Abstract: Improving soil fertility with organic sources is crucial, particularly in degraded regions. Organic fertilizers, when integrated into systems, provide cost-effective solutions. This study aimed to assess the impact of various organic fertilizers on the establishment of an agroforestry system in Planosol in a semi-arid region of Ceará State, Brazil. We used a randomized block design arranged in split plots. Four organic fertilizer sources (sheep manure, cattle manure, carnauba palm straw, and control) were assigned to the main plots. Evaluation years for annual crops (2015, 2017, and 2019) and for trees (2015 through 2017, and 2019) were allocated to subplots, with three replicates. All organic fertilization sources received an annual rate of 10 t ha-1, broadcasted uniformly. Experimental plots, spanning 18 x 7 m, were intercropped with maize and cowpea between rows of trees (Mimosa caesalpiniifolia and Spondias mombin). We examined soil fertility, tree growth, and crop grain yield. Soil chemistry, notably P and K, showed marked improvement with sheep manure. Organic fertilization did not enhance tree growth in the newly established agroforestry system. However, organic fertilization elevated maize and cowpea grain yields by over 60% and 90%, respectively, compared to the control. In conclusion, the use of sheep manure, cattle manure, and carnauba palm straw can significantly boost maize and cowpea grain yields in an agroforestry system found in the semi-arid region of Ceará, Brazil.
Resumo: Melhorar a fertilidade do solo com fontes orgânicas é crucial, especialmente em regiões degradadas. Os fertilizantes orgânicos, quando integrados em sistemas, proporcionam soluções económicas. Este estudo teve como objetivo avaliar o impacto de diversos fertilizantes orgânicos no estabelecimento de um sistema agroflorestal em Planossolo, no semiárido do Estado do Ceará, Brasil. Utilizou-se delineamento em blocos casualizados dispostos em parcelas subdivididas. Quatro fontes de fertilizantes orgânicos (esterco ovino, esterco bovino, palha de carnaúba e controle) foram atribuídas às parcelas principais. Os anos de avaliação para culturas anuais (2015, 2017 e 2019) e para árvores (2015 a 2017 e 2019) foram alocados em subparcelas, com três repetições. Todas as fontes de adubação orgânica receberam uma taxa anual de 10 t ha-1, distribuída uniformemente. Parcelas experimentais, medindo 18 x 7 m, foram consorciadas com milho e feijão-caupi entre fileiras de árvores (Mimosa caesalpiniifolia e Spondias mombin). Examinamos a fertilidade do solo, o crescimento das árvores e o rendimento dos grãos. A química do solo, especialmente P e K, mostrou melhoria acentuada com esterco de ovelha. A fertilização orgânica não melhorou o crescimento das árvores no sistema agroflorestal recentemente estabelecido. No entanto, a fertilização orgânica elevou a produtividade de grãos de milho e feijão caupi em mais de 60% e 90%, respectivamente, em comparação com o controle. Concluindo, o uso de esterco ovino, esterco bovino e palha de carnaúba pode aumentar significativamente a produtividade de grãos de milho e feijão-caupi em um sistema agroflorestal encontrado na região semiárida do Ceará, Brasil.

The objective of the present study was to investigate the reduction of mobility, availability and toxicity found in soil contaminated with lead (Pb) and cadmium (Cd) from Santo Amaro Municipality, Bahia, Brazil using two combined methods, commonly tested separately according to the literature: metal mobilization with phosphates and phytoextraction. The strategy applied was the treatment with two sources of phosphates (separately and mixed) followed by phytoremediation with vetiver grass (Vetiveria zizanioides (L.)). The treatments applied (in triplicates) were: T1-potassium dihydrogen phosphate (KH2PO4); T2-reactive natural phosphate fertilizer (NRP) and; T3-a mixture 1:1 of KH2PO4 and NRP. After this step, untreated and treated soils were planted with vetiver grass. The extraction procedures and assays applied to contaminated soil before and after the treatments included metal mobility test (TCLP); sequential extraction with BCR method; toxicity assays with Eisenia andrei. The soil-to-plant transfer factors (TF) for Pb and Cd were estimated in all cases. All treatments with phosphates followed by phytoremediation reduced the mobility and availability of Pb and Cd, being KH2PO4 (T1) plus phytoremediation the most effective one. Soil toxicity however, remained high after all treatments |
