“…Tal planejamento irá abordar desde a seleção de áreas com elevado potencial produtivo a cultivares a serem utilizadas e aos insumos de uso previsto durante a safra. Ainda na análise, deverá ser considerada a textura do solo, optando por solos de textura média a argilosa em razão, principalmente, da elevada sensibilidade do algodão a solos compactados, mal drenados e com baixa oxigenação (Bennet et al, 2015;Jamali et al, 2021;Otto et al, 2023).…”

A obra que apresentamos conta com uma variedade de capítulos que abrangem diferentes áreas da ciência florestal e agrícola, fornecendo um panorama amplo dos temas abordados. Desde a descrição morfológica e caracterização anatômica do colmo maduro do bambu gigante da Amazônia (Guadua aff. lynnclarkiae) até a viabilidade econômica da geração distribuída e compartilhada de energia elétrica com biomassa florestal, os capítulos apresentam uma riqueza de informações valiosas para pesquisadores, estudantes e profissionais das áreas afins. Os capítulos sobre as dimensões de fibras em árvore de Corymbia citriodora com lenho de reação, as contribuições da agroecologia para a construção de um novo direito agrário brasileiro e as considerações sobre a modificação térmica para a melhoria da qualidade do piso de deck de madeira, fornecem conhecimentos específicos e aplicáveis em suas respectivas áreas. O estudo de caso sobre as parcerias empresariais para a criação de consórcio de geração de energia elétrica, por sua vez, oferece uma perspectiva prática e atualizada sobre a gestão de recursos energéticos. A descrição dendrométrica de povoamento de araucária no instituto federal do sudeste de Minas Gerais, o cultivo do algodão de ponta a ponta com manejo fitotécnico, nutricional e fisiológico, a ecofisiologia da germinação e produção de mudas de jatobazeiro, o estudo fitoquímico da Melochia tomentosa L. (Malvaceae) e a aplicação de biofertilizante de polpa de café no desenvolvimento morfológico da cultura de alface (Luctuca sativa L.) complementam a obra com suas contribuições valiosas para a compreensão dos aspectos biológicos e culturais da produção agrícola e florestal. Em suma, esta obra é uma fonte rica e completa de informações sobre ciência florestal e agrícola, apresentando estudos, pesquisas e estudos de caso que contribuem para o desenvolvimento dessas áreas e para a gestão sustentável dos recursos naturais.

“…According to the results of this experiment, the soil compaction by land rolling significantly increased barley canopy temperature. However, it is known that the higher canopy temperature shows that the transpiration rate was less due to lower soil water content, and higher canopy temperature results in a faster rate of stress accumulation (Jackson et al 1988;Jamali et al 2021). In this case, the higher Canopy Temperature at higher land roller weights means lower water content in soil and a faster rate of stress accumulation during the heading stage of barley.…”

This study aimed to determine the changes in soil properties due to land rolling after sowing and analysis the effects of these changes in soil properties on the plant growth in barley (Hordeum vulgare L.) production. For this purpose, a field experiment was conducted by using three weights of the land roller (196.37, 337.67, 478.97 kg/m) and untreated control treatment after sowing barley. The results showed that land rolling significantly changed the soil properties such as bulk density, moisture content, and penetration resistance. These changes in soil conditions significantly affected the plant growth parameters in barley production. The increased bulk density at the 0 ‒ 100 mm depth of the soil due to land rolling increased the seed emergence, the plant growth parameters and the yield of barley. However, it was observed that the grain yield per ear started decreasing at the higher penetration resistance than 345, 486, and 630 kPa for 50 mm, 75 mm and 100 mm, respectively. Consequently, it can be said that the use of a land roller after sowing in barley production can increase the yield by improving the plant growth parameters and soil physical properties under the soil and climate conditions like the experimental field.

“…The latter leads to over-compaction of the soil in the depth of the arable layer and the subsurface horizon. The compaction extends to the subsurface layer up to 40 cm, and on moist soils the degree of compaction is greater [4]. The need for further research on reducing soil compaction by WMEV engines is discussed in [5], by chain-track tractor is discussed in [6], by track-wheel-terrain interaction is discussed in [7].…”

The performance indicators of wheeled arable machine-tractor units, which are accelerated on the working gear, depend on the operating modes of the wheels during this period. When the wheel is skidding, soil lumps break down in the contact spot, the soil structure is destroyed. Based on the system analysis of the wheels operation, the method of their improvement is justified by continuous control of the eccentric point of application of the driving torque and external load. As a result of the analysis for the first time, a soil-sparing wheel mover with the properties of a differential, a tangential force regulator and clearance regulator was developed. In the case of an eccentric application of a vertical load and a longitudinal pushing force, one of the satellites of the wheeled planetary gearbox is the leading and bearing one. The purpose of the article is to analyze the factors influencing the automatic adaptation of the wheel drive to changing operating conditions. It is established the relationship between the driving moment and the rolling resistance moment, the moments of inertia of the wheel and the drive gear of the integrated differential.
