“…This result can be explained by the high lignin content contained in this organic waste (ZOCA et al, 2014), which hampers decomposition and humus formation in the soil. Souza et al (2014) found no changes in the organic matter content of the 0 -20 cm soil layer after five years of surface applications of rates up to 36 t ha -1 of waste generated by the guava processing industry, consisting basically of seeds of the fruit. In the 0 -5 cm layer of an area of producing coffee plants, Silva et al (2015) found a linear increase in organic C content, and consequently of soil organic matter, in response to surface applications of organic compound containing coffee husk.…”

Coffee processing generates large amounts of husk, which can be used as organic fertilizer if technical criteria are considered. This study investigated the effect of coffee husk, applied to or incorporated into the soil, on soil fertility properties, early crop growth and nutrient accumulation in coffee plants. The experiment analyzed coffee plants in a greenhouse in pots, in randomized blocks, in a 5x2 factorial arrangement plus a control treatment, with four replicates. The treatments consisted of the combination of five coffee husk rates (3.5; 7; 14; 28, and 56 t ha-1), applied in two forms: spread on the surface or incorporated into the soil, plus the control treatment, without husk application. Portions of 7 dm 3 soil were blended with lime, phosphate fertilizer, as well as coffee husk rates in the treatments with residue incorporation, and incubated for 30 days. Thereafter, one coffee seedling per plot was planted, the coffee husk rates were applied on the soil surface for the treatments without residue incorporation, and the plants were left to grow for 180 days. Coffee husk applied to or incorporated into the soil surface increases the K and organic matter contents of the soil, intensifies the early growth of coffee plants and accelerates N and K accumulation in the plant shoots. The application of coffee husk on the surface is more indicated than its incorporation into the soil, and the best rate at coffee planting is equivalent to 20 t ha-1 .

“…Com o incremento das doses do subproduto, houve aumento das concentrações de fósforo no solo ao longo dos anos, conforme relatado na Parte I deste artigo (SOUZA et al, 2014). Entretanto, esse aumento de P no solo do pomar não alterou os teores foliares de fósforo nas plantas.…”

RESUMO -O conhecimento sobre a dinâmica dos nutrientes provenientes da aplicação de resíduos orgânicos faz-se necessário, principalmente visando sua a reciclagem, considerando que a quantidade desses materiais tem aumentado rapidamente com o tempo. Assim, objetivou-se avaliar o estado nutricional e a produção de frutos de um pomar de goiabeiras, em função da aplicação do subproduto da indústria processadora de goiabas. O delineamento empregado foi o de blocos casualizados, com cinco tratamentos e quatro repetições, sendo as doses do subproduto (moído) iguais a zero; 9;18; 27 e 36 t ha -1 (peso do material seco). Foram feitas cinco aplicações do subproduto em 2006, 2007, 2008, 2009 e 2010. Avaliou-se o estado nutricional das goiabeiras, via diagnose foliar (macro e micronutrientes), bem como a produção de frutos por seis safras consecutivas. A aplicação do subproduto da indústria processadora de goiabas promoveu alterações no estado nutricional e na produção de frutos. As doses do subproduto incrementaram os teores foliares de N, Mg e Mn da goiabeira. A produção de goiabas cresceu de forma linear em função das doses do subproduto. Os efeitos da aplicação do subproduto foram verificados primeiramente no solo, posteriormente nos teores foliares e, finalmente, na produção de frutos, ao longo das safras.

AGRONOMIC USE OF BY-PRODUCT OF GUAVA PROCESSING INDUSTRY -II -NUTRITIONAL STATUS AND PRODUCTIONABSTRACT -The knowledge about the dynamics of nutrients from the application of organic waste is needed, especially in order to recycle, since the quantity of these materials has increased rapidly over time. Thus, this study aimed to assess the nutritional status and yield of guava, depending on application of by-product from the guava processing industry. The experimental was a randomized block design with five treatments and four replications, the doses of by-product were equal zero, 9, 18, 27 and 36 t ha -1 (dry weight of the material). There were five applications of waste in 2006, 2007, 2008, 2009 and 2010. It was evaluated the nutritional status of guava (macronutrients and micronutrients), as well as fruit production for six consecutive years. The application of by-product in guavas processing industry promoted changes in the nutritional status and fruit production. Doses of by-product increased foliar content of N, Mg and Mn. Fruit yield increased linearly as a function of residue doses. The effects of the by-product were observed primarily in the soil, then in the leaf contents and finally in the production of fruits along the seasons.

“…The increase in the agroindustrial activity has led to the generation of large quantities of waste in the last decades, which, when disposed in an inadequate manner, can have negative impacts on the environment (Souza et al, 2014). The composition of these residues depends on the raw material, but many of them have potential for use in agriculture, and employment according to technical criteria presents benefits, such as the supply of nutrients to the plants and the correction of soil acidity (Guimarães et al, 2012).…”
