“…Besides, the residues selected (aquatic macrophytes and ash sugarcane bagasse) were chosen due to their abundance in the study region. Aquatic macrophytes cause problems in energy-generating in the hydroelectric power plants [ 17 ], and also the region has become a major producer of sugar cane, consequently, sugar, alcohol, and residues such as bagasse, cane straw, and bagasse ash, require an alternative for disposal [ 18 ]. Combining biomass residue amendments with the reintroduction of native vegetation, which add appropriate leaves, root biomass, and root exudates, further bolster soil functioning [ 19 ].…”

Revegetation of exposed sub-soil, while a desirable strategy in the recovery processes, often fails due to extreme soil chemical properties, such as low organic matter and pH levels inhospitable to biological activities such as nutrients cycling and plant establishment. This is the case for approximately 800 ha of the Cerrado biome in Brazil, where erecting the embankment of a hydroelectric dam in the 1960’s stripped vegetation, soil, and subsoil layers thereby distorting the soil properties. This work evaluates the effectiveness of restoration management (RM) treatments, to restore the soil quality, including biological activity and chemical attributes. In a factorial scheme, RM treatments include the addition of organic residue from aquatic macrophytes (AM) at 3 rates (0, 16 and 32 t ha-1), combined with ash from sugar cane bagasse of agroindustrial origin (BA) at 4 rates (0, 15, 30 and 45 t ha-1). RM samples contrasted samples collected from undisturbed Cerrado (CER) as well as a degraded area without intervention (DAWI). The mechanized RM plots received amendments and reforestation of 10 Cerrado native tree species. After 5 years, vegetation covered up to 60% of the surface in RM treatments receiving AM32 + BA45. AM and BA residues promoted height increases in the introduced plants. All RM treatments promoted lower levels of Al3+ than DAWI and CER. The combination of AM32 over the rates of incorporated ash increased soil pH and K values similarly to CER. Microbial-related variables, such as microbial biomass-C was the largest in CER, followed by the RM treatments, and the lowest in DAWI. The microbial quotient was no different between CER and RM treatments. The addition of residues such as AM and BA increased the vegetation covered, improved chemical and microbiological indicators. Thus, the residues used aided the recovery process of intensely degraded soils in the Cerrado area.

“…Soil today is well known as nonrenewable natural resource at least on a human lifespan because once soil has degraded, its rejuvenation is definitely a very slow process (Lal, 2015;Abd El-Azeim et al, 2020). Soil quality and productive capability can be deteriorated with long-term irrigated sugarcane monoculture (Martíni et al, 2020;da Silva et al, 2021;Taleisnik and Lavado, 2021;Marin et al, 2021). Sugarcane (Saccharum hybrid sp.)…”

“…In addition, there are growing concerns about agricultural sustainability and the environment, with recent farming systems adversely affecting long-term sugarcane productivity of soil due to the loss of soil organic matter (SOM) and increases in erosion (Alhameid, et al, 2019;Martíni et al, 2020;da Silva et al, 2021) accompanied by fertility loss and soil degradation in many cases. Therefore, alternative management systems that are more diverse and create less disturbance to the soil have been promoted to enhance soil properties, and consequently farm productivity.…”

“…In Egypt, nearly 25 million tons of rice straw and sugarcane trashes are being yearly burned in the open fields, making a strong contribution to climate change (Omran and Negm, 2020). Studies have indicated that conventional soil tillage practices for the monoculture of sugarcane may cause a loss equal to 80% of the organic carbon that can be accumulated in the soil rhizosphere within one year of motorized harvesting during a period of only 44 days (Martini et al, 2020;Omran and Negm, 2020;da Silva et al, 2021).…”

