Exercício:A aplicação de 100 mm de água na irrigação contendo 1000 g/m³ (de água) de sais, pode acumular 10 ton por hectare de sais no solo? Resposta: 1000 g = 1.000.000mg 1m³ = 1.000 litros 1000.000 mg ------------1.000 litros x------------------------------1litro x= 1000 mg/l = Pela tabela 1000mg/litro a injúria é baixa. Mas 100 mm pode acumular qto de sais no solo? 1mm = 10 m³/ha, ou seja, 0,001m x 1 x 1m = 0,001m3/m² 0,001m³ ---------------------1m² x-------------------------------10.000m² x = 10m³ de água/ha, entao 100mm = 1.000m³/ha 1000 g -------------1m³ x----------------------1000m³ x= 1.000.000g= 1000kg/ha= 1ton/ha Resposta= Acumulará 1 tonelada/ha
