Duas propostas de sistemas agroflorestais foram implantadas em 1993, em tres propriedades rurais, no municipio de Presidente Figueiredo, AM, em arranjos com os seguintes componentes: perenes - cupuacu (Theobroma grandiflorum), pupunha (Bactris gasipaes) e inga (Inga edulis), e semiperene - banana (Musa ssp). Nos espacos disponiveis, foram testados arranjos sequenciais de componentes anuais: Sistema I- mandioca (Manihot esculenta), caupi (Vigna unguiculata) e mandioca; Sistema II- arroz (Oryza sativa), caupi e mandioca, ambos testados com adubacao NPK, P e P + leguminosa. A biomassa da parte aerea vegetal da capoeira com dois anos (cerca de 4t/ha) promoveu, apos a queima, aumento significativo nos teores de nutrientes do solo, mas nao o suficiente para promover o bom desenvolvimento das culturas. A producao das culturas no primeiro ciclo, em tratamento com adubacao, correspondeu a cerca de 58%, 78% e 100% das producoes totais de mandioca, caupi e banana, respectivamente, e as receitas representaram quase cinco vezes a soma dos valores obtidos nos demais tratamentos. De acordo com os resultados esses sistemas apresentam perspectivas economicamente viaveis, demonstrando tendencia de sustentabilidade a longo prazo. |

Sewage sludge contains plant nutrients and organic matter in its composition, making it a potential partial substitute for mineral fertilizers if it meets environmental, agronomic, and sanitary standards. The objective was to evaluate the content of nutrients and heavy metals in the sludge generated in four wastewater treatment stations (WWTPs) in Rio de Janeiro state and assess its potential value and usefulness. The samples of 19 batches from the WTTPs Alegria, Barra da Tijuca, Ilha do Governador, and Sarapuí were analyzed. The WWTPs differ in methods and processes used for treating sewage and sludge. The total contents of C, N, P, K, Ca, Mg, Fe, Al, Na, Co, Mn, As, Ba, Cd, Cr, Cu, Ni, Se, Pb, and Zn were evaluated, as well as the ratio C/N, pH, organic matter content, and electrical conductivity. The grouping of sludge samples was assessed using principal components (PCA) and cluster analysis. The economic valuation of sludge was conducted utilizing the substitute goods method, which compared the sludge’s N-P-K contents with the prices of consolidated nutrient sources. All the evaluated sludge batches exhibited concentrations of heavy metals below the limits allowed by Brazilian law, along with high levels of nutrients and organic matter. Considering the chemical characteristics, all evaluated materials showed potential for agricultural use, but it is crucial to evaluate the microbiological characteristics of sludge batches before agriculture application. PCA and cluster analysis demonstrated that sludge samples from the same WWTP clustered close to each other, demonstrating higher similarity among themselves than with samples from other WWTPs. The sludge had an average added value of U$ 88.46 per megagram, considering the total contents of N, P, and K in its composition. Land application of sewage sludge can reduce the need to purchase mineral fertilizers, thereby supporting the feasibility of reusing this material in the agricultural sector.
