“…Verificou-se um aumento significativo de todos os caracteres avaliados com a adição do esterco caprino. Isso se deve ao fato deste substrato proporcionar o aumento significativo do teor médio de água no solo, por ser eficaz na melhoria da estrutura física do solo com a presença da matéria orgânica e atividade microbiológica (Mertens et al, 2017). O esterco caprino, por outro lado, contém elementos essenciais necessários para o crescimento das plantas, incluindo N, P, K, Ca e Mg (Mowa et al, 2018).…”

A aplicação de fertilizantes inorgânicos para aumentar o rendimento das culturas proporciona o aumento do rendimento das culturas, porém, eles contribuem para a degradação do solo. Embora estes adubos orgânicos estejam sendo promovidos como fontes de nutrientes, ainda são inferiores no fornecimento de nutrientes quando comparados com os fertilizantes inorgânicos. Isso promoveu o interesse por vários outros materiais para correção, como cinzas volantes, fosfato de rocha e biochar, bem como outros métodos, como bactérias solubilizadoras de fósforo, para aumentar o conteúdo de nutrientes no solo e melhorar a produção de mudas em condições do nordeste brasileiro. Por isso, o estudo objetivou-se em avaliar o crescimento inicial e biomassa de mudas de melão amarelo produzidas em diferentes substratos, visando determinar os meios de cultivo adequados e alternativos para a cultura de melão amarelo. O estudo foi conduzido em delineamento inteiramente casualizado, com quatro tratamentos (Biocarvão, Casca de arroz carbonizado, Esterco Caprino e Substrato Comercial) e cinco repetições. Avaliou-se a altura da plântula, diâmetro de caule, comprimento da raiz (CR), massa seca da parte aérea, massa seca da raiz e massa seca total. Inicialmente os dados foram submetidos ao teste de normalidade de Shapiro-Wilk e em seguida submetidos à ANOVA pelo teste F. Quando significativo, as médias foram comparadas pelo teste de Tukey (p ≤ 0,05) através do software Assistat na versão 7.7. A ANOVA foi significativo para todas as variáveis avaliadas, exceto o comprimento da raiz. Os três substratos: esterco caprino, substrato comercial e biocarvão promoveram melhor crescimento e desenvolvimento inicial das mudas de melão amarelo. O esterco caprino proporcionou melhores resultados para DC, MSR e MST. O Substrato Comercial proporcionou melhores resultados para as variáveis AP e MSPA, enquanto que o Biocarvão apenas para a variável AP. O substrato casca de arroz carbonizada apresentou os menores valores em todas as variáveis analisadas para as mudas de melão amarelo.

“…A BC made from E. marginata decreased soil microbial carbon in a coarse soil [31], and BC added to a sandy desert soil did not significantly change soil physical properties [32]. Two BC types had different impacts on growth of young Pinus elliottii in subtropical China [33]. Varying doses of macadamia BC combined with two fertilizer rates had contrasting results on soil nutrients and ambiguous trends in the growth of young E. nitens [34].…”

Eucalypts can be very productive when intensively grown as short rotation woody crops (SRWC) for bioproducts. In Florida, USA, a fertilized, herbicided, and irrigated cultivar planted at 2471 trees/ha could produce over 58 green mt/ha/year in 3.7 years, and at 2071 trees/ha, its net present value (NPV) exceeded $750/ha at a 6% discount rate and stumpage price of $11.02/green mt. The same cultivar grown less intensively at three planting densities had the highest stand basal area at the highest density through 41 months, although individual tree diameter at breast height (DBH) was the smallest. In combination with an organic fertilizer, biochar improved soil properties, tree leaf nutrients, and tree growth within 11 months of application. Biochar produced from Eucalyptus and other species is a useful soil amendment that, especially in combination with an organic fertilizer, could improve soil physical and chemical properties and increase nutrient availability to enhance Eucalyptus tree nutrition and growth on sandy soils. Eucalypts produce numerous naturally occurring bioproducts and are suitable feedstocks for many other biochemically or thermochemically derived bioproducts that could enhance the value of SRWCs.

To accomplish organic nourishment for the fleetly growing population in India can hold creating purposeful events at fostering the wise use of organic manures in crop productivity. Soil is one in all the foremost necessary physical factors dominant the flow and preservation of water, solutes, gases and biota in agriculture and natural environment. An understanding of physical condition of any soil is crucial for implementation of variable fields across the landscape. The field work is designed in South India of Tamil Nadu by planting the sweet corn at Karisalpatti village, Tirunelveli in 2018. It is gauged using single, double and triple manure combination of amendment at varied concentration to evaluates the physical properties of sandy loam soil. The field was set to go in randomised block style with 3 replications. A considerable enhancement in well being of soil was ascertained with reference to nourishing the convenience of physical steadiness using vermicompost manure. The increase in porosity has been attributed to extend the amount of pores within the soil. The physical changes of soil due to the time and temperature was assistance by thermo gravimetric and differential thermal methodology. Fourier transform infrared spectroscopy confirms the presence of organic mineral inside the soil. UV-Diffuse reflectance spectroscopy works out the structure and colourizes the sandy soil. Characterize the electrochemical system of soil using Cyclic Voltammeter spectroscopy. The result shows that thanks to the addition of organic manure there's robust OH bond absorption and stumps up high yield contribution to corn crop.
