Foi determinada a composicao quimica proximal, bem como a energia metabolizavel corrigida pelo balanco de nitrogenio (EMn), a materia seca aparentemente metabolizavel (MSAM) e o coeficiente de triptofano aparentemente metabolizavel (CTAM) de 16 ingredientes atraves de um ensaio biologico. O delineamento experimental foi inteiramente casualizado, com tres repeticoes, e os tratamentos organizados em um esquema fatorial 17 x 2 (16 alimentos + uma racao referencia) e duas idades- 21 e 42 dias. Os alimentos analisados apresentaram variacoes na composicao quimica e nos valores energeticos em realcao aos citados nas tabelas estrangeiras. Nao foram observadas diferencas significativas (P>0,05) nos valores de EMn, MSAM e CTAM dos alimentos nas idades estudadas. Os valores medios de EMn (kcal/g), em base de materia seca, e de MSAM (%) foram, respectivamente, para feno de alfafa: 2,67 e 56,64; farelo de amendoim: 2,38 e 49,84; caupi 3,36 e 64; caupi torrado: 2,93 e 57,07; caupi cozido: 3,52 e 70,07; guandu: 2,43 e 51,56; guandu torrado: 2,49 e 46,66; guandu cozido: 2.83 e 61,41; farelo de soja: 3,14 e 61,20; farelo de carne e osso suinos 3,23 e 57,25: farinha de sangue: 3,08 e 64,37; farelo de arroz desengordurado: 2,59 e 52,89; milho cozido; 4,10 e 82,92; milho moido 1: 3,78 e 85,56; milho moido 2: 3,89 e 88,81; e farelo de trigo: 3,10 e 62,11. |

Agricultural use is the main way of recycling sewage sludge. Besides providing nutrients and organic matter to crops and soils, it is an important alternative for recycling this residue. However, problems during the sewage treatment process may generate sludge batches with an acidic pH. Thus, it is essential to understand the consequences of using such sludge on soils and plants, and to explore ways to overcome this limitation. The objective of this study was to evaluate addition rates of anaerobic sewage sludge (ASS) with acidic compositions on the soil fertility and performance of lettuce plants. Additionally, a methodology for pH correction of ASS with acidic pH is proposed. An agronomic experiment was conducted in a greenhouse using seven addition rates of ASS (0.0, 0.25, 0.5, 1, 2, 4 and 8 g kg−1 in dry basis), treated with an additional step of disinfection (solarization), and applied in an Albaqualf soil cultivated with lettuce (Lactuca sativa). Soil and leaf chemical composition, as well as chlorophyll index and the dry matter of lettuce leaves were evaluated. Failures during the acidogenesis phase of the anaerobic digestion process were probably the cause of ASS acidification. Although this ASS increased soil fertility indicators and plant dry matter, it significantly reduced soil pH, thereby requiring a complementary assay to correct its pH up to 6.0, which was achieved through liming. Anaerobic sewage sludges with an acidic pH can be effectively used in agriculture after being dried and disinfected through solarization, followed by pH correction, avoiding negative impacts on soil chemical attributes and plant response.
