“…The lowest bulk density in the surface layer of DC is due to the greater contribution of organic matter by the necromass (dead trees and litter) [26] in the surface layer. In general, organic residue has a lower specific weight compared to the mineral fraction [27].…”

Land-Use Effect on Soil Carbon and Nitrogen Stock in a Seasonally Dry Tropical Forest

et al. 2020

Total organic carbon (TOC) and total nitrogen (TN) concentration in the soil are an indicator of soil degradation. To understand how land-use may impact these concentrations in seasonally dry tropical forests (SDTF), we analyzed the effect of four land-uses on TOC stocks (STK.TOC) and TN stocks (STK.TN) in a semi-arid region of Brazil. Soil samples were collected in 12 trenches (three sites × four land-uses—dense caatinga (DC), open caatinga (OC), pasture (PA) and agriculture (AG)), in the 0–10; 10–20 and 20–30 cm layers or as far as the bedrock. The data were compared by the Kruskal–Wallis test (p ≤ 0.05) and similarity investigated by cluster analysis. STK.TOC and STK.TN the surface layer (0–10 cm) showed no significant difference (p ≤ 0.05) between the DC; OC and PA land-uses. The similarity in STK.TOC and STK.TN values between DC, OC and PA, indicate that it is possible to explore SDTF to produce biomass and protein by adopting open caatinga and pasture land uses on Neosols with very low TOC stocks. The greatest reduction in STK.TOC and STK.TN in the agriculture land-use may lead to soil degradation and contribute to the addition of CO2 to the atmosphere.

“…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.…”

“…extract antioxidant compounds, used in the food, cosmetic and pharmaceutical industries (GARCIA and BIANCHI, 2015); as bedding in confinement facilities of animals (MATIELLO et al, 2010); and for power generation by direct burning, in industrial furnaces or in coffee bean dryers (SATER et al, 2011). However, for being a source of nutrients, in particular of K (HIGASHIKAWA; SILVA; BETTIOL, 2010), it is largely used in agriculture, as a substrate component for seedling production (ASSIS et al, 2011), in organic compost (SILVA et al, 2015), or mainly as organic fertilizer of coffee plants (FIDALSKI and CHAVES, 2010;FERNANDES et al, 2013).…”

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 .

“…Para alface foi confirmado os efeitos benéficos da adição de composto orgânico com aumento na massa e nos teores de nutrientes (ABREU et al 2010; SHAHEIN; AFIFI; ALGHARIB, 2014), sendo encontrado valores superiores a 40% na produtividade, em comparação ao controle (SEDIYAMA et al, 2016). Desta forma, o efeito residual da matéria orgânica adicionada pode ocorrer a longo prazo sobre culturas cultivadas em sucessão (DINIZ et al 2017;LANNA et al 2018) ou a médio e pequeno prazo sobre a cultura implantada após a adição do composto (CANDIAN;CARDOSO, 2015;SILVA et al 2015), conforme observados no acúmulo de massa nas plantas de T. triangulare e T. paniculatum (Tabelas 4 a 5).…”

Espécies do gênero Talinum apresentam folhas com importantes características nutricionais, o que favorece sua utilização para alimentação humana. T. triangulare e T. paniculatum são encontradas em todo Brasil como planta daninha, todavia nas regiões Norte, Nordeste e Centro-oeste são comercializadas como hortaliça não convencional. Objetivou-se, com este estudo, mensurar a produção de T. triangulare e T. paniculatum em função de doses de adubação de composto orgânico. Foram testados cinco níveis de adubação (0, 30, 60, 90 e 120 t ha-1 de composto orgânico) mais uma testemunha, representada por adubação inorgânica na dose de 600 kg ha-1 da formulação 04-14-08. Após o transplantio das mudas de ambas as espécies em canteiros foram feitas três colheitas, aos 50, 105 e 160 dias e para massa seca das folhas (MSF), de caule (MSC), de estrutura reprodutiva (MSER) e a parte aérea (MSPA) verificaram-se incrementos lineares às doses do adubo orgânico. Após o primeiro corte, as maiores doses de composto orgânico (60, 90, e 120 t ha-1) proporcionaram maior produção de folhas em relação à testemunha de adubação inorgânica. Foram encontradas correlações positivas e altamente significativas entre as variáveis altura de plantas (AP), número de folhas (NF), número de ramos (NR), MSF, MSC, MSER e MSPA. O efeito residual da adubação orgânica favorece a produção de hortaliças folhosas não convencionais.