Soil deterioration and yield decline are the main factors affecting the environmental sustainability of long-term irrigated sugarcane monoculture. This research was conducted to detect changes of soil physical, chemical and physicochemical quality parameters associated with intensive irrigated sugarcane monoculture with groundwater for long term. Sugarcane monoculture resulted in a severe impact on some soil physical indicators of soil quality as increased the soil bulk density and reduced soil clay content, decreased soil aggregate stability and the water content at the field capacity causing decreases in soil porosity and decline in soil fertility. Significant impacts on some soil chemical indicators of soil quality were also recorded as reduced soil organic matter content and increased soil pH and EC producing soil salinity. Fields under long-term irrigated sugarcane monoculture had low OM values ranged from 2.09 to 2.61% while areas under crop rotation had the highest OM values ranged from 2.62 to 3.39%. Fields under sugarcane monoculture system had higher pH, EC and SAR values ranged from 7.96 to 8.41, from 2.98 to 4.22 dS m -1 and from 7.75 to 11%, while fields under crop rotation system had the lowest pH, EC and SAR values ranged from 7.64 to 7.92, 1.41 to 2.42 dS m -1 and from 4.51 to 5.86%, respectively. From these results, it could be concluded that long term sugarcane monoculture has significantly deteriorated soil physical and chemical properties indicating the urgent demand for more sustainable management practices to preserve soil quality.

“…Ao longo dos últimos anos as mudanças climáticas globais vêm trazendo alguns eventos climáticos extremos e alterações na dinâmica climática em patamares não registrados historicamente. Para cana-de-açúcar é preciso revisitar os modelos e zoneamentos históricos da cultura e entender se as mudanças climáticas foram responsáveis por uma alteração na dinâmica espacial da produção (SILVA et al, 2021).…”

A Agricultura Digital é uma abordagem multidisciplinar que diz respeito ao uso de informações digitais detalhadas para orientar a tomada de decisão ao longo da cadeia agrícola. Seu uso é cada vez mais necessário e deve trazer muitos benefícios para a segurança alimentar e energética nos próximos anos. O grande ponto é a aquisição de dados de maneira contínua para gerar informações e guiar processos. Como a agricultura, principalmente no Brasil, é feita em grandes escalas de área e por conta disso, a aquisição de dados com o uso de sensores na propriedade é dificultada, o sensoriamento remoto aparece como uma ferramenta importante para a obtenção de dados e validação de operações. O sensoriamento remoto é utilizado de forma contínua desde a década de 80, porém tem ganhado mais força com o aparecimento da computação de alta performance e com o barateamento dela. Embora em algumas culturas estejam bastante desenvolvidas no uso de sensoriamento remoto para geração de informações, a cana-de-açúcar ainda possui poucos trabalhos e em escala local. A cana-de-açúcar é a principal cultura para a produção de açúcar e etanol no Brasil. O país é responsável por mais da metade da produção mundial dessa planta e hoje ela é cultivada no Nordeste e na região Centro-Sul. Devido à extensa área de cultivo, existem diversas condições edafoclimáticas em que a cultura da cana-de-açúcar se desenvolve e desta forma, separar essas regiões é extremamente importante para poder aplicar modelos em escala homogênea. Além disso, fazer uma separação morfológica dos canaviais é importante para não gerar modelos sem essa variável e consequentemente trazer incertezas ao processo. No intuito de criar regiões homogêneas foi feito um trabalho de zoneamento e regionalização levando-se em conta as variáveis agrometeorológicas, solo e produtividade histórica da cana planta. Criou-se três regiões de alto, médio e baixo potencial de produção de cana para o Centro-Sul do país. Em seguida, avaliando-se o comportamento histórico de índices de vegetação da área de estudo, fez-se uma regionalização levando em conta o potencial de produção e o comportamento do índice de vegetação. Foram propostas dezessete regiões com comportamento homogêneo para aplicações de modelos baseados em sensoriamento remoto. Outra abordagem foi identificar características morfológicas da cana-de-açúcar que podem levar a falhas em modelagens de áreas contínuas. Para isso, foi utilizado o modelo Random Forest e imagens do satélite Sentinel-2 para criar um modelo que identifica diferentes cultivares. O modelo teve uma precisão global de 86% e índice kappa de 81%. Quando aplicado para 4 cultivares em uma região maior, apresentou a precisão variando de 91% a 96%. Desta forma, foi possível concluir que modelos se adaptam com a mesma precisão que o conjunto de treino, se a região de aplicação é homogênea em relação a solo, clima e manejo. Além disso, o trabalho é base para futuras aplicações em agricultura digital para a cultura da cana-de-açúcar que precisem gerar modelos para a região Centr...
