“…Insecticides and simple superphosphate sum had 49.01% of direct energy input, representing focus point for decision-makers dealing with citrus production energy approach. Few studies have been made to update energy embodiment indexes of agricultural inputs, such as MANTOAM et al (2014), who determined energy embodied for sugarcane harvester. Most of available data are from the 1970s and 1980s when the search for alternative energy sources due to oil shocks stimulated researchers to develop these indices.…”

“…1 Mantoam et al, (2014); 2 BEN (2013); 3 Pimentel (1980); 4 Campos et al, (2009). Para calcular o valor da hora trabalhada pelas máquinas é preciso definir o preço e a quantidade consumida dos itens de cada equipamento, em cada hectare, os gastos com o óleo diesel, salário e encargos sociais e trabalhistas dos seus operadores, de acordo com a equação a seguir (PACHECO, 2000):…”

“…Uma vez que máquinas agrícolas, não apresentam diferenças discrepantes entre os seus grupos de materiais (aço carbono; alumínio; borracha; ferro fundido e aço forjado), identificados como maiores consumidores de energia incorporada podem servir como base e ponto de partida para futuros estudos de energia incorporada com outras máquinas agrícolas (MANTOAM, et al, 2014). Alguns autores quando deparados com diferentes coeficientes energéticos relacionados ao mesmo item, adotaram como valor a média aritmética dos valores dos diferentes autores, gerando um novo valor que poderá ser utilizado para compor uma nova média por outros autores, originando um novo valor "empírico".…”
