Peres et al (2010) observed that the presence of 15 Mg ha -1 of sugarcane straw covering the soil reduced water loss (0-20 cm layer) by approximately half when compared to uncovered soil.…”

ABSTRACT:The use of crop residues as a bioenergy feedstock is considered a potential strategy to mitigate greenhouse gas (GHG) emissions. However, indiscriminate harvesting of crop residues can induce deleterious effects on soil functioning, plant growth and other ecosystem services. Here, we have summarized the information available in the literature to identify and discuss the main trade-offs and synergisms involved in crop residue management for bioenergy production. The data consistently showed that crop residue harvest and the consequent lower input of organic matter into the soil led to C storage depletions over time, reducing cycling, supply and availability of soil nutrients, directly affecting the soil biota. Although the biota regulates key functions in the soil, crop residue can also cause proliferation of some important agricultural pests. In addition, crop residues act as physical barriers that protect the soil against raindrop impact and temperature variations. Therefore, intensive crop residue harvest can cause soil structure degradation, leading to soil compaction and increased risks of erosion. With regard to GHG emissions, there is no consensus about the potential impact of management of crop residue harvest. In general, residue harvest decreases CO 2 and N 2 O emissions from the decomposition process, but it has no significant effect on CH 4 emissions. Plant growth responses to soil and microclimate changes due to crop residue harvest are site and crop specific. Adoption of the best management practices can mitigate the adverse impacts of crop residue harvest. Longterm experiments within strategic production regions are essential to understand and monitor the impact of integrated agricultural systems and propose customized solutions for sustainable crop residue management in each region or landscape. Furthermore, private and public investments/cooperations are necessary for a better understanding of the potential environmental, economic and social implications of crop residue use for bioenergy production.

“…In general, both treatments that retained straw (i.e., straw cover, raked) enhanced N and P concentrations in the plant tissue both early and late in the second ratoon. Increased plant nutrient concentrations may reflect the benefits of retaining straw, such as enhanced nutrient cycling (Sousa Jr. et al, 2018) and/or increased C accumulation (Galdos et al, 2017;Cherubin et al, 2018;Sousa Jr. et al, 2018), water storage and infiltration (Valim et al, 2016;Anjos et al, 2017), and biological activity (Paredes Jr. et al, 2015). Healthy soils generally have increased availability of N and P for plant uptake, which subsequently increases plant tissue concentrations of these elements when straw is retained.…”

Sugarcane Straw Blanket Management Effects on Plant Growth, Development, and Yield in Southeastern Brazil

et al. 2019

In Brazilian sugarcane (Saccharum spp.) production systems, the practice of moving harvesting residue from row to inter‐row positions (i.e., raking) has increased in response to producer concerns over the potential negative effects of sugarcane straw on crop establishment and stalk yield. Despite increasing adoption among sugarcane farmers, the impacts of straw raking practices on plant growth and yield remain unclear. A 2‐yr experiment that included both dry and wet seasons was conducted at two sites in southeastern Brazil to evaluate straw management strategy effects on plant tillering, phytomass accumulation, plant nutritional status, and stalk yield. The experiments were established at the Bom Retiro mill and the Univalem mill. Experimental treatments included raking straw to inter‐rows (raked), total straw removal (bare soil), and no straw removal (straw cover). Raked and bare soil treatments improved plant tillering but did not influence final plant population. Straw management had a slight effect on phytomass accumulation. Reduction of phytomass yield was observed from the first to the second ratoon during both seasons at both sites. At Bom Retiro, phytomass yield decreased 37% for stands established during the dry season and 19% for stands established during the wet season. At Univalem, phytomass yield decreased 20% for stands established during the dry season and 30% for stands established during the wet season. Retaining straw in the field (regardless of treatment) increased leaf tissue P content but not stalk yield. Raking straw from row to inter‐row positions at these locations in southeastern Brazil had no benefit on sugarcane yield but may result in soil compaction and higher production costs over time.

“…The main changes caused by straw on the soil surface are the following: greater efficiency in the control of erosion and increase of the organic matter content, macro and microfauna, improving the soil structure, alteration in the incidence of light on the surface; increased infiltration of water into the soil; decrease in thermal amplitude and evaporation, especially in the superficial layers (INMAN-BAMBER;SMITH, 2004;GARCIA et al, 2007;CHRISTOFFOLETI et al, 2007;CAVENAGHI et al, 2007;GUIMARÃES et al, 2008;TAVARES et al, 2010;COSTA et al, 2014;PAREDES JUNIOR et al, 2015;VALIM et al, 2016).…”

Environmental constraints, labour shortages and the search for greater efficiency have induced the mechanisation of sugarcane harvesting, providing a large amount of straw in the system, which provides benefits to the soil, the crop and the environment. The objective of this work was to evaluate the effect of the removal of different amounts of straw from the soil surface on the development and productivity of sugarcane in eutrophic Red Latosol. The experiment was conducted in an area belonging to the Usina in Bandeirantes, PR, using a randomised block design with four replications. The effects of six treatments (0, 25%, 50%, 75%, 100% of straw and sugarcane) were evaluated after four years of cultivation on the LAI (leaf area index), tillering, diameter, length and fresh mass of the stalks, in five periods: 60, 120, 180, 240 and 370 days after harvest (DAC). The results were submitted to analysis of variance and the means compared by Tukey's test. The straw on the soil surface provided benefits to the development and productivity of sugarcane. The management of sugarcane burning, total removal of the straw (0% of soil cover) or 75% of straw resulted in a lower IAF and stalk diameter and a 37% decrease in final yield under conditions of water deficiency. The maintenance of 50% of straw is sufficient to favour the development and to provide greater productivity of the sugarcane, as it is possible to use the 50% surplus of the field for the production of ethanol of second generation or electric energy, without damage to the productivity of the culture.

ResumoAs restrições ambientais, a falta de mão-de-obra e a busca por maior eficiência induzem a mecanização da colheita de cana-de-açúcar, disponibilizando grande quantidade de palhada no sistema, que proporciona benefícios ao solo, à cultura e ao meio ambiente. O objetivo desse trabalho foi avaliar o efeito da retirada de diferentes quantidades de palhada da superfície do solo sobre o desenvolvimento e a produtividade da cana-de-açúcar em Latossolo Vermelho eutroférrico. O experimento foi instalado em área pertencente a Usina em Bandeirantes, PR, utilizando delineamento em blocos casualizados com quatro repetições. Foram avaliados os efeitos de seis tratamentos (0, 25%, 50%, 75%, 100% de palhada e cana-queimada), após quatro anos de cultivo, sobre o IAF (Índice de área foliar), perfilhamento, diâmetro, comprimento médio e massa fresca dos colmos, em cinco períodos: 60, 120, 180, 240 e 370 dias após a colheita (DAC). Os resultados foram submetidos à análise de variância e as médias comparadas pelo teste Tukey. A palhada sobre a superfície do solo proporcionou benefícios ao desenvolvimento e a produtividade da cana-de-açúcar. Os manejos queima da cana-de-açúcar, retirada total da palhada (0% de cobertura do solo) ou de 75% de palhada resultaram em menor índice de área foliar, diâmetro de colmos e diminuição de 37% na produtividade final, em condições de deficiência hídrica. A manutenção de 50% de p...
