ...
